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.
The Last Exorcism
Filmmakers Iris and Daniel follow Cotton Marcus, a reverend living in Baton Rouge, Louisiana, who seeks to delegitimize exorcisms. Marcus, who lost his faith after the birth of his ill son, is accustomed to performing fake exorcisms on "possessed" individuals. He accepts an exorcism request sent by farmer Louis Sweetzer, who claims his livestock are being slaughtered by his daughter Nell; Louis suspects that Nell is possessed by Satan.
