I don't know if I'm missing something, but as far as I understand it bishops have essentially been converted into normal barons, able to marry and inherit. Same goes for "holy" warriors, to which I believe one couldn't even send their courtiers in the first place, without additional mods.
I was wondering if it's necessary to completely eliminate both concepts, because let's face it, they're really useful when trying to stop imbecile dwarfs with a harelip and a lisp from taking over. Not to mention, the idea of some celibate, medieval professor, scientist or soldier dedicating their life to the intellectual/technological prowess and defense of the realm sounds pretty cool to me.
