V. THE MEDIEVAL WORLD — c.500 – 1500 CE
How many
About 220 million. Roughly half are in Russia.
Who began it
No founder; the eastern half of the ancient undivided church, which regards itself as that church continuing unchanged.
What it is for
Theosis — deification. Athanasius' formula is that God became man so that man might become god, meaning participation in God's energies, not in his essence. This is the organising goal of Orthodox spirituality and it differs in emphasis from the Western focus on guilt and pardon.
What it worships
The Trinity. Strong emphasis on the incomprehensibility of God's essence and the accessibility of his energies, a distinction formalised by Gregory Palamas.
What it holds
Authority rests in Holy Tradition, of which scripture is part, and is expressed through the seven ecumenical councils. The filioque — the Western addition to the creed saying the Spirit proceeds from the Father and the Son — is rejected as an unauthorised change to a conciliar text. The pope is honoured as first in rank among bishops but has no universal jurisdiction; the church is a communion of self-governing (autocephalous) churches, not a monarchy. Ancestral rather than inherited-guilt original sin. No purgatory in the Latin sense, no indulgences, and no doctrine of the immaculate conception, which the Orthodox regard as answering a problem they do not have.
What it does
The Divine Liturgy of John Chrysostom, sung throughout, usually without instruments. Icons, venerated but not worshipped, understood as windows rather than pictures, and defended at enormous cost during the iconoclast controversy. Leavened bread and communion by spoon in both kinds. Infant baptism by triple immersion, with chrismation and communion given immediately. The Jesus Prayer and hesychasm, an inner tradition of stillness centred on Mount Athos. Married men may be ordained priests; bishops are drawn from monastics. Fasting is extensive, roughly half the year for the observant.
After death
Resurrection and judgment. Orthodoxy is deliberately reticent about the mechanics — the toll houses, a vivid account of the soul's post-mortem examination, are a widespread pious belief and not a dogma, and are disputed inside the church. Prayer for the dead is universal. Some Fathers, notably Gregory of Nyssa and Isaac of Nineveh, taught or hoped for universal restoration, and Orthodoxy has never resolved the question the way the West has.
Its texts
Bible with the Septuagint Old Testament. The seven ecumenical councils. The Philokalia, an anthology of ascetic texts compiled in 1782 that shaped modern Orthodox spirituality. The Greek Fathers: Basil, the Gregories, Chrysostom, Maximus the Confessor, John of Damascus, Gregory Palamas.
Its branches
Fourteen or fifteen autocephalous churches — Constantinople, Alexandria, Antioch, Jerusalem, Russia, Serbia, Romania, Bulgaria, Georgia, Cyprus, Greece, Poland, Albania, Czech Lands and Slovakia, and the disputed Ukrainian church. Old Believers split in 1666 over ritual reform.
Of note
Orthodoxy's self-understanding is that it has not changed. Whether that is historically accurate is arguable, but it explains why almost every conflict with Rome is framed as the West having added something.
Its timeline
- 330 CE Constantinople founded as the new capital.
- 726–843 CE Iconoclasm, twice imposed and twice defeated; the Triumph of Orthodoxy in 843 is still celebrated annually.
- 863 CE Cyril and Methodius begin the Slavic mission, inventing an alphabet so that scripture could be read in the vernacular.
- 988 CE Rus converts under Vladimir.
- <strong>1054 CE</strong> Mutual excommunications between papal legates and the patriarch of Constantinople. The conventional date of the schism, though the real separation was gradual.
- <strong>1204 CE</strong> The Fourth Crusade sacks Constantinople. Western crusaders loot the greatest Christian city in the world and desecrate Hagia Sophia. This, far more than 1054, made the division permanent in Orthodox memory.
- 1341–1351 CE Palamite councils affirm hesychasm and the essence-energies distinction.
- 1439 CE Council of Florence attempts reunion; it is repudiated by the Orthodox faithful.
- 1453 CE Constantinople falls to the Ottomans; the patriarchate continues under Ottoman administration.
- 1589 CE Moscow patriarchate established; Russia claims the mantle of the Third Rome.
- 1917–1988 CE Soviet persecution. Tens of thousands of clergy killed; the church survives and revives after 1988.
- 2018–2019 CE Constantinople grants autocephaly to the Orthodox Church of Ukraine; Moscow breaks communion. The largest Orthodox rupture in centuries, and it is about jurisdiction and war, not doctrine.
