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
Moore is called to the stand where he plays the tape. As seen in a flashback, Moore, Emily's father, Jason, and Dr. Cartwright participate in the exorcism while her mother and sisters pray in the living room. During the Lord's Prayer, Emily attacks, causing the family cats to become agitated and attack Moore. As Jason and Cartwright help Moore, Emily escapes from her restraints, leaps out of a window, and flees to the family barn. The others give chase, Moore continuing the exorcism and demanding to know the demon's name. It responds by revealing there are six demons – those who possessed Cain, Nero, and Judas Iscariot, a member of Legion, Belial, and Lucifer himself. The exorcism abruptly ends when the men render aid to Emily's father, injured by runaway horses. Thomas reasons that Emily's behavior can be explained by learning ancient languages at school and her epilepsy.
