That’s cool! I like reading about the history of the development of religious thought and currents too. It helps me contextualize how we at least narrowly understand religious ideas. For example, how Judaism (and consequently Christianity and Islam) became monotheistic and how we now rationalize pre-monotheistic Judaism to suit the fundamentalist idea that it was always that way. I am religious but it helps understand how these ideas formed and its flaws and space for interpretation. But I kinda stopped reading too much into the historical X-person, for the most part so much is conjecture. Is there a book you like?
hi :)
