Demon
The contemporary Roman Catholic Church unequivocally teaches that angels and demons are real beings rather than just symbolic devices. The Catholic Church has a cadre of officially sanctioned exorcists which perform many exorcisms each year. The exorcists of the Catholic Church teach that demons attack humans continually but that afflicted persons can be effectively healed and protected either by the formal rite of exorcism, authorized to be performed only by bishops and those they designate, or by prayers of deliverance, which any Christian can offer for themselves or others.
Gabriele Amorth
Amorth was also interviewed for the second episode of "True Horror with Anthony Head", presented by Anthony Head. He explained he would never perform an exorcism based solely on someone's claims of possession; always directs people to psychiatrists and doctors first, and that when he sees someone is not possessed but the person still insists, he replies: "You have no devil. If you have a problem, talk to a good vet."
