It is organized as a fellowship of autocephalous (self-governing) churches that share a common faith, sacramental life and liturgical tradition, with the Ecumenical Patriarch of Constantinople holding a primacy of honour rather than universal jurisdiction. It is one of the largest Christian communions and is distinct from the Catholic Church, from which it separated in the Great Schism of 1054, and from the Oriental Orthodox churches, which rejected the Council of Chalcedon.\n\nIts history is closely tied to the Byzantine Empire and to the peoples later converted by Byzantine missionaries, including the Slavs, Georgians and Romanians. Orthodox churches have shaped national identities in Greece, Russia and the Balkans, and they have survived Ottoman rule, Soviet persecution and modern political conflict. Its theology, which stresses the Trinity, the deification of humans (theosis) and the distinction between God's essence and energies, has also shaped Christian thought and philosophy more broadly.\n\nThis entry covers the origins and early councils, the Byzantine and Ottoman periods, the 1054 schism, core doctrines and worship, icons and sacred art, monasticism, church organization and authority, the modern history of Orthodox churches in Russia and beyond, current jurisdictional disputes, social teaching, intellectual contributions, and relations with other Christian traditions." }, { "heading": "Name, definition and self-understanding", "text": "\"Orthodox\" comes from Greek roots usually rendered as \"right belief\" and \"right glory,\" so the word links correct doctrine with correct worship. In the Greek-speaking Christian world, the term traditionally designated communities or individuals who preserved the true faith as defined by the councils, as opposed to those declared heretical. The label therefore describes a claim to continuity with the early councils, not only a set of opinions. The Church's own liturgical and canonical texts use the designation \"the Orthodox Catholic Church\" (gr. catholicos = universal). The added qualifier is meant to separate it from the Roman side of the Western Church. The official designation is actually Orthodox Catholic Church to set it off from the Roman Catholic church.\n\nThe term became attached to this tradition through the division of medieval Christianity. In the year 1054 a major split occurred in Christianity. The churches in Western Europe, under the authority of the pope at Rome, separated from the churches in the Eastern Roman (or Byzantine) Empire, under the authority of the patriarch (bishop) of Constantinople. Those eastern churches have come to be known by the collective term Eastern Orthodoxy.\n\nThe Orthodox describe their church as the one, holy, catholic and apostolic church, and regard it as the historical continuation of the community founded by Christ and the apostles. Its self-understanding rests on the Nicene-Constantinopolitan Creed, which the Orthodox read as affirming a church unbroken from the apostles despite historical trials. Within that framework the Orthodox accept seven ecumenical councils—Nicaea I (325), Constantinople I (381), Ephesus (431), Chalcedon (451), Constantinople II (553), Constantinople III (680–681), and Nicaea II (787). The Orthodox do not recognize the later councils that Roman Catholics count. The difference is visible in numbering: the next council is the Fourth Council of Constantinople (869) for the Catholic Church, but the Fourth Council of Constantinople (879) for the Eastern Orthodox. Nicaea II is therefore the last council in which Orthodox and Catholics both recognize ecumenical authority, and it is the point at which the Orthodox consider the conciliar sequence closed.\n\nThe name also needs to be distinguished from two other families of churches. In the West, the term \"oriental\" is often used as a synonym for \"eastern.\" When it comes to religious traditions, however, the two words denote different churches. Oriental Orthodox churches are distinct from those referred to as the Eastern Orthodox Church. The Oriental Orthodox, including the Coptic, Syriac, Armenian and Ethiopian churches, recognize only the first three ecumenical councils—the First Council of Nicaea, the First Council of Constantinople and the First Council of Ephesus. They rejected the decisions made at the Council of Chalcedon which followed in 451. For this reason they are often called non-Chalcedonian. They are not in communion with the Oriental Orthodox Church. Eastern Catholic churches form a third category. They are fully Catholic, they subscribe to the same doctrines and recognize the same Vicar of Christ but have their own Canon Law and their own liturgical customs. The Eastern Orthodox, by contrast, are a communion of independent national churches who accept the first seven Ecumenical Councils and who separated from the Catholic Church during the eleventh century. They have seven valid Sacraments and share the same faith as the Western Church but do not accept the authority of the Pope.\n\nThe English term \"Eastern Orthodox\" is the standard label in English-language scholarship and reference works, and it groups the Byzantine-derived churches that share a common sacramental and canonical structure. Its status among the Orthodox themselves is contested. Many Orthodox writers prefer \"Orthodox Church\" or \"Orthodox Catholic Church,\" arguing that \"Eastern\" makes the tradition sound like a regional variant of Christianity rather than the continuation of the whole undivided church. Others accept the qualifier as a convenient way to distinguish their churches from the Western and Oriental families. Because the word \"oriental\" has a different meaning in religious contexts, the distinction between the names must be kept clear in scholarly writing." }, { "heading": "Apostolic roots and the early ecumenical councils", "text": "Early centres of the Church\n\nBefore any formal system of patriarchs existed, the Christian Church was organized as an indefinite number of local churches that initially looked to Jerusalem as its main centre and point of reference. Jerusalem's bishops later gained extra standing because the city held the holy places and drew pilgrims. The Council of Nicaea (325) gave the see an honorary primacy while preserving the metropolitan rights of Caesarea. Orthodox tradition links the other centres with apostolic founders: Peter at Antioch, Mark at Alexandria and Andrew at Constantinople, while Rome is associated with Peter and Paul. Constantinople's later prominence rested on its political role, since as the imperial capital it became the leading see of the East.\n\nThe Pentarchy\n\nThe notion of five leading sees grew out of their practical weight rather than a single legal decision. Their influence came mainly from political and ecclesiastical importance, and the idea of their exclusive authority was attached to older Hellenistic notions of administration. Justinian I gave the arrangement its first legal form in his Novella 131, and the Council in Trullo (692) confirmed it with a ranking of Rome, Constantinople, Alexandria, Antioch and Jerusalem. Other sources date the collective recognition to the Council of Chalcedon in 451. The order was not fixed everywhere: one medieval Greek text, the Limits of the Five Patriarchates, places Jerusalem first while keeping the other four in their usual sequence. Rome retained the honorary first place, although in the sixth century Constantinople was regarded by many Eastern Christians as the leading see. Justinian's system also excluded churches beyond the imperial frontiers, such as the Church of the East, and recognized only the Chalcedonian incumbents at Alexandria and Antioch.\n\nThe first seven ecumenical councils\n\nThe Eastern Orthodox churches accept only the seven ecumenical councils from Nicaea I to Nicaea II as genuinely ecumenical, whereas Roman Catholics count twenty-one. The Oriental Orthodox churches, by contrast, keep only the first three councils.\n\n- Nicaea I (325) met against Arius. It affirmed the full divinity of Christ and produced the Nicene Creed.\n- Constantinople I (381) defined the divinity of the Holy Spirit and expanded the creed accordingly.\n- Ephesus (431) condemned Nestorianism and stressed the unity of Christ's divine and human natures.\n- Chalcedon (451) declared that Christ has two distinct natures, divine and human, united in one person.\n- Constantinople II (553) and Constantinople III (680–681) dealt with the Christological controversies that followed Chalcedon. The third council taught that Christ, fully divine and fully human, has two wills.\n- Nicaea II (787) restored the veneration of icons. It distinguished veneration from adoration, which is reserved for God. Papal legates attended and the pope confirmed its decrees. Earlier, the iconoclast Council of Hieria (754) had described itself as the seventh ecumenical council and banned icons. Nicaea II overturned it.\n\nEarly disputes and the churches that separated\n\nArianism, which denied the full divinity of the Son, was the first major controversy the councils addressed. Nestorianism, associated with Nestorius and rejected at Ephesus, led to a gradual distancing between the Church of the East in the Sasanian Empire and the state church of the Roman Empire from the fifth century onward. The Church of the East remains outside the communion of the other ancient churches.\n\nMonophysitism, which in the fourth to sixth centuries taught that Christ's nature is entirely divine, was rejected by Chalcedon. The schism that followed centred on Dioscorus, Patriarch of Alexandria, who would accept only the formula \"of two natures\" rather than \"in two natures.\" Those who rejected Chalcedon regarded its formula as tantamount to Nestorianism, and they advanced a Miaphysite formula stressing the unity of the Incarnation. The Oriental Orthodox churches have been separated from the rest of the church since 451. They reject the label \"Monophysite,\" which they associate with Eutyches, and prefer \"non-Chalcedonian\" or \"Miaphysite.\"" }, { "heading": "The Byzantine foundations", "text": "The Byzantine Empire gave the relationship between Church and state its most influential form. Justinian I, who ruled from 527 to 565, is the central figure. In his Novella 6 of 535 he presented the priesthood and imperial power as two gifts of God, distinct but interdependent: the emperor managed temporal affairs, while the Church safeguarded the truths of salvation. The emperor was charged with governing temporal affairs while the Church safeguarded the eternal truths of salvation. Neither was to dominate the other; instead, they were to work together in harmony for the good of the people. Later writers called this arrangement symphonia, a Greek term for accord, in which church and state complement each other without either presuming to dominate. In legal practice the boundary was less clean. Ecclesiastical and civil law were treated as indivisible, so that canon law came to be enforced by the emperor. Imperial ritual reflected the same partnership: the coronation of an emperor took place in the Church, with the patriarch presiding. The ideal was not always symmetrical. One historian notes that symphonia was an ideal for the Church but was not for the emperor, for whom the texts seem to imply that any form of equilibrium was a generous concession. Orthodox theologians have debated the model ever since; John Meyendorff, for example, read the harmony as the internal unity of a single society rather than a balance between two bodies.\n\nThe Iconoclastic controversy tested this partnership most severely. The controversy was instigated by the Byzantine Emperor Leo III in 726, when he ordered the removal of the image of Christ above the Chalke Gate of the imperial palace in Constantinople. A wider prohibition of icons followed in 730. Historians divide the dispute into two phases: the first, c. 726–787, began under Emperor Leo III and ended at the Second Council of Nicaea. The second, 815–843, began under Leo V and ended with the Triumph of Orthodoxy. The causes remain debated. Some sources interpreted the troubles as divine punishment for idolatry, expressed through Arab attacks and natural disasters, while more recent scholarship has questioned whether the traditional account of widespread destruction is well supported, suggesting that defenders of images may have exaggerated the offences for rhetorical effect. The main theological defender of images was John of Damascus, who argued that Christ coming in the flesh as the image of the invisible God changed everything. Writing from territory under Muslim rule and beyond imperial reach, he drew on Platonic ideas of images participating in their prototypes, and he held that an icon imitates its model without sharing its essence. The Second Council of Nicaea, convened by Empress Irene, negated the Iconoclast council held in Hieria in 754 and affirmed the use of religious images. The controversy resumed in the early ninth century, and the iconophile cause was carried by figures such as Saint Theodore of Studium (759-826). The dispute had political costs as well: it cost a patriarch his throne, sent monks to prison and to death, widened the gap between Constantinople and Rome, and produced the theory of the icon that Orthodox Christians still use. In 843 Theodora and Theoktistos installed the iconophile patriarch Methodios I and once again affirmed religious images, definitively ending Byzantine Iconoclasm. The Church called this restoration the \"Triumph of Orthodoxy\", and it is commemorated annually on the first Sunday of Lent in the Eastern Orthodox Church to this day. The commemoration's liturgical text also pronounces anathemas on those who attack the icons or reject the seven ecumenical councils.