The Armenian Apostolic Church, one of the oldest Christian denominations in the world, has a rich and complex history spanning over 1,700 years. With its roots in the 1st century AD, the church has played a significant role in shaping the spiritual, cultural, and national identity of the Armenian people. The church's history is deeply intertwined with the history of Armenia, a small country located in the South Caucasus region, and has been influenced by various empires and dynasties throughout the centuries.
The early history of the Armenian Apostolic Church is closely tied to the apostolic era, with tradition holding that the church was founded by two of Jesus' twelve apostles, Thaddeus and Bartholomew, in the 1st century AD. According to historical records, including the works of the 5th-century historian Agathangelos, the apostles preached in Armenia and converted the local population to Christianity. The church's early development was also influenced by the neighboring Christian communities, including the Syriac and Greek churches.
Establishment and Growth

The Armenian Apostolic Church was formally established in 301 AD, when Armenia became the first country to adopt Christianity as its official state religion. This event, known as the “Christianization of Armenia,” was facilitated by Saint Gregory the Illuminator, a Christian priest who converted the Armenian king, Tiridates III, to Christianity. The church’s growth and development were rapid, with the establishment of the first Armenian cathedral, the Etchmiadzin Cathedral, in 301 AD, which remains the spiritual center of the church to this day.
The church's early history was marked by periods of persecution and martyrdom, particularly during the Roman and Persian empires. However, the church continued to thrive, and by the 5th century, it had developed a distinct theological and liturgical tradition. The Armenian Apostolic Church played a significant role in the development of Christianity in the region, with Armenian missionaries and theologians contributing to the spread of Christianity to neighboring countries, including Georgia and Albania.
Doctrine and Practice
The Armenian Apostolic Church is an Oriental Orthodox church, which means that it is part of the broader Orthodox Christian tradition. The church’s doctrine and practice are based on the teachings of the apostles and the early Christian fathers, with a strong emphasis on the importance of tradition and the authority of the Bible. The church’s liturgy and worship are characterized by a rich and complex ritual, which includes the use of ancient Armenian hymns, prayers, and sacraments.
The church's doctrine is based on the Nicene Creed, which was formulated in 325 AD, and the church recognizes the authority of the first three ecumenical councils, including the Council of Nicaea, the Council of Constantinople, and the Council of Ephesus. The church also places a strong emphasis on the importance of monasticism and the role of monasteries in preserving and transmitting Christian tradition and culture.
