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.
Minor exorcism in Christianity
Today, in some provinces of the Anglican Communion, the "Anglican liturgy does not involve an explicit exorcism or rejection of evil, but does including a signing with the cross and the wish that baptism delivers one from "the powers of darkness." Others, such as the Anglican Church of Tanzania, however, provide for anointing and consignation that accompanies "the exorcism that follows the examination of the candidates".
