Exorcism
In Catholic practice the person performing the exorcism, known as an exorcist, is an ordained priest. The exorcist recites prayers according to the rubrics of the rite, and may make use of religious materials such as icons and sacramentals. The exorcist invokes God—specifically the Name of Jesus—as well as members of the Church Triumphant and the Archangel Michael to intervene with the exorcism. According to Catholic understanding, several weekly exorcisms over many years are sometimes required to expel a deeply entrenched demon.
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.
