He was an observer at Second Vatican Council before becoming metropolitan bishop of Mosul. At the time of his election as patriarch, Iwas had been archbishop of Baghdad and Basra.

As patriarch, he established a monastic seminary, met with Pope John Paul II during the Roman Pope's trip to Syria in 2001, and installed numerous metropolitans, including Baselios Thomas I as Catholicos of India. He celebrated his Silver Jubilee in 2005.
