Casting Instructions for ‘Exorcism Prayer’
By a Priest Only Prayer to St. Michael the Archangel In the Name of the Father, and of the Son, and of the Holy Ghost. Amen. Most glorious Prince of the Heavenly Armies, Saint Michael the Archangel, defend us in our battle against principalities and powers, against the rulers of the world of darkness, against the spirits of wickedness in the high places Eph., 6:12. Come to the aid of men whom God has created to His likeness and whom He has redeemed at a great price from the tyranny of the devil. The Holy Church venerates you as her guardian and protector; to you, 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, he may no longer retain men captive and do injury to the Church. Offer our prayers to 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 that he may no longer seduce the nations. Rev. 20:2-3
Exorcism
In the Name of Jesus Christ, our God and Lord, strengthened by the intercession of the Immaculate Virgin Mary, Mother of God, of Blessed Michael the Archangel, of the Blessed Apostles Peter and Paul and all the Saints. and powerful in the holy authority of our ministry, we confidently undertake to repulse the attacks and deceits of the devil.
God arises; His enemies are scattered and those who hate Him flee before Him. As smoke is driven away, so are they driven; as wax melts before the fire, so the wicked perish at the presence of God.
V. Behold the Cross of the Lord, flee bands of enemies. R. The Lion of the tribe of Juda, the offspring of David, hath conquered. V. May Thy mercy, Lord, descend upon us. R. As great as our hope in Thee.
Thus, cursed dragon, and you, diabolical legions, we adjure you by the living God, by the true God, by the holy God, from the God who so loved the world that He gave up his only Son, that every soul believing in Him might not perish but have life everlasting; St.Jn. 3:16 stop deceiving human creatures and pouring out to them the poison of eternal damnation; stop harming the Church and hindering her liberty. Begone, Satan, inventor and master of all deceit, enemy of mans salvation. Give place to Christ in Whom you have found none of your works; give place to the One, Holy, Catholic and Apostolic Church acquired by Christ at the price of His Blood. Stop beneath the all-powerful Hand of God; tremble and flee when we invoke the Holy and terrible Name of Jesus, this Name which causes hell to tremble, this Name to which the Virtues, Powers and Dominations of heaven are humbly submissive, this Name which the Cherubim and Seraphim praise unceasingly repeating: Holy, Holy, Holy is the Lord, the God of Hosts.
V. O Lord, hear my prayer. R. And let my cry come unto Thee. V. May the Lord be with thee. R. And with thy spirit. Let us pray.
God of heaven, God of earth, God of Angels, God of Archangels, God of Patriarchs, God of Prophets, God of Apostles, God of Martyrs, God of Confessors, God of Virgins, God who has power to give life after death and rest after work: since there isn’t any other God than Thee and there can be no other, for Thou art the Creator of all things, visible and invisible, of Whose reign there shall be no end, we humbly prostrate ourselves before Thy glorious Majesty and we beseech Thee to deliver us by Thy power from all of the tyranny of the infernal spirits, from their snares, their lies and their furious wickedness.
Deign, O Lord, to grant us Thy powerful protection and to keep us safe and sound.
We beseech Thee through Jesus Christ Our Lord.
Amen.
V. In the snares of the devil, R. Deliver us, O Lord. V. That Thy Church may serve Thee in peace and liberty: R. We beseech Thee to hear us. V. That Thou may crush down all enemies of Thy Church: R. We beseech Thee to hear us. (Holy water is sprinkled in the place where we may be.)
