We are not alone in our daily spiritual battle; the saints and angels always stand ready to come to our aid. Here is a great prayer to St. Michael, the Archangel:
O Michael, glorious prince, chief and champion of the heavenly host, guardian of the souls of men, conqueror of the rebel angels, minister in the house of God, our worthy captain under Jesus Christ, endowed with superhuman excellence and virtue: deign to free us all from every evil, who with full confidence have recourse to you; and by your powerful protection enable us to make progress every day in the faithful service of our God.
V/. Pray for us, most blessed Michael, prince of the Holy Church.
R/. That we may be made worthy of the promises of Christ.
Let us pray.
Almighty and eternal God, who in your own marvelous goodness and pity did, for the common salvation of man, choose the glorious Archangel Michael to be the prince of your Church; make us worthy, we pray, to be delivered by his beneficent protection from all our enemies, that at the hour of our death no one of them may approach to harm us, and that by the same Archangel Michael we may be brought into the presence of your high and heavenly Majesty. Through Christ our Lord. Amen.
