yes it is, becase the Bible is not the bottom line for Christans, it's the bottom line for Catholics, as I said, there have been Christian sects, from before the councel of Nicea, before the Bible was cannonised, that did not think that Jesus was the son of God. these sects were, for the most part, hunted down and killed as heratics shortly after the Church gained signifigant power.
also you'r saying "nu-uh" does not refute my claim, in fact you reinforced it, Arabs are desended from Abraham, they worship the same god as him, unless you can point out in the Koran some were were Ishmael (or his desendents) refutes the god of his father in favor of a diferent one it's the same god.
