You may or may not know that Saint Patrick was not an Irishman. In fact, he was a Brit (a Romano-Briton to be precise) & as a teenager he was captured by the Irish & enslaved. After six some odd years of slavery the young Patrick heard a voice telling him to walk to a port 200 miles away where he would discover a ship that would lead him home. Indeed, Patrick obeyed the instruction, discovered the ship, eventually returned to his freedom, his homeland, & his eventual calling into the ministry of the church. Years later - as legend has it - Patrick experienced a vision of a man carrying a number of letters & inscribed on the letter handed to him were the words, "the voice of the Irish." And while Patrick read the letter he imagined he heard a chorus of voices crying out to him, "We appeal to you, holy servant boy, to come and walk among us." So Patrick went to the land of his former captors & the rest so to speak is history - with a good bit of Irish legend thrown in.
