Well I say a belief is rational if there's reason to believe that a belief is actually TRUE. And if there's reason to believe that a belief is actually TRUE then those reasons would IOW equate to evidence OF the truth of it. Because if there ISN'T evidence that it's actually true then you COULDN'T HAVE reason TO believe it's actually true because reason to believe it's actually true would IOW equate to evidence (and cancel out the faith, making the term 'rational faith' an oxymoron.).
