St. Michael the Archangel, defend us in battle. Be our defense against the wickedness and snares of the Devil. May God rebuke him, we humbly pray, and do thou, O Prince of the Heavenly Host, by the power of God, cast into hell Satan and all the evil spirits who prowl about the world seeking the ruin of souls. Amen.
— Prayer to St. Michael the Archangel
In the Gospel for the First Sunday of Lent, St. Mark tells us that when Jesus was tempted by Satan in the desert, "the angels ministered to him." We don't know for sure which angels came to his aid, but the odds are good that St. Michael was involved, or at least that he sent them.
