the school, 300 souls left the same year. (There is some doubt on when exactly these events took place. But all sources agree that they happened under the Catholicos Sabrisho). Some of the exiles went to the monastery of Mar Abraham on Mt. Izla, others were welcomed by Marcos, bishop of Balad, at his school. Still others went to the rival school-monastery of Beth Sahde in Nisibis itself. Only 20 persons stayed with Henana, and the school hardly struggled on. Legacy Two years after the death of Henana, the teachings of Theodore were canonized by an episcopal gathering, and the Christology of Theodore became the official doctrine of the Church. Of the many writings of Henana very little has been preserved, and the Church of the East has rejected him. But in order to refute him, Babai the Great clarified the Christology of the Church of the East, which otherwise might not have happened.
