God is everywhere present; not a hair falls from the head or a sparrow fall to the ground without his knowledge. ... He has charged His angels with the ministry of watching and safeguarding every one of His creatures that behold not His face. Kingdoms have their angels assigned to them, and men have their angels; these latter it is to whom religion designates the Holy Guardian Angels. Our Lord says in the Gospel, "Beware lest ye scandalize any of these little ones, for their angels in heaven see the face of My Father." The existence of Guardian Angels, is, hence a dogma of the Christian faith: this being so, what ought not our respect be for that sure and holy intelligence that is ever present at our side; and how great our solicitude be, lest, by any act of ours, we offend those eyes which are ever bent upon us in all our ways!
