Pope Leo XIII Prayer to St. Michael

The well-known short version of this prayer follows in English and Latin. The Pope ordered this prayer to be recited daily after Low Mass in all the churches throughout the Catholic world. However this practice was almost completely swept away in the 1960s by liturgical changes made in the wake of Vatican Council II.

Saint Michael the Archangel, defend us in battle, be our protection against the malice 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 evil spirits who wander through the world for the ruin of souls. Amen.

In Latinam:

Sáncte Míchael Archángele, defénde nos in proélio, cóntra nequítiam et insídias diáboli ésto præsídium. Ímperet ílli Déus, súpplices deprecámur: tuque, prínceps milítiæ cæléstis, Sátanam aliósque spíritus malígnos, qui ad perditiónem animárum pervagántur in múndo, divína virtúte, in inférnum detrúde. Ámen

V. Behold the Cross of the Lord; be scattered ye hostile powers.

R. The Lion of the tribe of Judah has conquered, the root of David.

V. Let Thy mercies be upon us, O Lord.

R. As we have hoped in Thee.

V. O Lord, hear my prayer.

R. And let my cry come unto Thee.

Let us pray.

O God, the Father of our Lord Jesus Christ, we call upon Thy holy Name, and as supplicants, we implore Thy clemency, that by the intercession of Mary, ever Virgin Immaculate and our Mother, and of the glorious St. Michael the Archangel, Thou wouldst deign to help us against Satan and all the other unclean spirits who wander about the world for the injury of the human race and the ruin of souls. Amen.
