I would actually bust a gut if American protestantism actually lead to a re-decentralized interpretation of all the dumb shit catholics have spent the past 2 millenia fighting to centralize.
LETS GO CATHARISM! LETS GO MANICHAEISM! LETS GO OPHITES SECTARIANISM!
It's always helpful to remember that evangelicalism is a political ideology that derives its theological convictions from its reactionary, contradictory beliefs stemming from a rejection of modernity until now
So like, yeah its doctrines make no sense if you look at it from a purely theological perspective, but that's because it's never been a movement based on theological convictions. It's a movement that defines its theological doctrines vis-à-vis American culture wars.
