Feast of St. Michael the Archangel
Sancte Michael Archangele, defende nos in praelio, contra nequtitiam et insidias diaboli esto praesidum. Imperet illi Deus, supplices deprecamur: tuque, Princpes militiae coelestis, Satanam aliosque spiritus malignos, qui ad perditionem pervagantur in mundo, divina virtute, in infernum detrude. Amen - Prayer to St. Michael the Archangel in its traditional Latin formula and used by St. John Mary Vianney as a short form of exorcism
The English translation of the above prayer: "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 host, by the power of God, cast into hell Satan and all the wicked spirits, who roam through the world, seeking the ruin of souls. Amen."
Part of the Prayers ordered by Pope Leo XIII to be said kneeling after the Traditional Low Mass in Latin. Pope Pius XI asked that this prayer, after the "Salve Regina" ("Hail Holy Queen"), should be said for the conversion of Russia - could be one of the reasons why this was suppressed in Vatican II's "fabricated liturgy" (Card. Ratzinger, now Pope Benedict XVI), particularly after the celebration of the "New Mass"; see our post "When Mary Comes (III): Defence of Catholic Dogma & the Failed Papal 'Consecration of Russia'"
