Perhaps no aspect of Catholic piety is as comforting to parents as the belief that an angel protects their little ones from dangers real and imagined. Yet guardian angels are not just for children. Their role is to represent individuals before God, to watch over them always, to aid their prayer and to present their souls to God at death (Rev.8). The concept of an angel assigned to guide and nurture each human being is a development of Catholic doctrine and piety based on Scripture but not directly drawn from it. Jesus' words in Matthew 18:10 best support the belief: "See that you do not despise one of these little ones, for I say to you that their angels in heaven always look upon the face of my heavenly Father."
Prayer to My Guardian Angel
Angel of God's light, whom God sends as a companion for me on earth, protect me from the snares of the devil, and help me to walk always as a child of God, my Creator.Angel of God's truth, whose perfect knowledge serves what is true, protect me from deceits and temptations. Help me to know the truth, and always to live the truth. Angel of God's love, who praises Jesus Christ, the only Son of God, who sacrificed His life for love of us, sustain me as I learn the ways of Divine love, of sacrificial generosity, of meekness and lowliness of heart. Thank You, my heavenly friend, for your watchfull care. At the moment of my death, bring me to heaven, where the one true God, Who is light, Truth and Love, lives and reigns forever and ever. Amen.
