I hope somebody will jump in here with a more adequate answer, but my short take is that the laws of the OT are of three kinds:

• ceremonial law (like, how to conduct animals sacrifices in the Temple);
• customary law (often geared toward strictly rejecting customs of their gentile neighbors, namely what they ate, how they dressed, what kind of festivals they kept) and
• the Eternal Moral Law, which is best summarized in the Ten Commandments (reiterated strongly by Christ Himself in the NT) and made even more succinct in the Two Great Commandments (Love God with your whole heart, and your neighbor as yourself) --- also repeatedly affirmed by Christ.

Thus the OT laws pertaining to Temple sacrifice, ritual uncleanness and so forth are set aside in the NT; the ritualized differentness, centered on "keep apart from the gentiles" laws are set aside because the Jewish and Gentile communities are to be made one in Christ; and what remains are he Eternal Moral Laws, which will remain forever.

Make sense?

As I said,I hope somebody else will jump in here and say more. Im sure there has been plenty of controversy about which sort of law is which. For instance, the so-called Gay Christian movement illegitimately claims that the prohibitions of deviate intercourse are just a ritual customary law, whereas Christianity ha always --- for 20 centuries now --- taught that it is part of the Eternal Moral Law.

“...my short take is that the laws of the OT are of three kinds...”

I have never heard about the 3 categories of laws. Thanks. I am comfortable with Christ’s coming and fulfilling the prophecy and righting direction of mankind. I have heard many Christians say, “Live by the OT, die by the OT”. As if the OT was replaced by the NT. I do think, however, that if the laws of the OT are meant for the stability of society, then they must remain enforced.
