A beautiful prayer (a minor exorcism) that anyone can pray to ask Our Lord to drive the lingering influence of Satan away from a
place. Recommended by His Eminence Raymond Leo Cardinal Burke for use by the laity, August 2, 2014.
EXORCISM OF SATAN AND THE FALLEN ANGELS
In the name of the Father, and of the Son, and of the Holy
Spirit. Amen.
 
Prayer to Saint Michael the Archangel
ST. MICHAEL the Archangel, illustrious leader of the
heavenly army, defend us in the battle against principalities
and powers, against the rulers of the world of darkness and the
spirit of wickedness in high places. Come to the rescue of
mankind, whom God has made in His own image and
likeness, and purchased from Satan’s tyranny at so great a
price. Holy Church venerates you as her patron and guardian.
The Lord has entrusted to you the task of leading souls of the
redeemed to heavenly blessedness. Entreat the Lord of peace
to cast Satan down under our feet, so as to keep him from
further holding man captive and doing harm to the Church.
Carry our prayers up to God’s throne, that the mercy of the
Lord may quickly come and lay hold of the beast, the serpent
of old, Satan and his demons, casting him in chains into the
abyss, so that he can no longer seduce the nations.
 
Exorcism
IN THE name of Jesus Christ, Our Lord and God, by the
intercession of Mary, spotless Virgin and Mother of God, of
St. Michael the Archangel, of the blessed Apostles Peter and
Paul, and of all the saints, and by the authority residing in our
holy ministry, we steadfastly proceed to combat the onslaught
of the wily enemy.
 
Psalm 67
P:   God arises; His enemies are scattered, and those who hate
Him flee before Him.
All: As smoke is driven away, so are they driven; as wax
melts before the fire, so the wicked perish before God.
P.   See the Cross of the Lord; begone, you hostile powers!
All. The stem of David, the Lion of Judah’s tribe hath
conquered.
P.   May Your mercy, Lord, remain with us always.
All. For we put our whole trust in You.
 
WE CAST you out, every unclean spirit, every satanic power,
every onslaught of the infernal adversary, every legion, every
diabolical group and sect, in the name and by the power of
Our Lord Jesus  Christ. We command you, begone and fly
far from the Church of God, from the souls made by God in
His image and redeemed by the Precious Blood of the Divine
Lamb.  No longer dare, cunning serpent, to deceive the
human race, to persecute God’s Church, to strike God’s elect
and to sift them as wheat.  For the Most High God
commands you,  He to Whom you once proudly presumed
yourself equal; He Who wills all men to be saved and come to
the knowledge of truth. God the Father  commands you. God
the Son  commands you. God the Holy  Spirit commands
you. Christ, the eternal Word of God made flesh, commands 
you, Who humbled Himself, becoming obedient even unto
death, to save our race from the perdition wrought by your
envy; Who founded His Church upon a firm rock, declaring
that the gates of Hell should never prevail against her, and that
He would remain with her all days, even to the end of the
world. The sacred mystery of the Cross  commands you,
along with the power of all mysteries of Christian faith.  The
exalted Virgin Mary, Mother of God,  commands you, who
in her lowliness crushed your proud head from the first
moment of her Immaculate Conception. The faith of the holy
Apostles Peter and Paul and the other Apostles  commands
you. The blood of martyrs and the devout prayers of all holy
men and women command  you.

Therefore, accursed dragon and every diabolical legion, we
adjure you by the living  God, by the true  God, by the holy
 God, by God, Who so loved the world that He gave His
only-begotten Son, that whoever believes in Him might not
perish but have everlasting life; to cease deluding human
creatures and filling them with the poison of everlasting
damnation; to desist from harming the Church and hampering
her freedom. Begone, Satan, father and master of lies, enemy
of man’s welfare. Give place to Christ, in Whom you found
none of your works. Give way to the one, holy, catholic, and
apostolic Church, which Christ Himself purchased with His
Blood. Bow down before God’s mighty hand, tremble and flee
as we call on the holy and awesome name of Jesus, before
Whom the denizens of Hell cower, to Whom the heavenly
Virtues and Powers and Dominations are subject, Whom the
Cherubim and Seraphim praise with unending cries as they
sing: Holy, holy, holy, Lord God of Hosts.
P.    Lord, heed my prayer.
All. And let my cry be heard by You.
P.    The Lord be with you.
All. And with your spirit.

Prayer
Let us pray.
GOD of Heaven and earth, God of the Angels and Archangels,
God of the Patriarchs and Prophets, God of the Apostles and
martyrs, God of confessors and virgins, God Who have power
to bestow life after death and rest after toil; for there is no
other God than You, nor can there be another true God beside
You, the Creator of all things visible and invisible, Whose
Kingdom is without end; we humbly entreat Your glorious
Majesty to deliver us by Your might from every influence of
the accursed spirits, from their every evil snare and deception,
and to keep us from all harm; through Christ Our Lord.
All. Amen.
P.   From the snares of the devil.
All. Lord, deliver us.
P.   That You help Your Church to serve You in security and
freedom.
All. We beg You to hear us.
P.   That You humble the enemies of holy Church.
All. We beg You to hear us.
The surroundings are sprinkled with holy water.
