Venerable Isaac, Dalmatius and Faustus, Ascetics of the Dalmatian Monastery in Constantinople

Isaac was a Syrian hermit who came to Constantinople and, according to the historians of the time, confronted Emperor Valens in 378 over his support for the Arian party, foretelling that he would not return from his campaign; Valens fell at Adrianople. Isaac founded one of the first monasteries of the city. Dalmatius, an officer of Theodosius the Great, left the army and his family and became a monk under Isaac with his son Faustus, succeeding him as abbot; the house became known as the Dalmatian monastery. In 431 Dalmatius led the monks of the capital in procession to the emperor in support of the Council of Ephesus. Faustus followed his father's way of life.
