Born in a village of Little Russia (now Belarus), he was kidnapped as a boy and sold to a Turkish tanner as a slave. He spent the next twenty-seven years in Usaki in Asia Minor, where he was forced to embrace Islam. After long years of servitude he escaped and, reclaiming his Christianity, went to the Holy Mountain, became a monk and lived for twelve years. Tormented by his former apostasy, he determined to suffer martyrdom for Christ. With the permission of his elder, Joseph, he returned to Usaki and showed himself to his former owner wearing his monastic habit. He was tortured, thrown into prison, and finally beheaded on on Ascension Day of 1730. His relics are buried on the island of Patmos in the Church of St John the Theologian, where they work many miracles.