\n\nThe period also shaped the forms of Orthodox religious life that outlasted the empire. The Divine Liturgy, in the Constantinopolitan forms associated with John Chrysostom and Basil the Great, became the normative pattern for the Eastern churches. Hymnography flourished in the capital, and monasteries, particularly the Studite community in Constantinople, became centres of liturgical reform, copying and discipline. Byzantine scholars preserved and copied Greek classical and patristic texts, a labour that later made possible much of the Renaissance rediscovery of Greek learning. Church building and painting followed the same logic: the icon, the mosaic and the domed church were visible expressions of a theology in which the material world could bear the sacred.\n\nConstantinople's ecclesiastical prestige grew out of its political importance. The First Council of Constantinople in 381, convened under Theodosius I, was attended by 150 bishops, and there were none from Egypt, only half of them from Thrace and Asia. Its third canon gave the city's bishop the prerogative of honour after the Bishop of Rome; because Constantinople is New Rome. This reasoning displaced the older hierarchy of Antioch and Alexandria, and it provoked tension with Rome, which based its supremacy on the succession of Saint Peter rather than on the political status of a city. From this time, 381, the Bishop of Constantinople appears uniformly as first bishop of the East. That primacy of honour, rooted in the imperial capital, became the basis of the Ecumenical Patriarchate's later role within the Orthodox world." }, { "heading": "The Great Schism of 1054", "text": "Disputes before 1054\n\nThe rupture between Rome and Constantinople grew out of a long series of disagreements over authority, liturgy and doctrine. The most consequential doctrinal issue was the filioque clause, meaning \"and the Son,\" which describes the Holy Spirit as proceeding from both the Father and the Son. The phrase first entered Western creeds in local Spanish councils in the late sixth century. Charlemagne then pressed for its use in the Frankish realm, and Pope Leo III, who accepted the teaching but opposed changing an ecumenical creed, had the original text displayed in Rome. Rome adopted the clause into its liturgy only around 1014. Eastern churches objected that the Nicene-Constantinopolitan Creed could not be altered except by an ecumenical council, and that the West had acted on its own authority. Patriarch Photius denounced the addition in 867, and the question stayed open until the eleventh century.\n\nPapal claims to primacy were a second source of conflict. Eastern churches accepted Rome's honour as the first see but did not accept that the pope held universal jurisdiction over the whole Church. Reforming popes in the eleventh century, such as Leo IX, pressed these claims more forcefully, while Patriarch Michael Cerularius of Constantinople defended the autonomy of his see. Practical differences, such as the Latin use of unleavened bread in the Eucharist, added to the friction.\n\nThe events of 1054\n\nIn 1052 Cerularius closed the Latin churches in Constantinople in retaliation for Norman pressure on Greek communities in southern Italy. In 1054 Leo IX sent Cardinal Humbert of Silva Candida to the imperial capital, partly to seek an alliance against the Normans. The talks went badly, and Leo died in April 1054 while the legation was still in progress, which many later historians regarded as weakening the legates' authority. On 16 July 1054 Humbert placed a bull of excommunication against Cerularius on the altar of Hagia Sophia and then left the city. A synod in Constantinople on 20 July condemned the legates in turn. Cerularius's synod named only Humbert and two colleagues, together with their followers, and did not formally excommunicate the Latin Church as a whole.\n\nFor this reason the mutual excommunications of 1054 are conventionally taken as the moment of division, yet their immediate scope was limited. Historians have debated whether 1054 should be read as a decisive break or as an episode within a longer process. Many scholars stress that the two sides continued to recognise each other as churches for decades, and that the divide deepened gradually through the twelfth century and especially after the Fourth Crusade of 1204. Others argue that the events were politically and personally charged and that their later symbolic weight exceeded their institutional effect at the time.\n\nAttempts at reunion\n\nSuccessive Byzantine emperors sought union with Rome mainly to secure Western military help against the Turks and other enemies. The Second Council of Lyons, convened by Pope Gregory X in 1274, was the first major attempt. Emperor Michael VIII Palaiologos accepted papal supremacy and the Latin formula on the filioque, and the Greek delegates signed in Lyons. The agreement met strong resistance from the Byzantine clergy and population, and the union was not implemented effectively. After Michael's death in 1282, the Byzantine church repudiated it.\n\nThe Council of Ferrara–Florence (1438–1439) was the most serious effort. Its negotiations followed years of diplomacy, and the Greek side insisted that only a council held in the East could bind the Church. The union decree was signed in 1439, but the Byzantine patriarch Joseph died during the council, and the agreement was broadly rejected when the delegates returned home. Some Eastern churches did not sign at all, and the Serbian church declined to take part. Monastic and popular opposition was strong, and the anti-unionist Mark of Ephesus became a symbol of resistance. The 1484 Synod of Constantinople condemned the Council of Florence, and the union has never been accepted by the Eastern churches. Reunion failed because the Byzantine elites needed Western help but could not persuade their own clergy and people to accept papal supremacy. The memory of the Fourth Crusade and the Latin conquest of Constantinople in 1204 made the proposal especially painful, and the papal side did not offer the concessions that Eastern leaders demanded.\n\nLong-term consequences\n\nThe schism reshaped the political landscape of the eastern Mediterranean. The sack of Constantinople in 1204 by Crusaders created a Latin Empire that lasted until 1261 and left lasting resentment in Byzantium. Western powers' conduct in the Balkans and the Levant, combined with rivalry over trade and territory, made the Byzantine state dependent on Venetian and Genoese interests and weakened its defences before the Ottoman advance, which ended with the fall of Constantinople in 1453. In the Orthodox world, the Latin West came to be seen as a source of doctrinal error and political danger, and this perception shaped identity in the Greek, Slavic and later national churches.\n\nCulturally and theologically, the two communions developed in separate directions. Western scholastic theology and Eastern patristic and mystical theology, with their different approaches to the Trinity, grace and the vision of God, increasingly served as markers of distinct traditions. The filioque remained a central point of dispute, and both churches developed their own accounts of the Church's authority, the papacy and the councils. Efforts at union continued in later centuries, but they were repeatedly disrupted by political rivalry and by mutual suspicion, and the division remains one of the defining features of Christian history." }, { "heading": "Expansion among the Slavs and the Rus' conversion", "text": "Cyril, Methodius and the Slavonic liturgy\n\nThe mission to the Slavs began with two brothers from Thessalonica. In 863 they went to Great Moravia at the invitation of Prince Rastislav, who wanted to replace German clergy with missionaries of his own choosing, partly to safeguard his realm's political independence from its Germanic neighbours. Prince Rastislav of Great Moravia invited the two brothers to preach Christianity in his domains. This request was a fallout of the efforts of the Slavic princes in central Europe attempting to maintain their independence from their Germanic neighbors.\n\nTheir central innovation was linguistic. Cyril devised the Glagolitic alphabet so that Greek liturgical texts could be rendered into what is now called Old Church Slavonic, and the brothers were convinced that Christianity should be presented to people in their own tongue, as was the practice in the East. It is generally agreed that it was created in the 9th century for the purpose of translating Greek liturgical texts into Old Church Slavonic by Cyril, a Christian monk from Thessalonica. The language was based on the dialect the brothers knew from their home city. The Glagolitic script was probably invented by Cyril himself and the language he used for his translations of religious texts and his original literary creation was based on the Eastern South Slavic dialect he and his brother Methodius knew from their native Thessaloniki.\n\nOpposition came from the Frankish clergy, who held that only Latin, Greek and Hebrew were fit for worship. The Frankish clergy in Moravia fiercely opposed the use of Slavonic. They held to a trilinguist theory, maintaining that only Latin, Greek, and Hebrew were acceptable for use in worship. After the brothers appealed to Rome, Pope Adrian II gave formal approval to the Slavonic liturgy, and Methodius was made archbishop for the region. After Methodius's death, his disciples were expelled from Moravia and found refuge in the First Bulgarian Empire. After the deaths of Cyril and Methodius, their disciples were expelled from Moravia, and they moved to the First Bulgarian Empire instead. There the Cyrillic alphabet gradually replaced Glagolitic, a shift that Glagolitic was subsequently replaced by the Cyrillic alphabet created in the First Bulgarian Empire. Both brothers are venerated in Orthodoxy as saints with the title \"Equals to the Apostles.\" Church Slavonic thus became the template for liturgical writing across Orthodox Slavdom.\n\nKievan Rus' and the baptism of 988\n\nThe Christianization of the eastern Slavs was a later and more consequential step. Christian presence in Kiev predated Vladimir: Igor's widow, Grand Princess Olga, grandmother to Vladimir, was even baptized a Christian in the Byzantine capital ten years later, although the pagan faith remained the religion of her Kievan state. The decisive act came under Vladimir. According to the Primary Chronicle, the mass baptism of the residents of Kiev in 988 as Grand Prince Vladimir accepted Orthodox Christianity as the religion of his lands. Byzantine sources describe a political bargain: Vladimir supplied troops to help Emperor Basil II suppress a revolt, and in return he was baptized as Basil and married Basil's sister Anna. Emperor Basil II in Constantinople approached Vladimir for aid suppressing a revolt of some of his generals. In response, Vladimir sent troops to help Basil put down the revolt. As part of their earlier agreement, Vladimir was baptized with the Christian name Basil, and followed his baptism by a marriage to Basil II's sister, Anna Porphyrogenta.\n\nVladimir then ordered the population of Kiev into the Dnieper, where priests performed the rite. First, Vladimir's twelve sons and many boyars were baptized. Then, the next day all the residents of Kiev were called to the river, where the Orthodox priests completed the sacrament of baptism. The conversion brought a whole cultural package. It meant the adoption of an entire culture, replete with the artistic tradition of icon painting, Byzantine style architecture, monasticism, religious education, legal principles, and other patterns of thought. Rus' became part of the Byzantine ecclesiastical sphere, and the Russian Church's history begins with the Christianization of Kievan Rus', which commenced in 988 with the baptism of Vladimir the Great and his subjects by the clergy of the Ecumenical Patriarch of Constantinople.