Sorry Gale, He wouldn't. He would say "Go and sin no more," but he wouldn't say "Go and mock the institution of marriage that God created and ordained".
And, let us remember, Jesus is The Word, the Word made flesh.
The Word says in Leviticus 20:13 - If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination.
Seems fairly clear to me.
