One of my favorite old-school Christian religious sayings is the term "unclean demon" because it implies that on the other hand, there must be some demons out there who ARE clean! Otherwise, why would they need to specify that particular adjective in the first place? Even though I'm a Republican voter, I'm an agnostic who's never been very good with religion in the first place. So could some Evangelical explain to me the difference between an "unclean demon" and a "clean demon"? Just wondering.
