According to Eusebius: The story of the healing and Thaddeus' evangelizing efforts resulted in the growing of Christian communities in southern Armenia, northern Mesopotamia and in Syria east of Antioch. Thaddeus' story is embodied in the Syriac document, Doctrine of Addai, which recounts the role of Addai and makes him one of the 72 Apostles sent out to spread the Christian faith. By the time the legend had returned to Syria, the purported site of the miraculous image, it had been embroidered into a tissue of miraculous happenings. The story was retold in elaborated form by Ephrem the Syrian. Various traditions St. Addai also appears in the First Apocalypse of James and the Second Apocalypse of James.
