But who are these modern day Jews and what linage are they claiming?
The Christian Bible portrays a very precise picture of ancient Judaism during the Roman Occupation. It portrays the Pharisees as being in Charge of the Jewish Temples and being the Jewish "Chief Priest". They were clearly recognize by the Jewish culture well enough to be the ones who interact with the Roman Authorities.
But the "Modern Day Jews" want no part of being associated with those pharisees and Jewish Chief Priest who were in charge of the Jewish Temples.
So who do they lay claim as their ancient lineage of Judaism?
They certainly can't lay claim to being followers of Jesus. Moreover, Jesus himself was protesting against Orthodox Judaism. Not only that but the information we have concerning Jesus has Jesus supporting every jot and tittle of the Jewish Law which Modern Jews refuse to take literally.
So if they can't lay claim to having a lineage to Jesus, and they refuse to have lineage to the Pharisees, (a form of Orthodox Judaism that no Modern Day Jew would support) then who exactly do they claim as their lineage to these ancient times?
I don't see where they have a well-defined group to identify with even back to the days of Jesus much less beyond that to the days of the Torah.
So where is there any merit in their claim to have cultural lineage clear back to the Torah?
Who are these people?
They can only have been a more modern day uprising. And therefore they cannot lay claim to being able to speak to the issue of what "ancient Jews" might have actually believed.
They certainly have no business trying to lay claim to the Torah as "Their Scriptures" like as if they have some special connection to those ancient cultures.
The Modern Day Jews aren't anymore closely related to those ancient Jews than most other people. And certainly not in terms of how they believed. It's pretty clear from the actual writings in the ancient scriptures that the authors of those scriptures believed they spoke for some God. They either believed it, or fraudulently claimed it to be sure because that's what's actually written in those scriptures.
The Modern Jews apparently don't like what is literally written in the ancient scriptures and would prefer to imagine alternative "non-literal interpretations".
But where is there evidence for any lineage back to any actual ancient groups that felt that way?
Even Jesus demanded that every jot and tittle of the scriptures must stand until heaven and earth pass.
The Pharisees were also pretty obviously quite hard-nosed about demanding that laws be upheld. So much so that they called for the crucifixion of Jesus on charges of blaspheme or apostasy.
So who do the modern day Jews claim as their ancestral group?
And why wasn't that group even mentioned in Christian theology?

Where are the records that document how this unknown group actually believed?
I personally don't see where the modern day Jews even have a claim to any direct linage to their own past in terms of this specific religions paradigm.
If they can't claim the Pharisees, and they can't claim Jesus, then who's left to claim? Some lesser-known obscure group?
If that's the case, then where is there any merit in claiming a strong lineage clear back to the days of the Torah. Obviously if modern day Jews were nothing more than a lesser-known off-shoot of the Orthodox Judaism of the Pharisees then they can't lay claim to being strong enough to reach clear back to the Torah in terms of scriptural "authority".
Question for Debate:
Who exactly do the Modern Day Jews claim to be decedents of in terms of claiming the rights to "Religious Scriptural Authority".
My position is that they have no credible claim that can be dated back to the Torah. In fact, I can't see where they have any credible claims dating back even to the time of Jesus.
