In fact, distinguishing knowledge from belief pretty much disqualifies it as a religion. Religions generally deny the value of knowledge, primarily by classifying knowledge as just another set of beliefs that's no better than anyone else's beliefs.
Actually, that's a bit of a misinterpretation of knowledge. And religion.
Assuming knowledge is a justified/rational/reliable/whatever true belief, there can be still religious knowledge. Now, most scientists wouldn't consider "mystical revelations" as a valid source of knowledge, being irrational/unreliable/whatever, but there's a lot of difference between a random belief and a supernatural-based belief, and religious scholars have made this distinction for centuries. There are lots of other non-empirical knowledge sources after all, math, logic, introspection, and so on, and faith could just be one of them.
What you're describing is a kind of relativism so extreme I don't think it has serious proponents. Not educated, anyway.
