Sorry, I know it's stupid, but I have to mention the big, pink elephant currently in the room:
I doubt all Christians would agree with that creed? Are we saying all Christians have a common, core belief in "the holy Catholic church" and the "communion of saints"?
Good question Awakened. The question becomes: Who gets to define what Christianity is? The JWs say that they are the only "real" Christians, all the others are "false".
After all, a big pink elephant might call itself a small purple mouse, but it does not make it so.
