Neither therefore can the term "physical causation" or any other physical terms, e.g. physical laws, operate as restrictions on God.
God is the only possible candidate for the uncaused cause (first cause) of causation.
All physical cosmologies rely on space/time for physical causation (e.g. multi-verse, multi-world, cyclic, ekpyrotic, imaginary time.) They cannot have an infinite past (plentitude argument, everything that can happen did) because there was a beginning of real space and real time. All they do is move the goal post to prior space/time which also had a beginning, i.e. a finite chain of prior physical causation.
Truly, the only closed cosmology known to me is Max Tegmark's Level IV Parallel universe which is closed precisely because it is radical Platonism. In his view, the perceptible physical world (the frog view) is a manifestation of the real mathematical structures which actually exist outside of space and time.
The Platonic paradigm raises the question of why the universe is the way it is. To an Aristotelian, this is a meaningless question: The universe just is. But a Platonist cannot help but wonder why it could not have been different. If the universe is inherently mathematical, then why was only one of the many mathematical structures singled out to describe a universe? A fundamental asymmetry appears to be built into the very heart of reality.

But the frog cannot discern this because he relies first on his sensory perception for knowledge. He is a natural man. To him, the particle is in an orbit, the wave is continuous. He cannot perceive by sensory perception alone the beginning and end of it.
The bird whose perspective is Platonist - the "beyond" - discerns this. Sensory perception is not his most certain source of knowledge. Reasoning to the Platonist would trump sensory perception.
More importantly, the Christian discerns the "beyond" directly, Spiritually - even if he does not have the terms of mathematics, physics and philosophy to describe it to others.
Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know [them], because they are spiritually discerned. I Corinthians 2:11-14
To God be the glory!
Just because aspects of God are outside of time and space doesn't mean that others are not in time and space. Certainly the Son and the Holy Ghost have physical and temporal qualities, but I digress. I agree that your concept of God is eternal and uncaused and outside of time and space. This is a theological statement and a belief based on faith. It cannot therefore be argued.
Philosophically and scientifically, however, it is encumbent upon you to show why one class of object, let's call it the "supernatural" can exist outside of space-time and cause events inside of space-time, but other classes of objects may not.
Tegmark and Plato may be right or they may be wrong about mathematical constructs existing outside of space-time. Clearly this is another form of the koan: "tree falling in forest with no one to hear".
It is also the core of my cosmology. Interestingly, in "Timothy" you birdies mention Dawkins repeatedly, but I have yet to see references to the memes that he invented. (I'm only half way through (I read Gatsby in 2 hours which says something about Timothy)).
There is no doubt thgat Bethoven's fifth exists in space-time. It was created in space-time by a creature of space-time. And yet it doesn't exist anymore than the Pythagorean theorem absent some medium. It moved from a mind to written music to another mind to a wax disc to vinyl to tape to cd and it will exist as long as some form of memory exists.
If you listen carefully, you will learn that you too are just a signal in the fabric of space-time. All that exists is space-time and unique peices of information contained in discrete wave packets of space-time. That includes you and me and God and Satan and ducks and pencils and all other nouns and pronouns. I forget the word used for a discrete wave packet that behaves like a wave. It was discovered in Edinburgh in the 19th century near Heriot Watt University.
Dawkins didn't get it with his memes. He thought they were physical structures in brains, but they are your theoretical information outside (but really inside) of space-time.
