To our esteemed OP:
I made a joke a few years ago, on these very forums, that you can charactereize Christianity as the ultimate Jewish plot intended to undermine and destroy the pagan Roman Empire.
Seems to have worked, yes?
Well,
sorta.
The purpose of virtually all of those small Jewish sects at the time was to destroy the Roman Empire and end up with a world with them at the top. None of them really worked, because they were all the kind of pencils-up-the-nose underpants-on-head retarded plans that you get if you base real life plans on a fairy tale and the kind of intellect who'd find secret recipes for such a plan in a text that plainly says something else.
You know, the "oooh, god says you have to wash after touching the bed of a menstruating woman, therefore god likes clean people, therefore if we wash lots and lots and be squeaky clean, god will like us lots and will come and kick the Romans' ass for us" kind of retarded plan. It's not even a joke, they had literally dozens of "baptist" sects doing their best to enact that plan.
And others, of course, took the ever popular "maybe if we murdered everyone who doesn't believe in the EXACT same nonsense as us, or doesn't act EXACTLY like we want them to, then god will see we're really really devoted fanboys and come kick the Romans' ass for us" kinda plan.
Meanwhile abroad, out of the reach of the local theocracy, even more radical, proto-gnostic finding secret meanings in the Tanakh was happening. E.g., Philo inventing a whole second god, because a sentence in Genesis was in the third person in his hand-copied copy of a copy of a copy. And none of those worked either. There was no secret knowledge that would get the secret god to kick your enemies' ass for you.
Ironically enough, the sect that actually did have an impact on the Roman empire, really didn't seem to have that as its main goal.
Now don't get me wrong, a lot of these were slaves and underprivileged folks, and they would have liked nothing more than seeing Jesus come down and lay down the smack on the Roman Empire. And a lot even fantasized about it or had visions about it. See, Revelations.
But there is also evidence in the text that they took a lot of steps to distance themselves from those rebellious Jews. E.g., Joseph and his pregnant wife not only complying with a census (which the rest of the Jews had a serious religious problem with), but even with a ridiculous requirement to travel tens of miles across broken mountain terrain for it, is such a hint at being good Roman subjects.
It also had an impact because it dropped the whole rabid xenophobia that was the base of the others' hatred of the Romans. Paul from the start opened it to everyone.
So, anyway, ironically enough, the ones who had an impact were the ones who DIDN'T plot to bring down the Roman Empire.