\n\nMoscow and the \"Third Rome\"\n\nAfter the fall of Constantinople in 1453, the centre of gravity of Orthodox Russia moved north. Starting in the 14th century, Moscow served as the primary residence of the Russian metropolitan. The ideological justification for this shift came from the monk Philotheus of Pskov. The idea emerged in the late 15th and early 16th centuries after the Fall of Constantinople, receiving its classic formulation in the epistles of the monk Philotheus of Pskov, who stated that \"two Romes have fallen, the third stands, and a fourth there shall not be.\" In his letters, Philotheus cast the first Rome as having fallen through heresy and the second Rome, Constantinople, as having fallen through sin. The third Rome, Moscow, was standing. His letter to Grand Duke Basil III came in 1511, shortly after Pskov was annexed by Moscow. Originally the doctrine was eschatological, and its political reading grew later. In 1593 the Russian Church received approval of its new status as a patriarchate from the patriarchs of Jerusalem, Alexandria, and Antioch. The Russians accepted their new patriarchate being placed fifth in honor after the four ancient Orthodox patriarchates.\n\nBalkan, Romanian and Caucasian missions\n\nBeyond Rus', Orthodoxy spread through Byzantine and Slavic channels in the Balkans and beyond. Bulgaria became the principal recipient of the Moravian disciples' work, and its literary schools, centred on Preslav and Ohrid, produced much of the early Slavonic writing. Serbia developed its own church through monastic foundations such as Hilandar on Mount Athos, and secured ecclesiastical independence in the early thirteenth century through Saint Sava. Romanian lands, which had Slavic and Byzantine influence, acquired their own metropolitan sees in Wallachia and Moldavia in the fourteenth and fifteenth centuries, and the principalities later became centres of Orthodox church building and manuscript production. In the Caucasus, the Georgian church traces its origins to the fourth century and developed a distinctive literary and monastic culture. Across these regions, monasteries functioned as schools and copying centres, so that the spread of Orthodoxy went hand in hand with the spread of literacy in vernacular languages." }, { "heading": "Ottoman rule and the Orthodox in the Balkans and Greece", "text": "The fall of Constantinople and the surviving patriarchate\n\nThe conquest of Constantinople in 1453 did not end the institutional life of Orthodoxy. In January 1454 the sultan Mehmed II, who had conquered Constantinople in 1453, allowed the election of a new patriarch, who was to become millet-bachi, the head of the entire Christian millet, or in Greek the \"ethnarch\". The Ecumenical Patriarchate thus survived as an institution, but its position changed. The patriarch of Constantinople saw his formal rights and jurisdiction extended both geographically and substantially, and his power ceased to be purely canonical and spiritual and became political as well. Historians have also questioned how fully formed the arrangement was at the start. Benjamin Braude debunked the early origins of the millet system, and later scholarship treats the 1450s settlement as a process rather than a single decree.\n\nThe millet system and the patriarch as intermediary\n\nUnder Ottoman law, religious affiliation rather than language defined the community. Because Islamic law makes no distinction between nationality and religion, all Christians, regardless of their language or nationality, were considered a single Rum Millet. The patriarch was therefore answerable to the Ottoman administration for the whole Orthodox population, responsible to the Ottoman administration for all matters concerning the Orthodox religious community. In practice, all Orthodox Churches within Ottoman territory were under the control of Constantinople. The patriarch also acted as a fiscal intermediary: he collected and allocated the poll tax and served as his community's temporal leader.\n\nThis arrangement gave Orthodox communities a degree of internal autonomy while placing them in a subordinate position. Christians were not equal under Ottoman rule, and any Christian mission or proselytism among the Muslims was considered a capital crime. The patriarchate's authority over other Orthodox peoples also created friction. Before the conquest, the Slavic-speaking Orthodox had been organised in separate patriarchates at Ohrid, Trnovo and Ipek, and by the time of Ottoman conquest, the Slavonic branch in the Sultan's dominion had split into three patriarchates. Later the Ottomans suppressed the archbishopric of Ohrid, and subordinated its Bulgarian Orthodox people to the Ecumenical Patriarchate in 1767.\n\nNationalism and the emergence of autocephalous churches\n\nFrom the early nineteenth century, national movements challenged the patriarchate's authority. In SEE, the authority of the Ecumenical Patriarchate fragmented because of rising national movements. The new states of the region tended to create national churches, and the local states fostered the creation of autocephalous national churches (Greece in 1833, Serbia in 1878, and Bulgaria in 1878).\n\nThe paths differed considerably. The Greek church was declared autocephalous unilaterally, and the unilateral declaration of autocephaly caused a protracted crisis between Greece and the Patriarchate in Istanbul, which objected to unilateralism as a severe violation of the procedures stipulated by Orthodox canon law. Serbia moved more gradually. When their principality became a vassal state of the Ottoman sultan (1830), the Serbs persuaded the Patriarchate of Constantinople to grant autonomy to the Metropolinate of Belgrade (1831). They later used the newly achieved political sovereignty of Serbia in 1878 to secure the grant of autocephaly to the Serbian Orthodox Church in 1879. Romania's church also declared independence in 1865, and the Bulgarian Exarchate recognized by the Ottomans in 1870 was the answer to the unilateral declaration of an autocephalous Orthodox Church of Greece in 1833 and of Romania's in 1865. The Bulgarian case proved the most bitter. Constantinople reacted strongly and declared the Bulgarian church schismatic in 1872. It took 75 years until the Patriarchate in Istanbul recognized Bulgarian autocephaly in 1945.\n\nThe Greek War of Independence and the execution of Gregory V\n\nThe Church was directly drawn into the Greek War of Independence. The uprising began in 1821 when Alexandros Ypsilantis crossed the Prut river and marched into Moldavia. The Ottoman government held the patriarchate responsible. As Ethnarch of the Orthodox millet, Gregory V was blamed by Ottoman Sultan Mahmud II for his inability to suppress the Greek uprising. Gregory had in fact condemned the revolutionary activity, in order to protect the Greeks of Constantinople from such reprisals by the Ottoman Turks. The reprisals came anyway. Directly after celebrating the solemn Easter Liturgy, Gregory V was accosted by the Ottomans and, still in full liturgical vestments, was taken out of the Patriarchal Cathedral. He was hanged at the gate of the Patriarchate, and the dates given vary between Orthodox and Western sources because of the calendars used: the execution is recorded as 10 April (Julian) in some accounts and as 22 April (Gregorian) in others. The massacre that followed took the lives of around 10,000 Greek civilians. The Church of Greece later honoured him: in 1921, the Church of Greece canonized Patriarch Gregory as a saint." }, { "heading": "Doctrine of God, the Trinity and salvation", "text": "Eastern Orthodox teaching about God rests on the fourth-century settlement of the Trinitarian controversy, which the Cappadocian Fathers (Basil of Caesarea, Gregory of Nyssa and Gregory of Nazianzus) brought to a stable form. Their formula, one ousia (essence) in three hypostaseis (persons), protected both the unity of God and the full divinity of the Father, Son and Holy Spirit. Historians note that the phrase itself is rare in the Cappadocians' own writings, and that the distinction between the two terms was only worked out in the late fourth century and did not convince everyone at the time. Basil explained the relation by analogy with shared humanity: individual persons each share a common nature while being distinct from one another. The arrangement became binding through the First Council of Constantinople in 381. In Orthodox theology the Trinity is therefore not a set of three divine \"parts\" but three distinct persons who fully possess one divine nature, a point that later underlies the critique of the filioque clause.\n\nThe most distinctive Orthodox refinement of this doctrine is the distinction between God's essence and his energies, formulated by Gregory Palamas (1296–1359). Palamas defended the hesychast monks of Mount Athos against the charges of the humanist Barlaam of Calabria. His aim was to preserve both God's absolute transcendence and his real presence in creation: the essence is beyond all participation, while the uncreated energies are the means by which God truly communicates himself. Palamas claimed to be following the Cappadocians, and in particular Basil's statement that \"we know our God from His energies\" but cannot approach his essence. Palamas held that the essence is eternal and unoriginate, whereas some energies, those directed toward created things, have a beginning in time because creation does. The Palamite teaching was endorsed by a Constantinopolitan council in 1351, and it became the normative position in the Orthodox East.\n\nThe doctrine has been contested both inside and outside Orthodoxy. Western scholastic theology, with its claim that God is pure act and absolutely simple, has been criticised by Orthodox theologians as incompatible with a real distinction between essence and energies. Some modern interpreters have argued that Palamas did not intend an ontologically separate distinction at all, and that later polemical followers overstated his position. Within the Orthodox tradition, however, the essence-energies distinction is widely regarded as the framework that makes the mystical experience of the hesychasts intelligible as a real encounter with God.\n\nTheosis, or deification, is the goal that these doctrines serve. Athanasius of Alexandria formulated it in the fourth century by linking the Incarnation to human salvation, and he argued that only a Saviour who was truly God could bring humanity into communion with the Trinity. Maximus the Confessor (580–662) made deification the central theme of his whole system, treating it as the supreme end of the human will. For Maximus, deification is not a natural human potential but a gift of grace that requires human cooperation. Nature cannot grasp God, so the transformation depends wholly on God's mercy. Maximus described it as a change in the mode of human existence rather than the replacement of human nature itself. He also set out three stages of spiritual progress (ascetic practice, natural contemplation and theology), and he linked the process to the sacramental life of the Church, beginning with baptism.\n\nApophatic (negative) theology sets the limits of how this God can be spoken of. Drawing on the Alexandrian and Cappadocian tradition and on the writings attributed to Pseudo-Dionysius the Areopagite, Orthodox theology holds that the divine essence is known only by what it is not, while affirmative (cataphatic) statements describe God only through his acts and names. This does not mean that God is unknown, but that human concepts always fall short of him. Its methodological consequence is that theology is understood less as a system of definitions than as a form of contemplation (theoria) pursued through purification, prayer and liturgy. The essence-energies distinction gives this negative approach a positive counterpart: the believer can truly participate in God's energies while never comprehending his essence, which is why the apophatic and the mystical strands of Orthodox thought are typically held together." }, { "heading": "Scripture, Holy Tradition and conciliar authority", "text": "Orthodox theology does not treat Scripture as a self-sufficient source of doctrine. Holy Tradition, of which Holy Scripture is a part, includes the writings, teachings, and acts of the apostles, saints, martyrs, and fathers of the Church, the liturgical and sacramental traditions, the oral tradition of the early Church, and the decisions of the Ecumenical Councils. Within this framework, some Orthodox writers describe three witnesses to truth: the consensus of the Holy Fathers, the ongoing guidance of the Holy Spirit through the nous or mind of the Church, and the praxis of the Church, including asceticism, liturgy, hymnography and iconography. The Fathers are not regarded as individually infallible. Authority rests in the patristic consensus, meaning the agreement of the Fathers across different eras on essential teachings. Where Fathers differ on matters that are not essential, Orthodox theologians separate binding doctrine from personal opinion, which they call theologoumena.