Армянская апостольская церковь is one of the oldest Christian denominations in the world, tracing its origins back to the 1st century AD. It was founded by the apostles Тадей and Фаддей, who are believed to have spread Christianity in Armenia. The church is known for its unique traditions, liturgy, and the use of the Armenian language in its services. The church played a significant role in the history and culture of Armenia, especially after Armenia became the first nation to adopt Christianity as its state religion in 301 AD. Today, the Армянская апостольская церковь continues to be a vital part of Armenian identity, with a rich heritage of art, music, and theology.
