From Goffine's Devout Instructions:
MICHAEL is the prince of the heavenly armies, who first contended against the proud Lucifer. The holy Church honors him as a particular defender, and the faithful call upon him in all dangers of soul and body, but they particularly implore his intercession at the hour of death, in order that, after having, according to his example, courageously fought against Satan, they may receive the crown of victory, and that their souls may by him be brought before the throne of God. Let us also venerate him, and, full of confidence, cry out with the holy Church, "Holy archangel Michael, protect us in battle, that we may not perish in the tremendous judgment."
O God, Who with wonderful order dost direct the miuistry of angels and of men, mercifully grant that our life on earth may be protected by those who ever minister before Thee in heaven. Through Christ Jesus our Lord, Amen.
Epistle: Apocalypse 1:1-5
In those days God made known the things which must shortly come to pass, and signified, sending by His angel to His servant John, who hath given testimony to the word of God, and the testimony of Jesus Christ, what things soever He hath seen. Blessed is he that readeth and heareth the words of this prophecy, and keepeth those things which are written in it. For the time is at hand. John to the seven churches which are in Asia: Grace be unto you and peace from Him that is, and that was, and that is to come, and from the seven spirits which are before His throne, and from Jesus Christ, Who is the faithful witness, the first-begotten of the dead, and the prince of the kings of the earth, Who hath loved us, and washed us from our sins, in His own blood.
This epistle is read to-day because Saint Michael so bravely contended against the sedition of Satan, and, after gaining the victory, drove him and his adherents from heaven.
Gospel: Matthew 18:1-10
 At that time the disciples came to Jesus, saying: Who thinkest Thou is the greater in the kingdom of heaven? And Jesus calling unto Him a little child, set him in the midst of them, and said: Amen I say to you, unless you be converted, and become as little children, you shall not enter into the kingdom of heaven. Whosoever therefore shall humble himself as this little child, he is the greater in the kingdom of heaven. And he that shall receive one such little child in My name receiveth Me. But he that shall scandalize one of these little ones that believe in Me, it were better for him that a millstone should be hanged about his neck, and that he should be drowned in the depth of the sea. Woe to the world because of scandals. For it must needs be that scandals come, but nevertheless, woe to that man by whom the scandal cometh. And if thy hand or thy foot scandalize thee, cut it off, and cast it from thee. It is better for thee to go into life maimed or lame, than having two hands or two feet, to be cast into everlasting fire. And if thy eye scandalize thee, pluck it out, and cast it from thee. It is better for thee having one eye to enter into life, than having two eyes to be cast into hell fire. 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.
Prayer to Saint Michael the Archangel
Great prince of heaven, Saint Michael, to thy protection commend my soul and body, and, by the glory which thou possessest in heaven, I beseech thee that thou wouldst ever assist me, particularly at the close of my life; that thou wouldst strengthen my faint-heartedness, and obtain for me from God the remission of my sins, and au entire submission to His holy will, that my soul may depart full of comfort. Then receive it, and bring it, under the guidance of the holy angels, before the face of God, to enjoy the contemplation of Him for all eternity. Amen.
