Primate (bishop) in the context of "Eastern Orthodox Christianity"

Eastern Orthodoxy, otherwise known as Eastern Orthodox Christianity or Byzantine Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or "canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones. Autocephalous churches choose their own primate. Autocephalous churches can have jurisdiction (authority) over other churches, some of which have the status of "autonomous" which means they have more autonomy than simple eparchies.

Many of these jurisdictions correspond to the territories of one or more modern states; the Patriarchate of Moscow, for example, corresponds to Russia and some of the other post-Soviet states. They can also include metropolises, bishoprics, parishes, monasteries, or outlying metochia corresponding to diasporas that can also be located outside the country where the primate resides (e.g., the case of the Ecumenical Patriarchate of Constantinople whose canonical territory is located partly in northern Greece and the east); sometimes they overlap (the case of Moldova where the jurisdictions of the patriarchs of Bucharest and of Moscow overlap).

The Church of Greece (Greek: Ἐκκλησία τῆς Ἑλλάδος, romanized: Ekklēsía tē̂s Helládos, IPA: [ekliˈsi.a tis eˈlaðos]), part of the wider Greek Orthodox Church, is one of the autocephalous churches which make up the communion of Eastern Orthodox Christianity. Its canonical territory is confined to the borders of Greece prior to the Balkan Wars of 1912–1913 ("Old Greece"), with the rest of Greece (the "New Lands", Crete, and the Dodecanese) being subject to the jurisdiction of the Ecumenical Patriarchate of Constantinople. However, most of the dioceses of the Metropolises of the New Lands are de facto administered as part of the Church of Greece for practical reasons, under an agreement between the churches of Athens and Constantinople. The primate of the Church of Greece is the archbishop of Athens and All Greece.

In Eastern Orthodoxy, autonomy designates a type of limited self-government of a church (group) toward its mother church. An autonomous church is self-governing in some aspects, which differentiates it from a non-autonomous church. The aspects on which the autonomous church is self-governing depends on the decision of the mother church. A church that is autonomous has its highest-ranking bishop, such as an archbishop or metropolitan, approved (or ordained) by the primate of the mother church.

Kephale (κεφαλή) means "head" in Greek, whereas nomos (νόμος) means "law". Hence, autocephalous (αὐτοκέφαλος) denotes self-headed, or a "head unto itself"; and autonomous denotes "self-legislated".

The Eastern Orthodox Church, officially the Orthodox Catholic Church and commonly known simply as the Orthodox Church, is a communion composed of up to seventeen separate autocephalous (self-governing) hierarchical churches that profess Eastern Orthodoxy and recognise each other as canonical (regular) Eastern Orthodox Christian churches.

Each constituent church is self-governing; its highest-ranking bishop called the primate (a patriarch, a metropolitan or an archbishop) reports to no higher authority. Each regional church is composed of constituent eparchies (or dioceses) ruled by bishops. Some autocephalous churches have given an eparchy or group of eparchies with varying degrees of autonomy (meaning they have limited self-government). Such autonomous churches maintain varying levels of dependence on their mother church, usually defined in a tomos or another document of autonomy. In many cases, autonomous churches are almost completely self-governing, with the mother church retaining only the right to appoint the highest-ranking bishop (often an archbishop or metropolitan) of the autonomous church.

The Macedonian Orthodox Church – Archdiocese of Ohrid (MOC-AO; Macedonian: Македонска православна црква – Охридска архиепископија, МПЦ-ОА, romanized: Makedonska pravoslavna crkva – Ohridska arhiepiskopija, MPC-OA), or simply the Macedonian Orthodox Church (MOC) or the Archdiocese of Ohrid (AO), is an autocephalous Eastern Orthodox church in North Macedonia. The Macedonian Orthodox Church claims ecclesiastical jurisdiction over North Macedonia, and is also represented in the Macedonian diaspora. The primate of the Macedonian Orthodox Church is Stefan Veljanovski, the Metropolitan of Skopje and Archbishop of Ohrid and Macedonia.

In 1959, the Holy Synod of the Serbian Orthodox Church granted autonomy to the Macedonian Orthodox Church in the then-Socialist Republic of Macedonia, as the restoration of the historic Archbishopric of Ohrid; the MOC was united with the Serbian Orthodox Church (SOC) as a part of the SOC. In 1967, on the bicentennial anniversary of the abolition of the Archbishopric of Ohrid, the Macedonian Holy Synod unilaterally announced its autocephaly from the Serbian Orthodox Church. The Serbian synod denounced the decision and condemned the clergy as schismatic. Thenceforth, the Macedonian Church had remained unrecognised by all mainstream Eastern Orthodox churches for 55 years.

The Armenian Apostolic Church (Armenian: Հայ Առաքելական Եկեղեցի, romanized: Hay Aṙaqelakan Ékełetsi) is the autocephalous national church of Armenia. Part of Oriental Orthodoxy, it is one of the most ancient Christian churches. The Armenian Apostolic Church uses the Armenian Rite. The Kingdom of Armenia was the first state in history to adopt Christianity as its official religion (under the Armenian Apostolic traditions) during the rule of King Tiridates III, of the Arsacid dynasty in the early 4th century.

According to tradition, the church originated in the missions of Apostles Bartholomew and Thaddeus (Jude) in the 1st century. St. Gregory the Illuminator was the first official primate of the church. It is sometimes referred to as the Armenian Apostolic Orthodox Church, Armenian Church or Armenian Gregorian Church.

The Patriarch of Alexandria is the archbishop of Alexandria, Egypt. Historically, this office has included the designation "pope" (etymologically "Father", like "Abbot").

The Alexandrian episcopate was revered as one of the three major episcopal sees (along with Rome and Antioch) before Constantinople and Jerusalem were granted similar status (in 381 and 451, respectively). Alexandria was elevated to de facto archiepiscopal status by the Councils of Alexandria, and this status was ratified by Canon Six of the First Council of Nicaea, which stipulated that all the Egyptian episcopal provinces were subject to the metropolitan see of Alexandria. In the sixth century, these five archbishops were formally granted the title of "patriarch" and were subsequently known as the Pentarchy.
