No reputable theologian, or rational believer for that matter, adheres strictly to Biblical morality. As everyone knows, believers pick and choose their morality from a smorgasbord of divine commands, both good and bad, in scripture. And doing that shows that you have a sense of right and wrong that doesn't come from the Bible or God. Ergo, it comes from evolution and culture.
