In the name of the Father, and of the Son, and St-Spirit,
Thus it is.

Prayer With Saint Michel Archangel This prayer small exorcism that the laic ones can recite, great exorcism being reserved with the cases of diabolic possessions and being able to be practised only by the priest) made up to put the demon in escape, can preserve great evils the family and the company if, in particular, it is recited with enthusiasm, even by the simple ones.

Very glorious Prince of the celestial armies, holy Michel Archangel, defend us in the combat, against the principalities and the powers, the chiefs of this world of darkness, against the spirits of mischievousness spread in the airs (Ep 1).

Come to assistance of the men that God made with his image and his  resemblance, and repurchased at so high price of the tyranny of the demon (Sg 2,1 ; L Co).

It is you that holy Church venerates like its guard and his guard ; you to whom it Lord entrusted the repurchased hearts, to introduce them into the celestial happiness. Entreat God of peace that He crushes Satan under our feet, in order to remove any capacity to him to still retain the captive men, and to harm to The Church.

Present at the Almighty our prayers, so that, well quickly, on us the mercies go down from the Lord ; and seize yourself the antique snake, which isn’t other than the devil or Satan, to precipitate it connected in the abysses, in kind that it can allure never again nations (AP 20).

In the name of Jesus-Christ, our God and Lord, with intercession of Immaculate Virgin Mary, Mother of God, saint Michel Archangel, the saints Apostles Pierre and Paul and all the saints [ and pressed on the authority crowned of our ministry ], we undertake with confidence to push back the attacks and the tricks of the demon.

Psalm 67

(it upright is recited)

That God rises and that its enemies are dispersed; and what flees, in front of Him, those which hate it.

As smoke disappears, that they disappear; like wax melts in front of fire, thus perish the sinners in front of the face of God.
 

V: Here the Cross of the Lord, flee enemy powers.
R: It overcame, the Lion of the tribe of Juda, the kid of David.
V: That your mercy, Lord, are on us.
R: Just as we hoped in you.

We make you exorcism, malefic spirit, which that you would be, satanic power, invasion of the enemy infernal, legion, meeting or diabolic sect, with the name and by the virtue of Jesus-Christ , our Lord, would be torn off the Church of God and hearts created with the icon of God and repurchased by the invaluable blood of divine Lamb .

From now on you will not dare more, perfidious snake, to mislead mankind, to persecute the Church of God, nor to shake and sift, like wheat, the elected officials of God .

It orders you, God the Almighty  ; which, in your pride, you still claim to be similar, Him which wants that all the men are saved and arrive at the knowledge of the truth (1 Tm 2). It orders you, God the Father .

It orders you, God the Son .

It orders you, God the Holy Spirit .
It orders you, Christ, verb eternal of God makes flesh which, for hello of our race, lost by your jealousy, it is humiliated and returned obeying until dead (pH 2), which built its Church on the solid stone, and promised that the doors of the hell will never prevail against it, wanting to remain with it all over the days, until the consumption of the centuries (MT 28,20).

They order you the crowned sign of the Cross + and the virtue of all the mysteries of the Christian faith .

It orders you powerful Mother of God, the Virgin Mary, who, as of the first moment of her Immaculate Conception, by her humility, crushed your too proud head.

It orders you, the faith of the saints Apostle Pierre and Paul, and other Apostles .

They order you the blood of the martyrs and the pious intercession of all the saints and holy .

However thus, which cursed dragon and all the diabolic legion, we entreat you by alive God, true God, holy God, God who liked the world so much, that it gave him her Only son, so that whoever believes in Him does not perish, but have the eternal life (Jn 3); cease misleading the human creatures, and pouring the poison of the eternal damnation to them; cease harming to the Church, and putting obstacles at its freedom.

Goes on, Satan, inventor and Master of any fraud, enemy of the hello of the men. Yield the place to the Christ, in whom you not found anything of your works; yield the place to the Church, one, holy, catholic and apostolic, that Christ Himself acquired at the price of her blood.

Humiliate yourself under the powerful hand of God, trembles and flee, to invocation, made by us, of the saint and terrible Nom of Jesus, that the hells fear, to whom them virtues of the skies, the Powers and the Dominations are submitted, that “Chérubins” and the “Séraphins” unceasingly rent in their concerts, while saying: Saint, Saint, Saint is the Lord, God of the Armies.

V: Lord, satisfy my prayer.
R: And that my cry raises until you.
V: The lord is with you.
R: And with your spirit.

Speech

God of the sky and the ground, 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 have the power to give the life after death, rest after work ; because it have not other God that you, and it cannot have there if this isn’t you, the Creator of all the visible and invisible things, whose reign will not have end ; with humility we beg your glorious Majesty to condescend to deliver us strongly and to keep us healthy of any capacity, traps, lie and spite of the infernal spirits.

By Christ Our-Lord.
Thus it is.

Obstacles of the demon, deliver to us Lord. That you grant to your Church safety and freedom to be useful to you; we beg you, satisfy us.

That you condescend to humiliate the enemies of the Holy Church; we beg you, satisfy us.

( one sprinkles holy water the place where one is).

( Imprimatur, Paris, June 15, 1922. + Louis, Card. Dubois, Archbishop of Paris )
