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.

The Reverend Vincent Lampert, MDiv, is an American Roman Catholic Priest and the designated exorcist of the Roman Catholic Archdiocese of Indianapolis. Father Lampert was appointed to become an exorcist by Archbishop Daniel M. Buechlien. He is one of the few exorcists known to use social media like Twitter ( @FrVinceLampert ) on a regular basis. In one article he told the reporter that he is fighting the devil by tweeting about exorcism.
