I don't understand the mystical religious philosophy of snake-handlers either. I don't expect to. Nor do I expect to understand fuel injection systems in my car. Nor the Tax Code. But what I do expect in all these fields, is that those who do understand them (or those who refute them) can explain the basics in ordinary language. When they cannot, or when they fume and demand that I research this from the ground up, or insist that I categorically reject the whole thing, I lose faith. (By the way, an excellent example on this matter is the presentation in Moneyball. You may or may not agree with any of it, and the theory may or may not be dated or naive, but it is explained clearly and intelligently, and can be understood even by a casual sports fan.)
