Religion

Armenia was the first nation to adopt Christianity as a state religion, an event traditionally dated to AD 301.

The predominant religion in Armenia is Christianity. Its roots go back to the 1st century AD, when it was founded by two of Jesus' twelve apostles – Thaddaeus and Bartholomew – who preached Christianity in Armenia between AD 40–60.

Over 93% of Christians in Armenia belong to the Armenian Apostolic Church, which is in communion only with the churches comprising Oriental Orthodoxy —of which it is itself a member.

The Catholic Church maintains jurisdictions of both the Latin Church and Armenian Catholic Church in Armenia. Of note are the Mechitarists (also spelled "Mekhitarists" Armenian: Մխիթարեան), a congregation of Benedictine monks in the Armenian Catholic Church, founded in 1712 by Mekhitar of Sebaste. They are best known for their series of scholarly publications of ancient Armenian versions of otherwise lost ancient Greek texts.

The Armenian Evangelical Church has several thousand members throughout the country.

Other Christian denominations in Armenia are the Pentecostal branches of Protestant community such as the Word of Life, the Armenian Brotherhood Church, the Baptists (which are known as one of the oldest existing denominations in Armenia, and were permitted by the authorities of the Soviet Union), and Presbyterians.

Armenia is also home to a Russian community of Molokans which practice a form of Spiritual Christianity originated from the Russian Orthodox Church.

The Yazidis, who live in the western part of the country, practice Yazidism. The world's largest Yazidi temple, Quba Mêrê Dîwanê, was completed in 2019 in the village of Aknalich.

There is a Jewish community in Armenia of approximately 750 people since independence with most emigrants leaving for Israel. There are currently two synagogues in Armenia – one in the capital, Yerevan, and the other in the city of Sevan located near Lake Sevan.
