Adultery I get, because it harms a third party. Homosexuality is exactly the sort of thing I was talking about, though. Why should God care, particularly? It doesn't seem contrary to the New Commandment, does it?
I don't see why it should be considered binding when pretty much everything else in Leviticus we ignore.
There are two parts of the Mosaic Law. one is ceremonial and dietary and the other involves morality such as described in the Ten commandments which tell us not to murder, steal, lie, etcetera. The ceremonial aspect of the law, which involved offering of animal sacrifices, celebration of the Passover and other events, which Paul described as being prophetic shadows of the reality fulfilled in Christ, are no longer binding on the Jews and were never biding on the gentiles.
However, the moral principles of the law which prohibited adultery, murder, bearing false witness, etcetera, are all still binding and summarized in loving neighbor as we love ourselves.
Matthew 22:36-40
36 "Teacher, which is the great commandment in the law?" 37 Jesus said to him, x "'You shall love the LORD your God with all your heart, with all your soul, and with all your mind.' 1 38 "This is the first and great commandment. 39 "And the second is like it: y 'You shall love your neighbor as yourself.' 40 "On these two commandments hang all the Law and the Prophets."
That's why we have the moral law involving human relations in the NT in harmony with the moral law in the OT. The reason that the NT mentions specifics is because those behaviors were being practiced during that time and a clarification was needed in order to make sure that Christians understood that such prohibitions were still binding.
BTW
We as humans might not see how same sex sexual relations are harmful. However, please note that God designed us physically different for a specific purpose-to marry, procreate and fill the Earth. anything that goes contrary to that purpose is deemed a sin, whether it be dwelling in one city and leaving the rest of the Earth unfilled, insisting that mankind is the one to determine right or wrong, or whether it be a refusal to abide by his plan of having males and females only to have sex. If it goes contrary to his ultimate purpose for mankind and the earth, it is a sin.
“So God created man in his own image, in the image of God he created him;
male and female he created them” (Genesis 1:27).
