There is a spectrum between random people building ancestor shrines and the pyramid structure the Catholics have. Judaism lies much closer to organized side of the spectrum.

That’s what I said, it doesn’t. There’s no hierarchy in Judaism, at all. Except for Israel, again.

Anyway, every religion gets turned in all the ways the encompassing society wants it turn. Say, speaking of “Taoism in China” is impossible, because that’s a myriad of things, both in terms of the cult itself, and the structure, and whatever else.
