The traditional text of the Roman Exorcism Ritual is based upon centuries of tradition and reflection – all of which follows the command and example of Jesus to drive out demons.
The ritual itself is long and verbose and the turbulent atmosphere of an exorcism means that it is rarely used verbatim. Exorcists, guided by the Holy Spirit, use whatever parts of the ritual, or none, that they see fit. They typically substitute favorite Psalms, Gospel readings and spiritual songs as the Spirit leads.
The most enduring section of the ritual, with roots dating back to the 3rd century, is the command to the demon and is widely used by Catholic and Protestant exorcists.
I cast you out, unclean spirit, along with every Satanic power of the enemy, every spectre from hell, and all your fell companions; in the name of our Lord Jesus Christ. Begone and stay far from this creature of God. For it is He who commands you, He who flung you headlong from the heights of heaven into the depths of hell. It is He who commands you, He who once stilled the sea and the wind and the storm. Hearken, therefore, and tremble in fear, Satan, you enemy of the faith, you foe of the human race, you begetter of death, you robber of life, you corrupter of justice, you root of all evil and vice; seducer of men, betrayer of the nations, instigator of envy, font of avarice, fomentor of discord, author of pain and sorrow. Why, then, do you stand and resist, knowing as you must that Christ the Lord brings your plans to nothing? Fear Him, who in Isaac was offered in sacrifice, in Joseph sold into bondage, slain as the paschal lamb, crucified as man, yet triumphed over the powers of hell. Begone, then, in the name of the Father, and of the Son, and of the Holy Spirit. Give place to the Holy Spirit by this sign of the holy cross of our Lord Jesus Christ, who lives and reigns with the Father and the Holy Spirit, God, forever and ever.
