The Schism of Photius

The deposition of Ignatius

Ignatius, son of Emperor Michael I Rangabe, had been Patriarch of Constantinople since 847.^[7] Catholic sources stress that he clashed with Bardas, the powerful uncle of Emperor Michael III, and that he was banished on 23 November 857.^[8] The canonical difficulty lies in the fact that Ignatius did not freely renounce his see: if he remained the legitimate patriarch, any appointment to his see was invalid.^[9]

Photius was no mediocre figure placed there by chance. He belonged to the administrative and intellectual elite of Constantinople: imperial secretary, diplomat, scholar, author of the Myriobiblon and the Amphilochia.^[10] Even Catholic sources hostile to his conduct acknowledge his exceptional erudition.^[11][12]

The sensitive point is therefore not his competence, but his entry into the patriarchate. The tradition hostile to Photius stresses his accelerated promotion from lay status to the patriarchate within a few days. The Orthodox reading, for its part, presents his election as a solution of pacification after the deposition of Ignatius, which the East regarded as accepted or settled by a local synod.^[13][14]

Rome intervenes, then reverses its decision

In 861, a synod was held at Constantinople with Roman legates.^[15] They accepted the deposition of Ignatius and the recognition of Photius. But Pope Nicholas I subsequently rejected this decision: at Rome, a synod of 863 annulled the legates' action, recognized Ignatius as the legitimate patriarch and condemned Photius if he persisted in occupying the see.^[16][17]

This sequence gave the affair its ecclesiological scope. For Rome, the legates had judged badly or exceeded their mandate; the pope could correct their decision. For Constantinople, Rome was undoing after the fact a judgment rendered on the spot, turning an Eastern crisis into a demonstration of pontifical jurisdiction. The disagreement was already no longer only about Photius: it concerned Rome's competence in an Eastern patriarchal affair.

A crisis of jurisdiction

The legal heart of the matter is simple: can a living patriarch be removed by political pressure, then replaced by a layman rapidly promoted? The traditional Catholic answer is negative: Ignatius remains the titular holder so long as he has not freely renounced or been deposed according to the canons.^[18] The council of 869-870 therefore judged Photius as an intruder and confirmed Ignatius.^[19][20]

The later Orthodox answer lays greater stress on Eastern reception: the local bishops had accepted Photius, the Roman legates of 861 had at first confirmed this solution, and then the synod of 879-880 rehabilitated Photius with Roman legates present. That is why many Orthodox regard that last synod as the true settlement of the crisis.^[21]

Bulgaria, a missionary and political stake

Recently Christianized Bulgaria made the quarrel explosive. Prince Boris-Michael sought disciplinary answers and an ecclesiastical organization.^[22] Rome and Constantinople disputed jurisdiction over this young Church because it determined the religious balance of the Balkans.^[23] Photius accused the Latin missionaries of introducing foreign practices into Bulgaria; Rome reproached Constantinople with seizing a disputed mission field.^[24]

The Bulgarian conflict explains why apparently secondary questions became incendiary: the Saturday fast, the discipline of married priests, confirmation or chrismation, liturgical usages. In a still undivided Church, these divergences could have remained disciplinary; on a contested missionary frontier, they became markers of identity.

Photius's encyclical against the Latins

In 867, Photius wrote to the Eastern patriarchs and convened a synod against Rome.^[25] His letter accused the Latin missionaries in Bulgaria of having altered the received tradition. It listed several grievances: the Saturday fast, the practical rejection of the married clergy, the repetition of chrismation and above all the addition of the Filioque.^[26]

"They attempted, through false opinions and distorted words, to ruin the holy and sacred Nicene Symbol of Faith — which by both synodal and universal decisions possesses invincible power — by adding to it that the Holy Spirit proceeds not only from the Father, as the Symbol declares, but from the Son also." — Photius, encyclical to the Eastern patriarchs, 867^[27]

This accusation is historically momentous. Discussions of the Filioque already existed in the West, but Photius gave the controversy its first great Eastern anti-Latin formulation.^[28] For him, adding and the Son to the Creed altered the monarchy of the Father and introduced two principles into the Trinity. Catholic doctrine, for its part, is defined: at the Council of Florence (Laetentur caeli, decree for the Greeks, 6 July 1439), the Church confesses that the Holy Spirit proceeds eternally from the Father and the Son as from one single principle and by a single spiration — not as from two rival sources.^[29][30][31]

The Photian synod against Nicholas I

The synod of 867 went further than a doctrinal protest. It claimed to condemn and depose Pope Nicholas I.^[32] For Rome, this act was inadmissible: a local synod cannot judge and depose the Roman pontiff, especially in a case where Constantinople had requested Roman intervention.^[33]

