The Orthodox Church of Ukraine (Ukrainian: Православна церква України, romanized: Pravoslavna tserkva Ukrainy; OCU), also called the Ukrainian Orthodox Church, is an Eastern Orthodox Church in Ukraine. It was granted autocephaly by the Ecumenical Patriarch of Constantinople on 6 January 2019.
Some of the Eastern Orthodox Churches recognize the Orthodox Church of Ukraine as the only canonical successor of the Metropolis of Kyiv.
Ukrainian Greeks are a Greek minority that reside in or used to reside in the territory of modern Ukraine. The majority of Ukrainian Greeks live in Donetsk Oblast and are particularly concentrated around the city of Mariupol.
According to the 2001 Ukrainian Census, there were 91,548 ethnic Greeks in Ukraine, or 0.2% of the population. However, the actual percentage of those with Greek ancestry is likely to be much higher due to widespread intermarriage between ethnic Greeks and those Ukrainian citizens who are Ukrainian Orthodox, particularly in eastern Ukraine, as well as the absence of strong links to Greece or use of the Greek language by many with Greek ancestry in these areas and who therefore are not classified as Greeks in official censuses.
Church Slavonic is the conservative Slavic liturgical language used by the Eastern Orthodox Church in Belarus, Bulgaria, North Macedonia, Montenegro, Poland, Russia, Ukraine, Serbia, the Czech Republic and Slovakia, Slovenia and Croatia. The language appears also in the services of the Russian Orthodox Church Outside of Russia, the American Carpatho-Russian Orthodox Diocese, and occasionally in the services of the Orthodox Church in America.
In addition, Church Slavonic is used by some churches which consider themselves Orthodox but are not in communion with the Orthodox Church, such as the Montenegrin Orthodox Church and the Russian True Orthodox Church. The Russian Old Believers and the Co-Believers also use Church Slavonic.
On 5 January 2019, Bartholomew I, the Ecumenical Patriarch of Constantinople, signed the tomos that officially recognized and established the Orthodox Church of Ukraine and granted it autocephaly (self-governorship). The events immediately leading to the grant of autocephaly were:
Metropolitan of Kyiv is an episcopal title that has been created with varying suffixes at multiple times in different Christian churches, though always maintaining the name of the metropolitan city — Kiev (Kyiv) — which today is located in the modern state of Ukraine. The church was canonically established and governed by the Ecumenical Patriarch of Constantinople in Kievan Rus'. Following the Council of Florence and the Union of Brest, there are now parallel apostolic successions: in the Russian Orthodox Church, the Orthodox Church of Ukraine, the Ruthenian Uniate Church and its successors. This list contains the names of all the metropolitan bishops (hierarchs) who have claimed the title. It is arranged chronologically and grouped per the claimed jurisdiction.
The Ukrainian Autocephalous Orthodox Church (UAOC; Ukrainian: Українська автокефальна православна церква (УАПЦ), romanized: Ukrayinska avtokefalna pravoslavna tserkva (UAPTs)) was one of the three major Eastern Orthodox churches in Ukraine in the late 20th and early 21st centuries, together with the Ukrainian Orthodox Church – Kyiv Patriarchate (UOC-KP) and the Ukrainian Orthodox Church – Moscow Patriarchate (UOC-MP). It began in 1921 during the dissolution of the Russian Empire as part of the Ukrainian independence movement and in order to restore the Ukrainian Orthodox Church that existed in the Polish-Lithuanian Commonwealth in 1620–1685 and was annexed by the Moscow Patriarchate without approval of the Ecumenical Patriarchate of Constantinople. The UAOC came to an end in December 2018 as it united with the UOC-KP into the newly formed Orthodox Church of Ukraine (OCU).
The UAOC, in its contemporary form, has its origins in the synod of 1921 in Kyiv, shortly after Ukraine's newly found independence. It was re-established for the third time on 22 October 1989, right before the fall of the Soviet Union. Unlike the UOC-KP, the UAOC enjoyed no recognition by the rest of the Orthodox Christian community until 11 October 2018, when the Ecumenical Patriarchate of Constantinople lifted the excommunication which had afflicted both the UAOC and the UOC-KP. It was clarified on 2 November 2018, however, that the Ecumenical Patriarchate recognized neither the UAOC nor the UOC-KP as legitimate and that their respective leaders were not recognized as primates of their churches. On 15 December 2018, at the unification council of the Eastern Orthodox churches of Ukraine, the UAOC and the UOC-KP, along with metropolitans from the UOC-MP, unified into the OCU.
The Ukrainian Orthodox Church – Kyiv Patriarchate (UOC-KP; Ukrainian: Украї́нська Правосла́вна Це́рква – Ки́ївський Патріарха́т (УПЦ-КП), romanized: Ukrainska Pravoslavna Tserkva — Kyivskyi Patriarkhat (UPTs-KP)) was an Orthodox church in Ukraine, in existence from 1992 to 2018. Its patriarchal cathedral was St Volodymyr's Cathedral in Kyiv.
After its unilateral declaration of autocephaly in 1992, the UOC-KP was not recognised by the other Eastern Orthodox churches, and was considered a "schismatic group" by the Moscow Patriarchate and Ecumenical Patriarchate. Patriarch Filaret (Denysenko) was enthroned in 1995 and excommunicated by the Russian Orthodox Church in 1997, an action not recognized by the UOC-KP synod. In 2018, the Ecumenical Patriarchate of Constantinople moved unilaterally and against canonical norms to facilitate a "unification council", in contradiction to his previous statement "recognizing the fullness of the Russian Orthodox Church's exclusive competence on this issue". The canonical Ukrainian Orthodox Church rejected these overtures, noting its universal recognition as sole canonical authority on the territory of Ukraine and the political nature of the proposed council. Constantinople ignored this, "reinstated" Filaret as a bishop and facilitated the convening of a unification council. In December 2018, the unification council of the Eastern Orthodox churches of Ukraine decided to unite the UOC-KP with the Ukrainian Autocephalous Orthodox Church (UAOC), creating the Orthodox Church of Ukraine (OCU) which was subsequently granted autocephaly by the Ecumenical Patriarch of Constantinople in January 2019.
A tomos (Greek: τόμος, romanized: tomos, lit. 'section', 'part of', 'part which is cut') in the Eastern Orthodox Church is a decree of the head of a particular Eastern Orthodox church on certain matters (such as the level of dependence of an autonomous church from its mother church).
Tomos is a Greek word; it can be literally translated as 'a section'. "In the narrower meaning in Orthodox church terminology, a tomos is [...] a scroll or a small book, but one with a very specific purpose — it codifies a decision by a Holy Synod, or council of Orthodox bishops." The translation of the word tomos in English is document.
Metropolitan Epiphanius of Kyiv and All Ukraine (Ukrainian: Епіфаній, Митрополит Київський і всієї України, romanized: Epifanii, Mytropolyt Kyivskyi i vsiiei Ukrainy, secular name: Serhii Petrovych Dumenko, Ukrainian: Сергій Петрович Думенко; born on 3 February 1979) is the primate of the Orthodox Church of Ukraine (OCU), holding the title of Metropolitan of Kyiv and All Ukraine.
Metropolitan Epiphanius served as the Metropolitan bishop of Pereiaslav and Bila Tserkva, in the former original Ukrainian Orthodox Church (Kyiv Patriarchate) from 2013 to 2018. He was ordained over the diocese since 2010.
