Before entering the ecclesiastical career he was a shepherd of flocks and had a wife. Not many details are known about his life. At the Council of Nicaea (325) he distinguished himself for his combative spirit against Arianism. In the Greek Church, which honors him with the title of “thaumaturge,” he enjoys a very popular cult. His liturgical feast is celebrated on 12 Dec. On that occasion at Piraeus, whose cathedral is precisely dedicated to St S., three days of festivities were held. Even at Athens, in the quarter of the stadium, popular religious manifestations take place. His body is venerated today at Corfu.
