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.
Minor exorcism in Christianity
Today, in some provinces of the Anglican Communion, the "Anglican liturgy does not involve an explicit exorcism or rejection of evil, but does including a signing with the cross and the wish that baptism delivers one from "the powers of darkness." Others, such as the Anglican Church of Tanzania, however, provide for anointing and consignation that accompanies "the exorcism that follows the examination of the candidates".
