Tradition · 301

Armenian Apostolic

The national church of Armenia, one of the Oriental Orthodox churches, led by the Catholicos of All Armenians at Etchmiadzin.

History

Roots

Armenian tradition traces its faith to the apostles Thaddeus and Bartholomew, which is where the name “Apostolic” comes from. The church as an institution begins with Gregory the Illuminator. According to the History attributed to Agathangelos (5th century, Thomson translation, Archive.org), King Tiridates III imprisoned Gregory in a pit for years, fell into madness, and was healed through Gregory’s prayers. The king was baptised and made Christianity the religion of his kingdom, traditionally dated 301, though many historians prefer a date closer to 314 (summary, secondary). Either way, Armenia was among the first states to adopt Christianity officially. Gregory was consecrated bishop at Caesarea in Cappadocia, and the cathedral of Etchmiadzin (“the Only-Begotten descended”) was built on the site of his vision.

The second founding moment was linguistic. Around 405 the monk Mesrop Mashtots created an Armenian alphabet, and he and Catholicos Sahak translated the Bible and the liturgy into Armenian. His disciple Koriun tells the story in The Life of Mashtots (Norehad translation, 1964, Archive.org). A literature of translation and history followed, and the church became the main carrier of Armenian identity, a role it has kept under Persian, Arab, Byzantine, Mongol, Ottoman, Russian and Soviet rule.

Causes of the break with Chalcedon

In 451 Armenia fought the Persians at the Battle of Avarayr (summary, secondary), a defeat remembered as a martyrdom for the faith. The same year, the Council of Chalcedon met without any Armenian bishops. The Armenian church had received the Council of Ephesus (431) and the Christology of Cyril of Alexandria, and when Chalcedon’s definition of Christ “in two natures” reached Armenia, it was read as a concession to Nestorius.

The rejection came in stages. The First Council of Dvin (506) accepted Emperor Zeno’s Henotikon, a compromise that condemned Nestorius without endorsing Chalcedon (summary, secondary). The Second Council of Dvin (554/555) formally declined Chalcedon’s decrees, and its date became the starting point of the Armenian church calendar (summary, secondary). Politics mattered too. Armenia lay between Byzantium and Persia, and distance from Constantinople’s council was also distance from Constantinople’s emperor. From then on Armenia belonged with the Copts and Syrians in what is now called the Oriental Orthodox family, holding to Miaphysitism.

Influence and later history

The break was never treated as final on either side. Repeated union talks with Byzantium failed. The most serious came under Catholicos Nerses IV Shnorhali (“the Gracious,” 1166–1173), who wrote a conciliatory profession of faith for Emperor Manuel I Komnenos. The emperor’s terms, including an imperial voice in choosing future catholicoi, proved unacceptable (summary, secondary). Nerses is still honoured as a hymn writer and as a model of ecumenical patience.

The seat of the catholicos wandered with Armenian political fortunes, finally settling in Sis in the Armenian kingdom of Cilicia in 1293. In 1441 a Catholicos of All Armenians was elected again at Etchmiadzin while the Cilician line continued at Sis. The result is the church’s present structure: two catholicosates, Etchmiadzin and the Holy See of Cilicia (in Antelias, Lebanon, since 1930), plus the Armenian Patriarchates of Jerusalem and Constantinople, all in one communion (summary, secondary). Contact with Latin crusaders in Cilicia also produced a Catholic party. It became the Armenian Catholic Church, in union with Rome since 1742 (summary, secondary).

The twentieth century nearly destroyed the church. The Armenian genocide of 1915–1923 killed most of the clergy in Anatolia and emptied its dioceses. Soviet rule then closed churches and persecuted clergy in Armenia itself. In April 2015 the church canonised the victims of the genocide as martyrs, in what is often described as the largest canonisation in history. Since independence in 1991 the church has rebuilt in Armenia and serves a diaspora larger than the population of the republic.

Key ideas and contributors

One incarnate nature. The Armenian church confesses, with Cyril, “one nature of God the Word incarnate.” It insists this is not a mixing of divinity and humanity, and it condemns Eutyches as firmly as Nestorius. The point is that the Word made flesh is one subject, and splitting his acts between two natures seemed to Armenian theologians to divide Christ. In 1996 Pope John Paul II and Catholicos Karekin I signed a Common Declaration confessing that Christ’s “divinity is united to His humanity in the Person of the Only-begotten Son of God,” a formula both churches could accept. See Christ and Chalcedonian Christology for the wider dispute.

