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. 
God bless,
