Autocephalous Churches
| # | Church | Seat | Tradition | Status / Notes |
|---|---|---|---|---|
| 1 | Coptic Orthodox ChurchCoptic Orthodox Patriarchate of Alexandria | Cairo (officially Alexandria) | Alexandrian (Coptic) | Largest Oriental Orthodox church worldwide (est. 10–15 million faithful). The Coptic Pope holds a primacy of honor among Oriental Orthodox churches. Apostolic foundation attributed to St. Mark the Evangelist. |
| 2 | Ethiopian Orthodox Tewahedo ChurchPatriarchate
Note:
In February 2023, a major internal crisis erupted when three bishops of the Oromia region declared themselves an alternative Holy Synod and began ordaining bishops without authorization. Patriarch Abune Mathias condemned the move. With the mediation of Prime Minister Abiy Ahmed, an agreement was reached, but its implementation remains disputed. The Ethiopian Orthodox Tewahedo Church also faces a separate schism in the Tigray region (see Section 3 below).
|
Addis Ababa | Ethiopian (Ge’ez) | Largest Oriental Orthodox church in a single country (est. 36–50 million). Was a dependency of the Coptic Patriarchate until 1959, when it was granted autocephaly by Pope Cyril VI of Alexandria. |
| 3 | Eritrean Orthodox Tewahedo ChurchPatriarchate
Note:
In 2006, the Eritrean government forced the removal of Patriarch Abune Antonios, who was placed under house arrest, where he remained until his death in 2022. His replacement, Abune Dioskoros, was not recognized as legitimate by the Coptic Church or by many Eritrean faithful. In 2023–2024, Coptic Pope Tawadros II conducted mediation efforts. The canonical situation remains sensitive due to continuing government interference.
|
Asmara | Eritrean (Ge’ez) | Became autocephalous in 1993 following Eritrean independence, with the consent of the Coptic Patriarchate. Approximately 2–3 million faithful. |
| 4 | Syriac Orthodox ChurchSyriac Orthodox Patriarchate of Antioch and All the East | Damascus (patriarchal residence in recent decades has been in Lebanon, with offices also in Damascus) | Antiochene (West Syriac) | Est. 2–5 million worldwide (including diaspora). Claims direct apostolic succession from the See of Antioch. The patriarch bears the traditional name Ignatius. Significant diaspora in Europe, the Americas, and India (through the Malankara connection). |
| 5 | Armenian Apostolic ChurchCatholicosate
(1) Mother See of Holy Etchmiadzin — Supreme Catholicosate; primacy of honor and jurisdiction over most Armenian faithful worldwide.
(2) Catholicosate of the Great House of Cilicia — Seat: Antelias, Lebanon. Historically autonomous; has its own synod and jurisdiction over certain dioceses, mainly in Lebanon, Syria, Cyprus, and parts of the diaspora. (3) Armenian Patriarchate of Jerusalem — Jurisdiction over the Armenian community in the Holy Land. (4) Armenian Patriarchate of Constantinople — Jurisdiction over Armenians in Turkey.
Note on Etchmiadzin–Cilicia relations:
Tensions have periodically arisen between Etchmiadzin and Cilicia regarding the extent of Cilicia’s autonomy. In 1956, a jurisdictional dispute led the Catholicosate of Cilicia to assert broader independence, linked in part to Cold War-era politics (Etchmiadzin being under Soviet influence). The two catholicosates are in full communion but maintain separate administrations, and disputes over diaspora jurisdictions continue. The two patriarchates recognize the primacy of Etchmiadzin.
|
Etchmiadzin (Mother See of Holy Etchmiadzin), Armenia | Armenian | Est. 6–9 million worldwide. Organized into two catholicosates and two patriarchates (see details at left). |
| 6 | Malankara Orthodox Syrian ChurchIndian Orthodox Church — Catholicosate
Status disputed:
The Malankara Orthodox Syrian Church considers itself autocephalous, governed by its own Catholicos of the East and Malankara Metropolitan. It traces its autocephaly to 1912, when Catholicos Baselios Paulose I was consecrated as an independent head. The Syriac Orthodox Patriarchate of Antioch, however, considers the Malankara Church to be an autonomous church under its spiritual jurisdiction, and maintains a parallel structure in India — the Jacobite Syrian Christian Church (see #7 below). This dispute has produced decades of litigation in Indian courts, notably a 2017 Supreme Court of India ruling that favored the Malankara Orthodox Syrian Church’s control over disputed parishes. The Jacobite Syrian Church does not accept this ruling as resolving the ecclesiological question. The two communities share the same West Syriac liturgical tradition but remain divided in governance.

