but it's in the stars themselves ...
Instead of just repeating some cryptic allusions to give yourself the sheen of wisdom, how about actually spelling out what you're talking about here?
"si tacuisses, philosophus mansisses"? If you had kept your silence, you would have stayed a philosopher?
It's easy to hide behind cryptic innuendo, and pretend to be intensely knowledgeable and insightful. But unless you manage to put some substance to those claims, it's all so much razzle dazzle, and doesn't really fool anybody.
FWIW, the motif of a sacrificial deity restoring cosmic order precedes Christianity by many centuries, and does not have its origin in the realm of Abrahamaic monotheism. Gerard Genette has raised an interesting hypothesis that explains the underlying psychological "logic" of ritual sacrifices and the way it is tied to the rise of the first cultures (cf. Genette, Violence and the Sacred). It's also quite easy to find analogies to the divine sacrifice in the natural world: plants must seemingly perish in the fall and lie dead in winter, but come spring, they rise again from the underworld, renewing the world. The sun "sets", travelling through the underworld, only to reappear each morning. Or, to include something that wasn't known to our ancestors, suns themselves are the matter generators of the universe, birthing the possibility of life in their death throes as they gradually consume themselves. We are star dust, all of us.
Nothing of that points to the exclusive validity that Christianity claims for itself, though. It merely seizes upon motifs that are a part of the common spiritual heritage of mankind.
