This is what you should believe
We won't tell you why you should believe it
but if you don't ask any questions and believe it anyway, we promise a super-duper reward...


This is essentially the essence of "faith" that bothers me. If I used such logic to make any other claim people would say to me "what, do you think I'm stupid?", but call it "faith" and you can't touch it. The whole concept is a means of making sure people don't ask questions, and I would think any true claim could stand up against any and all questions.