\n\nThe Orthodox view of Scripture is that the Bible emerged from the life of the Church and is read within it. Eastern Orthodoxy treats Scripture as a subset of Holy Tradition, namely the most important part of the teaching handed to the Apostles and then written down, so it must be interpreted within Tradition and cannot be separated from it. Orthodox authors generally reject verbal dictation. One widely cited formulation calls the Bible a record of truth and not truth itself, which leaves room for other records of the experience of God, such as the writings of the Fathers, the liturgical texts and the decisions of the councils. Within Scripture itself, the four canonical Gospels receive special reverence above the epistles and other texts.\n\nThe Orthodox Old Testament is based on the Septuagint, the ancient Greek translation of the Hebrew Scriptures. It is the basis of the canonical Old Testament of the Orthodox Church. Orthodox sources argue that when the Apostles quoted the Old Testament in the New Testament, they were usually quoting this Greek version. As a result, the Orthodox canon is larger than the Hebrew canon: the Eastern Orthodox and Oriental Orthodox Churches include up to 49 Old Testament books, compared with 46 in the Catholic canon and typically 39 in Protestant Bibles. The Orthodox prefer the term anagignoskomena, meaning \"things that are read\", to the Western term deuterocanonical. The status of these books was formally affirmed at the Synod of Jerusalem in 1672, which, by Orthodox accounts, stated explicitly what was already the long-standing unwritten tradition of the Orthodox Church regarding them. Some Orthodox apologists hold that the canon came about through liturgical use and the Fathers' acceptance rather than through a single decree, which shows how Orthodox thinkers tie canonicity to the life of the Church rather than to formal legislation alone.\n\nThe Russian term sobor, meaning both council and church building, underlies the concept of sobornost. The concept of sobornost, which means both catholicity and conciliarity, became a dominant theme in the rethinking of Orthodox ecclesiology. In this model, authority is collective rather than located in a single person. Historically, the conciliar structure began with the bishop acting together with the presbyters in the earliest local churches, and when parishes were created, the presbyters in charge represented the experience and views of the laity to the bishop. Orthodox ecclesiology in this sense stands in contrast to the Roman doctrine of personal supreme power exercised by the pope.\n\nThe status of ecumenical councils is a further point of difference. Orthodoxy is known as the \"Church of the Seven Councils,\" and it looks to the ecumenical councils for authoritative teaching that guides the church even today. A council, however, is authoritative only in so far as it is received. A council is not authoritative in and of itself, but only as it is received. Reception is understood as something lived rather than formally declared. Critics within the tradition note the difficulty of this principle: Chalcedon was not received by the whole church, which raises the question of who validates a council. Some theologians warn that overemphasis on reception could democratize the conciliar principle by requiring councils to be ratified in a juridical process. Pan-Orthodox councils, which have no binding power over an autocephalous church without its consent, face similar questions of legitimacy; the Holy and Great Council held on Crete in 2016 was the first gathering of its kind in more than a millennium, and several churches, including Russia, Georgia and Bulgaria, did not take part. Lay participation has also been a recurring theme. At the Moscow Council of 1917–18, 564 delegates took part, the majority of them elected and over half of them laypeople." }, { "heading": "Sacraments and the Divine Liturgy", "text": "The Holy Mysteries\n\nThe Orthodox Church usually calls its sacraments the \"holy mysteries\" (Greek mysteria), a term that reflects its emphasis on the hidden presence of God in visible rites. Contemporary Orthodox catechisms and textbooks generally name seven: baptism, chrismation, Communion, holy orders, penance, anointing of the sick, and marriage. The count itself is a later habit. The practice of enumerating the sacraments was taken over from Roman Catholic usage, and the older Orthodox approach treats much of the Church's life as sacramental. The Orthodox Church does not formally cap the number, and the Euchologion, the prayer book that contains the rites, does not fix one either.\n\nBaptism is normally followed at once by chrismation, the anointing with myron (chrism) that the bishop consecrates. The Orthodox treat it as the gift of the Holy Spirit that completes baptism, and by admitting children immediately after their baptism to both chrismation and Communion, the Eastern Christian tradition maintains the meaning of baptism as the beginning of a new life nourished by the Eucharist. Penance, or confession, is conducted before a priest and is understood as the restoration of communion with God after sin. Marriage, ordination and the anointing of the sick each have their own service books. Confession is also tied to Communion: Communion is given only to baptized, chrismated Orthodox Christians who have prepared by fasting, prayer, and confession.\n\nInfant communion and the Divine Liturgy\n\nEastern Christianity differs from the Western practice in one notable way. Communion is given at the Divine Liturgy to all baptized and chrismated church members regardless of age, so infants receive the Eucharist in the same service as their baptism. Communion is administered in both kinds: the priest typically places the consecrated bread and wine together on a spoon and gives them to the communicant. The priest will administer the Gifts with a spoon directly into the recipient's mouth from the chalice. Some Orthodox writers have questioned whether frequent reception is spiritually sound, and practice varies between parishes and between Greek, Slavic and other traditions.\n\nThe Eucharist is celebrated in the Divine Liturgy, which is used in two principal forms. The Liturgy of St John Chrysostom is the eucharistic liturgy most generally used in Orthodox worship, and the Liturgy of St Basil the Great is used on a smaller number of occasions, including several Sundays of Great Lent and the feast of St Basil on 1 January. Both share the same overall shape. The Liturgy of Preparation comes first, followed by the Liturgy of the Catechumens, which contains the scripture readings and sermon, and then the Liturgy of the Faithful, which culminates in the eucharistic prayer (anaphora) and communion. In modern times, this restriction applies only to reception of the sacrament of holy communion. The words of institution and the epiclesis, the prayer asking the Spirit to change the gifts, are central to the anaphora in both forms.\n\nThe iconostasis and the sacred space\n\nThe church building is organized around a screen that structures the liturgy. The sanctuary and nave are separated by the iconostasis. The iconostasis is usually high and richly decorated with images or icons of Our Lord, Our Lady, and various saints, and set facing the nave. It typically has three doors: the central Royal Doors, through which the clergy move during the Eucharist, and two side doors. Icons are arranged in tiers, and in the traditional Russian pattern there may be four or more. The screen makes the altar visible to the congregation while keeping the most sacred actions partly hidden, a balance that reflects the mystery theology described above. Liturgical chant, censing and the procession of the Gifts all take place within this framework.\n\nThe liturgical calendar\n\nThe Orthodox year is built around Pascha, the feast of the Resurrection, which is the greatest of the feasts of the Orthodox Church. Its date is fixed by a computus rather than the solar calendar: Pascha falls on different calendar dates from year to year, calculated according to a strict set of rules. The date of Pascha determines the movable feasts and the fasting seasons. Pascha is set apart from the festal cycle and is not counted among the thirteen feasts above all the rest, which are Pascha together with the Twelve Great Feasts. Of these twelve, eight honour Christ and four honour the Theotokos, the Mother of God. Some fall on fixed dates, such as the Nativity of Christ, Theophany and the Dormition of the Theotokos, while others, including Palm Sunday, the Ascension and Pentecost, depend on Pascha.\n\nThe fasting cycle is equally structured. The Great Lent before Pascha is the longest and most demanding of the fasts, and the Orthodox also observe the Nativity Fast before Christmas, the Apostles' Fast, and the Dormition Fast in August. For 50 days, we refrain from all fasting, and stand instead of kneel at all services, in commemoration of our Lord's Resurrection. Churches that use the revised calendar and those that retain the Julian calendar celebrate the fixed feasts on different days, which is one reason lists of feast dates vary between jurisdictions." }, { "heading": "Icons, sacred art and architecture", "text": "The theology of the icon\n\nIcons hold a central place in Orthodox devotion, and their legitimacy rests on a formal doctrinal decision. Called together by Empress Irene, the Seventh Ecumenical Council met at Nicaea in the autumn of 787 under Patriarch Tarasios and gave icon veneration official approval, a position Orthodox churches have not revised since the veneration of icons obtained official approval at the Seventh Ecumenical Council, the Second Council of Nicaea (A.D. 787); the Orthodox position on icons has remained unchanged since then. The council was also cautious in its wording, treating icons as a consequence of the Incarnation rather than as an independent religious object.\n\nThe doctrinal basis is the Incarnation. Because God took on human nature and became visible, Orthodox writers argue that he can be depicted. Worship is reserved for God, whereas veneration is distinct from worship, and honour may be directed to the Mother of God and the saints. Their images are not venerated for their material; we do not venerate the matter (wood or stone), but only the person represented on them. Believers often describe icons as windows into the spiritual realm, assisting believers in contemplation and prayer, and the church teaches that they form a point where heaven and earth meet and that taken together they form an image of God's Kingdom.\n\nCanon, iconoclasm and Rublev\n\nThe controversy over images in the eighth and ninth centuries shaped the later canon. Leo III the Isaurian proscribed icons as idolatrous, and the restoration of their use is commemorated in the ceremony celebrating their restoration is known as the Triumph of Orthodoxy. Icon painting follows fixed visual conventions, usually executed in tempera on wooden panels, and it is valued for its adherence to inherited types rather than for naturalistic individuality.\n\nThe most celebrated example is Andrei Rublev's Trinity. It reworks the Genesis 18 scene of Abraham's hospitality, and Rublev removed the figures of Abraham and Sarah from the scene, and through a subtle use of composition and symbolism changed the subject to focus on the Mystery of the Trinity. It was devised as a tribute to the monastery's founder, the Trinity Lavra near Moscow, and its date remains disputed, with the official version stating 1411 or 1425–27. In 1551 the Stoglav Council fixed the pattern for later painters: the image of the Holy Trinity should be represented as Rublev had done and not otherwise.\n\nChurch architecture\n\nByzantine church building was dominated by the cross-in-square plan. It was the dominant form of church architecture in the middle and late Byzantine Empire. It featured a square centre with an internal structure shaped like a cross, topped by a dome. Its origins are uncertain, but one hypothesis links it to a small, unisex monastic community in Bithynia, near Constantinople, that may have developed the cross-in-square plan church during the Iconoclastic period. After Iconoclasm it became the standard type, and from the tenth century until 1453 it was the most common church plan. Most of its domes were modest in scale; the four-column support suited spans under about six metres.