PRAYER TO SAINT MICHAEL:
LONGER VERSION PRAYER AGAINST SATAN and THE REBELLIOUS ANGELS PUBLISHED BY ORDER OF H. H. POPE LEO XIII

The Holy Father exhorts priests 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. The faithful also may say it in their own name, for the same purpose, as any approved prayer. Its use is recommended whenever action of the devil is suspected, causing malice in men, violent temptations and even storms and various calamities.

It could be used as a solemn exorcism (an official and public ceremony, in Latin), to expel the devil: It would then be said by a priest, in the name of the Church and only with the Bishop's permission.

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

PRAYER TO SAINT MICHAEL THE ARCHANGEL

Most glorious Prince of the Heavenly Armies, Saint Michael the Archangel. defend us in "our battle against principalities and powers, against the rulers of this world of darkness, against the spirits of wickedness in the high places" (Ephes. 6:12). Come to the assistance of men whom God has created to His likeness and whom He has redeemed at a great price from the tyranny of the devil. Holy Church venerates thee as her guardian and protector; to thee, the Lord has entrusted the souls of the redeemed to be led into heaven. Pray therefore the God of Peace to crush Satan beneath our feet, that he may no longer retain men captive and do injury to the Church. Offer our prayers unto the Most High, that without delay they may draw His mercy down upon us; take hold of "the dragon, the old serpent, which is the devil and Satan." Bind him and cast him into the bottomless pit "so that he may no longer seduce the nations" (Apoc. 20:2).
