What if Paul never converted to Christianity, and thus, there was never the dramatic break with Jewish tradition and Jewish law which occurred in early Christianity. For example, Jewish dietary laws and circumcision are retained as part of Christianity, perhaps resulting in a religion which more resembles OTL "Messianic Judaism" than OTL Christianity.

Now, the first, obvious result is that this will make converting people to Christianity a lot more difficult, perhaps preventing it from becoming the dominant religion across the Roman Empire, and eventually the world, that it became in real life. However, on the other side, I wondered if by sticking closer to Judaism, and remaining a part of the Jewish tradition, if we might not see a lot more Jewish people joining this new movement than in OTL, perhaps with it becoming the dominant sect of Judaism following the destruction of the Second Temple (which I imagine occurring sometime under Roman occupation)
