Ukrainian Autocephaly and the 2018 Schism

In 2018–2019 the Ecumenical Patriarchate of Constantinople granted autocephaly to a newly unified Orthodox Church of Ukraine (OCU), reversing — on its own account — a 332-year-old arrangement under which the Metropolitanate of Kyiv had been administered from Moscow. The Russian Orthodox Church regarded the entire process as an uncanonical invasion of its territory and severed communion with Constantinople on October 15, 2018; that rupture, and the further breaks with Alexandria, Greece, and Cyprus as each recognized the OCU, remain unhealed as of 2026. This is the most serious division within the Orthodox Church in modern times, and every contested claim below is sourced to both sides.

Tradition: Pan-Orthodox (live inter-Orthodox dispute — both positions documented)

Background: The 1686 Transfer and Its Disputed Meaning

The roots of the dispute lie in 1686, when the Metropolitanate of Kyiv — historically a part of the Ecumenical Patriarchate — came under the administration of the Patriarchate of Moscow. The transfer was effected by synodal letters of Ecumenical Patriarch Dionysius IV, in the context of the Russo-Polish negotiations of the period (Brill, “Kyiv Metropolia and Moscow Diplomacy: an Ottoman Viewpoint,” Scrinium 15, 2019; “Annexation of the Metropolis of Kyiv by the Moscow Patriarchate,” Wikipedia).

The meaning of the 1686 act is itself contested, and the two churches read the same documents in opposite ways:

Moscow’s interpretation. The Russian Orthodox Church holds that 1686 was a full and permanent cession of the Kyiv metropolitanate to Moscow, complete and irrevocable, on the strength of which Moscow has governed the Church in Ukraine canonically for over three centuries (Moscow Patriarchate statements, 2018; “Annexation of the Metropolis of Kyiv by the Moscow Patriarchate,” Wikipedia).
Constantinople’s interpretation. The Ecumenical Patriarchate holds that the 1686 letters granted Moscow only the right to ordain (consecrate) the Metropolitan of Kyiv, on conditions — that the metropolitan continue to commemorate the Ecumenical Patriarch and that Constantinople’s status as mother church be preserved — and that the act was a temporary, conditional arrangement, not an alienation of canonical territory. On October 11, 2018 its synod declared the 1686 letter to have been issued “in violation of the sacred canons” and revoked its effect (Ecumenical Patriarchate synodal communiqué, October 11, 2018; Kyiv Post, “Constantinople revokes effect of 1686 tomos,” 2018).

Historians note a further complication relied on by Constantinople: in 1687 a council at Constantinople condemned Dionysius IV and deposed him, and the legitimacy of his transfer was questioned by some of his successors — a point Constantinople cites and Moscow disputes as to its bearing on the 1686 act’s validity (Grokipedia, “Dionysius IV of Constantinople”; Scrinium 15, 2019).

The Three Ukrainian Bodies Before 2018

On the eve of the 2018 process, Orthodoxy in Ukraine was divided among three bodies (Denysenko, The Orthodox Church in Ukraine: A Century of Separation, 2018; “Autocephaly of the Orthodox Church of Ukraine,” Wikipedia):

Ukrainian Orthodox Church (Moscow Patriarchate) — UOC-MP. A self-governing church under the Moscow Patriarchate, led by Metropolitan Onufriy (Berezovsky), with roughly 12,000 parishes — by far the largest body, and the only one recognized as canonical by the rest of world Orthodoxy until 2018.
Ukrainian Orthodox Church – Kyiv Patriarchate — UOC-KP. Founded in 1992 under former Metropolitan Filaret (Denysenko), who was deposed by Moscow in 1992 and anathematized in 1997; some 4,800 parishes. Regarded by other Orthodox churches as schismatic and unrecognized.
Ukrainian Autocephalous Orthodox Church — UAOC. A body tracing its origins to 1921, revived in the late Soviet period, led by Metropolitan Makariy (Maletych); roughly 1,000 parishes. Also unrecognized.

