Prayer to St. Michael
St. 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 the heavenly hosts,
By the power of God,
Thrust into hell Satan and all evil spirits
Who prowl about the world seeking the ruin of souls.
Pope Leo XIII (1884)
