Did Jesus say “Go an sin some more”? I don’t think so.
Of course it would help if modern Christendom was doing better with sexual virtue. Without upholding the entire divine model of man and wife, we end up with facades there too. When we hear Jesus say that, we have to ask how well we are trying to cooperate. It would be a feeble victory if we only got homosexuals to back off into some other form of sexual blasphemy.
