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
Historically, Taoist exorcisms include chanting, physical movements, and praying as a way to drive away the spirit. Rituals such as these occur during festivals. Rituals such as these are considered of low order during these festivals. They are more for entertainment than a necessity during festivals.
