Catholic Orthodox Schism
Shades of christianity
The Catholic and Orthodox churches did not divide on one day. They grew apart for centuries, healed more than once, and only later treated the breach as permanent. The council of 869 is one of the early fractures, and it did not hold.
For the first centuries there was one church with several chief sees. Rome, Constantinople, Alexandria, Antioch and Jerusalem were the five patriarchates. Rome had a primacy of honour as the see of Peter and Paul, and the only apostolic see in the West. Constantinople had the emperor, the court, and from the sixth century the title “ecumenical patriarch.” Greek in the East, Latin in the West, different liturgies, and two ideas of authority were already in place before anyone spoke of a schism. The East thought of Rome as the senior patriarch, whose voice mattered most in a council. The popes of the ninth century were already claiming a jurisdiction that could judge other patriarchs.
Photius sat in the middle of that argument. In 858 the emperor Michael III deposed Patriarch Ignatius and replaced him with Photius, a lay scholar and head of the imperial chancery. He was elected, tonsured and ordained through the grades to the patriarchate within about a week. Ignatius’s party appealed to Rome. Pope Nicholas I refused to recognise the appointment. Canon law, as Rome read it, did not allow a layman to be rushed to the highest see, and it did not allow an emperor to depose a patriarch and have Rome rubber-stamp the result.
The fight then moved to Bulgaria. Both Rome and Constantinople wanted the new Bulgarian church. Nicholas wrote to the Bulgars attacking Greek customs: married clergy, the leavened bread of the Eucharist, and other rites. Photius answered in 867 with a council in Constantinople that deposed and anathematised Nicholas and the Western church. The charge that lasted was the Filioque. The Nicene-Constantinopolitan Creed says the Holy Spirit proceeds from the Father. In Spain, and then more widely in the Latin West, churches had added “and from the Son” — Filioque — to stress the Son’s full divinity against Arianism. Rome itself adopted the addition later. Photius called the addition a corruption of the creed and a theological error. The East’s objection was twofold: that the Spirit proceeds from the Father alone, the Son being involved in the Spirit’s sending but not in his eternal origin; and that no one see had the right to alter a creed fixed by an ecumenical council.
That council of 867 did not last the year. Basil I murdered Michael III, took the throne, and restored Ignatius. Nicholas died in November 867. His successor, Adrian II, condemned Photius, and Basil called the council that opened in Constantinople on 5 October 869. It sat until 28 February 870. It restored Ignatius, anathematised Photius, burned the acts of the 867 synod, and issued 27 canons. The papal legates pressed for a clear submission to Roman judgment. Attendance was poor: about a dozen bishops at the opening, never more than about a hundred. The West later counted this as the Fourth Council of Constantinople and the eighth ecumenical council. The East never did.
It also failed on the ground. Ignatius died in 877. Photius became patriarch again, with Basil’s support, and Pope John VIII recognised him in return for concessions on Bulgaria and a promise not to press the Filioque quarrel. A much larger council in Constantinople in 879–80 rehabilitated Photius, annulled the council of 869–70, and was accepted at the time by John VIII’s legates. Rome later repudiated that acceptance. Photius died in communion with Rome, or near enough to it that the breach closed. The Orthodox Church venerates him as a saint. The Catholic Church does not count his rehabilitating council.
What survived was the pair of questions. Does the Spirit proceed from the Father and the Son, or from the Father alone? And is the pope the monarch of the whole church, or the first among patriarchs who cannot rewrite a council’s creed or depose an eastern bishop on his own? Those questions were quiet for long stretches. They were not settled.
The date everyone remembers is 16 July 1054. Patriarch Michael Cerularius had closed Latin churches in Constantinople and attacked Western rites, especially unleavened bread. Pope Leo IX sent Cardinal Humbert. Humbert was abrasive, Leo had in fact already died, and on 16 July Humbert laid a bull of excommunication on the altar of Hagia Sophia. It named Cerularius and his supporters, and it condemned the Greek doctrine of the Spirit, married priests, and leavened bread. Cerularius excommunicated the legates in return. The two bulls did not excommunicate whole churches. Most bishops, east and west, never heard of them. Communion had already been patchy; it continued, in places, afterwards.
