Our Holy Father Constantine of Synnada (7th c.)

His parents were Jews living at Synnada in Phrygia. One day when he was nine years old, he saw a Christian merchant make the sign of the Cross in the marketplace; and in imitation, without understanding its meaning, he began to make the sign. This became a habit with him, and he began to imitate other practices of the Christians around him, still without any understanding of the Christian faith. But by the power of the Cross, the grace of Christ began to grow in him secretly. He began to hear a voice within him revealing some of the mysteries of Christianity, and he began to be filled with a fervent love for the Savior.
