Aremenians are dominately Christian. Their church is comparable to Coptic churches. They are considered Orthodox (or Oriental Orthodox). Propbably their church is like a Russian Orthodox church for the most part, just that they will speak their mother language within. They could also possibly be more of a Catholic style of church. Like the rest of Europe, Asia and the Middle East they could be basically from a number of denominations. I am just assuming it is most likely Orthodox though.
