I’m referring to the theologians who have denied the literal existence of God, or at least the concept of a personal god who might intervene on our behalf, without explicitly rejecting Christianity. You could also lump deists into this group.

I see what you mean. I just... don't see a lot of political mileage in Deism. The idea of the Clockwork Deity is interesting to theological academics, but not terribly inspiring for activists or revolutionaries.

And side note, there’s an interesting figure from the Episcopal Church’s history named William Montgomery Brown. He made his name as a bishop publishing his pro-segregation views, which angered some northerners but was generally seen as okay, and then he found Marxism and developed a more materialist view of God as a symbol, which led him to become the first bishop in America to be tried for heretical teachings. Luckily for him, he got bids from the Russian Orthodox Church and the Old Catholic Church, neither of which considered his teachings to be heresy I guess? And because the Episcopal Church considered these churches to be valid, they couldn’t take away his role in the apostolic succession.

As a bishop, he renounced his views on segregation and took up the cause of anti-racism at the pulpit. He published a book called Communism and Christianity (which I haven’t read), followed up by Teachings of Marx for Girls and Boys (which I also haven’t read but goddamn that is a funny title).

That's cool as hell. But I'd consider it more of an exception than a rule.
