Religion in Ukraine
Adherents of Oriental Orthodox Christianity in Ukraine are mainly ethnic Armenians. Historical ties between peoples of Ukraine and Armenia have resulted in significant presence of Armenian diaspora in Ukraine throughout history and up to the modern times. Most of ethnic Armenians in Ukraine are adherents of the Armenian Apostolic Church, one of main churches of the Oriental Orthodoxy, distinctive from Eastern Orthodoxy in terms of particular miaphysite christology. In spite of those theological differences, relations between Armenian Apostolic Church and various Eastern Orthodox Churches in Ukraine are friendly. There is an Armenian eparchy (diocese) in Ukraine, centered in Armenian Cathedral of Lviv, and also there are many Armenian churches and other monuments on the territory of Ukraine.
