Yeah I went through a phase of reading biblical history when I had my faith deconstructed, and you quickly realize how many different Christianities there were. As well as the political context for why these sort of ideas were able to spread in this specific part of the world at that time in history. I think the version of the story told in Jesus Christ Superstar actually does a decent job with the structures of authority and their conflicting interests. To me Jesus was likely a very charismatic “nobody” who gained a following by expressing sentiments that were kind of already floating around, until it caused a problem for the authorities who needed to keep the peace or risk Rome intervening. Whether Jesus actually said what’s in the Bible isn’t important, we know people thought he said that stuff and that it resonated strongly with many. We can infer things about people at the time based on what they ascribed to Jesus.
A lot of these types read sci-fi dystopia books and think, “yeah that would be really cool actually.”
