Maestro Marek Raczyński's Sancte Michael Archangele is an... interesting work, to be sure; his website, in English. The motet sets the Latin of the well-known prayer Saint Michael the Archangel, defend us in battle, which was suppressed by Paulus VI (as the tsunami of wickedness unleashed in the years following the Council was gathering strength, ahem) and is returning, gradually, in an increasing number of parishes. The horrid liturgists claim to worry that it amounts to an 'invidious addition' to the proper Pauline Ordo Missae; those less enamored of the post-conciliar innovations know better.
Sancte Michael Archangele, defende nos in proelio, contra nequitiam et insidias diaboli esto praesidium. Imperet illi Deus, supplices deprecamur: tuque, Princeps militiae caelestis, Satanam aliosque spiritus malignos, qui ad perditionem animarum pervagantur in mundo, divina virtute, in infernum detrude. Amen.
Saint Michael the Archangel, defend us in battle; be our defense 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 thrust into hell Satan and all the evil spirits who prowl about the world for the ruin of souls. Amen.
