Straight people are freaked out by gay (to use a euphemism) relations—the same way gay people are freaked out by straight relations. Everyone fears everyone who is in some key or fundamental way truly different from them. And fear with no way out becomes anger.
So all the straight people who were Christian took their fear and anger of all the gay people they didn’t know, crammed it into the mouth of God, and called it Gospel.
As time goes by, more and more straight people are getting to know gay people, and so coming to realize that there is nothing more frightening about being gay than there is about being red-headed or left-handed.So every day Christian theology is moving a little bit further away from the terrible idea that God condemns gay people, the same way it moved away from the terrible ideas that God condones slavery and doesn’t want women to vote.
The gay “issue” is being resolved. As Martin Luther King, Jr. said, “The arc of the moral universe is long, but it bends towards justice.” Nothing has ever stopped that truth, and nothing ever will.
