Judaism is not Christianity minus Jesus and Christianity is not Judaism plus Jesus - they're two very different religions with different suppositions and different foci.
I couldn't agree with you more.
However, since interpretations of certain aspects of Judaism are foundational to Christianity and since there seems to be a necessity of endlessly proving a man to have been God (to others but, I suspect, mainly to themselves) apologists often take the convenient course of defining Judaism (then and now) to suit the argument.
Again, I agree with you. What I've implied in this thread is that Saul of Tarsus is a an orthodox Jewish contemporary of Gamaliel; and that prior to his Damascus road experience/conversion he not only saw Jesus as at best a troublesome rebel, but he was persecuting Jesus' followers.
After his conversion he claimed that he was a Jew
prematurely born into the Christian epoch. That statement is important to the spirit of this thread since by making that claim Paul is implying that Gamaliel's Judaism is fully intact after Saul's has undergone a transformation.
To some extent Paul is saying that after the beginning of the Church, the Judaism of Gamaliel is completely intact. There are now, at that point, two unique epochs neither of which is dependent on, nor an epiphenomenon of, the other (btw, I have Rabbi Jacob Neusner's,
Jews and Christians: The Myth of a Common Tradition, at arm's length though I haven't yet read it having just finished his,
A Rabbi Talks with Paul).
One of the claims of this thread is that whereas Paul was one of the Jews whose Judaism got transformed or transmogrified into Christianity, therein making Paul no longer a Jew in the sense of Gamaliel (Paul's transformation spit him out of Judaism proper), Daniel Boyarin's understanding of Judaism and Christianity appears to be something different than Paul's. Daniel Boyarin appears to be something Paul may have longed for with all his might, but never saw since it wasn't time: a Jewish understanding of the legitimacy (the truth-content ---the spirit) of the two epochs (Judaism and Christianity) that doesn't transform or transmogrify the Jew into a Christian ala Paul.
The Christian orthodoxy that acknowledges the total legitimacy of Judaism as another epoch independent of Christianity states that after the Rapture (resurrection of the Church) the Christian epoch is complete such that there will never be another Christian added to that corporate body. At that point, God will be manifest to all the world, Jew, agnostic, atheist -----and Messiah will arrive as expected in Jewish thought, such that precisely what orthodox Judaism taught, teaches, expects, and hopes for, will have arrived, post-term perhaps, but arrived nonetheless.
The Christian epoch is what Col. R.B. Thieme Jr., called the "dispensation of intercalation." Technically it has nothing to do with Judaism, is foreign, and utterly distinct, like something inserted where it doesn't belong, and which has an expiry date (the Rapture) after which normative orthodox Judaism will be completely back on track with the arrival of Messiah. Christianity, the epoch of intercalation, will have been utterly and completely removed from the Jewish calendar and Jewish reality.
Except, that is, for what this thread is about. The revelation given to Judaism at the Rapture of the Church, which, though it doesn't transform normative Judaism into some other epoch, acts as something like the mezuzah into the Kingdom age Jews have been longing for for millennia.
The claim at the heart of this thread is that Daniel Boyarin isn't a Christian, and yet knows what every person will know after the Rapture of the Church. In this sense he, like Paul, is prematurely born, not into the Christian epoch (ala Paul), but into the post-Christian epoch (that's not here yet): he's a Jew through-and-through; but with knowledge no Jew can possess and still be a Jew (rather than a Paul-like Jew-become-Christian) until after the Rapture of the Church.
If this is correct, its stupendousness is two-fold. One, it targets one of the most important thinkers alive (and maybe there are more than one), and two, it implies that Judaism's messianic-age is upon us; we're right at the gate, at the mezuzah, into the Kingdom age -----so close, in fact, that Boyarin, at least, has already kissed the mezuzah; a practice that will be required in order to be present when the King kisses his bride (Psalms 2:12).
