Exorcism in Christianity
Exorcism in Christianity is the practice of casting out demons from a person they are believed to have possessed. 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. A survey of Christian exorcists found that most exorcists believe that any mature Christian can perform an exorcism, not just members of clergy. 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.
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".
