Saint Michael the Archangel, defend us in the day of Battle; Be our safeguard 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 other evil spirits, who prowl throughout the world, seeking the ruin of souls. Amen.

(This powerful prayer of exorcism was composed by Pope Leo XIII; in a vision, he had been shown the fearful battle to be waged between satan and Saint Michael, over the Church of the future.  Now, as never before, the Church needs the intercession of Saint Michael!  Please pray this prayer every day.)

Indulgenced by Pope Leo XIII, September 25, 1888.  Racolta #447, 2004
