That's interesting because it seems to me your description of Mormon practice is consistent with what I'm saying.

You point to an “internal resonance with the community's beliefs.” Isn't that just tribal pride in being part of the community? The religious belief itself would be an expression of that pride, but to belong in the first place you must prove your faith by faking it until you make it. You’d proclaim superficially that you believe X and Y, and you’d perform the various rituals, but the overriding purpose, I'm saying, is the social not the cognitive one. The point isn't to acquire theological knowledge (since God would be beyond our comprehension); rather, the point is to pay your dues to be part of a community. And I think you end up saying the same thing here.

Of course, this will be unconscious and rationalized in the Age of Reason in which religion competes with science and philosophy. The religious person will attest that she does believe certain theological propositions are true. But who says knowing yourself is easy?
