If you, or anyone, can explain to me what we can do about moral corruption, I will join you in trying.
First, we have to agree on a definition of moral corruption.
I think marriage is a sacred institution that is in danger because a lack of commitment to marriage, a feeling that infidelity is okay and that divorce is just the next step in the evolution of one's life.
While we were discussing sin in church one day, there was a dead silence when someone mentioned divorce. That was because there were a lot of divorces among the congregation.
Of course Jesus never once mentioned homosexuality but he certainly had things to say about divorce.
So, I think we are in danger of consigning moral corruption to things safely out of our purview. Most of us will encounter very few gays in our life and almost no transsexuals. This is all stuff we see on television. I have a couple of gay friends, a gay niece and a gay nephew. They are all fine, moral people. I don't think anyone wants to go back to the barbaric times when homosexuals were punished as criminals. Or.... do they??
So.... give me your definition of moral corruption... and please do not include the mentally ill people who have some delusion that they are in the wrong body.
I know some of this has been addressed already, but I want to insert here that divorce, though specifically mentioned, does not necessarily involve the sin of both individuals. If a person has been a faithful husband or wife and is cheated on by a spouse, then there is no sin in his or her getting divorced.
There is no question that divorce is terrible and painful, no matter the circumstances, and is clearly not in God's perfect plan for any of us, but the guilt of both parties cannot be assumed. Many churches are engaging in more serious pre-marital counseling to prevent divorces, and there is no doubt that the problem of divorce is severe, but the circumstances vary.
As far as your greater question is concerned, there are moral absolutes in Scripture that are extremely clear. Adultery, sex outside of marriage, homosexuality, bestiality, etc. When a society abandons its moral standards, as America has done (due in large part to the "sexual revolution" of the 60's), it is destroying itself from within. (As a matter of fact, the problem of divorce has been greatly exacerbated by the "free love" movement, increased adultery, sex before marriage, pornography, etc.).
Your gotcha question about Jesus' not talking about homosexuality has been addressed. If you believe in the Trinity, and if you believe that the Bible is God's inspired word, then you also believe that everything in Scripture condemning homosexuality, is directly from Jesus, the Son, and part of the Godhead. We don't have Jesus' words condemning bestiality or incest either, but I have rarely heard the argument from anyone that Jesus must approve of those sins because He didn't mention them.
At any rate, I don't think you really want an answer to what is morality, because you have rejected it from everyone who has given you an answer.
This is (hopefully) my last response to you on this subject, because I get the sense that you are baiting and not asking out of a genuine interest in my response.......... which I am sure you will reject with your characteristic sarcasm.
