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
The expression minor exorcism can be used in a technical sense or a general sense. The general sense indicates any exorcism which is not a solemn exorcism of a person believed to be possessed, including various forms of deliverance ministry. This article deals only with the technical sense which specifically refers to certain prayers used with persons preparing to become baptised members of the Christian Church. These prayers request God's assistance so that the person to be baptised will be kept safe from the power of Satan or protected in a more general way from temptation.
