one of the things i haven't talked about much directly but i think about all the time now due to my current hyperfixations on early medieval/late antique roman world bullshit is that most of the shit that i grew up associating with christianity is pretty specifically medieval shit. like, didn't exist until a bunch of guys in the medieval period (at least three to five hundred years after the death of jesus, well past the era of jesus being within anyone's living memory) started doing their own interpretations of old biblical legends.
the concept of "biblically accurate angels"? medieval. angels in general? conceptually pre-medieval but mostly medieval in what we know of the idea now. hell? medieval. satan as individual being? medieval. the ten commandments? mostly medieval, though the concept existed pre-medieval. taking communion? technically pre-medieval but solidified in the medieval era, probably. the trinity? medieval. christmas trees? medieval. church pews? medieval.
nothing is ever preserved in direct form from antiquity! nothing! it all is shaped by time!
