Saint 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 other evil spirits who prowl about the world
seeking the ruin of souls. Amen.
Pope Leo XIII
(St. Michael, the Archangel’s Feast Day: September 29)
