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.
Exorcist
The rite of conferral continues in societies that use the 1962 (or earlier) form of the Roman Rite, such as the Priestly Fraternity of St Peter, Society of St. Pius X, and also among groups not in communion with the current Bishop of Rome, such as the Society of St Pius V. Some believe that attainment of the position of Acolyte in post-Council practices implies ordination to the minor orders which used to be below it, such as Exorcist and Porter, although this has not been officially defined (although Canon Law section 1009 does specifically state that the only "orders are the episcopate, the priesthood and the diaconate").
