The Eastern Orthodox Church, officially the Orthodox Catholic Church, and also called the Greek Orthodox Church or simply the Orthodox Church, is the second-largest Christian church, with approximately 230 million baptised members. It operates as a communion of autocephalous churches, each governed by its bishops via local synods. The church has no central doctrinal or governmental authority analogous to the head of the Catholic Church. Nevertheless, the Ecumenical Patriarch of Constantinople is recognised by them as primus inter pares, a title formerly given to the patriarch of Rome. As one of the oldest surviving religious institutions in the world, the Eastern Orthodox Church has played an especially prominent role in the history and culture of Eastern and Southeastern Europe.
Eastern Christianity comprises Christian traditions and church families that originally developed during classical and late antiquity in Western Asia, Asia Minor, Eastern Europe, Southeastern Europe, the Caucasus, Northeast Africa, the Fertile Crescent and the Malabar coast of South Asia, and ephemerally parts of Persia, Central Asia and the Far East. The term does not describe a single communion or religious denomination.
The Ecumenical Patriarch of Constantinople is the Archbishop of Constantinople and primus inter pares among the heads of the several autocephalous churches which compose the Eastern Orthodox Church. The ecumenical patriarch is regarded as the representative and spiritual leader of the Eastern Orthodox Christians worldwide. The term ecumenical in the title is a historical reference to the Ecumene, a Greek designation for the civilised world, i.e. the Roman Empire, and it stems from Canon 28 of the Council of Chalcedon.
The highest-ranking bishops in Eastern Orthodoxy, Oriental Orthodoxy, the Catholic Church, the Hussite Church, Church of the East, and some Independent Catholic Churches are termed patriarchs.
Patriarchate is an ecclesiological term in Christianity, designating the office and jurisdiction of an ecclesiastical patriarch. According to Christian tradition three patriarchates were established by the apostles as apostolic sees in the 1st century: Rome, Antioch, and Alexandria. Constantinople was added in the 4th century and Jerusalem in the 5th century. Eventually, together, these five were recognised as the pentarchy by the Council of Chalcedon in 451.
The Eastern Catholic Churches or Oriental Catholic Churches, also called the Eastern-Rite Catholic Churches, Eastern Rite Catholicism, or simply the Eastern Churches, are 23 Eastern Christian autonomous particular churches of the Catholic Church, in full communion with the Pope in Rome. Although they are distinct theologically, liturgically, and historically from the Latin Church, they are all in full communion with it and with each other. Eastern Catholics are a distinct minority within the Catholic Church; of the 1.3 billion Catholics in communion with the Pope, approximately 18 million are members of the eastern churches.
An exarch was the holder of any of various historical offices, some of them being political or military and others being ecclesiastical.
The Patriarch of Antioch is a traditional title held by the bishop of Antioch. As the traditional "overseer" of the first gentile Christian community, the position has been of prime importance in Pauline Christianity from its earliest period. This diocese is one of the few for which the names of its bishops from the apostolic beginnings have been preserved. Today five churches use the title of patriarch of Antioch: one Oriental Orthodox ; three Eastern Catholic ; and one Eastern Orthodox.
An apostolic administration in the Catholic Church is administrated by a prelate appointed by the pope to serve as the ordinary for a specific area. Either the area is not yet a diocese, or is a diocese, archdiocese, eparchy or similar permanent ordinariate that either has no bishop or archbishop or, in very rare cases, has an incapacitated (arch)bishop.
The Melkite Greek Catholic Church, or Melkite Byzantine Catholic Church, is an Eastern Catholic church in full communion with the Holy See as part of the worldwide Catholic Church. Its chief pastor is Patriarch Youssef Absi, headquartered at the Cathedral of Our Lady of the Dormition in Damascus, Syria. The Melkites, who are Byzantine Rite Catholics, trace their history to the early Christians of Antioch, formerly part of Syria and now in Turkey, of the 1st century AD, where Christianity was introduced by Saint Peter.

The Catholic Church in Greece is part of the worldwide Catholic Church, under the spiritual leadership of the Pope in Rome. Indigenous Roman Catholic Greeks numbered about 50,000-70,000 in 2022 and were a religious and not an ethnic minority. Most of them are a remnant of Venetian and Genoese rule in southern Greece and many Greek islands from the early 13th until the late 18th century, Greeks who converted to Catholicism or descendants of the thousands of Bavarians that came to Greece in the 1830s as soldiers and civil administrators, accompanying King Otto. One very old but still common term to reference to them is Φράγκοι, or "Franks", dating to the times of the Byzantine Empire, when medieval Greeks would use that term to describe all Catholics.
The Catholic Church in North Macedonia is part of the worldwide Catholic Church, under the spiritual leadership of the Pope in Rome and is one of the major religious communities that exist on the territory of the Republic of North Macedonia.

The history of the Eastern Orthodox Church is the formation, events, and transformation of the Eastern Orthodox Church through time. According to the Eastern Orthodox tradition, the history of the Eastern Orthodox Church is traced back to Jesus Christ and the Apostles. The Apostles appointed successors, known as bishops, and they in turn appointed other bishops in a process known as Apostolic succession. Over time, five Patriarchates were established to organize the Christian world, and four of these ancient patriarchates remain Orthodox today. Orthodox Christianity reached its present form in late antiquity, when the ecumenical councils were held, doctrinal disputes were resolved, the Fathers of the Church lived and wrote, and Orthodox worship practices settled into their permanent form.
Joseph Sokolsky was the first senior Eastern Orthodox Bulgarian clergyman to convert to Catholicism, thus becoming a pioneer of the Bulgarian Byzantine Catholic Church. Sokolsky negotiated with Vatican a formal union due to Phanariotes domination over Bulgarian Orthodoxy and gained Catholic recognition in 1861 when Pope Pius IX named him Archbishop for the Bulgarians of the Byzantine Rite. He was also accepted in that capacity by the Ottoman Empire.
The Greek Catholic Eparchy of Mukachevo is an eparchy (diocese) of the Ruthenian Greek Catholic Church that was erected by the Pope Clement XIV in 1771. The geographic remit of the eparchy includes the south-western parts of Ukraine that are roughly within Zakarpatska Oblast. As an Eastern Catholic Church, it is in full communion with the Catholic Church. The eparchy is exempt, which means that it does have a metropolitan bishop but is directly subject to the Holy See. It is supervised by the Roman Dicastery for the Eastern Churches, a Roman Curia dicastery acting on behalf of the Pope. Its parishes observe the Byzantine Rite which is also celebrated by the majority of Orthodox Christians, and as provided for in the original terms of the Union of Uzhhorod. The episcopal seat is the Cathedral of the Exaltation of the Holy Cross in the city of Uzhhorod.

It uses two liturgical languages: Koine Greek, the traditional language of the Eastern Churches, and Albanian, the native language of most of its adherents.

The Territorial Abbacy of Santa Maria of Grottaferrata is an ecclesiastical jurisdiction which administers the Abbey of Saint Mary in Grottaferrata located in Grottaferrata, Rome, Lazio, Italy. The Abbacy and its territory are stauropegic, that is, directly subordinate to a primate or synod, rather than to a local bishop. It is the only remnant of the once-flourishing Italo-Greek monastic tradition. It is the only monastery of the Italian Basilian Order of Grottaferrata,, a religious order of the Italo-Albanian Catholic Church. The abbot ordinary is also the superior general of the Italian Basilian Order of Grottaferrata. Though normally led by an abbot, the Abbacy has been under the authority of Bishop Marcello Semeraro since Pope Francis named him Apostolic Administrator of the Abbacy on 4 November 2013.
