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
Bruner begins experiencing supernatural phenomena at home, waking up at 3:00 a.m. to the smell of burning material. Moore warns her she may be a target for the demons, revealing he too has experienced similar phenomena on the night he was preparing the exorcism. With the prosecution building a strong case, Bruner steps up her own by trying to legitimize Emily's possession. She summons anthropologist Sadira Adani to testify about the beliefs about spiritual possession from various cultures, but Thomas dismisses her claims as nonsense. Graham Cartwright, a medical doctor who attended the exorcism, gives Bruner a cassette tape on which the exorcism was recorded.
