We swallowed the supernatural thing pretty easily in ST3.
Because it could be rationalized as an alien psionic ability rather than something divine or magical. If you call it "telepathy" or "psionics," give it a Latin or Greek name, then people perceive it as Science even if it's functionally indistinguishable from mysticism.
Good point. If the original idea for STV had been realized, a lot of us would be screaming about a respected science fiction series presenting the Judeo-Christian entities of God and Satan as real, living beings.
