Saint Constantine was a native of the city of Synnada and of Jewish descent. From his youth he was drawn to the Christian Faith. Careful study of the teachings of Christ set his heart aflame, and he left his parents to become a monk. He was baptized with the name Constantine and received monastic tonsure.
When they brought him the Holy Cross, he kissed it with love and touched it to his head. The image of the Holy Cross impressed itself upon him throughout all his life. Having spent his God-pleasing life in strict asceticism, Saint Constantine departed peacefully to the Lord.
