Exorcism
In Christianity, exorcism is the practice of casting out demons. In Christian practice the person performing the exorcism, known as an exorcist, is often a member of the Christian Church, or an individual thought to be graced with special powers or skills. The exorcist may use prayers and religious material, such as set formulas, gestures, symbols, icons, amulets, etc. The exorcist often invokes God, Jesus and/or several different angels and archangels to intervene with the exorcism. Protestant Christian exorcists most commonly believe the authority given to them by the Father, Son, and Holy Spirit (the Trinity) is the source of their ability to cast out demons.
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.
