Exorcism
In Christianity, exorcism is the practice of casting out demons. In Christian practice the person performing the exorcism, known as an exorcist, is often a member of the Christian Church, or an individual thought to be graced with special powers or skills. The exorcist may use prayers and religious material, such as set formulas, gestures, symbols, icons, amulets, etc. The exorcist often invokes God, Jesus and/or several different angels and archangels to intervene with the exorcism. Protestant Christian exorcists most commonly believe the authority given to them by the Father, Son, and Holy Spirit (the Trinity) is the source of their ability to cast out demons.
Gabriele Amorth
He said that the new rite of Exorcism is "a farce. An incredible obstacle that is likely to prevent us from acting against the demon." He observes that the new exorcism rite forbids exorcisms on people who have been reportedly subjected to evil spells. Father Amorth exclaimed, "Absurd! Evil spells are by far the most frequent causes of possessions and evil procured through the demon: at least 90% of cases. It is as good as telling exorcists they can no longer perform exorcisms." He also noted that it also "Solemnly declares that one should not carry out exorcisms if one is not certain of the presence of the devil", while "it is only through exorcism that the demons reveal themselves". He considers the new rite, "A blunt weapon ... Efficacious prayers, prayers that had been in existence for twelve centuries, were suppressed and replaced by new ineffective prayers."
