Prayer To Your Guardian Angel
Angel of God, my guardian dear, to whom God's love commits me here, ever this day be at my side, to light and guard, rule and guide. Amen.
From infancy to death human life is surrounded by their (the angels) watchful care and intercession. Beside each believer stands an angel as protector and shepherd leading him to life. Already here on earth the Christian life shares by faith in the blessed company of angels and men united to God.
