Patrick heard voices calling him to show Ireland a better way of life. He was then captured and enslaved in Ireland for seven years, where he prayed daily. One night he escaped on a boat and returned home, promising to become a bishop if spared. Years later, the voices called him back to Ireland, where he converted the people to Christianity by driving out snakes and pagan gods and using a shamrock to represent the Holy Trinity. We now celebrate Saint Patrick's Day in remembrance of his missionary work in Ireland.
