The Bible: A Moral book?!

[Neo-Scholastic]

Most of the 'goodness' taught by the Jesus character, however, is common to nearly all cultures. The Golden Rule is not of biblical origins.

So are you saying a purely secular golden rule is a rational foundation for morality? A strong case could be built for that position, but you have not done so by appealing to civilization and culture. The golden rule works generally well for relations between rational adults of equal status but has nothing to say about the moral responsibilities we have to ourselves, non- or semi-sentient beings, the insane, or vulnerable populations, like the unborn or the mentally retarded.
