1) Prime Mover? Thomas Aquinas today? Ok, I will bite the bait. No the cause of any affect is the interaction between space-time and quantum fields (around 150 as today), and the transmissions of forces to make a force through bosons. (More or less).
2) There can be a first cause alone to predetermine everything at the end. Even when a system is perfectly known an described by a set of equations, the predictions at long time cannot be made due to deterministic chaos. Not mentioning natural limits.
3) Or simple a consequence of the rules existing.
4) Slow here, cowboy. The mistake of theologians and philosopher, running to their conclusions.
"This materialistic potency will not result in a rational, secular order, but a rational, secular chaos" [And the point is ...? You are supposing innate moral values to order and chaos. But it doesn't work like that. Life is a complex system in the verge of both. Do you like a ordered system? Try a mineral crystal. Dead.
Even more, chaos can be the result of a highly complex order. We are long beyond the conception of the world like a clockwork or even needing one clock maker]
since it only possesses its first actuality--existence--and not its second actuality-- [Nope; not second guessing or occult variables. The Bell's Theorem is clear, uncertainty prevail].
a form actuated by striving towards God [That's teleological, not a logical consequence. It's the expression of a desire, not a conclusion. Even the repacked "Omega" point from some transhumanists. They are simply relabeling in a secular way Christian theology.]
, the final cause of all things, [Not even close. Besides for a innate truth, religion can be funny contentious, which supreme god? Why not a pantheon? Or a philosophical principle? Ah, the constraints of Abrahamic Tree of religions]
as secularism ipso facto is a renunciation of the Divine [No it is a separation. Even in the Bible by Jesus, Matthew 22:21 Jesus said "Render to Caesar the things that are Caesar's; and to God the things that are God's." By the way you are mistaking secularism (the separation of religion influence on civil society with atheism, with no consideration to agnosticism).
Unfortunately quite common.
as the proper end of existence. [Something that it is more than vaporous that one can be for sure. (Simulation hypothesis and Bolztmann Brains)]
Well played. [We have barely begun]
