St. Paul, a Jewish citizen of Rome, was named Saul at birth. The New Testament describes Saul as an opponent of Jesus and his teachings, actively persecuting and arresting Christians.
One day, while travelling from Jerusalem to Damascus, Saul was struck blind by a bright ray of light, and heard the voice of God speaking to him. His fellow travelers led him into Damascus, where a follower of Jesus restored his sight. Saul then became a devout Christian, changed his name to Paul, and preached widely throughout Greece and the eastern Roman Empire before being arrested and executed.
