Saint Patrick was from Roman Britain. When he was 16 he was captured and taken as a slave to Ireland. He eventually escaped and returned to his home. After he was ordained, he went back to Ireland and spent the rest of his life ministering there. He was the first bishop of Ireland.
Christ, be with me, Christ before me, Christ behind me, Christ in me, Christ beneath me, Christ above me, Christ on my right, Christ on my left, Christ where I lie, Christ where I sit, Christ where I arise, Christ in the heart of everyone who thinks of me, Christ in the mouth of everyone who speaks of me, Christ in every eye that sees me, Christ in every ear that hears me. (from The Breastplate of Saint Patrick)
Remember your mercies, O Lord. (Psalm 25)
