In the Name of the Father, the Son and the Holy Spirit Amen.
Most glorious Prince of the Celestial army, Archangel St. Michael, defend us in the battle against the powers of darkness and their spiritual maliciousness.
Come to our aid, who were created by God and redeemed with the blood of Jesus Christ, His Son, and deliver us from the tyranny of the devil.
You are venerated by the Church as its Patron and Guardian and to you, the Lord has entrusted the souls who one day will occupy the heavenly mansions,
Pray, therefore, the God of Peace, to keep the devil crushed under our feet, so that he won't be able to enslave men unto himself and neither cause any harm to the Church.
Unite our prayers to Thine own and present them to Almighty God, so that His divine mercies may descend upon us.
Chain Satan and thrust him into the bottomless pit, whence he won't be able to seduce souls anymore.
Psalm. (To be recited standing and at the indication + should be made the sign of the cross).
May the Lord arise and His enemies be vanquished and may all those who hate Him, vanish from His presence.
As the smoke vanishes and as wax melts in fire, likewise should sinners perish from before His face.
V. ) Behold the Cross of the Lord, flee hostile powers.
R.) Has won the Lion of the tribe of Juda, the descendant of David.
V.) May Thy mercy O Lord, descend upon us.
R.) As we haved hoped in Thee.
We impose it upon you to flee, unclean spirit, satanic power, invasion of the infernal enemy, with all your legions, reunions and diabolic sects, in the name and with the authority of Our Lord Jesus + Christ. Be eradicated from the Church of God, driven from souls created in the image of God and redeemed by the precious blood of the Divine Lamb.
From now on do not dare, perfidious serpent, to beguile the human race, persecute the Church of God, to agitate and sift like wheat, God's elect.
Almighty God commands it to you, to Whom, in your great pride, presume to be similar. God the Father + the Son and Holy Spirit commands it to you.
Christ, the eternal Word of God made flesh + commands it to you, Who for the salvation of our progeny lost by your jealousy, "He let be humiliated and made Himself obedient unto death".
The powerful Mother of God, the Virgin Mary + commands it to you, Who from the first instant of her Immaculate Conception, because of her humility, has crushed your proud head.
The blood of the Martyrs and the powerful intercession of all the Saints commands it to you.
Therefore cursed dragon and every diabolical legion, we conjure you by the living + God, by the true + God, by the holy + God: cease too lay snares in the path of God's creatures and toast them the poison of eternal damnation: cease to harm the Church and to put obstacles to its freedom.
Go satan, author and master of deceits, enemy of man's salvation. Surrender the authority to Christ, surrender the authority to the Church which Christ acquired with His blood.
Humble yourself under the mighty hand of God, tremble and flee at the invocation which we make of the Holy and terrible name of that Jesus, which makes hell quake, to Whom the Celestial Virtues, Powers and Dominations are subject, Whom the Cherubim and Serafim praise incessantly saying: "Holy, Holy, Holy is the Lord, the God of the universe".
V.) O Lord hear our prayers.
R.) And let our cry come unto Thee.
O God of Heaven, God of Earth, God of the Angels, God of the Archangels, God of the Patriarchs, God of the Prophets, God of the Apostles, God of the Martyrs, God of the Confessors, God of the Virgins, God Who has the power to bestow life after death and rest after fatigue, since there is no other God beside Thee and neither can it be, eternal Creator of all things visible and invisible, we humbly beseech Thee to free us from every tyranny, snare, deceit and infestation of the infernal enemy and preserve us always from all harm. Through Jesus Christ, Our Lord, Amen.
