Paul of Tarsus.
He "hijacked" the reported teaching of the JC, who was merely trying to be a good / devout Jew, to create Christianity.
Combination of things, but mainly the bible itself.
JC was very well educated in Jewish religion, debating with priests at a v young age, and throwing out shops from religious buildings.
He surrounded himself with ordinary (untarnished) people some who were zealous for their Jewish religion (Simon the Zealot) and threatened the religious hierarchy of the day who had allowed this slippage.
Paul himself was extremely hostile until his Damascus moment. The latter sounds like he realised that the best way to fight was from within.
Clearly there is a lot more
None of the above!He will be genetically modified and you will know when you see him!The world will muse in awe!!!
The biblical mention of the Antichrist was a veiled jab at emperor Nero.