\n\nThe plan spread to the north and west of the empire. The octagonal-dome variant provided larger interior surfaces for mosaic decoration and eight supports for a bigger dome. In Kyiv, the eleventh-century Hagia Sophia used a cross-in-square arrangement but added five naves and thirteen domes arranged in pyramidal formation. In Serbia, the cross-in-square type later acquired a pyramidal pile-up of domes, as at Gračanica, while churches such as Studenica, Sopoćani and Dečani carried the tradition through the thirteenth and fourteenth centuries. Within these churches, the screen separating nave from sanctuary evolved into the iconostasis found in Orthodox churches today.\n\nLiturgical music\n\nLiturgical singing developed alongside the visual arts. Byzantine chant is monophonic and organised around the octoechos, the system of eight modes that structures the weekly cycle of hymns. It was written in neumatic notation, which was reformed in the early nineteenth century. In Russia, the older znamenny chant was notated in hook-shaped signs (kryuki), and from the late eighteenth century Western-influenced choral writing entered the imperial court; Dmitry Bortniansky, who directed the court chapel in St Petersburg, is the best-known figure of this period. Later Russian sacred music drew on both the Byzantine and Western traditions, which is why the Slavonic liturgical repertoire is often described as a meeting of the two." }, { "heading": "Monasticism and mystical traditions", "text": "Desert origins\n\nOrthodox spirituality grows out of the monastic movement that began among the hermits of Egypt. The Desert Fathers were early Christian hermits who practised asceticism in the Egyptian desert from the third century, and their way of life became the basis of Christian monasticism. Anthony the Great moved into the desert around 270–271 and came to be regarded as the founder of organised desert monasticism; by the time he died in 356, his biographer Athanasius of Alexandria could describe the desert as having become a city. Pachomius of the Thebaid organised communal monasteries in Upper Egypt, where monks were bound by shared prayer and labour rather than by obedience to a single elder. Their teaching survives mainly in the Apophthegmata Patrum, a collection of short, pointed sayings attributed to elders, which Byzantine and later Slavic monks read for practical guidance on humility, discernment and silence.\n\nMount Athos\n\nThe Holy Mountain, a peninsula in northern Greece, is the most important centre of Orthodox monastic life. Organised monastic life there began in 963, when Athanasius the Athonite founded the Great Laura. Today Mount Athos is home to twenty monasteries and their dependencies, and its spiritual authority has been felt across the Orthodox world for centuries. Because of the presence of Russian, Bulgarian, Serbian and other Slavic houses alongside Greek ones, the peninsula has a notably pan-Orthodox character. Women and female animals have been barred since Byzantine edicts of the eleventh century, a rule that the monasteries still observe. The community governs itself through a Holy Council in which each monastery has one representative, and an executive body, the Epistasia, whose four members rotate annually. A Greek government governor represents the Hellenic state, while the monasteries are ecclesiastically subject to the Ecumenical Patriarchate of Constantinople. The area's semi-autonomous status was affirmed by the Greek state in the twentieth century and it has been a UNESCO World Heritage Site since 1988.\n\nHesychasm and the Jesus Prayer\n\nHesychasm, from the Greek word for stillness, is a contemplative tradition in which the monk seeks inner quiet through unceasing prayer. Its central practice is the Jesus Prayer, \"Lord Jesus Christ, Son of God, have mercy on me, a sinner.\" Hesychasts read Christ's instruction to \"go into your closet\" to pray as a call to withdraw from the senses and turn inward. Some practitioners adopted specific bodily postures and controlled breathing, although these were not universal. Its definitive form took shape in the fourteenth century on Athos, though its roots lie in the earlier desert tradition, where the invocation of God's name was already emphasised. The practice became the subject of the Palamite controversy: in the 1340s and 1350s Barlaam of Calabria criticised the hesychasts, and Gregory Palamas defended them, arguing that the light they perceived in prayer was a divine energy that can be experienced without grasping God's essence. That defence later became a foundation of Orthodox doctrine.\n\nThe Philokalia and the startsy\n\nThe Philokalia (\"love of beauty\") is an anthology of Byzantine spiritual texts written between the fourth and fifteenth centuries on interior prayer, watchfulness of the heart and the purification of the passions. It was compiled in the eighteenth century by Nikodemos of the Holy Mountain and Makarios of Corinth and printed in Venice. Its authors include Evagrius Ponticus, Maximus the Confessor, Symeon the New Theologian and Gregory Palamas. Paisius Velichkovsky's Slavonic translation made it widely available in Russia and Romania, and it shaped the nineteenth-century Russian revival of the Jesus Prayer, including the popular narrative The Way of a Pilgrim. The Russian selection prepared by Theophan the Recluse placed greater emphasis on the role of the spiritual father, which helped spread the practice beyond monasteries. In Russia, the startsy, or spiritual elders, of communities such as Optina Pustyn offered direction to laypeople and monastics through personal counsel and confession, a practice that became a defining feature of modern Russian Orthodox spirituality. The English translation of the Philokalia, prepared by Palmer, Sherrard and Ware in four volumes, has since made these texts widely read in the Anglophone world." }, { "heading": "Church organization and the principle of autocephaly", "text": "Eastern Orthodoxy has no single governing centre equivalent to the papacy. It is a communion of self-governing local churches, and the principle that organizes them is autocephaly (from the Greek for \"self-headed\"). An autocephalous church elects its own primate and manages its own affairs while remaining in communion with the others. An autonomous church manages most of its internal life but still depends on a mother church for certain matters, such as the consecration of its bishops or the approval of its statutes. The Ecumenical Patriarchate counts fourteen autocephalous churches in its own reckoning, a figure that is widely used but is not accepted by every Orthodox church.\n\nThe autocephalous churches fall into two groups. The first is the ancient Pentarchy of Constantinople, Alexandria, Antioch and Jerusalem, which together with the modern patriarchates of Russia, Serbia, Romania, Bulgaria and Georgia makes up the nine historic patriarchates. The second group consists of five churches headed by an archbishop or metropolitan: Cyprus, Greece, Poland, Albania, and the Czech Lands and Slovakia. Some other churches, such as those of Finland and Estonia, hold autonomy under Constantinople, while the Ukrainian Orthodox Church and several churches in Latvia and Moldova have autonomy under Moscow. The rank of a church is therefore a combination of age, status and formal recognition, and it does not always match its size.\n\nThe Ecumenical Patriarch of Constantinople holds a primacy of honour, described as \"first among equals\". Constantinople's special standing is linked to its role as the successor of the imperial capital, which Constantine transferred from old Rome to Byzantium in 330. The Ecumenical Patriarch convenes pan-Orthodox assemblies and is the usual spokesman for Orthodoxy in dealings with other Christians. His authority is not universal jurisdiction, however: he cannot govern the synods of other churches or intervene in their internal affairs. His claim to an exclusive right to grant autocephaly is also contested. The case of the Orthodox Church in America, which Moscow declared autocephalous in 1970, shows the problem. Constantinople and most other Orthodox churches did not recognize that grant, because the Ecumenical Patriarchate holds that only it may give autocephaly.\n\nAutocephaly has traditionally been granted by a mother church through a formal act, often called a tomos, and then recognized by the other churches. The modern patriarchates of Russia, Serbia, Romania, Bulgaria and Georgia, along with the archbishoprics of Greece, Albania, Poland and the Czech Lands, were mostly founded or recognized through this procedure, with Constantinople playing the central role. Cyprus is the traditional exception: its autocephaly is said to have been confirmed by the Council of Ephesus in 431, and the Church of Cyprus remains under an archbishop who is not subject to a higher ecclesiastical authority. Recent cases show how contested the process can be. In 2019 the Ecumenical Patriarch granted autocephaly to the Orthodox Church of Ukraine, which the Patriarchate of Alexandria, the Church of Greece and Constantinople recognized, while other churches took different positions. In 2022 the Serbian Patriarchate granted autocephaly to the Macedonian Orthodox Church, a decision that was likewise recognized by some churches and not by others.\n\nThe territorial principle holds that each city and region should be served by a single bishop within one jurisdiction. In practice, national churches were formed along ethnic and political lines, especially in the Balkans and Eastern Europe, so that the church often became a marker of national identity. This produced tension in the diaspora, where parishes of different national origins in the same city may fall under different jurisdictions. Constantinople asserts direct jurisdiction over Orthodox Christians in regions not already under an autocephalous or autonomous church, a claim that other churches have disputed.\n\nChurch titles reflect this structure. A patriarch heads one of the historic or modern patriarchates, and an archbishop heads an autocephalous or autonomous church or an archdiocese. A metropolitan is a bishop of a metropolis, which is a senior see with authority over other dioceses, and in some churches the title is also honorific. Bishops are elected by synods, and the primate of an autocephalous church is elected by the synod of its bishops rather than appointed from outside. The ranking of these titles and the recognition of new churches thus depend on the agreement of the wider Orthodox communion, which is why disputes over titles and autocephaly have repeatedly been disputes over canonical order as well as over authority." }, { "heading": "The Russian Revolution, Soviet persecution and religious revival", "text": "Imperial Russia and the Council of 1917–18\n\nPeter I had abolished the patriarchate in 1721 and placed the Church under a Holy Synod run by a civil procurator, which greatly reduced ecclesiastical power and tied the Church closely to the state. The 1917–1918 Council was the first council of the Russian Church since the one of 1681–1682, and the first since Peter I deposed the Patriarch. This action resulted in a far-reaching diminution in ecclesiastical power and deep State involvement in the affairs of the Church.\n\nThe All-Russian Local Council opened in Moscow in August 1917 and was attended by 564 members, including 227 from the bishops and clergymen, 299 from the laity. Its central act was the restoration of the patriarchate. The patriarch was defined as \"first among equal bishops,\" subordinate and accountable to a national Sobor that retained supreme authority. Candidates were chosen by lot, and the name of Archbishop Tikhon was drawn, making the former primate of the American archdiocese the first patriarch since 1700. The council was convened only after the Bolsheviks had seized power, and it continued to meet despite their opposition.\n\nTikhon and the Soviet state\n\nThe Bolshevik government quickly moved against the Church. The Bolsheviks nationalized Orthodox church lands, took over all Orthodox schools and seminaries, withdrew state subsidies, and established exclusively civil marriages. In 1918 church and state were completely separated, and the church was dispossessed of its legal rights, which opened the way for local attacks on priests and widespread looting of churches. Tikhon responded with the excommunication and anathema of \"the enemies of the Church\" in January 1918, but during the civil war he declined to take sides. He died in 1925, and because the Church could not hold a council under persecution, he had left a written testament naming three successors in order of priority. The first two candidates were already in prison or exile, so the third, Metropolitan Sergius, took over. From 1927 Sergius pursued a policy of unconditional loyalty to the Soviet government, which led to significant criticism of him and the separation of some lay people and clerics. The resulting split between loyalist and anti-Sergian communities persisted for decades.