Armenian Apostolic are not in communion with Rome. However of all the Orthodox, (in my experience) the Armenian Apostolic are the least hostile tward Rome. One Armenian priest told me, that in Armenia, Orthodox and Catholics were fighting the same enemy, Communism, and in Lebanon, Iraq and Iran, they were fighting against Islam all the enemies were attacking Chrisitanity, so most Armenians forgot who you were in communion with, and focused on attending Mass, and having a priest administer the Sacraments, Catholic or Apostolic.

Now based on Canon Law, this was wrong, but based on the spiritual needs of the time and place it was a manifestation of God’s love for us all, Orthodox and Catholic.
