I've merely quoted an often-quoted fact from logic.
So you do take some things on faith.
I'm only kidding, Ben. But it does remind me of something I heard long ago. I was watching Asimov being interviewed on television and, although I can't quote him exactly now, he said something along the lines of "Science is of higher moral ground than religion. If science discovers something that does not agree with its most valued theories, the theories are thrown out - or modified. When religion discovers something inconsistent with its dogma, the evidence is destroyed." So, you'd be right, imho, to be more willing to accept at face value a "widely held scientific/mathematical truth" than any religious truth.
IMO, there is damned little sacred about organized religion. The religion I spoke of in this thread is a personal religion, which can neither be taught, explained, nor discussed. True religion comes from within. Even discussing religion is a fool's errand. There's an old Taoist saying, "Those who know do not speak. Those who speak freely do not know." That'd apply to darned near every "professional" religious zealot (preachers,priests,mullahs,rabbis,etc.) I know.
