The Georgian Apostolic Church is one of the oldest Christian churches in the world, tracing its roots back to the early 4th century. It was officially established as the state church of Georgia when King Mirian III converted to Christianity, largely influenced by Saint Nino, who is credited with spreading Christianity in the region. The church follows the Eastern Orthodox tradition and is part of the Oriental Orthodox communion. It has its own unique liturgical practices and a rich cultural heritage, including ancient manuscripts and religious art. The Holy Synod governs the church, and its spiritual leader is the Catholicos-Patriarch of All Georgia.