\n\nAnti-religious campaigns and mass repression\n\nIn 1928 the authorities decided to \"intensify the anti-religious struggle,\" which was considered as important as the class struggle. Between 1927 and 1940, the number of Orthodox churches in the Russian Republic fell from 29,584 to fewer than 500, mostly through systematic demolition. By 1941 only a twelfth of the Russian Orthodox Church's priests were still functioning in their parishes. Theological education was also destroyed: from 1914 to 1939, all 57 Orthodox seminaries and four theological academies were suppressed. Monasteries were hit especially hard. Estimates differ, but one widely cited figure holds that the number of monasteries was reduced from 1,025 to 0 during the first decades of Soviet control, while another source puts the closures at two-thirds of the total.\n\nClergy suffered most. Estimates of the dead vary considerably, and the figures are contested. The available numbers include over 130,000 Orthodox priests arrested between 1917 and 1935, of whom 95,000 were shot, and arrests of 168,300 clergy in 1937–38, of whom at least 100,000 were shot. Some of these arrests took place during show trials, where the verdicts were a foregone conclusion, with executions happening nearly immediately after the sham trials were completed. Solovki, a former monastery, became one of the first major camps. Many believers who refused to join the official church worshipped in clandestine communities known as the Catacomb Church, which claimed to continue Orthodoxy in its true form.\n\nWartime rapprochement and the restored patriarchate\n\nAfter the German invasion of 1941, the regime changed course. Stalin decided he needed the Church's help in defending Russia and called upon Metropolitan Sergii and others to encourage patriotism among the masses. The Church donated 150 million rubles to the armed forces, collected from the faithful. The turning point came on 4 September 1943, when Stalin met Metropolitans Sergius, Aleksei and Nikolai after two decades of repression. Stalin authorized a council to elect a patriarch and the reopening of church institutions. Five days later, Sergius was \"elected\" patriarch by a mere eighteen bishops, most of whom had been in forced retirement or in labor camps. Soon after, a Council for the Affairs of the Russian Orthodox Church was established, and the Moscow Theological Academy and three colleges reopened, and monasteries and thousands of churches began to function again.\n\nThis was a bargain rather than a liberation. The church regained legal recognition and a limited institutional life, but under close state supervision and with strict limits on growth and religious education. The Soviet annexation of western territories also brought the Church millions of new faithful, and in the western Ukrainian lands the Catholic Uniate churches were integrated under the Moscow Patriarchate after all residing bishops and apostolic administrators were arrested in 1946. The relative tolerance did not last. Beginning in 1948, Stalin broke the \"truce\" and subjected the Orthodox Church to new persecutions. Under Khrushchev, a new campaign closed 12,000 churches by 1959.\n\nRevival after 1988\n\nThe late 1980s marked a turning point. The 1988 millennium of the baptism of Rus' became a public occasion for the Church, and under Mikhail Gorbachev the restrictions on religious life were eased. Over the following years, churches, monasteries and theological schools were gradually returned to Church use in Russia and in the newly independent post-Soviet states. Religious education and publishing revived, and many historic monasteries were restored. The Russian Orthodox Church thus re-entered public life, although its close relationship with the state has remained a subject of debate." }, { "heading": "Diaspora, mission and global distribution", "text": "Orthodox Christians have spread far beyond their historic heartlands through migration, missionary work and, in the twentieth century, the flight of refugees from communist and war-torn states. Parishes in North America, Western Europe and Australia were usually founded by émigrés from Russia, Greece, the Balkans, the Levant and other Orthodox lands, and they often kept the language and jurisdictional ties of their home churches. In Latin America, Orthodox communities have similarly grown out of migrant settlement. The result is a distribution in which the number of parishes outside the traditional lands is significant, but the membership remains concentrated in Eastern Europe.\n\nParallel to this, the historic patriarchates and autocephalous churches have often established several overlapping structures in the same city or country. A single territory may host parishes subordinate to the Ecumenical Patriarchate, the Moscow Patriarchate, Antioch or another see, each with its own bishops and ethnic base. This arrangement has produced long-running disputes over canonical territory, since the traditional principle of one bishop for one city is hard to apply to communities that are defined by language and origin rather than place. The Holy and Great Council held on Crete in June 2016 tried to address the problem. Its diaspora document confirmed that autonomous churches could be established outside their traditional territory only with pan-Orthodox consensus, and it kept the system of episcopal assemblies, which bring together canonical bishops in one area, as an interim measure until such time as canonical rigor can be implemented. The Council did not resolve the underlying question. Four of the fourteen autocephalous churches, including Antioch, Russia, Bulgaria and Georgia, did not attend, and the Russian Church later declined to recognize the Council as pan-Orthodox or its decisions as binding on all churches (the Bishops' Council of the ROC approved the previous resolution of the ROC Synod that stated that the ROC did not recognise the Council in Crete as Pan-Orthodox). Later jurisdictional conflicts, including those discussed in the section on the Ukrainian church dispute, grew out of the same unresolved questions.\n\nOutside Europe, the most significant growth has taken place in sub-Saharan Africa. In Kenya and Uganda, Orthodoxy spread largely through local initiative rather than through missionaries sent from abroad. One scholarly account notes that the Orthodox Church there was largely the result of people in those countries seeking Orthodoxy, rather than Orthodox missionaries from elsewhere seeking them. Some of these communities were attracted by an ideal of an African church free from colonial ties, others by the study of early Church history. The Patriarchate of Alexandria, which bears the title \"and all Africa\", received these communities and ordained local clergy, and the Church was repressed in parts of colonial East Africa in the 1950s. Russian Orthodox expansion has added a more recent and politically charged dimension: one 2026 report noted that the Russian Orthodox Church had expanded to at least 34 countries in Africa, up from four in less than three years. Pew data show the same trend in demographic terms. Sub-Saharan Africa's Orthodox population rose from an estimated 3.5 million in 1910 to 40 million in 2010, and the region now accounts for about 15% of the world's Orthodox Christians. Ethiopia's Orthodox Tewahedo Church alone has about 36 million adherents.\n\nIn East Asia, the Russian Orthodox mission to Japan is the best-documented case. Led by the priest and later bishop Nicholas Kassatkin, it began in Hakodate in 1861; the Russian imperial government established a formal mission in 1870. Kassatkin translated the main liturgical books into Japanese and built the Nikolai-do cathedral in Tokyo, and the local church grew to tens of thousands of members in the late nineteenth and early twentieth centuries. Its later history was shaped by the Russian Revolution, which caused canonical problems with Moscow, and by Japan's wartime and postwar conditions. The Orthodox Church in Japan now has a small membership, though it remains an autocephalous church and is one of the few Orthodox bodies with an indigenous, non-ethnic base in the region. Korea has a much smaller Orthodox presence, mainly among migrants and converts, and it has not produced a comparable missionary history.\n\nEstimates of total Orthodox membership vary considerably, and the differences are methodological as much as numerical. Pew's 2017 survey put the figure at approximately 260 million, and the Pew numbers do not distinguish between Eastern Orthodoxy and the non-Chalcedonian Oriental Orthodox Churches. Other counts are lower because they rely on national censuses and surveys, which often do not record denominational affiliation in detail. One independent country-by-country tally, which excluded the non-Chalcedonian churches, arrived at a mean of about 192 million. Its estimate for Russia alone was around 83 million, while Pew has reported more than 100 million. The differences reflect whether respondents identify with a church, whether they actually attend, and how a church's own claims are weighed against survey data. Ukraine is a striking example, since figures for it include all groups claiming to be Orthodox. Church-reported figures, often cited by Orthodox leaders, tend to be higher still, and figures of 200, 250 and 300 million have all circulated publicly." }, { "heading": "Jurisdictional disputes in the modern period", "text": "The 2018 break with Constantinople\n\nThe modern crisis began with the ecclesiastical status of Ukraine. On 11 October 2018 the synod of the Ecumenical Patriarchate reversed its 1686 decision that had transferred the Kyiv metropolis to Moscow, and it confirmed its intention to work toward an autocephalous church in Ukraine. The synod's decision of 11 October annulled its 1686 decision to transfer the metropolis of Kiev to the jurisdiction of the Moscow Patriarchate. Four days later the Holy Synod of the Russian Orthodox Church broke Eucharistic communion with Constantinople. Its clergy were barred from concelebrating or sharing sacraments with clergy of the Ecumenical Patriarchate, and the synod stopped commemorating the Ecumenical Patriarch during the liturgy. Moscow also set up new patriarchal exarchates in several regions as a counter-measure.\n\nConstantinople then moved to build the new body. A unification council held at St Sophia's Cathedral in December 2018 brought together the Ukrainian Orthodox Church – Kyiv Patriarchate, the Ukrainian Autocephalous Orthodox Church and two bishops from the Moscow-aligned church. The resulting Orthodox Church of Ukraine received its tomos of autocephaly from Bartholomew I in early January 2019. The Russian Church regards the grant as a politicized step that departed from canon law, and it treats the Kyiv-based church as schismatic. Its initial reaction was to define the matter as a split within the wider 2018 schism.\n\nResponses of other autocephalous churches\n\nOther churches did not respond uniformly. By January 2022, the new church had been recognized by Constantinople, Alexandria, Cyprus and Greece. Churches with close ties to Moscow, including those of Albania, Czechoslovakia, Poland and Serbia, withheld recognition. The Church of Jerusalem also declined to recognize it, partly because of the Russian Church's presence in Israel. The Church of Antioch was in a more delicate position: it wished to remain on good terms with Constantinople, yet its dependence on the Syrian government made it hard to reject the Russian Church during the civil war. The Bulgarian Orthodox Church experienced internal friction between pro-Russian and more moderate factions. Other churches, such as Georgia, were reported to be considering their position.\n\nThe recognition map also reflects a broader pattern. Non-recognition of an autocephaly is not unusual in Orthodoxy: the Orthodox Church in America is not universally recognized, yet it remains in communion with the other local churches, whereas most local churches have kept the Orthodox Church of Ukraine at arm's length. The status of the American church is also unresolved because Constantinople has never granted it autocephaly.