Adherents of Oriental Orthodox Christianity in Azerbaijan are mainly ethnic Armenians . The Armenian Apostolic Church currently has no community outside the Nagorno-Karabakh Republic . Before the outbreak of the war , Armenians formed the largest Christian population in the country . Today , Armenian churches in Azerbaijan remain closed , because of the large outmigration of Armenians and fear of Azerbaijani attacks . During the Nagorno-Karabakh War , despite the constitutional guarantees against religious discrimination , numerous acts of vandalism against the Armenian Apostolic Church have been reported throughout Azerbaijan . At the height of the Baku pogrom in 1990 , the Armenian Church of St. Gregory Illuminator in was set on fire , but was restored in 2004 and is not used anymore
