From a sermon on the Feast of Our Guardian's Angels (October 2, 2021)
O holy Angel, who by God’s goodness has charge over me, who assists me in my necessities, who consoles me in my troubles, who obtains for me continually new favors, I thank you most sincerely. Gentle Guardian, continue your charitable care; defend me against my enemies, put away from me all occasions of sin, make me obedient to your inspirations and faithful to follow them.
In the presence of Jesus Christ and the whole court of Heaven, I choose you for my protector, my defender, my guide and my advocate. I beg you to govern my whole life: my memory, understanding, will, inclinations, and desires. O holy Angel, I love you, and wish to love you always. A thousand times I praise the Lord for the heavenly gifts with which He has adorned you, for the graces with which He has sanctified you, and for the glory with which He has crowned you. Guard and guide me now and at the hour of my death. Never leave me unprotected until you have brought me safe to Heaven. Amen.