The split became a fact in the crusading era. The massacre of Latins in Constantinople in 1182, and then the Fourth Crusade’s sack of the city in 1204, turned a quarrel of theologians and patriarchs into a wound ordinary people remembered. A Latin patriarch was set up in Constantinople. Reunion was signed at the Second Council of Lyon in 1274 and again at Florence in 1439, both times under political pressure — the second time with the Ottoman siege already in view. Neither union survived contact with the eastern clergy and people. After 1453 Constantinople was Ottoman, and Moscow came to call itself the Third Rome. The anathemas of 1054 were lifted by Pope Paul VI and Patriarch Athenagoras in 1965. That removed a symbol. It did not restore communion.
So the council of 869 matters as a rehearsal. A pope and an emperor deposed a patriarch; a thin council ratified it; a fuller council undid it; Rome and Constantinople kept different memories of which council had spoken for the church. The later schism grew from that disagreement about authority, from the Filioque, and from the political rupture of 1204, not from a single anathema in 869 or 1054.

These are the standard “on this day” entries for 5 October. A few of the ancient dates are calendar conversions, and one revolutionary claim is looser than the list makes it sound.
539 BC — Babylon falls to Cyrus. The Nabonidus Chronicle puts the entry into the city on the 16th of Tašrītu in the 17th year of Nabonidus. Sippar had fallen two days earlier without a fight; Nabonidus fled, then was taken when he returned. The man who entered was Ugbaru (Gobryas), governor of Gutium, with Cyrus’s army. Cyrus himself came in about a fortnight later, in Arahsamna. Parker and Dubberstein’s Babylonian chronology converts the 16th of Tašrītu to 12 October Julian, which is about 5–6 October on the proleptic Gregorian calendar — hence the date on modern lists. The Cyrus Cylinder presents the takeover as peaceful and as the choice of Marduk; Herodotus and the book of Daniel remember a festival night and a breached river defence. What is solid is the political result: the Neo-Babylonian empire ended, and Cyrus’s edict let the Judean exiles go home. That is the hinge Second Isaiah and the book of Ezra both hang on.
456 — the Suebi broken on the Órbigo. Theodoric II, king of the Visigoths, moved into Iberia on the orders of the short-lived western emperor Avitus. With him were Burgundian forces under Chilperic I and Gundioc, and Frankish contingents. On the river Urbicus (the Órbigo), near Astorga in Gallaecia, they defeated the Suebi under Rechiar. Rechiar was captured and later executed. Suebic power in the north-west did not vanish at once, but the battle ended their bid to dominate the peninsula and left the Visigoths as the coming power in Hispania.
610 — Heraclius crowned. Heraclius, son of the exarch of Africa, sailed on Constantinople against the usurper Phocas. The Excubitors deserted, the city opened, and Phocas was killed — by Heraclius’s own hand in some accounts, after the exchange “Is this how you have ruled?” / “And will you rule better?” On 5 October, in the chapel of St Stephen in the Great Palace, Patriarch Sergius crowned him, and he married Fabia, who took the name Eudocia. He inherited a wreck: Avars in the Balkans, Khosrow II already using Maurice’s murder as a pretext for war. Syria, Palestine and Egypt would fall; the True Cross would be carried off. Heraclius’s answer was personal command, a rebuilt army, and the campaign that ended at Nineveh in 627. The peace he won was brief. Within a decade the same provinces were lost again, this time to the Arabs.
816 — Louis the Pious crowned at Reims. Louis was already emperor. Charlemagne had crowned him co-emperor at Aachen on 11 September 813, and he had ruled alone since his father’s death in 814. Pope Stephen IV came north anyway. On Sunday 5 October, during Mass at Reims, Stephen anointed him and set on his head a crown said to have been Constantine’s. Ermengarde was crowned with him and hailed Augusta. Louis had prostrated himself before the pope. The act did not make him emperor; it reattached the imperial title to a papal coronation, which Charlemagne’s 813 ceremony had sidestepped. Reims became the place where French kings were crowned.
