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.
Mark 1
There were several people who were claimed to have the ability to perform exorcisms in the ancient world and many ancient opponents of Christianity dismissed Jesus as just another magician. Most descriptions of exorcisms at the time tended to involve the exorcist tricking the spirit or demon into leaving the victim by convincing them the exorcist had more power than the being, not a method Jesus employs. Parallels in Hellenistic cultural stories of exorcisms differ in that they usually involve an associated disease, which is not the case here. John P. Meier sees a clear distinction between these incidents and descriptions of magicians at the time.
