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.
Mark 1
He then performs an exorcism on a demon possessed man. Curing people, especially possessed people, will be another major method Jesus uses in his mission in Mark. The demon recognizes Jesus as "the Holy one of God", the first time Jesus' supernatural opponents are shown to know his true identity. Jesus simply says "Be quiet, and come out of him!", healing the man with words alone. The people are amazed. This follows a path Mark often uses, that of a description of the affliction, Jesus' cure of the affliction, and then a demonstration of the cure to others. The power of Jesus' word over the demon might be Mark's way of trying to show to his audience, perhaps under the threat of persecution, that Jesus' message will overcome evil. By showing Jesus' teaching first before his exorcism Mark might be placing emphasis on Jesus' teachings as more important that any miracle he could perform.
