To which commandments are you referring? Not the Ten Commandments, because "thou shalt not be gay" is not among them. Jesus never said anything about homosexuality. Paul did, but he also said some things about women that we routinely ignore (like women speaking in church.) So what does that leave except Old Testament levitical law? If we believed all of  Leviticus and treated it as authoritatively as many anti-gay people do when they cite those particular passages that target gay people we'd be stoning people to death for the sin of adultery (20:10), which includes getting divorced, according to Jesus (Mt. 19:9). 

Your talk of "objective morality as the revealed will of God" always sounds like people when they refer to the static, never-changing "deposit of faith," as though the Holy Spirit had no role to play in shaping our ever-unfolding understanding of the faith or as though revelation was something that ceased two thousand years ago. It didn't. Faith listens, learns, and evolves.
