I would surmise there are beliefs held by scientists that would light up the superioposterior parietal cortex, which is associated with religious belief.
The point here is, if we’re going to define religious belief shouldn’t we look to neurobiology rather than language or semantics in order to find it?
Sure, and those beliefs could well be traditional Christianity, but any "lighting up" of any "neural areas" would be strictly non-scientific responses to a scientific discovery.
