"Bless the Lord, all ye His hosts:
you ministers of His who do His will."
Alleluia Verse: Mass of the Guardian Angels
"It is of faith, on the testimony of the Scriptures and of unanimous tradition, that God commits to his Angels the guardianship of men, who are called to contemplate him together with these blessed spirits in their common fatherland. Catholic theology teaches that this protection is extended to every member of the human race, without any distinction of just and sinners, infidels and baptized. To ward off dangers; to uphold man in his struggle against the demons; to awaken in him holy thoughts; to prevent him from sinning, and even, at times, to chastise him; to pray for him, and present his prayers to God; such is the office of the Guardian Angel. So special is his mission that one Angel does not undertake the guardianship of several persons simultaneously; so diligent is his care that he follows his ward from the first day to the last of his mortal existence, receiving the soul as it quits this life, and bearing it from the feet of the sovereign Judge to the place it has merited in heaven, or to its temporary sojourn in the place of expiation and purification.
