Faith is either NO reason to believe, or a BAD reason to believe. And if you have reasons TO 'have faith' then if they're at all valid reasons, if they're NOT BAD reasons - then they'd have to equate to evidence of the truth of the belief; if they didn't they'd be BAD reasons (or 'irrational' or 'invalid'). So rational reasons to have faith BECAUSE they'd equate to evidence IF they're INDEED rational - that would cancel out the faith. Because you cannot have faith with evidence. So the term 'rational faith' is an oxymoron.
