A prayer that is known and loved by those of us old enough to remember the prayers said in convent schools. One that I still use (60 years later) every day with the comfort and strength of old familiarity.
O Holy Michael, Archangel,
Defend us in the day of battle
Be our safeguard against the wickedness and snares of the Devil.
May God restrain him, we humbly pray, and do Thou,
O Prince of the Heavenly Host, by the power of God
Thrust down into Hell, Satan and all the other wicked spirits,
Who wander through the world to the ruin of souls.
