Again, that's not really up to you. Saying "period" doesn't matter as it's easier to dismantle a monster of your making.

Maybe read some early stuff that never made the canons as you would an novel anime, may be easier as they carrier less weird baggage and are often just as good, if not better, than those that did. Harry Potter is the new virgin magus messiah touching death to save the world for the masses that don't want to go to masses, it's fine but it's far worse than the OG stuff imr.

I gather you are not aiming to, but you are playing the game and fervently evangelizing for some novel, likely US protestant strain of the Nicene machine, on the socials as the true Christianity and everything else as heresy. Consider not doing that.

Consider the dead Christians, the heretics, those that were tortured and burned or had their works condemned and names dragged though the mud for coming on 2000yrs now. Basildes was pushing some cool Christian memes long before 'believe in the bible' would go viral for example and they had to start burning Diatesserons by the hundreds, but this kinda stuff has always been there.

Calling the bible 'an insane book' makes me think you are not overly well versed here, at basic 'the bible' is a rather vast and varied collection of texts that have been in flux for millennia and how one works with these traditions is very much open to interpretation, and inspiration . The Tewahedo canon or the First New Testament might be worth a peek for a gentle intro.

Assuming you are somewhat familiar with the scriptures I suppose the big question is what did you expect when heading into, presumably modern re-imaginings in English, sacred histories, theology, philosophy and scripture from ~3rd century BCE to 3rd century CE? Is the entire period of literature insane in your reading or just the few scraps that made into the protestant canon that stand out, or.....?
