Properly speaking, God is not man’s natural end, so I don’t see how it is relevant. Otherwise thinking is an innovation of the Protestant reformers. That is generally my bone to pick with Protestant theology.
Man certainly has
a natural desire for God, but he requires grace to participate in God’s life, for God being infinitely higher in virtue than man. Knowledge of God as the only God is certainly possible and in many way demonstrable
a posteriori (again, Natural Theology), but if man refuses to encounter who he was created for by refusing to cooperate with grace, it would certainly be logical (within his understanding of options) for him to try and resort to other god-like things, such as believing in multiple gods, or trying to make oneself a god, or trying to make one’s own gods out of pleasurable attachments, etc. Now whether that’s
strictly polytheism is up for debate, but polytheism is a more organic term when we consider the idea of idolatry–and rather THOSE two terms I would equivocate.
I don’t understand what (2) has to do with any of this, but (1), that is, how order can arise from chaos, is certainly a more severe question that has haunted me from time to time. Adjacent to this question is the pondering of God created a universe with entropy, in “a wayward state” as the catechism eloquently puts it. So I will finally write this out in order to ponder such an event:
I’m reminded of St. Thomas’ bold statement in Contra Gentiles that evil comes, necessarily, from the good, because evil is accidental (in the sense of not being substantial or essential). Evil attempts to mimic the good by making it (evil) its own end (linked tightly to “polytheism”/idolatry). Thus, even while evil rejects God and is most unlike God, it cannot help but to mimic the good because there are no other metaphysical options! God was certainly genius/somewhat cunning in making all of creation that way

. In that sense, order arises out of chaos for the same reason evil cannot help but mimic the good. Now I understand that evil and chaos are certainly not strict synonyms (like the Greeks thought), but at least it will give some traction.
With that said, order still necessarily takes precedence over chaos insofar as existence is concerned because of that metaphysical dichotomy. Plus, there are some underlying issues concerning the objectivity of logic which I cannot seem to articulate right now. I understand there are still some holes in my explanation, but that’s the best I have right now!
