Greek Orthodox Church of Antioch in the context of "See of Antioch"

Antiochian Greek Christians (also known as Rūm) are an ethnoreligious Eastern Christian group native to the Levant. The majority of its members identify as Arab, though some of the members reject the Arab label and instead identify as Greek. They are either members of the Greek Orthodox Church of Antioch or the Melkite Greek Catholic Church, and they have ancient roots in what is now Syria, Lebanon, Israel, Palestine, Jordan, the southern Turkish province of Hatay, which includes the city of Antakya (ancient Antioch—one of the holiest cities in Eastern Christianity). Many of their descendants now live in the global Near Eastern Christian diaspora. They primarily speak Levantine Arabic, with Maaloula near Damascus being one of the few places where a Western Aramaic dialect is still spoken.

The patriarch of Antioch is one of the Eastern Orthodox patriarchs, the leader of the autocephalous Greek Orthodox Church of Antioch. The term "Greek" does not refer to ethnic origin; the majority of these patriarchs were not ethnic Greeks, but rather Hellenized Arabs, Arameans, Assyrians, and other Levantines who spoke Greek and adopted a Hellenic identity. It refers to the fact that this church follows the Chalcedonian Orthodoxy associated with the (Greek-speaking) Byzantine Empire. Since 518, there have been two patriarchs of Antioch who call themselves Orthodox: the Chalcedonian ones listed here, and the non-Chalcedonian Syriac Orthodox patriarchs of Antioch.

The Maronite Church (Arabic: الكنيسة المارونية‎; Syriac: ܥܕܬܐ ܣܘܪܝܝܬܐ ܡܪܘܢܝܬܐ) is an Eastern Catholic sui iuris particular church in full communion with the pope and the worldwide Catholic Church, with self-governance under the Code of Canons of the Eastern Churches. The head of the Maronite Church is Patriarch Bechara Boutros al-Rahi, who was elected in March 2011 following the resignation of Patriarch Nasrallah Boutros Sfeir. The seat of the Maronite Patriarchate is in Bkerké, northeast of Beirut, Lebanon. Officially known as the Antiochene Syriac Maronite Church (Arabic: الكنيسة الأنطاكية السريانية المارونية; Syriac: ܥܹܕܬܵܐ ܣܘܪܝܝܐ ܡܪܘܝܝܐ ܐܢܛܝܘܟܝܐ), it is part of Syriac Christianity by liturgy and tradition.

The early development of the Maronite Church can be divided into three periods, from the 4th to the 7th centuries. A congregation movement, with Saint Maron from the Taurus Mountains as an inspirational leader and patron saint, marked the first period. The second began with the establishment of the Monastery of Saint Maroun on the Orontes, built after the Council of Chalcedon to defend the doctrines of the council. This monastery was described as the "greatest monastery" in the region of Syria Secunda, with more than 300 hermitages around it, according to ancient records. After 518, the monastery de facto administered many parishes in Syria Prima, Cole Syria and Phoenicia. The third period was when Sede Vacante followed the Islamic conquest of the region and bishops of the Saint Maron Monastery elected John Maron as Patriarch circa 685 AD, according to Maronite tradition. The Greek Orthodox Church of Antioch reestablished their patriarchate in 751 AD. Other centers of historical importance include Kfarhay, Yanouh, Mayfouq, and the Qadisha Valley.

The Syriac Orthodox patriarch of Antioch and All the East is the head of the Syriac Orthodox Church. According to tradition, the patriarchate of Antioch was established by Saint Peter in the 1st century AD, but split into two separate lines of patriarchs after the deposition of Patriarch Severus of Antioch in 518 over the issue of the Council of Chalcedon of 451. The non-Chalcedonian supporters of Severus went on to form what is now known as the Syriac Orthodox Church, whilst the Chalcedonians developed the church now known as the Greek Orthodox Church of Antioch.

The Syriac Orthodox Church underwent schism in the medieval era, first, after the death of Patriarch Philoxenus I Nemrud in 1292 with the formation of separate patriarchates of Mardin and Melitene, and again in 1364 due to the emergence of a patriarchate of Tur Abdin. Unity was restored to the church gradually as the patriarchate at Melitene came to an end in c. 1360, and the patriarchate of Mardin lapsed after its patriarch Ignatius Behnam Hadloyo was acknowledged as patriarch of Antioch in 1445. A line of patriarchs in communion with the Catholic Church split permanently in 1782, and thus formed the Syriac Catholic Church.

The office was established with the election of Ignatius Andrew Akijan in 1662 as patriarch of Antioch, thereby creating a separate line of patriarchs in full communion with the Catholic Church, in opposition to the Syriac Orthodox Church. Despite initial success, after the death of Ignatius Gregory Peter VI Shahbaddin in 1701 or 1702, most Syriac Catholics returned to the Syriac Orthodox Church, and the office lay vacant until the election of Ignatius Michael III Jarweh in 1782, from which a permanent line of Syriac Catholic patriarchs sprang.
