I'm hearing more and more condemnation of the concept of the 613 commandments found in the Torah. First of all let me say that it's only what are called the Orthodox Jews keeping them. Not the non religious and not I don't think the average "Reformed" or "Conservative" Jew. Very few Christian leaders are encouraging keeping the 613 that I know of. Only some 6% of Jews are Orthodox.
It was Maimonides who came out and accounted for the 613 number and he lived a long time ago. Nobody is supposed to keep all 613 of them. One reason not is because some deal with priests in the physical temple and since no physical temple exists it is not possible to perform them.
Jesus however did. He lived when there was a temple. Early Christians also did live when there was a temple and in the early book of Acts we see them going to the temple and keeping the law as did Paul who was involved in keeping and paying for others to keep the Nazarene vows.
It is Jesus who says he who teaches keeping the least of the commandments will be great in the kingdom. He teaches the spiritual keeping of the commandments not just the letter of the law. For example lusting after a married woman is discouraged. Hating someone is murdering them in your heart.
So I'm not so convinced that the bride of Christ should be condemned from having a interest and knowledge and keeping where appropriate the commands of the Torah. We are told in the Bible that the law shall go out from Jerusalem and a Gentile will grab hold of a Jew and demand he teach them some Torah.
How can we know what sin is if we do not have the commandments?