869 — the council that deposed Photius. The Fourth Council of Constantinople, counted in the West as the eighth ecumenical council, opened on 5 October 869 and sat until 28 February 870. Emperor Basil I and Pope Adrian II wanted Photius out. Photius, a lay scholar raised abruptly to the patriarchate in 858, had been deposed once, restored, and had anathematised Pope Nicholas I in 867. The council restored Ignatius, anathematised Photius, burned the acts of his 867 synod, and issued 27 canons. Attendance was thin — a dozen bishops at the start, never more than about a hundred. The East does not receive it. Photius was patriarch again from 877, and the council of 879–80, far better attended, rehabilitated him. This is one of the fractures that later hardened into the schism.
1143 — Portugal recognised at Zamora. On 5 October, at Zamora, with the papal legate Cardinal Guido de Vico present, Alfonso VII of León and Castile — who styled himself emperor of the Spains — acknowledged his cousin Afonso Henriques as king of Portugal. Afonso had already won the field against his mother at São Mamede in 1128 and had used the royal title after Ourique in 1139. The text of the treaty is lost. What survived is the political fact: the Leonese crown stopped contesting the title, and Afonso signed as rex Portugallensis. Full papal recognition waited until Alexander III’s bull Manifestis Probatum in 1179. Portugal still marks 5 October, though the modern national holiday is the republic of 1910, not Zamora.
1450 — Jews expelled from Lower Bavaria. Louis IX, Duke of Bavaria-Landshut, called Louis the Rich, ordered the Jews out of his part of Bavaria. This sits in the long fifteenth-century squeeze on German Jewish communities — debt cancellation dressed as piety, local expulsions before the larger ones of the 1490s. It was not the end of Jewish life in all Bavaria; Regensburg’s community lasted until 1519. It was a ducal clearance of Lower Bavaria.
1550 — Concepción founded. Pedro de Valdivia founded the city on 5 October 1550, at Penco on the Bay of Concepción, as a southern anchor of Spanish Chile against the Mapuche frontier. Earthquakes and Araucanian war forced later moves; the modern city stands inland of that first site. The date is the official foundation.
1582 — a day that did not happen. Pope Gregory XIII’s bull cut ten days from October so that the spring equinox, and therefore Easter, would fall where the Council of Nicaea had put it. In Italy, Spain, Portugal and the Polish–Lithuanian lands, 4 October was followed by 15 October. The 5th through the 14th do not exist in those countries for that year. France waited until December; Protestant states longer; Britain until 1752.
1607 — the knives and Paolo Sarpi. Sarpi, a Servite friar and Venice’s theological adviser in the Interdict fight with Paul V, was attacked on the night of 5 October as he came down the bridge by Santa Fosca toward his convent. Five men; fifteen thrusts by the count of holes in hat, hood and collar; three wounds that landed, one stiletto left in the cheekbone. He lived. Asked who had done it, he said Agnosco stylum Romanae Curiae — “I recognise the style of the Roman Curia,” with stilus also meaning dagger. The attackers fled toward the papal nuncio’s house and on to Rome. Venice gave him a safer lodging. He went back to his work on the history of the Council of Trent.
1665 — Kiel. Christian Albert, Duke of Holstein-Gottorp, founded the university on 5 October. It still bears his name: Christian-Albrechts-Universität.
1789 — the women march to Versailles. On the morning of 5 October, women from the Paris markets, after days of bread shortage and rumour, set off for Versailles. They wanted grain, and they wanted the king to sanction the August decrees and the Declaration of the Rights of Man. The National Guard followed under Lafayette, partly to lead the march and partly to keep it from becoming a sack. That night and the next morning the palace was invaded; two guards were killed. On the 6th Louis XVI agreed to move to Paris. The court came back to the Tuileries in the train of the crowd. The revolution ceased to be something that happened at a safe distance from the king.
1793 — the calendar, not a single act of abolition. Lists often say Christianity was disestablished in France on this day. What the Convention actually did on 5 October 1793 was accept Gilbert Romme’s scheme for a republican era beginning on 22 September 1792, the day the Republic had been proclaimed. The calendar itself was decreed on 24 October and backdated. Sunday disappeared; saints’ days were replaced by the names of plants, tools and weather; the aim was to take Christian time out of ordinary life. Dechristianisation was already a campaign — closed churches, the Cult of Reason, death for non-juring priests and those who hid them — not a statute passed on the 5th that ended the faith by decree. The Republican calendar lasted until 1806.
The day runs from a change of empire in Babylon to a change of calendar in Paris, with coronations, a council, a new kingdom and a failed killing in between.
