A small portion of the Roman Catholic rite of exorcism; I include the Latin, because that is the language in which the process is conducted. The translation is mine:

(After fortifying himself and the possessed with the sign of the cross, let him place the tip of the stole on his neck and with his right hand placed on his forehead, continuously and with great confidence say the following:)
(skipping a few lines)
Exorcizo te, immundissime spiritus, omnis incursio adversarii, omne phantasma, omnis legio, in nomine Domini nostri Jesu (sign of the cross) Christi eradicare, et effugare ab hoc plasmate Dei. (sign of the cross)Ipse tibi imperat qui te de supernis caelorum in inferiora terrae demergi praecepit. Ipse tibi imperat, qui mari, ventis, et tempestatibus imperavit. Audi ergo, et time, satana, inimice fidei, hostis generis humani, mortis adductor, vitae raptor, justitiae declinator, malorum radix, fomes vitiorum, seductor hominum, proditor gentium, incitator invidiae, origo avaritiae, causa discordiae, excitator dolorum: quid stas, et resistis, cum scias, Christum Dominum vias tuas perdere? Illum metue, qui in Isaac immolatus est, in Joseph venumdatus, in agno occisus, in homine crucifixus, deinde inferni triumphator fuit.

I exorcise thee, most vile spirit, every onslaught of the enemy, every apparition, every legion, to uproot thyself in the name of our Lord, Jesus Christ, and to flee hence from the voice of God. (sign of the cross). It is he himself who commands thee, he who ordered thee to fall from the heights of the heavens to the depths of the earth. He commands thee, he who rules the sea, the winds, and the tempests. Hearken, therefore, and fear, O adversary, foe of faith, enemy of the human race, bringer of death, thief of life, deviant of justice, root of all evil, spark of vice, tempter of mankind, betrayer of nations, inciter of envy, source of greed, cause of quarrel, bringer of sorrows: why dost thou remain and resist, when thou dost know that Christ the Lord shall destroy thy ways? Fear him, who was sacrificed in Isaac, betrayed in Joseph, killed in the lamb, crucified in man, and finally became the victor over the netherworld.

There is much, much more. For more information, consult your local library.
