I think you'll find a lot of Christians saying that the Trinity is a consistent explanation of why many phenomena occur, and so that's equivalent to saying that we know Christ exists.

Scientists can apply science to disprove God.
Christians can apply doctrine to disprove science. (Yes they can; some specific aspects of it, anyway.)

Once you get into such details, you've already chosen a side, and that choice dictates your entire paradigm.

But if you step back and think OUTSIDE that choice (objectively, if such a stance is really possible), there's this amazing parallel. And I think that recognizing that parallel can lead to a greater understanding of the "other side."

Yes, I know, science and math and empirical evidence are, to us non-religious types, "PROOF" of our beliefs. Belief becomes "fact." ... But it's the same thing for religion. To the faithful, doctrine is "PROOF" -- it's fact.

From either side, the other side looks absurd and misguided. But the absurdity, running both ways, is parallel. I think that's amazing.