Canon 6 of Constantinople IV preserved the Roman memory of this wound: Photius is condemned there for having assembled a synod against Nicholas, fabricated false patriarchal representatives and produced defamatory writings against the pope.^[34]

The political turning point of 867

The crisis turned that same year. Michael III was assassinated and Basil I the Macedonian took power.^[35] To consolidate his reign and secure Roman support, Basil removed Photius, recalled Ignatius and requested a general council together with Rome.^[36] Pope Nicholas died in November 867; his successor Adrian II took up the case, assembled a Roman synod in 869, then sent legates to Constantinople.^[37]

The council opened at Hagia Sophia on 5 October 869 and closed on 28 February 870.^[38] The acts preserved by Anastasius the Librarian mention the Roman legates Donatus, Stephen and Marinus.^[39] Twenty-seven canons were approved, and the Catholic tradition would count this council as the eighth ecumenical one.^[40][41]

The main decisions

Constantinople IV condemned Photius, confirmed Ignatius and burned the acts of the Photian synod of 867.^[42][43] But its decisions were not limited to a personal conflict. The council affirmed the canonical tradition, confirmed the veneration of images, condemned the theory of two souls in man and protected the election of bishops against pressure from the powerful.^[44][45]

Canon 21 also formulated the order of the patriarchates: Rome, Constantinople, Alexandria, Antioch, Jerusalem. It forbade composing insulting writings against the see of Peter and answered the synod of 867 directly.^[46]

Photius returns after the death of Ignatius

Photius was exiled, but he kept a powerful party. Basil recalled him in 876 and entrusted him with the education of his sons.^[47][48] Ignatius died on 23 October 877; the see then became genuinely vacant.^[49] Rome, under John VIII, accepted Photius's reconciliation and recognized him as patriarch, in the hope of stabilizing the East.^[50][51]

This moment is decisive for judging the affair fairly. The Catholic condemnation concerns the first occupation of Ignatius's see; after Ignatius's death, the question changed. Photius could henceforth be elected to a vacant see. The difficulty then lay in his memory of the council of 869-870, his anti-Latin policy and Bulgarian jurisdiction.

The synod of 879-880

A synod met at Hagia Sophia in 879-880.^[52] It rehabilitated Photius, practically annulled the decisions of 869-870 in Byzantine reception and affirmed the Creed without addition.^[53][54] The Orthodox tradition often sees in it a great council of restoration; the Catholic tradition does not receive it as ecumenical and keeps Constantinople IV in its list of councils.^[55][56]

The question of reception is therefore central. One and the same place, Hagia Sophia, carries two opposing memories: for Rome, the council of 869-870 manifests the legitimate judgment of the universal Church; for Orthodoxy, the synod of 879-880 corrects an excessive Roman intervention and restores the patriarch recognized by the East.

The Schism of Photius did not immediately create a permanent separation. After Photius's second deposition in 886, a form of communion returned between Rome and Constantinople for about a century and a half, until Michael Cerularius and the events of 1054.^[57]

But the episode left four lasting legacies. First, the Orthodox argument against the Filioque received its first great polemical formulation. Second, Roman primacy was henceforth perceived by part of the East as a foreign jurisdictional claim. Third, missionary competition in Slav lands showed that evangelization could become a field of rivalry between patriarchates. Finally, historical memory divided: the same events produced two incompatible ecclesial narratives.

This continuity explains why the articles on Orthodoxy, Constantinople IV and the future Great Schism of the East must be read together. Photius is not 1054, but he provided 1054 with a grammar of conflict: Rome and Constantinople already knew how to accuse each other of breaking with tradition.

The Schism of Photius is a conflict on several levels. At the immediate level, it concerns the legitimacy of a patriarch. At the canonical level, it asks who may judge the deposition of a patriarchal see. At the doctrinal level, it brings the Filioque to the forefront of the East-West controversy. At the political level, it reveals the weight of the Byzantine emperor and of Bulgaria in ecclesiastical affairs.

For a Catholic reader, the crisis shows the need for a visible principle of communion when a local Church is divided. For an Orthodox reader, it shows the danger of a Roman jurisdiction understood as external intervention in the life of the East. That is precisely why the episode remains important: it compels us to read history without reducing it to a confessional slogan.

• Read Constantinople IV for the Catholic council that condemned Photius.
• Read Answers on Orthodoxy for the questions of the Filioque, primacy and conciliar reception.
• Read The Great Schism of the East for the rupture of 1054.
• Remember the heart of the matter: Photius is not the sole cause of the Eastern schism, but the Photian crisis gave a first complete form to the tensions between Rome and Constantinople.
