The disciples approached Jesus and said, “Who is the greatest in the Kingdom of heaven?” He called a child over, placed it in their midst, and said, “Amen, I say to you, unless you turn and become like children, you will not enter the Kingdom of heaven. Whoever humbles himself like this child is the greatest in the Kingdom of heaven. And whoever receives one child such as this in my name receives me.
“See that you do not despise one of these little ones, for I say to you that their angels in heaven always look upon the face of my heavenly Father.”
In today's Gospel, Jesus is not speaking of just any Angels, but rather of Angels that are greater than others. But when He says, "The face of my Father," He means nothing else than their fuller confidence, and their great honor. High dignity of souls, that each from its birth has an Angel set in charge over it!
The Angels offer to God daily the prayers of those that are to be saved by Christ; it is therefore perilous to despise him whose desires and requests are conveyed to the eternal and invisible God, by the service and ministry of Angels.
They are called our Angels who are indeed the Angels of God; they are God's because they have not forsaken Him; they are ours because they have begun to have us for their fellow-citizens. As they now behold God, so shall we also behold Him face to face, of which vision John speaks, "We shall see him as he is"(1 John 3:2).

Dear Guardian Angel,
in his goodness God gave you to me to guide, protect, and enlighten me, and to bring me back to the right way when I go astray. Encourage me when I am disheartened, and instruct me when I err in my judgement. Help me to become more Christ-like, and so some day to be accepted into the company of Angels and Saints in heaven. Amen.
