He was born in Constantinople at the time that his father was an envoy from the King of Armenia to the Byzantine court. He was the tenth Archbishop of Armenia, and as such governed the Church for fifty years. His episcopate was distinguished, among other things, by the translation of the Scriptures into Armenian. He was told in a vision that Armenia would, one day, fall away from the pure, Orthodox faith. This great hierarch entered peacefully into rest in 440, and went to the Lord.
