A simple exorcism

Holy Father Pope Leo XIII exhorted (May 18, 1890) all to say this prayer as often as possible as a simple exorcism to curb the power of the devil, and prevent him from doing harm. Its use is recommended whenever action of the devil is suspected, causing malice in men, violent temptations,and even storms and various calamities.

In the name of the Father and of the Son and of the Holy Ghost, Amen.

Let God arise and let his enemies be scattered and let them that hate him flee before his face. As smoke vanish so let them vanish away as wax melteth before the fire, so let the wicked perish at the presence of God. Judge Thou, O Lord, them that wrong me: overthrow them that fight against me. Let them be confounded and ashamed that seek after my soul. Let them be turned back and be confounded that devise evil against me. Let them become as dust before the wind and let the angel of the Lord straiten them. Let their way become dark and slippery and let the angel of the Lord pursue them. For without cause they have hidden their net for me unto destruction: without cause they have upbraided my soul. Let the snare which he knoweth not come upon him, and let the net which he hath hidden catch him: and into that very snare let him fall. But my soul shall rejoice in the Lord and shall be delighted in his salvation.

Glory be to the Father and to the Son and to the Holy Ghost, as it was in the beginning is now and ever shall be, world without end. Amen.
