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
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."
