His ecclesiastical career advanced quickly: in 1963 he was elevated to senior archimandrite and on January 19, 1964, he was consecrated bishop by Catholicos Khoren.

From 1963, he became an aide to Catholicos Khoren I in which function he had many ecumenical contacts. He served as observer at the Second Vatican Council, the Lambeth Conference of 1968 and the Addis Ababa Conference of the heads of the Oriental Orthodox Churches. He lectured on theology, literature, history and culture at universities in Beirut, Romania, Moscow and Kotayyam (India).
