For the life of me, I haven't been able to figure out where the following quote comes from, but it's a fun, concise description of the relationship among Judaism, Christianity, Islam, and Mormonism...
Think of it like a movie. The Torah is the first one, and the New Testament the sequel. Then the Qu’ran comes out, and it retcons the last one like it never happened. There’s still Jesus, but he’s not the main character anymore, and the messiah hasn’t shown up yet.
(adj.) wild and frenzied; from Greek κορυβαντες (Korybantes)
