So how do you tell which parts of Leviticus are moral law and which are ceremonial law? I've read it, and I don't recall seeing anything which specifies.
In any case, the things that you included in moral laws are things that can be shown to cause harm to people and society (apart from the honouring God thing, since I don't, and yet I don't cause harm to society - if you disagree, please tell me how I do). But I can't for the life of me figure out how what a gay couple does in private can harm society.
The values reiterated in the New Testament. You wouldn't say we are no longer under the Ten Commandments, would you? Do you believe it's ok to steal, lie, and commit adultery now since we are no longer under law?
No. Of course not. Most are enshrined in our actual law as well as our spiritual law. Jesus and various Apostles make this very clear in the New Testament what continues.
Matthew 16:21 And behold, a man came up to him, saying, “Teacher, what good deed must I do to have eternal life?”
17And he said to him, “Why do you ask me about what is good? There is only one who is good.
If you would enter life, keep the commandments.” 18He said to him, “Which ones?” And Jesus said, “You shall not murder, You shall not commit adultery, You shall not steal, You shall not bear false witness, 19Honor your father and mother, and, You shall love your neighbor as yourself.” 20The young man said to him, “All these I have kept. What do I still lack?”
21Jesus said to him, “If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me.”
Matthew 23:23 “Woe to you, scribes and Pharisees, hypocrites!
You pay a tenth of mint, dill, and cumin, and yet you have
neglected the more important matters of the law—justice, mercy, and faithfulness.
These things should have been done without neglecting the others.
Romans 1:21-32
21For although they knew God,
they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened.
22Claiming to be wise, they became fools,
23and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things.
24Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves,
25because they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen.
26For this reason God gave them up to dishonorable passions. For their women exchanged natural relations for those that are contrary to nature; 27and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and receiving in themselves the due penalty for their error.
28And
since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done. 29They were filled with all manner of unrighteousness, evil, covetousness, malice. They are full of envy, murder, strife, deceit, maliciousness. They are gossips,
30slanderers, haters of God, insolent, haughty, boastful, inventors of evil, disobedient to parents,
31foolish, faithless, heartless, ruthless.
32Though they know God’s righteous decree that those who practice such things deserve to die, they not only do them but give approval to those who practice them.
Final paragraph above is pretty serious. If one fails to do what the Lord says, He won't strike us dead - He will let one do what he wants...and look what follows in that last paragraph! That's pretty serious. You don't see any such warnings about failing to use the correct cup or do the worship service in an order or sacrifice animals.
