A “tight circle,” hopefully, is not to imply that circular reasoning is in play.I agree with your interpretation of Ratzinger. This is not the same as e_c’s original characterization, which was:
Indeed, it is exactly the reverse. E_C’s claim was that we can know God exists and is logical because the world is intelligible. Ratzinger is claiming that we can know the world is intelligible because God exists and is logical.
We could sew these two claims together into one tight circle, but the two claims are not the same.
The two claims may not be the same, but if the first implies the second and the second implies the first, independently of each other, that may be precisely what constitutes an irrefutable proof. They are inversely true of each other.
David Berlinski, roughly quoted, points out that Newton demonstrated that the planets are being attracted to the Sun by a force – not just any kind of force but an inverse square force. Then, if you make that assumption the result will be an orbit that conforms exactly to the orbit of the earth, or Mars or any of the planets – a conic section.
The inverse, then, is also true:
If the orbits conform to conic sections then the planets must be attracted to a central source by an inverse square law.

So, “exactly the reverse” and both true may constitute irrefutable proof.
