Prayer to the Guardian Angel

O Angel of Christ, my holy guardian and protector of my soul and body: forgive me all wherein I have sinned this day, and deliver me from all opposing evil of mine enemy, lest I anger my God by any sin. Pray for me, a sinful and unworthy servant, that thou mayest show me forth worthy of the kindness and mercy of the All-holy Trinity and of the Mother of my Lord Jesus Christ, and of all the saints. Amen.