Three councils. The church receives Nicaea (325), Constantinople (381) and Ephesus (431) as ecumenical, and no later council. Its theology rests on those councils, the fathers, and its own Holy Tradition.

A national church with bishops. The church has an Episcopal Polity under the Catholicos of All Armenians, with a strong place for lay delegates in electing the catholicos and managing parishes. Its clergy include married parish priests and celibate vardapets (doctor-monks) from whom bishops are drawn.

Liturgy and practice. The Divine Liturgy is celebrated in classical Armenian (grabar). The church uses unleavened bread and wine without water in the chalice, a practice that set it apart from both Greeks and Syrians. It keeps the ancient custom of celebrating Christ’s birth and baptism together on 6 January. Its Trisagion includes the phrase “who was crucified for us,” a Miaphysite marker. The Sacraments are the seven familiar to the Orthodox, with Infant Baptism followed at once by chrismation and communion.

Writers. Gregory of Narek (c. 950–1003/1011) wrote the Book of Lamentations, 95 prayers that remain the best-loved book of Armenian devotion. Pope Francis declared him a Doctor of the Church in 2015 (summary, secondary). Nerses Shnorhali’s hymns and Mashtots’s translations round out the classic canon.

Key controversies

Was Chalcedon heresy or misunderstanding? For centuries Byzantine writers called the Armenians Monophysites, and Armenians accused Chalcedon of Nestorianism. Modern dialogue has largely concluded that the two sides meant the same faith in different words. The 1996 declaration says that “linguistic, cultural and political factors have immensely contributed towards the theological divergences.” Critics on both sides doubt this. Some Eastern Orthodox and Catholic theologians hold that Chalcedon’s “in two natures” is not negotiable, and some Armenian clergy see ecumenical statements as erosion of a confession paid for in blood.

Unmixed wine and other rites. The Byzantine Council in Trullo (692) condemned the Armenian practice of offering wine without water (canon 32), and the Latin Council of Florence (1439) issued a decree for the Armenians requiring the mixed chalice (unverified as to exact wording). Armenian writers defended their custom as apostolic. The dispute shows how liturgy became a badge of identity on all sides.

Union with Rome. The Armenian Catholic Church is a sore point. The Apostolic church long viewed it as a product of proselytism that divided Armenian communities, especially in the Ottoman Empire, where Armenian Catholics faced persecution until a declaration of religious liberty in 1830 (Catholic Encyclopedia, “Armenia”, secondary). Relations have warmed since the 1990s, with papal visits to Armenia in 2001 and 2016 and Pope Francis’s 2015 homily on the genocide, which quoted the 2001 declaration of John Paul II and Karekin II calling it “the first genocide of the twentieth century”.

The diaspora split. On 24 December 1933 Archbishop Levon Tourian was murdered in a New York church by members of the Armenian Revolutionary Federation, who saw him as too accommodating to Soviet Armenia, where Etchmiadzin lay (summary, secondary). The quarrel divided American parishes between Etchmiadzin and, from 1957, the Holy See of Cilicia. The two jurisdictions still exist side by side in the United States, holding the same faith under different catholicoi.

Church and state in Armenia. Since 2025 the church has been in open conflict with the government of Prime Minister Nikol Pashinyan. Pashinyan publicly demanded the resignation of Catholicos Karekin II, several senior clergy were arrested, and in 2026 the catholicos himself faced criminal proceedings, which the church calls politically motivated (summary, secondary). The case turns on an old question for a national church: whether it answers to the nation’s government or stands apart from it.

What remains unresolved

Doctrinally, the gap with Chalcedonian churches is now narrow on paper. Theologians on both sides largely agree that Armenian Miaphysitism and Chalcedonian dyophysitism describe one Christ. What keeps the churches apart is the status of the councils after Ephesus, questions of authority, and fifteen centuries of separate identity. Inside Armenia, the harder question is practical: how a church that carried a nation through conquest and genocide relates to that nation’s own democratic state.