\n\nThe 2022 invasion and church politics\n\nRussia's full-scale invasion of Ukraine in February 2022 deepened the divide. Patriarch Kirill's public support for the war placed the Moscow-aligned church in Ukraine in a difficult position. Clergy and parishes began to leave. In Amsterdam, a Russian Orthodox parish announced in March 2022 that it could no longer function within the Moscow Patriarchate. In Ukraine, more than 400 parishes had left the Ukrainian Orthodox Church – Moscow Patriarchate by late May 2022, and that month its council voted to break with the Russian Church, condemning the war and Kirill's position. Kirill, for his part, said the Ukrainian church was suffering and blamed \"spirits of malice\" for dividing the two peoples. The 2020 survey cited in these reports, which found 34% of Ukrainians identifying with the Orthodox Church of Ukraine and 14% with the Moscow-aligned church, illustrates the scale of the shift. Even so, the Moscow-aligned church still declares itself self-governing under the Russian Church, and its leadership remained listed in the Russian Church's calendar as of 2025. The Orthodox world has been affected beyond Ukraine: Bulgaria's 2024 patriarchal election, for example, was seen as reflecting divisions that the war had intensified.\n\nUnrecognized churches and canonical principles\n\nThe Kyiv Patriarchate and the Ukrainian Autocephalous Orthodox Church were regarded as schismatic by Moscow and by most other Orthodox churches before their merger. The central canonical question is who has the right to grant autocephaly. Constantinople claims that right exclusively, while Moscow appeals to the 1686 arrangement and to territorial jurisdiction. Constantinople's primacy is itself described as \"first among equals\" among the autocephalous churches, which means that its authority rests on the consent of the other churches rather than on command. Moscow has argued that autocephaly in Ukraine would legalize a division rather than heal it. The 2019 tomos has not been rescinded, and parishes continue to move from the Moscow-aligned church to the new body, so the canonical position of the Orthodox Church of Ukraine remains unsettled and disputed." }, { "heading": "Ethics, social teaching and public life", "text": "Orthodox moral teaching is grounded in Scripture, the canons and the patristic tradition, but it does not function as a single, uniformly applied code. On the indissolubility of marriage, one scholarly assessment holds that the Orthodox Churches, due to their diversity, do not have a clear cut, juridical doctrine regarding the indissolubility of marriage.\n\nOrthodox marriage doctrine treats the marital bond as very serious. Older patristic thinking described divorce as the dissolution of a \"mini-church\" formed by the spouses, not as a remedy that heals a failed union, and it classed divorce as a result of human hardness of heart. The tradition of the Church of the first centuries — which continues to have authority for the Orthodox Church — put the emphasis very strongly on two related points: divorce does not heal the diseased marriage but kills it. Within this framework, churches have used the principle of economia (oikonomia), a pastoral concession that operates alongside the strict canons. Canonical sources describe it as the temporary suspension of the strict application of church regulations without compromising dogma, and they stress that it takes place only through official church authorities and is only applicable for a particular case. This is allowed for exceptional and severe reasons, but creates no precedent. In practice, Orthodox canon law can permit a second and even a third marriage \"in economia\", but strictly forbids a fourth. Orthodox commentators also distinguish economia from the Roman Catholic notion of dispensation, which they regard as an anticipated exception with a parallel juridical norm. Procedurally, a bishop typically considers the case and may grant an ecclesiastical release from the earlier bond, while a civil divorce is usually necessary for practical reasons, but it is not the same thing as an ecclesiastical judgment. Pastoral counselling, aimed at reconciliation, is normally expected first. The practice has been a point of comparison in Catholic debates: Pope Francis, for example, remarked that the Orthodox \"follow the theology of 'oikonomia' (economy or stewardship), as they call it, and give a second possibility; they permit\" a second marriage.\n\nOn bioethics, the Russian Orthodox Church has taken the lead. Already in the year 2000, the ROC had established its social doctrine, entitled \"Basis of the Social Concept of the ROC\" (BSC). A chapter of that document addresses bioethics, and the Church frames biomedical technologies as a source of serious pastoral concern, asserting that life is a precious gift of God. The document also calls for repentance by women who have had abortions without rejecting them. Its positions are not always consistent: on reproductive technology, one reading notes that reproductive technologies are impermissible since such child conception is \"disagreeable with the design of the Creator of life,\" yet the same document allows artificial insemination and states that IVF is prohibited only if it creates an excess number of embryos. Scholars have attributed this ambiguity to the text's internal tensions, and the Church's stance on IVF and related questions has been debated publicly among believers. The document itself is not a dogmatic definition; one commentary describes it as neither an exhaustive teaching on ethics nor a dogmatic or inspired article of faith.\n\nThe same 2000 document serves as the Russian Church's general guide to its relations with the state. It is intended to guide synodal bodies, dioceses, monasteries and parishes in their dealings with secular institutions. Among the activities that clergy are to avoid, it lists political campaigning, support for particular parties and leaders, and waging civil or aggressive external war. Orthodox social thought more broadly has long been shaped by the Byzantine ideal of cooperation between church and empire, and modern churches generally reconcile loyalty to the state with claims to independence in matters of doctrine and morality.\n\nOrthodox positions on war are a particularly contested area. Historians often note that the [Eastern] Orthodox are probably most well-known for asserting that [they possess] no just war theory. Instead, rather than seek to morally elevate war and Christian participation in it so that it could be termed 'just,' the East treated it as a necessary evil. Pacifism has never been the dominant value in Russian Orthodoxy, and the ROC has nonetheless been criticized for its recent theological justifications of the invasion of Ukraine. Patriarch Kirill of Moscow, in a September 2022 sermon, described the war as an \"internecine\" conflict and prayed for its end, while also suggesting that soldiers who die in service may be granted forgiveness. The Ecumenical Patriarch Bartholomew, by contrast, called for prayer for peace and warned that the conflict could \"trigger global warfare.\" Some Balkan leaders have taken positions aligned with Moscow: the Bulgarian patriarch has, for example, aligned himself with Kirill's position on the war. He warned his clergy against \"inciting hatred\" by labeling Russia as the \"sole and unprovoked aggressor\".\n\nInternal debates have been significant. Within the Ukrainian Orthodox Church (Moscow Patriarchate), a priest's open letter asked the leaders of the world's Orthodox churches to condemn the campaign, to evaluate Kirill's statements against Scripture and tradition, and to assess the Russkii Mir doctrine, which presents Russia, Ukraine and Belarus as one spiritual community. Analysts also caution against equating the views of the whole ROC with the patriarch's statements, observing that the position of most of its clergy is determined by a compromise between loyalty to the Kremlin and commitment to the institutional interests of the church. Questions of national identity remain tied to these divisions. Even as the war continues, many parishioners are reluctant to change jurisdictions to the autonomous Orthodox Church of Ukraine." }, { "heading": "Philosophy and intellectual contributions", "text": "Orthodox thought has never been a single philosophical system. From late antiquity it borrowed the vocabulary of Platonism and Neoplatonism, but subordinated it to revelation. Gregory of Nyssa, the fourth-century Cappadocian bishop, is the standard example. He is often counted among the most prominent Christian Neoplatonists and was deeply shaped by Origen of Alexandria. Gregory of Nyssa, who lived in the second half of the fourth century CE, is one of the most prominent Christian Neoplatonists; he was heavily influenced by the Christian Middle-Neoplatonist Origen of Alexandria. Scholars disagree about how far he simply Christianized Plato. One view holds that his theology amounted to attaching Christian names to Platonic doctrines, a reading that goes too far. The opposing reading, associated with Jean Daniélou, treats his work as a transformation of Neoplatonism into a Christian mysticism centred on the soul's endless progress toward God, which Daniélou called epektasis. Gregory's theology represents a subtle transformation of Neoplatonism into authentic Christianity.\n\nHis reception of Platonic ideas was selective. He rejected emanationist monism and the notion that the world is an eternal emanation from the One, rejecting absolute monism and its emanationists' views. In his psychology the dialogue On the Soul and the Resurrection has one speaker set aside Plato's tripartite soul as unattested in Scripture, yet the text regularly builds on Plato's psychology. His analysis of ecstasy and the spiritual senses also prepared the way for Dionysius the Areopagite, Maximus the Confessor, and later Byzantine mysticism, which made him a bridge between ancient philosophy and the Byzantine contemplative tradition.\n\nPhilosophical terms in Byzantine theology were not always treated as neutral. Maximus the Confessor is a case in point: although Orthodox writers later rejected the Western filioque, Maximus defended the Filioque as a legitimate variation of the Eastern formula that the Spirit proceeds from the Father through the Son.\n\nThe critique of Western scholasticism\n\nFrom the nineteenth century onward, Orthodox thinkers presented their theology as a corrective to scholastic method. The filioque was central to this critique. Vladimir Lossky asserted that any notion of a double procession of the Holy Spirit from both the Father and the Son was incompatible with Orthodox theology, a position shared by later figures such as Dumitru Stăniloae and John Romanides. Sergius Bulgakov was a notable exception, holding that the filioque did not represent an insurmountable obstacle to reunion.\n\nBishop Kallistos Ware gave the critique its most widely quoted formulation, arguing that Latin scholasticism, by stressing the divine essence over the persons, comes near to turning God into an abstract idea. In this view the result is a God reached by metaphysical argument rather than by personal encounter. Orthodoxy, on the other hand, has been far less concerned than the Latin west to find philosophical proofs of God's existence.\n\nThe doctrine of divine simplicity was a particular point of friction. Defenders of Thomas Aquinas argue that his account is internally coherent, and they accept real and perhaps unbridgeable differences between Thomas' theology and that of the Fathers. Within the Byzantine tradition, Gennadios Scholarios, a student of Gregory Palamas, criticized Aquinas for two main errors: the filioque and the denial of the distinction between essence and energies.\n\nRussian religious philosophy\n\nRussian religious philosophy of the nineteenth and twentieth centuries grew out of Orthodox spirituality and German idealism. Vladimir Solovyov is considered to be the greatest Russian philosopher of the nineteenth century. He sought a unified system of metaphysics, ethics and theology centred on the idea of all-unity, in which reality is grounded in a metaphysical unity that embraces God, humanity, and the cosmos. His doctrine of Sophia, divine wisdom as the principle of unity in creation, became the most influential part of his legacy. Solovyov had earlier returned to his Orthodoxy after a period of disillusionment, and his thought combined mysticism with rigorous argument. He also passionately advocated an active transformation of society and adherence to the ideal of social justice, [but] resisted Marxist solutions.\n\nSolovyov's ideas shaped a generation. Solovyov's ideas informed the thinking of such prominent figures as Nikolai Berdyaev, Sergey Bulgakov, Pavel Florensky and Simeon Frank. Florensky, a priest and polymath, is associated with the Sophiological school, and his major work explores love, personhood, and religious experience. Berdyaev's work centred on freedom, eschatology, philosophy of history. Nikolay Lossky, the father of Vladimir Lossky, developed an intuitivist and personalist epistemology. Vladimir Lossky's The Mystical Theology of the Eastern Church (1944) made apophatic theology a central reference point for Western-language discussion of Orthodoxy.