I have no problem with saying that they are theologically wrong, and I wouldn't have paid a very high personal price for that belief, but I would object to any mis-representations of the the reasoning behind the errors of Rabbinic Judaism. This is the main thing here- is it ok for us to reject (and teach others to do likewise) something for reasons that are not accurate? Most people would say no. It's better to understand something properly.
I don't think there is a "complete" misinterpretation of scripture on the part of the Jews here. That's not even a scriptural perspective. There are many things that modern Judaism has right. The fact that your own mentor Dr Luther agreed with their canon is one of the points this thread has raised. He even had to learn Hebrew from them.
Here's what he said about Jewish doctrine, in relation to Romish doctrine:
"When the Jews then see that Judaism has such strong support in Scripture, and that Christianity has become a mere babble without reliance on Scripture, how can they possibly compose themselves and become right good Christians?"
Furthermore:
"I hope that if one deals in a kindly way with the Jews and instructs them carefully from Holy Scripture, many of them will become genuine Christians and turn again to the faith of their fathers, the prophets and patriarchs.
They will only be frightened further away from it if their Judaism is so utterly rejected that nothing is allowed to remain, and they are treated only with arrogance and scorn. If the apostles, who also were Jews, had dealt with us Gentiles as we Gentiles deal with the Jews, there would never have been a Christian among the Gentiles. Since they dealt with us Gentiles in such brotherly fashion, we in our turn ought to treat the Jews in a brotherly manner in order that we might convert some of them. For even we ourselves are not yet all very far along, not to speak of having arrived." (Both from "That Jesus was born a Jew", 1523)
Even Lutheran scholar John L. Loh Jr. says that Luther studied Judaism in order to get to the bottom of understanding the OT:
"Luther was also a rare theologian who could read the Old Testament in its original Hebrew (many who did translate the Bible used the Latin
Vulgate as their starting point). Luther spoke with and debated with Jewish scholars and studied the Talmud rather than burn it. He knew that to get to the essence of the Old Testament, which pointed to Christ, he had to get to the essence of God's Chosen People." From
here.
I could go on. I've been collecting quotes on this matter for around 10 years. Luther made it personal with his infamous treatise of 1543, which should go unmentioned.
My understanding of those things this thread is about is simple: Luther used the arguments of Jerome (as he knew them) to argue for the canon of scripture. Jerome got the argument for the Hebrew canon from the Jews he met in Palestine. He translated the whole LXX canon after putting up some resistance.
In those times the canon was not quite fixed, and the arrangement and order of the books was quite different than they are today, but in the end, the Reformers went with the Hebrew canon, as did the Jews well before them (especially around the time of the Masoretic text)
It's easy to see why Luther held to the Hebrew canon:
"The Hebrew language is the best language of all ... If I were younger I would want to learn this language, because no one can really understand the Scriptures without it. For although the New Testament is written in Greek, it is full of Hebraisms and Hebrew expressions. It has therefore been aptly said that the Hebrews drink from the spring, the Greeks from the stream that flows from it, and the Latins from a downstream pool." (from Table Talk)
Obviously, Luther remained faithful with the NT canon, even if he commented that one book was an epistle of straw. I don't think anyone can seriously build a case that he made judgments on the canon by himself outside of tradition.
