Saint Michael the Archangel, defend us in battle. Be our protection against the wickedness and snares of the devil. May God rebuke him, we humbly pray; and do Thou, O Prince of Heavenly Host – by the Power of God – cast into hell, satan and all evil spirits, who prowl about the world seeking the ruin of souls. Amen.

THERE was war in heaven: Michael and his angels fought against the dragon;
and the dragon fought and his angels, and prevailed not;
neither was their place found any more in heaven.
(Rev. xii. 7)
