Christianity is not an astro-theological religion. Some 'philosophical' groups have interpreted that way as have the masons, but that's not what it is. They have created a working system for correlating Christianity with the macrocosm of the universe, and not all ancient cults are based on Sun worship either (many Moon worshipping cults were present in the Fertile Crescent region, themselves a bastardization of the even older astrotheology from Egypt and Chaldea).

Astrotheology was an idea in Mesopotamia where the gods were equated as the heavenly bodies. But it does not mean that the gods were actually planets. It just means that they had extremely large ego's. Golden Dawn (Aurora Aurea) rituals treat Osiris as a solar god, but that's not how ancient Egyptians saw him.

It has a fixation on Saturn which is odd as it's not the brightest object in the sky and there's no way based on accepted history primitive man could have known it produces it's own light, if indeed that is true.
