A solitary pagan practicing syncretism is not reliant on a community.
Yeah, I guess not. However, I guess I imagine that if there was a bunch of people doing it, they could hypothetically create a network based on idiosyncratic experience or belief. I don't know how they would go do that, because one wonders how they would even meet each other in numerous enough numbers, to start something like that. It does seem somehow possible though
A religious hermit does not require others and is also not mentally ill.
When I imagine the original animist priest, I often imagine a person who sort of self-isolates. And I think that the biblical characters were influenced by the notion as well, from the prophets to new testament figures.
I often seem to post about the hermit tarot card, and recently about how, if you place him next to the pope card, facing the pope, it seems they are staring down each other in a competition. The pope has disciples in his card, and the hermit has none. But if they are competing, it may suggest that there a two religious or spiritual modalities that are being debated.
