Old Christiananity was so much more interesting

Occasionally I'll read about pre-luther/pre-catholic/orthodox split and...idk, it feels like people actually cared? I mean i dont want to say modern Christians don't care about Christianity, but genuine theological debate about the fundamentals of Christianity is a lot more interesting than "noooo the pope has too much power" (I know its more than that but compared to some of the more interesting stuff like splits between mainline Christianity and nestorianism and gnostic sects etc. It's a lot less interesting).

I know I'm oversimplifing it but I wanted to say something since I dont see people really mention it anywhere
