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.

In 1985 the ministry of exorcism was first introduced to him when he encountered a woman who was a third generation satanist. From then on he ministered to people with spiritual oppression. He said of exorcisms that, "when one experiences it face-to-face -- when one sees evil, smells it, feels it, has things thrown in his face, encounters evil prowling around like a lion -- then you know there's a spiritual warfare going on all around us."
