i don’t think “actual Christian” is a meaningful demarcation. There’s no basis to claim one side or the the other of any schism was correct. various christians have wildly different ideaas of what they think god is, even within denominations.

most of them practice american civil religion which is syncretic merging of cultural background radiation jesus and founding fathers worship. A whole bunch of them believe god communicates with them, but that’s on a spectrum from vibes to whatever the hell is wrong with michelle bachman.