The 2018 Sequence

April 2018. Ukrainian President Petro Poroshenko, together with the leaders of the UOC-KP and UAOC, formally petitioned Ecumenical Patriarch Bartholomew for a tomos of autocephaly; the Ecumenical Patriarchate’s synod (April 19–20) resolved to proceed with the necessary steps (“Autocephaly of the Orthodox Church of Ukraine,” Wikipedia).
September 7, 2018. Constantinople appointed two exarchs to Kyiv — Archbishop Daniel (Zelinsky) of Pamphilon and Bishop Hilarion (Rudnyk) of Edmonton — “within the framework of the preparations for the granting of autocephaly,” a step Moscow regarded as an unauthorized incursion into its territory.
September 8–14, 2018 (Moscow’s first response). The Russian Holy Synod expressed “resolute protest”; on September 14 it announced retaliatory measures — suspending commemoration of Patriarch Bartholomew in the diptychs, suspending concelebration with Constantinople’s hierarchs, and withdrawing from episcopal assemblies and theological dialogues chaired by Constantinople’s representatives (“2018 Moscow–Constantinople schism,” Wikipedia).
October 11, 2018. The Ecumenical Patriarchate’s synod announced it would proceed to grant autocephaly; revoked the 1686 letter; and lifted the anathemas/depositions on Filaret and Makariy, declaring them “canonically reinstated” and their faithful restored to communion (Ecumenical Patriarchate communiqué, October 11, 2018).
October 15, 2018 (the rupture). The Holy Synod of the Russian Orthodox Church, meeting in Minsk, fully severed eucharistic communion with the Patriarchate of Constantinople, declaring it impossible to concelebrate or commune with Constantinople so long as it persisted; ROCOR’s Synod declared its “complete support” on October 18 (Moscow Patriarchate Holy Synod statement, October 15, 2018; ROCOR Synod statement, October 18, 2018 — see ROCOR Today: Current Structure).
December 15, 2018 (Unification Council). A council in St. Sophia, Kyiv, drawing together the UOC-KP, the UAOC, and two bishops from the UOC-MP, voted to unite into the Orthodox Church of Ukraine and elected Metropolitan Epiphanius (Dumenko), a protégé of Filaret, as its primate.

The Tomos of Autocephaly (January 5–6, 2019)

On January 5, 2019 Patriarch Bartholomew signed the Patriarchal and Synodal Tomos bestowing autocephaly on the OCU; on January 6 (Theophany) he read it and handed it to Metropolitan Epiphanius after a joint Liturgy at the Patriarchal Church of St. George in the Phanar (Ecumenical Patriarchate, “Tomos of Autocephaly,” ec-patr.org). Its actual provisions, which became points of contention, include:

The church is named the “Most Holy Church of Ukraine,” its primate styled “His Beatitude the Metropolitan of Kyiv and All Ukraine,” taking his place in the diptychs after the primate of the Church of the Czech Lands and Slovakia (Tomos text, ec-patr.org).
A territorial limitation: the OCU may not establish bishops or “extraterritorial altars” beyond the borders of Ukraine; its diaspora parishes are to come under the Ecumenical Throne — a clause critics and even some supporters read as keeping the OCU dependent on Constantinople for its presence abroad.
The OCU must receive the Holy Myron (chrism) from the Great Church of Christ (Constantinople), “as affirmation of its spiritual unity” — i.e., it does not consecrate its own chrism.
The right of hierarchs and clergy to appeal to the Ecumenical Patriarch is reserved, and Constantinople is named the mother church.

Critics (Moscow foremost) argue these clauses make the OCU’s autocephaly incomplete or qualified — more dependent on Constantinople than the older autocephalies — while the Ecumenical Patriarchate presents them as the normal marks of a daughter church’s relation to its mother see (Talk About: Law and Religion, “Ukrainian Autocephaly, One Year On,” 2020).

Recognitions Since — and Their Consequences

Constantinople’s grant did not produce immediate pan-Orthodox recognition. Of the fourteen autocephalous churches, four have recognized the OCU, and each recognition drew a corresponding break from Moscow (“2018 Moscow–Constantinople schism,” Wikipedia; “A Timeline of the Moscow–Alexandria Schism,” OrthoChristian.com/144060):

Church of Greece (October 2019). The Hierarchy recognized Constantinople’s right to grant autocephaly; on October 21, 2019 Archbishop Ieronymos II of Athens sent a peace letter to Epiphanius. Moscow responded by ceasing to commemorate Archbishop Ieronymos (Patriarch Kirill first omitted him on November 3, 2019).
Patriarchate of Alexandria (November 2019). Patriarch Theodore II commemorated Epiphanius and recognized the OCU; Moscow broke communion with Theodore II and ceased commemorating him (announced December 26, 2019), and — most consequentially — moved into Africa (below).
Church of Cyprus (2020). Archbishop Chrysostomos II commemorated Epiphanius on October 24, 2020, initially without his synod’s prior consent; the synod subsequently (by majority) accepted the commemoration. Moscow’s Holy Synod resolved on November 20, 2020 that Patriarch Kirill could no longer commemorate Chrysostomos II.

In every case Moscow’s response combined a break in the diptychs (ceasing to name the recognizing primate) with concelebration bans: ROC clergy are forbidden to concelebrate with the recognizing hierarchs and, on Mount Athos, ROC pilgrims were restricted from communing except at the Russian St. Panteleimon Monastery (“2018 Moscow–Constantinople schism,” Wikipedia).

The Churches That Have Not Recognized

As of 2026 the OCU is recognized by Constantinople, Alexandria, Greece, and Cyprus only. The remaining churches have withheld recognition: Russia (which actively opposes it), and — to varying degrees of neutrality or opposition — Antioch, Jerusalem, Serbia, Romania, Bulgaria, Georgia, Poland, Albania, the Czech Lands and Slovakia, and the Orthodox Church in America (OCA). Several have called for a pan-Orthodox resolution rather than taking sides (“2018 Moscow–Constantinople schism,” Wikipedia).

