Christianity

Origin 988

Ukrainian Orthodoxy shares its origin with the Russian church in the 988 baptism of Kievan Rus at Kyiv. Its modern jurisdiction is genuinely contested: the Orthodox Church of Ukraine received a Tomos of Autocephaly from the Ecumenical Patriarchate in January 2019, recognized by some Orthodox churches and not by others, while the Ukrainian Orthodox Church previously under the Moscow Patriarchate declared expanded independence in 2022 on terms whose canonical status remains disputed.

History & Origin

Traces its Christian origin to the 988 baptism of Kyivan Rus under Grand Prince Vladimir, and gained recognition as an autocephalous church distinct from the Moscow Patriarchate through the Ecumenical Patriarchate's 2019 Tomos.

Membership Over Time

A 2022 Razumkov Centre opinion survey, reported by the Religious Information Service of Ukraine, found that 5.5 percent of Ukrainians identified themselves as faithful of the church then under the Moscow Patriarchate, against 35.2 percent identifying with the rival Orthodox Church of Ukraine. 7

Membership Over Timethe subject's own account

In a 2008 analysis, the geopolitical research firm Stratfor estimated that more than fifty percent of the Ukrainian population belonged to the Ukrainian Orthodox Church, then under the Moscow Patriarchate. 8

Law and State

Ban or Official Watchlist

A 2024 Ukrainian law bans the activity of religious organisations found to be affiliated with or directed from the Russian Federation, a measure aimed principally at the Ukrainian Orthodox Church, historically linked to the Moscow Patriarchate. Ukraine's government frames the law as a wartime security measure; it has been described internationally, including by some religious freedom monitors, as raising concerns about religious persecution of the church. 6

Two jurisdictions claim Ukrainian Orthodox loyalty today 3

the subject's own accountThe Orthodox Church of Ukraine (OCU) formed from a December 2018 unification council and received a Tomos of Autocephaly from the Ecumenical Patriarchate in January 2019; it is recognized as canonical by the churches of Constantinople, Greece, Alexandria and Cyprus. The Ukrainian Orthodox Church previously under the Moscow Patriarchate (UOC-MP) declared expanded independence from Moscow in May 2022, after Russia's invasion of Ukraine, but whether this constitutes genuine autocephaly is itself disputed, since only a recognized autocephalous church or the Ecumenical Patriarchate can properly confer that status. The Moscow Patriarchate does not recognize the OCU and broke communion with Constantinople over the 2019 Tomos. This entry states both positions without adjudicating between them.

Shared Roots, Divergent Paths

Ukrainian Orthodox Christianity traces to the same 988 baptism of Kievan Rus that the Russian church claims as its own founding moment, since Kyiv, not Moscow, was the political and religious center of the Rus lands converted under Prince Vladimir. For centuries the Metropolitanate of Kyiv held a senior, largely autonomous place under the Ecumenical Patriarchate even as political power in the Rus lands shifted northward after the Mongol conquest.

In 1686 the Ecumenical Patriarchate transferred the Kyiv Metropolitanate to the jurisdiction of the Moscow Patriarchate, an act whose canonical propriety Constantinople itself later disputed, ruling in 2018 that the original transfer had been intended as temporary and improperly exercised. For the following three centuries most Ukrainian Orthodox life was administered from Moscow, though rival Ukrainian jurisdictions repeatedly asserted independence, including a short-lived Ukrainian Autocephalous Orthodox Church proclaimed in 1921 and suppressed under Soviet rule, and further autocephalous and independent bodies that formed after Ukrainian independence in 1991 but received no wide international recognition for decades.

By the early twenty-first century, Ukrainian Orthodoxy existed as several competing jurisdictions claiming the same territory and often the same parishes, a fragmentation the events described in the following article attempted, only partially, to resolve.

The 2018-2019 Tomos and Its Aftermath

In December 2018 a unification council in Kyiv merged Ukraine's previously unrecognized Ukrainian Autocephalous Orthodox Church and Kyivan Patriarchate bodies into a single new Orthodox Church of Ukraine, and on 6 January 2019 Ecumenical Patriarch Bartholomew I granted this new church a Tomos of Autocephaly, formal recognition as an independent, self-governing church. The Ecumenical Patriarchate's own churches, along with the churches of Greece, Alexandria and Cyprus, subsequently recognized the Orthodox Church of Ukraine as canonical; the Moscow Patriarchate did not, and broke communion with Constantinople itself over the decision, a rupture other Orthodox churches have responded to differently and that remains unresolved across the Orthodox world.

The competing body, the Ukrainian Orthodox Church that had remained under Moscow's jurisdiction, declared in May 2022, following Russia's full scale invasion of Ukraine that February, that it was severing practical ties to the Moscow Patriarchate and adopting full independence. Whether this declaration constitutes genuine autocephaly, a status only a recognized autocephalous church or the Ecumenical Patriarchate can properly confer, is itself disputed: the church's own statutes and canonical relationships remain contested both within Ukraine and among outside observers, and Ukrainian civil authorities have separately moved to restrict the Moscow-linked church's legal operation. This entry describes both positions rather than adjudicating between them; the underlying dispute over recognition and canonical status remains genuinely unsettled.

A New Calendar Widens the Break With Moscow

On 27 July 2023 a Local Council of the Orthodox Church of Ukraine, the body Constantinople had granted its own tomos of autocephaly in January 2019, voted to adopt the Revised Julian calendar, effective from the start of the new church year on 1 September that same year. The change moved every fixed feast thirteen days earlier: Christmas, kept for a century on the unrevised Julian date of January 7, was observed on December 25 for the first time that December, alongside the rest of the calendar's fixed observances. Parishes and monasteries that preferred to keep the old dates were told they could continue to do so, so the reform reached the church gradually rather than by decree alone.

The timing was not separate from the war. The decision followed Russia's full scale invasion in February 2022 by a little over a year, and it widened a break with Moscow that the 2019 tomos had already opened. The Julian calendar itself had come to be read in Ukraine as a marker of Russian church culture specifically, not simply of Orthodox tradition in general, and moving off it read as a further, deliberate step away from Moscow rather than as a change made for its own sake.

Where the six other Orthodox churches this atlas covers arrived at their calendar decisions across the 1920s, the Ukrainian church's decision is the newest, and its reasoning is explicitly the war.
