A disciple of St Niphon, Patriarch of Constantinople, he lived in asceticism on the Holy Mountain. He had such great love for Christ the Lord that all his asceticism seemed to him inadequate, and he longed to suffer for love of his Lord. He therefore went to Constantinople, where he openly confessed the Holy Trinity and the Son of God before the Turks. The furious Turks beheaded him on October 26th, 1536.