The African Exarchate

In retaliation for Alexandria’s recognition, the Russian Holy Synod on December 29, 2021 received 102 African clergy who had petitioned to leave the Patriarchate of Alexandria and established a Patriarchal Exarchate of Africa with two dioceses. The Ecumenical Patriarchate and Alexandria condemned this as an uncanonical invasion of Alexandria’s ancient territory; Alexandria’s synod declared the Russian exarch and clergy defrocked (Patriarchal Exarchate of Africa, exarchate-africa.ru; Archons of the Ecumenical Patriarchate, “The Moscow Patriarchate’s Uncanonical Incursion into Africa”; OrthoChristian.com/149587). The African exarchate marks the conflict’s spread beyond Slavic and Greek territory into a third continent.

Parish-Transfer Disputes and Claims of Violence

Within Ukraine, the formation of the OCU triggered a contested process of parishes leaving the UOC-MP. Between January 2019 and May 2024, roughly 1,700 communities announced transfers to the OCU; the pace accelerated sharply after Russia’s February 2022 invasion (Wikipedia, “Transition of church communities to OCU”; Spiritual Front, df.news, 2024). The two sides document the process very differently:

OCU and Ukrainian-state accounts describe transfers as voluntary decisions of local communities ratified under Ukrainian law (a 2019 law allowing a parish’s registered community to change jurisdiction), and OCU activists have themselves condemned violence during transitions and called on leaders to restrain it (RISU / Euromaidan Press, “OCU activists implore leaders to condemn violence during parish transfers,” November 2023). Ukrainian courts, including the Supreme Court in 2024, have upheld the legality of contested transfers (df.news, April 2024).
UOC-MP accounts describe the same events as forcible seizures of churches by local authorities and nationalist activists, asserting that transfer decisions were taken by territorial communities (residents living nearby) rather than by actual parishioners, and alleging over a hundred contested takeovers with episodes of vandalism and assault; the Russian foreign ministry has compiled such claims (Union of Orthodox Journalists; mid.ru, “Illegal actions by the Kiev regime targeting the Ukrainian Orthodox Church”). Independent verification of the competing tallies is limited, and reporting notes that both sides allege injuries and threats (per the reporting collated above; figures and characterizations remain disputed as of 2026).

Effects on World Orthodoxy (as of 2026)

The Moscow–Constantinople communion remains broken as of 2026, the longest and most serious rupture between the two senior sees in modern history; the breaks with Alexandria, Greece, and Cyprus likewise persist, and concelebration bans continue to fracture liturgical life in the diaspora and on Athos. The dispute has hardened two rival readings of Orthodox order: a Constantinopolitan account, in which the Ecumenical Patriarchate possesses the prerogative to grant autocephaly and to receive appeals across jurisdictional lines, and a Moscow account, in which such acts without pan-Orthodox consensus are uncanonical invasions of another church’s territory. No pan-Orthodox council has resolved the matter.

The War’s Impact

Russia’s full-scale invasion of Ukraine on February 24, 2022 transformed the landscape. Patriarch Kirill publicly framed and blessed the war as a defense of the “Russian world” against a “depraved” West (sermon of March 6, 2022), drawing condemnation across world Orthodoxy. Under that pressure the UOC-MP itself moved away from Moscow: at a council on May 27, 2022 it declared “full independence and autonomy” and removed references to its subordination to the Moscow Patriarchate from its statute — though Moscow does not recognize this independence as canonically effected, and critics question how complete the separation is (lb.ua, “UOC-MP declares ‘full independence’”; Public Orthodoxy, “Six Months Later,” December 2022). The war thus produced a third Ukrainian trajectory alongside the OCU and the residual Moscow-aligned body. The Russian-church dimension of these events — the “Russian world” ideology, the UOC-MP’s status, and the war’s ecclesial fallout — is treated in detail from the Russian side in Ukraine and the Russian Church.

Scholarly anchors frame the dispute along predictable lines. Nicholas Denysenko (The Orthodox Church in Ukraine: A Century of Separation) reads Ukrainian autocephaly as the long-sought fulfillment of a century-old movement for a church “subordinate to no one but God,” and as a challenge to Russian ecclesial imperialism (Denysenko, Canopy Forum, 2022). Cyril Hovorun, himself a Constantinople-jurisdiction Ukrainian theologian, defends Constantinople’s right to act while candidly noting that the Ecumenical Patriarchate “had to take over” the unification process because the two schismatic groups could not cooperate, and that the tomos’s terms could be revisited if the OCU revised its statutes (Hovorun, The Cause of Ukrainian Autocephaly, Routledge 2020; OrthoChristian.com/118074). Moscow-aligned canonists, by contrast, treat the whole sequence as void from the revocation of 1686 onward.