\n\nWider influence\n\nThe influence of this thought extended beyond theology. Florensky contributed to philosophy, theology, mathematics, physics, art theory, and linguistics, and Solovyov's ideas reached the Russian Symbolist poets, including Andrei Belyi and Alexander Blok. In modern philosophy of religion, these writers offered an alternative to both rationalist natural theology and secular positivism, and their emphasis on personhood, mystical knowledge and the unity of creation continues to be debated." }, { "heading": "Ecumenical relations and dialogue", "text": "Bilateral dialogue with the Catholic Church\n\nFormal theological dialogue between Rome and the Orthodox churches began in the late twentieth century, and its early stages were dominated by the problem of Byzantine-rite Catholic communities, which critics called \"Uniate.\" The Freising statement of 1990 rejected \"uniatism\" as a method for the search for unity because it is opposed to the common tradition of our Churches. The Joint International Commission then met at Balamand, Lebanon, in June 1993. The Orthodox side had asked that the normal sequence of the dialogue be set aside so that this question could be addressed first, and the resulting text, condemned proselytism and jurisdictional conversions as a method and model for unity. The Orthodox signatories were representatives of nine churches, but the agreement was accepted by the representatives of nine out of 14 Orthodox Churches but not yet by their Synods nor by a Pan-Orthodox Council. Not all the Orthodox Churches received the documents, and the \"Uniate\" question remained suspended. On the Catholic side, the Ukrainian Greek Catholic bishops rejected all the documents produced by the international commission for dialogue, objecting in particular to the rejection of uniatism, which they regarded as the means by which their communities had resisted Soviet pressure. For the Orthodox, the core objection was that the Uniate model breaks communion with the orthodox \"Mother Churches\" and creates embitterment among the Orthodox. The commission continued its work in later plenary sessions, including Emmitsburg (2000), Belgrade (2006) and Ravenna (2007), which addressed ecclesiology, conciliarity and authority at local, regional and universal levels.\n\nMultilateral ecumenism and the World Council of Churches\n\nSeveral Orthodox churches took part in the World Council of Churches (WCC) from its foundation, but participation has been uneven and often contested. In 1998 the Ecumenical Patriarchate convened an inter-Orthodox meeting in Thessaloniki in response to requests from the Russian and Serbian Orthodox Churches, and to the withdrawal of the Georgian Orthodox Church from the membership of the WCC. Voices within many Orthodox churches, in particular lately those of Serbia and Russia, call for immediate withdrawal from the Council, and the Church of Jerusalem, although participating in local ecumenism, has for years abstained from sending delegates to WCC meetings. The Russian Church had already threatened to pull out of the WCC in 1997, with its representative criticizing the council's acceptance of women priests and its attitude toward homosexuals. After the Russian invasion of Ukraine in 2022, calls for the Russian Orthodox Church's removal from the WCC multiplied, and the WCC's central committee in June 2022 rejected the demand, citing the Moscow Patriarchate's commitment to dialogue under WCC auspices. In 2026 the WCC general secretary stated that governing bodies have previously declined to consider expulsion of the Russian Orthodox Church/Moscow Patriarchate and no such proposal is currently under consideration. Membership has therefore continued, and the WCC has not terminated the Russian Orthodox Church's membership, despite the explicit support for the invasion by the ROC's Patriarch.\n\nOrthodox views of ecumenism and the conditions for communion\n\nThe Orthodox position on ecumenism combines a commitment to dialogue with a firm view that unity must rest on a shared faith. The Holy and Great Council of Crete (2016) approved a text titled \"Relations of the Orthodox Church with the Rest of the Christian World,\" whose draft had been adopted by the Fifth Pan-Orthodox Conference in October 2015. The text states that the Orthodox Church has always attached great importance to dialogue, and especially to that with non-Orthodox Christians, while also insisting that it has never accepted theological minimalism or permitted its dogmatic tradition and evangelical ethos to be called into question. Dialogues are to proceed in conformity with \"canonical principles of Orthodox ecclesiology and the canonical criteria of the already established Church Tradition\". The council's reception was incomplete: thirty-three of the bishops participating in the council did not sign the document, and several local churches did not endorse it. Commentators also differ on the council's authority; some Orthodox theologians have called it ecumenical, while others remain skeptical that such an under-represented gathering can possibly amount to anything more than a local synod. The document itself is seen as reflecting a sense of \"a deep crisis in the ecumenical movement\" related to growing disagreement in matters of moral discernment among churches involved in ecumenical dialogue and cooperation.\n\nCommon ground and differences with Western traditions\n\nOrthodoxy and Catholicism share the Nicene confession of one, holy, catholic and apostolic Church, the apostolic succession of bishops, and a sacramental system of seven mysteries. Each recognizes the other's baptism in principle, and both regard the Eucharist as the centre of the Church's life. The divergences are structural and doctrinal. On papal authority, the Orthodox accept that Rome held a primacy of honour among the early patriarchal sees but reject any universal jurisdiction or the infallibility of the pope, as defined at the First Vatican Council in 1870. In ecclesiology, Orthodox theology emphasizes the Church as a communion of local churches gathered around their bishops, with conciliarity rather than a single centre of governance, whereas Catholic ecclesiology describes a universal Church whose unity is guaranteed by the bishop of Rome. Practical sacramental differences also persist: Orthodox churches administer chrismation together with baptism and give communion to infants, and they treat eucharistic communion as the visible expression of full ecclesial unity, a position that makes intercommunion difficult without agreement on doctrine and jurisdiction. The filioque clause, added to the Nicene Creed in the West, remains a central theological point of disagreement, alongside the disputed question of how the Church should respond to Uniate communities." }, { "heading": "Historiography and scholarly study", "text": "Western accounts of Byzantium have often been unfavourable. In many general histories the empire appears as a society in decline, marked by aristocratic display, a stifling bureaucracy and intellectual stagnation, or it is ignored altogether. Part of this negative judgement stems from the way key features of Byzantine intellectual life, such as its concern for religious orthodoxy and its distinctive rhetoric and education, were misread as unoriginal. The prejudice has older roots. One line of argument traces it to the ninth century, when Charlemagne's coronation in 800 led Western writers to deny the Byzantines a Roman inheritance, and this habit of calling them \"Greeks\" persisted in Western scholarship for centuries (the bias has a long history reaching back to the ninth century, and western sources from that time onward denied the Roman legacy to Byzantium).\n\nByzantium's marginalisation provoked its own reaction. Byzantium was cast as a decadent, effeminate foil to a vigorous Europe, and from the nineteenth century scholars in Orthodox countries answered with an idealised image of Byzantium serving modern political projects. A more favourable Western view came only in the late nineteenth and early twentieth centuries, partly as a late effect of Romanticism and Orientalism, when Byzantium could be seen as a mysterious and luxurious society of the past, and Byzantine art was the first modern field to present the culture in a positive light. Even so, Byzantine studies continued to be treated in the West as the \"poor relative\" of medieval studies. Scholars trained in classical philology, moreover, often examined Byzantium through the achievements of Greece and Rome. The discipline also has national dimensions: in Turkey, Byzantine studies initially rested on Western scholarship and received limited state support before a congress in Istanbul in 1955.\n\nRecent critical work has asked whether the field itself carries colonial assumptions. Cameron's critique of Anglophone writing argues that it still reflects a twin discourse of cultural bias and exoticism introduced by colonial-era historians who first narrated the Byzantine world for their British readers. The volume edited by Anderson and Ivanova takes up this question and argues that after 1453 Westerners took over the production and interpretation of Byzantine texts, many of them hostile to the empire. It also notes that even sympathetic outsiders imposed foreign logics on their reconstructions and interpretations of the Byzantine world, from political culture to ecclesiology. Whether nationalism or colonialism is the deeper source of the discipline's problems remains contested, and the editors deliberately decline to give a definitive answer.\n\nThe Great Schism is conventionally dated to 1054, when the legates of Rome and Patriarch Michael I Cerularius of Constantinople issued mutual excommunications. Historians have pointed out that these condemnations were directed at individuals rather than at whole churches, and that the separation developed over a long period of mutual suspicion, liturgical and doctrinal disputes, and political rivalry. The Fourth Crusade played a decisive role in deepening the rift. Initiated by Pope Innocent III to recapture Jerusalem, the crusade was diverted to Constantinople after Venice demanded payment, and the crusaders first attacked the Christian city of Zara. In April 1204 the crusaders took and sacked Constantinople. Innocent's condemnation shows that even within the medieval Catholic Church the diversion against a Christian city was understood as a serious violation of the crusading ideal rather than a legitimate military action. Scholars continue to weigh the motives behind the attack: Britannica, for example, describes it as driven primarily by greed, while other accounts emphasise Venetian commercial interests and Byzantine dynastic conflicts. Historians generally agree that the 1204 sack of Constantinople also widened the breach between the Eastern and Western churches. The Latin Empire that followed lasted until 1261, and historians have connected it both to accelerated Byzantine decline and to the deepening of the schism.\n\nHistoriography of these events has often reflected the parties involved. Queller and Madden's influential study of the Fourth Crusade adopts a Western European rather than a Byzantine perspective. More broadly, the scholarship of the Fourth Crusade exemplifies Western attitudes about Byzantium, as authors often took sides corresponding to the parties in the armed conflict.\n\nOrthodox theology as an academic discipline developed largely in institutions founded by émigrés and in the Orthodox diaspora. St Vladimir's Orthodox Theological Seminary, founded in 1938 in New York City, is one of the most influential examples. The seminary was granted the status of an \"Academy\" by the Holy Synod in 1948, an Absolute Charter by the Regents of the University of the State of New York in 1953, and full accreditation by the Association of Theological Schools in 1973. Its deans included Protopresbyters Georges Florovsky, Alexander Schmemann, John Meyendorff and Thomas Hopko, nearly a who's who list of twentieth-century theology. The Saint Sergius Institute in Paris, founded in 1925 by Russian émigré theologians, shared this formative role; Florovsky, for example, was instrumental in founding St Vladimir's after his departure from the Orthodox Theological Institute of St Sergius in Paris. Both institutions have trained generations of scholars in patristics, liturgy and Russian religious thought.\n\nCurrent debates concern the place of Orthodoxy within global Christianity and the role of Orthodox churches in national histories. Western-centred narratives of church history have tended to treat Orthodoxy as a peripheral or \"Eastern\" subject, while national historiographies in Orthodox countries have often used the Byzantine and medieval past to legitimate present identities. Anderson and Ivanova's argument that the field's discontents may stem more from nationalism than from colonialism places the question of national histories at the centre of the discussion.
