During the early years of the Roman Empire, there were many different religious cults that competed for popularity. I've read about one such cult, a rather militant form of Judaism built around the teachings of a strange holy man named Yeshua. I know it's probably veering on ASB, but is there any way such a cult could have taken hold throughout the empire in the same way OTL worship of Mithras did? Would such a different religion have helped the Roman Empire prevent splitting apart into civil war by the 10th centrury, and remain united longer than it did?
