Don't forget the time in between both OT and NT. It was the 400 years when nobody did absolutely anything.

As for Jesus saying to the people "give onto god that which is god's and give onto Caesar that which is Caesar's" we have a major problem. No self respecting Jew of that era thought that Caesar had a claim to anything.

The new testament was spun for a Roman audience. The Easter story is a prime example. It takes place at Passover. This is a highly politically charged time for the Jews. Many years ago I celebrated this festival and as you may know, it tells the Exodus story. For jews, it is rather like the 4th of July. Culminating in a prayer that says "Next year in Jerusalem". Even Jews who live there say this prayer. So imagine if you will, an occupied land at a time of great nationalist fervor. Add to that a legend of a messiah. One who will free Jews and give them back their homeland. Great steps were also taken to make sure that JC ticked all the right boxes. An ass was provided for his entrance etc. Small wonder that Romans wanted him gone and so they crucified him, as was their way. If the Jews had wanted this? they could have easily charged him with blasphemy and stoned him to death. No, it was a political act but this is glossed over to such an extent that that Christians have been antisemitic for millennia now

the romans were the early-middle middleman in the deal. popes and then the british kings tweaked it even more. but before the romans, there was paul, and paul invented the beginnings of christianity as we know it, and if he had gone anywhere but to greece things might have worked out somewhat differently. first of all there is an old jewish expression -- yes, THAT old -- "he's a real son of god!" that just refers to a pious person. the greeks, on the other hand, had in their religion real sons of gods, gods who raped human women who then produced demigods. so that is how the greeks understood paul's statements about how good jesus was. second of all, tourism wasn't going to be greece's economic mainstay for a couple millennia, so they were supporting themselves raising pigs and fishing, and half of what they fished for wasn't kosher either. they were NOT going to convert to judaism! (cut my WHAT off? are you KIDDING?) so paul had to decide which was more important: converting the greeks to judaism, which is against jewish law anyway (jews are not permitted to proselytize!) or make the greeks goofy for jesus. he chose the latter. christianity is born! and by the way, the greeks went and called this new god a "christ," which does mean savior but savioris not an accurate translation of messiah. the messiah was never meant to be a savior. that's not a jewish concept at all. in judaism one is responsible for one's own sins. the messiah was prophesied as a human king who would bring peace (not an apocalypse, for example) in his own time (not after being killed on purpose so he could be resurrected and then vanish and then everyone could try to guess when he was coming back and make bumper stickers guessing what he would want them to do in the interim). now, you may say, jesus may never have existed, and surely did not exist as portrayed at any rate. of course! but that makes no difference to disciples, apostles, emperors, popes, kings or american evangelicals.

In all fairness to the readers of the bible; that book is so poorly written, confused, and rife with iron age ignorance it's by random chance alone that it gets anything right at all.

To understand the Christianisation of Rome it is necessary to understand Paul’s mission to convert Gentiles to the faith. Rome was the centre of the world. What better way to get your movement going. It took quite a lot of years but is pretty prolific by C2nd.

History is rewritten by the victors. Hence the old testament, the new testament, and then, in parts of the Southern Roman Empire, the Koran.
