I. Origins
Foundational Identities
The Armenian Apostolic Church and the Coptic Orthodox Church of Alexandria are two of the oldest Christian institutions in existence, and their parallel histories intertwine across nearly two millennia of shared theology, shared persecution, and shared witness.
The Armenian Apostolic Church traces its origins to the missions of Apostles Bartholomew and Thaddeus in the first century AD. St. Gregory the Illuminator was its first official primate. The church's formative moment came in the early fourth century: the Kingdom of Armenia became the first state in history to adopt Christianity as its official religion in 301 AD. The spiritual leader of the church, the Catholicos of All Armenians, resides at the Mother See of Holy Etchmiadzin, near Yerevan, Armenia — a cathedral considered the oldest state-built Christian cathedral in the world.
The Coptic Church traces its founding to Saint Mark the Evangelist, author of the second Gospel, who according to tradition arrived in Alexandria around AD 42 and was eventually martyred there. The term "Copt" carries its own history: the people of Egypt before the Arab conquest in the seventh century identified themselves in Greek as Aigyptios, from which the Arabic qibṭ and the Westernized "Copt" derive. When Egyptian Muslims later ceased to call themselves by this name, it became the distinctive name of the Christian minority.
Shared identity
Both churches carry an identity rooted not just in doctrine but in civilization itself — the Armenian church as the guardian of a national people, the Coptic church as the custodian of ancient Egypt's Christian soul.
II. Theology
The Rupture at Chalcedon (451 AD) & the Birth of the Oriental Orthodox Family
The single most important event in understanding the relationship between these two churches — and indeed the entire Oriental Orthodox family — is the Council of Chalcedon in 451 AD.
The Council rejected what it called monophysite doctrine and affirmed both Christ's human and divine natures. The Coptic Church became one of several Eastern churches that refused the Chalcedonian Christological language. Rather than accepting the label "monophysite," both churches adopted the position of miaphysitism: following Cyril of Alexandria, they teach that Christ has "one united nature" — not one nature in the sense of denying his humanity, but one united divine-human nature.
The Armenian Church officially severed ties with Rome and Constantinople in 610 AD, during the Third Council of Dvin, where the Chalcedonian dyophysite formula was rejected.
There are six churches known as the Old Oriental Orthodoxy or Non-Chalcedonian Churches:
- Syriac Orthodox Church
- Coptic Orthodox Church of Alexandria
- Ethiopian Orthodox Tewahedo Church
- Eritrean Orthodox Tewahedo Church
- Malankara Orthodox Syrian Church (India)
- Armenian Apostolic Church
These six are united by their acceptance of only the first three ecumenical councils — Nicaea (325), Constantinople (381), and Ephesus (431) — and their rejection of Chalcedon.
20th-century reassessment
By the 20th century, the Chalcedonian schism was no longer seen with the same relevance. Several meetings between Roman Catholicism and Oriental Orthodoxy yielded reconciliation statements acknowledging that "the confusions and schisms arose only because of differences in terminology and culture" — not in the substance of faith.
III. Liturgical Memory
Shared Saints & the Formal Recognition of Unity
One of the most intimate expressions of the bond between the Coptic and Armenian churches is the liturgical veneration each extends to the other's saints. This is not merely diplomatic — it speaks to a deep theological solidarity maintained across centuries.
In its liturgies, the Coptic Orthodox Church mentions St. Gregory the Armenian (the Illuminator) and reads the biography of St. Hripsima in the Synaxarium. St. Hripsima was one of the Armenian women martyred under King Tiridates III before his conversion by Gregory — her story is woven into the very founding narrative of Armenian Christianity.
"The Coptic Church honors Saint Gregory the Armenian and Saint Hripsime the Armenian in its prayer services."
— Pope Tawadros II, 2024That the Coptic church enshrines her memory in its daily prayer cycle is a remarkable act of communion across space and time — two ancient churches binding their liturgical memory together, across continents and centuries.
IV. Modern History
The First Modern Gathering: Addis Ababa 1965
The modern chapter of formal institutional relations between the Oriental Orthodox churches opened in a landmark gathering in Ethiopia. In 1965, the heads of the Oriental Orthodox Churches officially met for the first time, at the invitation of Emperor Haile Selassie in Addis Ababa.
- Pope Cyril VI of the Coptic Church
- Mor Ignatius Jacob III of the Syriac Church
- Catholicos Vazgen I of the Armenian Orthodox Church of Etchmiadzin
- Catholicos Khoren I of the Armenian Orthodox Church of Cilicia
This gathering was the first time the heads of these ancient churches sat together in conciliar solidarity. The Catholicosate of Cilicia was instrumental in initiating the annual official meetings of the Heads of the Oriental Orthodox Churches in the Middle East, which began in 1996.
