Act of Consecration to Our Guardian Angel

Angel of God, prince of Heaven, watchful guardian, faithful guide, charitable pastor, I rejoice that God has created thee with so many perfections; that he has sanctified thee by his grace, and crowned thee with glory, after having persevered in his service. May God be praised forever for all he has done for thee. Be thou blessed for all the good thou hast procured me and my companions.
I abandon to thee my body, soul, memory, understanding, will, inclination, and senses. Govern all, dispose of all, purify, enlighten, perfect all. Beg our Lord to shed upon me and my companions his abundant benedictions; that persevering until death in his grace, we may deserve to possess him eternally with thee in glory. Amen.
