So I'm right, he never said a damn thing about homosexuality. That's all you had to say. In the passage you're referring to, he was actually being the original feminist and was talking about divorce and how guys shouldn't just shuck off a chick when they're bored with them. He wasn't even thinking about the gays.
Still engaging in legalese to excuse your behavior I see...OK..whatever lets you sleep at night. However, here are the facts:
1) Jesus did not come to abolish the law, but fulfill it. There were dimensions of the Jewish law that do not carry over into Christianity. But Christ told us He fulfilled the law, not reneged on it. As He explained, He heightened its morality (Matt 5:17-20); fulfilled its signs, made good on its promises and gave substance to its shadows (Luke 24:46-47). He did not come hat in hand conceding that Old Testament God was backwards and uninformed. Leviticus says that God finds homosexuality detestable (Lev 18:22). God did not change, morally, in the New Testament. What God finds detestable one day He does not suddenly find agreeable the next. Now, if anything, Jesus says, we have a morality that now supercedes, and not contradicts, the moral law (Matt 5:17-21). Certain ceremonial shadows and social codes were fulfilled in Christ, but He did not, in any way, come to revise the God behind the law.
But why, you ask, didnt Jesus speak directly against homosexuality? Simply put, He assumed the moral tenets of the Mosaic law, as did the people He spoke to. He also didnt directly speak against bestiality, genocide, child molestation, or gang rape because these things were assumed, based on the Mosaic Law, to be sinful. You cannot separate His teaching from its Old Testament backdrop. His every word, He said, has its anchor and meaning in the Old. It is true that Jesus said that the Great Commandment was to love God and love others (Matthew 22:37-38) but note that He said in that same passage that that Great Commandment was the summation of the OT law. In other words, the OT law was an expression of what it looked like to love God and love others. Love God and love others was an abbreviated version of what the OT law gave in longer form.
To say that because He never mentioned it we should assume Hes ambivalent about it is the logical fallacy of argument from silence, and in this case its a really bad one that completely ignores Jesus context.
Your "legalese" could very well cost you in the long run, but go ahead and obfuscate.
