A catholicos (plural: catholicoi) is the head of certain churches in some Eastern Christian traditions. The title implies autocephaly and, in some cases, it is the title of the head of an autonomous church. The word comes from ancient Greekκαθολικός (pl. καθολικοί), derived from καθ' ὅλου (kath'olou, "generally") from κατά (kata, "down") and ὅλος (holos, "whole"), meaning "concerning the whole, universal, general"; it originally designated a financial or civil office in the Roman Empire.[1]
The earliest ecclesiastical use of the title catholicos was by the Bishop of Etchmiadzin, head of the Armenian Apostolic Church, in the 4th century[1] while still under the Patriarchate of Antioch.[4] Among the Armenians, catholicos was originally a simple title for the principal bishop of the country; he was subordinate to the See of Caesarea in Cappadocia.[4]
At the beginning of the fourth century, Albania and Georgia (Iberia) were converted to Christianity, and the principal bishop of each of these countries bore the title of catholicos, although neither of them was autocephalous. They followed the Armenians in rejecting the Council of Chalcedon. At the end of the sixth or beginning of the seventh century, the Georgian catholicos asserted his independence and accepted Eastern Orthodoxy. Henceforward the Georgian Church underwent the same evolutions as the Greek. In 1783 Georgia was forced to abolish the office of its catholicos, and place itself under the Most Holy Synod of Russia, to which country it was united politically in 1801. The Albanian catholicos remained loyal to the Armenian Church, with the exception of a brief schism towards the end of the sixth century. Shortly afterwards, Albania was assimilated partly with Armenia and partly with Georgia. There is no mention of any catholicos in Albania after the seventh century. It is asserted by some that the head of the Abyssinian Church, the abuna, also bears the title of catholicos, but, although this name may have been applied to him by analogy, there is, to our[who?] knowledge, no authority for asserting that this title is used by the Abyssinian Church itself.[4]
As of September 13, 2021[update], Mar Awa III is the catholicos-patriarch of the Assyrian Church of the East. One of the oldest Christian churches, it is a modern successor of the historical Church of the East. It traces its origins to the See of Seleucia-Ctesiphon in central Mesopotamia, which tradition holds was founded by Saint Thomas the Apostle (Tooma Shlikha) as well as Saint Mari and Saint Addai in AD 33 as asserted in the Doctrine of Addai.
It is one of the three churches of the East that hold themselves distinct from Oriental and Eastern Orthodoxy. In India, it is more often called the Chaldean Syrian Church. In the West it is often called the Nestorian Church, due to its alleged associations with Nestorianism, though the church itself considers the term pejorative and argues that this association is incorrect. The church declares that no other church has suffered as many martyrdoms as the Assyrian Church of the East.[citation needed]
The founders of Assyrian theology were Diodorus of Tarsus and Theodore of Mopsuestia, who taught at Antioch. The normative Christology of the Assyrian church was written by Babai the Great (551–628) and is clearly distinct from the accusations directed toward Nestorius: his main Christological work is called the 'Book of the Union', and in it Babai teaches that the two qnome (essences, or hypostases) are unmingled but everlastingly united in the one parsopa (personality) of Christ.[citation needed]
In the Armenian Church there are two catholicoi: the supreme catholicos of Etchmiadzin and the catholicos of Cilicia. The Catholicos of Etchmiadzin presides over the Supreme Spiritual Council of the Armenian Apostolic Church and is the head of the world's 7 million Armenian Apostolic Christians. The primacy of honour of the Catholicosate of Etchmiadzin has always been recognized by the Catholicosate of Cilicia.

Karekin II is the current catholicos of the Armenian Apostolic Church.
Aram I is the present catholicos of the Great House of Cilicia.
Until the 19th century, there were also two other high-ranking Armenian clergymen who held the title of catholicos: the Catholicos of Albania (also known as the Catholicos of Gandzasar) and the Catholicos of Aghtamar.[7]
Syriac Orthodox Church
In the seventh century, the Syriac Orthodox Christians who lived in Persia began using the title for its catholicos / maphrian, who was originally the head of the Syriac Orthodox Christian community in Persia. This office ranked second in the Syriac Orthodox church hierarchy after the Syriac Orthodox Patriarch of Antioch, until it was abolished in 1860 and reinstated in the India of the East on 1964.
In 1959, the Coptic Orthodox Church of Alexandria granted autocephaly to the Ethiopian Orthodox Tewahedo Church. Abuna Basilios was consecrated the first patriarch-catholicos of the Ethiopian Church by the Coptic Pope Cyril VI at St. Mark's Cathedral in Cairo on 28 June 1959. The title is "Patriarch and Catholicos of Ethiopia, Ichege of the See of St. Tekle Haymanot, Archbishop of Axum".
