Ya sure `bout that? The text of "The Law" (aka Torah) indicates most of laws are given in the form:
And Yahweh said to Moses " law law law law law".
Sure looks like they are not just claimed to be divinely inspired, but divinely dictated.
This is gonna get a little more involved than I would've liked, but you're a smart guy, so hopefully your ability to follow along is better than my ability to explain.
Scholars may argue about the exact number, but I'm actually willing to grant you that God personally dictated all 613 Mitzvot commandments... because it doesn't make any difference.
The question isn't about their source, it's about why they are what they are. Since I'm admittedly not a biblical scholar, I'm also not an expert on the Torah, so as always, take this with a grain of salt.
In agreement with Christianity the Talmud teaches that there were two sets of Ten commandments, but that the first set, which was carved by God himself, was later destroyed, and that the second set was carved by Moses in corroboration with God. Supposedly the first set was destroyed because men were incapable of keeping them. Thus the second set was created with a direct eye on the traditions of men. Because only then could men be expected to adhere to them.
Which is why Jesus says that it was only because of the hardness of men's hearts that Moses allowed them to put away their wives. It's also why Jesus says that whosoever looketh on a woman to lust after her has committed adultery with her already in his heart. But that commandment would've been too hard for men to keep, and so the 613 Mitzvot commandments were written not with God's divine inspiration in mind, but with men's flaws.
Christ then gives us just two commandments, without any clarification about how to keep them other than the story of the good Samaritan, and the admonition that whatsoever you do unto the least of these, you do unto me. We then mistakenly believe that if we keep the 613 Mitzvot commandments that we will by default keep Christ's commandments as well, but that's simply not true.
The priest and the Levite may have been really good at keeping the commandments, but that doesn't mean that they loved their neighbor, conversely in loving his neighbor the Samaritan demonstrated that the laws were moot. He had accomplished by nature that which the law couldn't accomplish by obedience.
The problem may have been that the priest and the Levite mistakenly used the commandments about ritual impurity to unknowingly avoid Christ's commandment to love thy neighbor. Sadly, that seems to be what people such as
@Servus are doing today, using the commandments against homosexuality in order to circumvent the commandment to love thy neighbor.
Okay, after rereading it I must admit that that's a muddled mess, but I haven't got the time nor the patience to rewrite it. So as before, if you have any questions, just ask, maybe I'll answer, and maybe I won't.
