Exorcism
In Christianity, exorcism is the practice of casting out demons. In Christian practice 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. Protestant 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.
Exorcism in Christianity
The Lutheran Church traces the practice of exorcism to the Scriptural claim that Jesus Christ expelled demons with a simple command (Mark 1:23–26; 9:14–29; Luke 11:14–26). The apostles continued the practice with the power and in the name of Jesus (Matthew 10:1; Acts 19:11–16). Contrary to some denominations of Christianity, Lutheranism affirms that the individual, both the believer and the non-believer, can be plagued by demons, based on several arguments, including the one that "just as a believer, whom Jesus Christ has delivered from sin (Romans 6:18), can still be bound by sin in his life, so he can still be bound by a demon in his life."
