Take note, you heathen, it’s the Feast of St. Michael the Archangel today. So here’s a prayer:
Holy Michael, 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 evil spirits
who wander through the world for the ruin of souls.