V. Joint Declaration
The 1998 Cairo Declaration: A Landmark Document
The most significant formal bilateral event between the two churches in modern history came in January 1998, when Catholicos Karekin I of All Armenians visited Egypt. The two leaders — Karekin I and Pope Shenouda III — met in Cairo from the 14th to the 18th of January, praying together and deliberating on their common calling in the service of Christ.
Key provisions of the Joint Declaration
The declaration reaffirmed the unity of their Christian faith maintained through past centuries, based on the Holy Scriptures, early Church Tradition, and the first three Ecumenical Councils of Nicaea (325), Constantinople (381), and Ephesus (431).
It called on diocesan metropolitans, bishops, parish priests and lay people in both Egypt and Armenia, as well as the worldwide diaspora, to advance mutual cooperation — particularly in service to the young generation.
It encouraged greater collaboration in theological education and recommended the exchange of students and professors between theological schools.
The two patriarchs explicitly prayed for peace in Nagorno-Karabagh, linking ecclesiastical solidarity to the political suffering of the Armenian people.
Pope Shenouda III referenced his visits to Armenia in 1995, speaking about the historical relations between the two churches and their full unity in faith.
VI. Ongoing Institutions
Annual Meetings of Oriental Orthodox Heads (1996–Present)
In 1995, Catholicos Aram I was elected and recognized the importance of reviving inter-Oriental Orthodox meetings. He reached out to Pope Shenouda III and Mor Ignatius Zakka I Iwas of the Syriac Church. With shared spiritual counsel, the first modern gathering of Oriental Orthodox leaders in the Middle East was held in 1996.
This annual summit — currently hosted under the care of Pope Tawadros II, with the participation of the Armenian and Syriac patriarchs — continues to this day and represents the most active ongoing institutional expression of the Oriental Orthodox family's unity.
Both the Armenian and Coptic churches participate together in the broadest framework of global Christian ecumenism through the World Council of Churches. The Ethiopian, Coptic, and Indian churches have been full members since its inauguration in Amsterdam in 1948; the Armenian church was admitted in Paris in 1962.
VII. Ecumenism
Shared Participation in the Catholic–Oriental Orthodox Dialogue
Beyond their intra-Oriental communion, both the Armenian and Coptic churches participate jointly in the formal international dialogue with the Roman Catholic Church. Founded in 2003, the Joint International Commission for Theological Dialogue between the Catholic Church and the Oriental Orthodox Churches includes representatives of all six Oriental Orthodox traditions.
The twentieth meeting of this commission took place in Rome in January 2024, chaired jointly by Cardinal Kurt Koch and Coptic Orthodox Bishop Kyrillos. Delegates included hierarchs and scholars from both the Armenian Apostolic Church and the Coptic Orthodox Church.
Significance
The commission has progressively established that many differences between Rome and the Oriental Orthodox are differences of terminology rather than substance — a conclusion that simultaneously deepens the known unity between the Oriental Orthodox churches themselves.
VIII. Solidarity
Twentieth-Century Solidarity: The Genocide & Coptic Witness
The Armenian Genocide of 1915 forms a defining dimension of the relationship between the two communities. Egypt's Coptic-majority society was a place of refuge for Armenians fleeing the Ottoman massacres, and the Coptic Church has shown explicit solidarity with Armenian memory.
In 2015, for the centennial of the genocide, Pope Tawadros II traveled to Armenia to participate in the centennial commemoration events. Earlier that year, he visited Beirut to participate in the prayers for the sanctification of the Holy Chrism (Myron Oil) by the Armenian Orthodox Church, at the invitation of Catholicos Aram I. During his stay, he visited the Armenian Genocide Orphans' Aram Bezikian Museum and acknowledged the Armenian Genocide.
"The Coptic Church's participation in such ceremonies is an expression of Christian love held in the heart toward Jesus Christ."
— Pope Tawadros II, Beirut, 2015IX. Present Day
The Relationship Today
Today the relationship between the two churches is warm and institutionally active. Pope Tawadros II has spoken repeatedly of his personal friendship with both Catholicos Karekin II of Etchmiadzin and Catholicos Aram I of Cilicia.
During a meeting with Armenian Prime Minister Nikol Pashinyan in Cairo in March 2024, Pope Tawadros II praised the relations between the Coptic Orthodox and Armenian Apostolic churches, noting that "Egypt is a country that has always opened its doors for Armenians to live and integrate into its society."
In November 2025, an international academic conference at Holy Cross School of Theology brought together hierarchs, scholars, and faithful from both Eastern and Oriental Orthodox traditions — including Coptic, Armenian, Syrian, Ethiopian, and Indian delegations — in an ongoing effort to affirm and act upon theological agreements developed over recent decades.