Kottayam (Devalokam), Kerala, India | Indian (West Syriac / Malankara) | Est. 2.5–3 million, primarily in Kerala. |

↳ Mother Church: Syriac Orthodox Patriarchate of Antioch |
Puthencruz, Kerala, India | Indian (West Syriac / Malankara) | The Jacobite Syrian Christian Church considers itself the legitimate continuation of the undivided Malankara Syrian Christian community in full obedience to the Syriac Patriarch of Antioch. It is governed by a Malankara Metropolitan appointed or approved by the patriarch. Est. 1–2 million faithful. See the note under #6 for the ongoing dispute with the Malankara Orthodox Syrian Church. |

| 8 | Tigrayan Orthodox Tewahedo Church (TOTC)Self-declared Patriarchate
Not recognized:
The Ethiopian Orthodox Tewahedo Church considers this separation illegitimate and has excommunicated the bishops involved. No other Oriental Orthodox church has recognized the TOTC.
|
Mekelle, Tigray, Ethiopia | Ethiopian (Ge’ez / Tigrinya) | On 7 May 2021, in the wake of the Tigray War (2020–2022), four archbishops in Tigray announced the formation of a new and independent structure — the “See of Selama Kessate Birhan” — accusing the Ethiopian Orthodox Tewahedo Church’s Holy Synod of having aligned itself with the federal government during the conflict and of having failed to protect Tigrayan churches and monasteries from destruction. On 23 October 2024, following a three-day meeting, the TOTC formally established its own Holy Synod. The TOTC has dioceses in Tigray and in the diaspora (notably the United States). The proportion of Tigrayan faithful who adhere to the TOTC rather than to the Ethiopian patriarchate is not precisely known. |

Churches of a Distinct Tradition (for reference)

|---|---|---|---|---|
| 9 | Assyrian Church of the EastPatriarchate
Note:
The Assyrian Church of the East is sometimes listed alongside Oriental Orthodox churches, but it belongs to a distinct tradition: it did not accept the Council of Ephesus (431) and its Christological definitions, whereas the Oriental Orthodox accept Ephesus but reject the Council of Chalcedon (451). The Assyrian Church professes a dyophysite Christology and is not in communion with the Oriental Orthodox churches.
|
Erbil, Iraq (historically Seleucia-Ctesiphon) | East Syriac | Est. 0.4–1 million faithful worldwide, with communities in Iraq, Iran, India (notably Kerala), and the diaspora (United States, Australia, Europe). |
| 10 | Ancient Church of the EastPatriarchate
Note:
Split from the Assyrian Church of the East in 1964 (formalized 1968) over the decision by Patriarch Shimun XXI to adopt the Gregorian calendar and introduce other reforms. Shares the same East Syriac liturgical tradition and dyophysite theology. Also not in communion with the Oriental Orthodox churches.
|
Baghdad, Iraq | East Syriac | A small community, est. under 100,000 faithful. |
Notes
- The expression “Oriental Orthodox” (or “pre-Chalcedonian”) designates churches that did not accept the Christological definition of the Council of Chalcedon (451). These churches profess a Miaphysite Christology (one united nature of Christ, divine and human), which they distinguish from the Monophysite position condemned at Chalcedon. Since the mid-20th century, ecumenical dialogues have established that the difference with Chalcedonian (Eastern Orthodox and Catholic) Christology is largely terminological rather than substantive.
- The Armenian Apostolic Church is sometimes classified separately as a “non-Chalcedonian” church with its own distinct theological tradition, since the Armenian rejection of Chalcedon was in part due to historical and political circumstances (absence from the council) rather than solely theological disagreement.
- All Oriental Orthodox churches are in full communion with one another. Regular pan-Oriental Orthodox meetings are convened, though no formal unified structure (such as an equivalent to the pan-Orthodox synaxis in the Eastern Orthodox world) exists.
- The Assyrian Church of the East and the Ancient Church of the East (Section 4) are included for reference, as they are frequently confused with the Oriental Orthodox family. They belong to the “Church of the East” tradition and are not part of the Oriental Orthodox communion.
- Faithful numbers are approximate and vary significantly depending on sources.
