I seriously doubt that you are a Talmudic scholar on par with the Jews or even a Torah scholar. I doubt that you have even seen how Jews study in a Yeshiva and know the level to which they dig, having to know the original languages so that they don't need to depend upon a flawed translation. They have lived and breathed Torah and Talmud since the day they were circumcised. Quite frankly, you just haven't put in the time. I think you have a lot of chutzpah to think you have a right to judge.
And you still haven't dealt with Deuteronomy 17:8-13 (much less Matthew 23:2 and Matthew 23:23).
The Jews put in oceans of time into those things, and yet they reject the Son of God. I don't question their intellect, but their judgment is manifestly flawed.
The Jewish law is the Jewish law. The Torah law was not Jewish law, it was God's law. The Jews interpret it, and interpret it and interpret it. And in their interpretations, they depart from what it says. The calf and the mother's milk are a classic example.
It doesn't matter in the end to me anyway, other than the fact that Christians get snared in a law that never applied to them and start saying and doing silly and bad things - like burning witches or killing Jews, for instance. After all, it is the law of Torah that compels the execution of blasphemers, and given that Jesus was in fact the Son of God, when Jews deny that are they not blasphemers, and therefore subject to the death penalty (by stoning) under the Torah? Of course!
Problem: non Jews are not in positions of authority, under the Torah, to carry out such a sentence - that law was for Jews, not for Gentiles. And Jesus certainly didn't give anybody the authority to kill anybody for blasphemy.
In the end, one cannot hold up the Jewish scholarship about the law as "authority" in the absolute - they lost that authority when God tore his way out the Holy of Holies and then tore the Temple down to the ground. But in terms of cultural authority within the world of Jews, of course, the authority you cite is supreme.
And since I'm talking to a Jew - you - of course that is where you're going to place your trust.
I wonder how you square the fact that these same authorities whom you vaunt for their authority in such matters with the fact that they reject the Son of God and consider him to have been at best a deluded soul and at worst, a blasphemer.
But I'm not really all that curious about it.
