Which other churches is the Coptic Orthodox Church in communion with?

By CopticBot.ai (Coptic Space Inc.) · Last reviewed 2026-10-10

In the Coptic Orthodox Church, we are in full sacramental and theological communion with the other sister churches of the Oriental Orthodox family. This communion is rooted in our shared rejection of the Council of Chalcedon (451 AD) and our adherence to the Miaphysite Christology of St. Cyril of Alexandria, which confesses "One Nature of the Incarnate Word of God".

As a result, an Orthodox believer from any of these churches can receive the Holy Mysteries in a Coptic Church, and a Coptic Orthodox Christian can do the same in theirs.

The Oriental Orthodox Family

1. The Syriac Orthodox Church of Antioch: Led by the Patriarch of Antioch.
2. The Armenian Apostolic Church: Including both the Catholicosate of All Armenians (Etchmiadzin) and the Catholicosate of the Great House of Cilicia.
3. The Ethiopian Orthodox Tewahedo Church: Historically, this church was under the See of St. Mark but was granted autocephaly (independence) in the 20th century.
4. The Eritrean Orthodox Tewahedo Church: Granted autocephaly in the 1990s.
5. The Malankara Orthodox Syrian Church (India): Also known as the Indian Orthodox Church.

Important Distinctions Regarding Other Churches

• Eastern Orthodox (Chalcedonian): We are not yet in full sacramental communion with the Eastern Orthodox churches (such as the Greek, Russian, or Antiochian Orthodox). While significant progress was made during the Joint Commission meetings—such as the 1989 meeting at the Monastery of Saint Bishoi, where both sides agreed on the Christology of St. Cyril of Alexandria—the official lifting of anathemas and restoration of full communion have not yet been formally ratified by all synods. Therefore, we do not share the Eucharist with them.
• Roman Catholics: We are not in communion with the Roman Catholic Church. Despite historical dialogues and signed common declarations on Christology (such as the 1973 declaration between Pope Shenouda III and Pope Paul VI), major theological and dogmatic differences remain, including Papal Primacy/Infallibility, the Filioque clause, and several other later additions to their faith.
• Protestants: We are not in communion with any Protestant denominations. Protestantism is a later departure from the Apostolic Church, characterized by the rejection of the Holy Mysteries, the priesthood, and the intercession of the Saints and the Mother of God. Their understanding of salvation and the Eucharist is fundamentally different from the Orthodox Tradition.

As St. Cyril of Alexandria emphasized, the Eucharist cannot be given to heretics or schismatics because the "Body is One and must not be divided." To partake of the same Cup is to profess the same Faith. Therefore, we only share communion with those who uphold the fullness of the Orthodox Faith as it was handed down by the Apostles and the first three Ecumenical Councils (Nicaea, Constantinople, and Ephesus).
