Saint 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, oh prince of the heavenly spirit, by the power of God, cast into hell satan and all the evil spirits who roam the world seeking the ruin of souls.
Amen
This is part of the Leonine prayers introduced by Pope Leo in the early 1900s to counter the spread of communism in Russia. Perfect timing.
Didn't work too well, did it? Communism spread and millions died - still going strong.
The leonine prayers were removed from the mass in the sixties, after Vatican II. So removed by the commies. Most Holy Family monastery has some good info.
Well, all I can say is it was an EPIC FAIL - by their fruits ye shall know them.
