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.
Exorcism in Christianity
It includes singing praise and victory songs, reading from the Scripture, prayer and confronting the spirit in the name of Jesus. Dialogue with the spirit is another important part of the exorcism ceremony. It helps the counselor (exorcist) to know how the spirit was operating in the life of the demoniac. The signs and events mentioned by the spirit are affirmed by the victim after deliverance.
