1. There's no such "astro-Theo-logy".
Is a monster-concept, not real at all.... basic contradiction.
Either"astro-" or "Theo-" logy.
You are promoting same heretical idea, that the Creation and the Creator is the same.
You are not the same as your mother and father...
You add feces to pure water.
And I can see - most of posting is heretical "thanks" to your false concept.

2. The Sun worship was supported partially by the true, divine inspiration and many - the majority of factor near or far from the Truth.
Was easier for some people to "jump" to Christianity after receiving the Truth.
So, is not a "story" of Jesus - other blasphemy!, the teaching of Jesus cleared and purified the knowledge, made it holy.
================
Man / Woman, you're far, far from Truth.
Leave behind the lies of the anti-Christian work in literature, movies, music, [dead] arts, a.s.o.

English language do not give support to think about uniqueness, hypostasis, antinomy, ....
