Angel of God, my Guardian dear,
to whom His love commits me here,
ever this day be at my side,
to light and guard, to rule and guide, Amen.
qui custos es mei,
me, tibi commíssum pietáte supérna,
rege et gubérna.
That every individual soul has a guardian angel has never been defined by the Church, and is, consequently, not an article of faith; but it is the "mind of the Church", as St. Jerome expressed it: "how great the dignity of the soul, since each one has from his birth an angel commissioned to guard it."
In the Bible this doctrine is clearly discernible and its development is well marked. In Genesis 28-29, angels not only act as the executors of God's wrath against the cities of the plain, but they deliver Lot from danger; in Exodus 12-13, an angel is the appointed leader of the host of Israel, and in 32:34, God says to Moses: "my angel shall go before thee." At a much later period we have the story of Tobias, which might serve for a commentary on the words of Psalm 90:11: "For he hath given his angels charge over thee; to keep thee in all thy ways." (Cf. Psalm 33:8 and 34:5.) Lastly, in Daniel 10 angels are entrusted with the care of particular districts; one is called "prince of the kingdom of the Persians", and Michael is termed "one of the chief princes"; cf. Deuteronomy 32:8; and Ecclesiasticus 17:17.
This sums up the Old Testament doctrine on the point; it is clear that the Old Testament conceived of God's angels as His ministers who carried out his behests, and who were at times given special commissions, regarding men and mundane affairs. There is no special teaching; the doctrine is rather taken for granted than expressly laid down; cf. 2 Machabees 3:25; 10:29; 11:6; 15:23.
But in the New Testament the doctrine is stated with greater precision. Angels are everywhere the intermediaries between God and man; and Christ set a seal upon the Old Testament teaching: "See that you despise not one of these little ones: for I say to you, that their angels in heaven always see the face of my Father who is in heaven." (Matthew 18:10). A twofold aspect of the doctrine is here put before us: even little children have guardian angels, and these same angels lose not the vision of God by the fact that they have a mission to fulfil on earth.
Without dwelling on the various passages in the New Testament where the doctrine of guardian angels is suggested, it may suffice to mention the angel who succoured Christ in the garden, and the angel who delivered St. Peter from prison. Hebrews 1:14 puts the doctrine in its clearest light: "Are they not all ministering spirits, sent to minister for them, who shall receive the inheritance of salvation?" This is the function of the guardian angels; they are to lead us, if we wish it, to the Kingdom of Heaven.

God our Father,
in your loving providence
you send your holy angels to watch over us.
Hear our prayers,
defend us always by their protection
and let us share your life with them for ever.
We ask this through our Lord Jesus Christ, your Son,
who lives and reigns with you and the Holy Spirit,
one God, for ever and ever. Amen.
First Reading: Exodus 23: 20-23
"Behold, I send an angel before you, to guard you on the way and to bring you to the place which I have prepared. Give heed to him and hearken to his voice, do not rebel against him, for he will not pardon your transgression; for my name is in him.
"But if you hearken attentively to his voice and do all that I say, then I will be an enemy to your enemies and an adversary to your adversaries.
"When my angel goes before you, and brings you in to the Amorites, and the Hittites, and the Perizzites, and the Canaanites, the Hivites, and the Jebusites, and I blot them out.
Second Reading(places where it is a Solemnity): Revelation 12:7-12
Now war arose in heaven, Michael and his angels fighting against the dragon; and the dragon and his angels fought, but they were defeated and there was no longer any place for them in heaven. And the great dragon was thrown down, that ancient serpent, who is called the Devil and Satan, the deceiver of the whole world--he was thrown down to the earth, and his angels were thrown down with him. And I heard a loud voice in heaven, saying, "Now the salvation and the power and the kingdom of our God and the authority of his Christ have come, for the accuser of our brethren has been thrown down, who accuses them day and night before our God. And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death. Rejoice then, O heaven and you that dwell therein! But woe to you, O earth and sea, for the devil has come down to you in great wrath, because he knows that his time is short!"
Gospel Reading: Matthew 18:1-5, 10
At that time the disciples came to Jesus, saying, "Who is the greatest in the kingdom of heaven?" And calling to him a child, he put him in the midst of them, and said, "Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven. Whoever humbles himself like this child, he is the greatest in the kingdom of heaven.
"Whoever receives one such child in my name receives me.
"See that you do not despise one of these little ones; for I tell you that in heaven their angels always behold the face of my Father who is in heaven.

I’m certainly of mind that the angels of the Lord exist. How often and why they intervene in our affairs is one of God’s mysteries.
