Dedication of the Basilica of St Michael Archangel

Sancte Michael Archangele, defende nos in praelio. 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.

St. Michael, the archangel, defend us in battle. Be our protection against the malice and snares of the devil. We humbly beseech God to command him. And do thou, O prince of the heavenly host, by the divine power thrust into hell Satan and the other evil spirits who roam through the world seeking the ruin of souls. Amen.

Oremus.
Deus, qui, miro ordine, Angelórum ministeria hominúmque dispensas : concede propítius ; ut, a quibus tibi ministrántibus in cælo semper assistitur, ab his in terra vita nostra muniátur. Per Dóminum.

Let us pray.
O everlasting God, who hast ordained and constituted the services of Angels and men in a wonderful order : mercifully grant that as thy holy Angels alway do thee service in heaven, so by thy appointment they may succour and defend us on earth.
