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 Exorcism of Emily Rose
During the trial, Emily's past is told through flashbacks and the evidence provided by witnesses. Presiding over the trial is Judge Brewster, with Ethan Thomas, a practicing Methodist, serving as prosecutor. The prosecution claims Emily suffered from epilepsy and psychosis to explain her behavior. Emily received a scholarship to study for a bachelor's degree but displayed signs of demonic possession after she began attending classes, experiencing visions and physical contortions. Diagnosed with epilepsy, Emily received anti-seizure medication but the treatment failed to cure her. A friend named Jason took Emily back home to her family, where she continued displaying traits of possession until Moore was summoned to attempt an exorcism.
