In brief, they're mathematical proofs that certain things are unknowable. Mathematics rarely gets so close to theology. And religion is rarely so certain.
Oh, so before you learned about the theorems, you thought you could know anything, and the theorems set you right on that point? And somehow that was a theological or transcendental experience?
There's a big difference in the emotional experience of thinking you know something, and actually having proof of it. I think most theists would be similarly amazed by an encounter with a deity.
