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.
Deliverance ministry
Though many people confuse deliverance with exorcism, they are not the same. Exorcisms are carried out through the use of various rituals of exorcism, such as the Roman Ritual, and often utilize attendant sacramentals such as holy water, while deliverance involves the ongoing counseling of the individual through various programs.
