The Armenian Apostolic Church is the world’s oldest national church. It is part of Oriental Orthodoxy and is one of the most ancient Christian communities. Armenia was the first country to adopt Christianity as its official religion in the early fourth century (traditionally in 301).
Despite the potentially confusing nomenclature (the word “Oriental” being synonymous with “Eastern”), Oriental Orthodox churches are distinct from those that are collectively referred to as the Eastern Orthodox Church. The Oriental Orthodox communion comprises six churches: Coptic, Ethiopian, Eritrean, Syriac, Malankara Syrian (Indian Orthodox Church) and Armenian Apostolic churches.
