Demon
The contemporary Roman Catholic Church unequivocally teaches that angels and demons are real beings rather than just symbolic devices. The Catholic Church has a cadre of officially sanctioned exorcists which perform many exorcisms each year. The exorcists of the Catholic Church teach that demons attack humans continually but that afflicted persons can be effectively healed and protected either by the formal rite of exorcism, authorized to be performed only by bishops and those they designate, or by prayers of deliverance, which any Christian can offer for themselves or others.
Exorcism in Christianity
For example, in one particular situation, a Roman Catholic woman believed that her house was haunted, and therefore consulted her priest for assistance. Since he was not available to drive the demons from the woman's home, she contacted a Methodist pastor, who exorcised the evil spirits from a room, which was believed to be the source of distress in the house, and celebrated Holy Communion in the same place; following these actions, there was no longer any problem in the house. In another situation, The Reverend Jay Bartlett writes that a young lady who was involved with "drug abuse, self mutilation, severe abuse, mental torment, Satanism, occult activity, communion with demons, and other evils" was exorcised at Mt. Olive Free Methodist Church in Dallas over a period of seven nights, with "anointing oil, the Word of God (the sword of the Spirit), holy water, the sacred symbols of the cross, the blood of Christ, and consecrated materials [being] utilized to drive out the demons."
