What I am saying is that we are at some point probably going to prove pretty much all of the this-worldy, pragmatic (moral, sociological, psychological etc.) aspect of Catholicism correct by something like evolutionary psychology.Everything. We see through a glass darkly. When you have removed everything else, the only thing left is faith.
And I am saying that while it will dramatically increase our respect for religion, this will also be probably a huge blow to theism. I don’t want that to happen, but I think it will. Because eliminating God from the gaps of natural science does not hurt faith much. But eliminating God from the gaps of the humanities and yes, religion itself?
OK it is also possible that all we prove is that God was actually giving people good advice and it does not disprove Him the slightest. But look. It would still disprove most everything about people imagine and think about God. Because pretty much all of that would be programming – making people grasp, adopt and stick to good pragmatic humanities ideas.
So it would mean at least a very mysterious God we know nothing about, not the one we feel is familiar.
...But if you strip away everything, really everything that is potentially instrumental, you have a God you really know nothing about. What does belief, faith mean then?
All we about God is what he has revealed. Even then, what he has revealed is rather limited. The Trinity doesn't limit God. God is not 3 in 1, he's infinity in one. He's only revealed 3. People struggle with the divinity of Jesus and that's only 2 in 1. If you can understand 3 in 1, you have the concept down and that's the important thing. If you tried showing 4, 5, 6, 10 in 1 then you're going to end up doing string theory. Reason is a hindrance in the modern age because we rely on it for everything. Sometimes people suffer a loss of faith, but I'd wager most people reason their way out of faith these days.
The faithful already believe all of the Bible's instructions on human nature are true. Science confirming it would be the culmination of several centuries of Doubting Thomases running experiments. Theism would expand because it would become a much larger part of what remains of religion. Similar to what Spotted Toad predicted for a society run by algorithms. As more and more of what can be controlled is controlled, then by exclusion the "surprises" will increasingly be random. Bad luck will become a far more common explanation for accidents in a "perfect" world. Religion will become more mysterious, not less, as the non-mysterious parts of the Bible are proven true.
