I believe that people do preform exorcisms on people, but I do not believe that people actually have demons in them or are possessed by one. But yes, exorcisms are real, just not the fact that a demon is in the person's body whom you are preforming on. Just my opinion.
To some people they are real. Usually the one who is having such a thing done to them during a fundamentalist Protestant service on a Sunday morning probably do not need them, and would benefit by getting a life. (Including the "shepherd" who performs such "miracles". But hey, if such procedures make "innocent" folks think they are doing good, so be it. Who am I to mock?) Evil and dark energies and forces are very real, to me anyway, and IF such a person is possessed to the point of floating in midair without any visible means of support or having their neck do a "360" and survive, then I really do not think witnessing and/or dealing with such phenomena would be psychologically healthy for the EXORCIST(S) much less the person who is possessed by such supernatural strength! Madness which is probably a form of "demonic" possession can be contagious though. And make no mistake there are some seriously mad folks walking around. Lord knows, I have had to deal with a few "imps" and "goblins" making noise upstairs in my "attic" (head)
We are told in Scripture: "But after it became evening, people brought him [Jesus Christ] many demon-possessed persons; and he expelled the spirits with a word, and he cured all who were faring badly." (Matt. 8:16) So, Jesus did expel demons, and when this took place the person returned to a normal state of mind. That Jesus Christ and his early disciples could expel demons is a matter of Bible record. However, when certain impostors, the seven sons of the priest Sceva, tried to do this in the name of ?Jesus whom Paul preaches,? what happened? Why, the demon-possessed man seized and severely mauled them, stripping all seven of them naked. (Acts 19:13-16) So not all would-be exorcists have success, even if they use Jesus? name. True, during the infancy of the Christian congregation, Jehovah God often enabled Jesus' disciples to perform miracles under the power of His holy spirit. But such miraculous gifts of the spirit were no longer needed once it had been proved that the "hand of Jehovah" was with the followers of Jesus Christ. (Acts 11:21) Consequently, the miraculous gifts of the spirit and unusual demonstrations of its power passed away.-1Cor. 13:8-13.
The Roman Catholic Church’s Code of Canon Law permits authorized ministers to perform exorcisms. The New Catholic Encyclopedia explains: “Formerly the book used in this ceremony was the book of exorcisms; today it may be the Pontifical, the Missal, or the Ritual. The handing of the book to the candidate is the necessary action, and the words of the ordaining prelate, as indicated in the Pontifical, the necessary formula.” Did Jesus perform some special ritual in order to expel the demons? Was a séance or any form of magic employed by Christ, his apostles or his other disciples when bringing relief to the demon-possessed? No. Neither Jesus nor his first century followers possessed or used any “book of exorcism.” Moreover, nowhere in Holy Scripture does one find words, phrases or formulas that are supposed to be especially effective in expelling wicked spirits. For that matter, the use of some form of magic is not compatible with true Christianity. Jehovah God instructed his people in centuries past: “There should not be found in you . . . a practicer of magic.” (Deut. 18:10)
