Jon,
Logic = Consistency (according to my big bumper book of logic).
As such you can make a perfectly logical argument based on scripture, & perfectly logical ones based on empiricism. The split occurswhen you take a step back & try to determine the truth of the world around us & factor in all of the evidence. Scripture is more often than not guilty of being supported by no evidence at all (meaning no-one is compelled to accept), or contradicted by evidence (meaning no-one [i]should accept).
It is this latter logical fallacy that the religious are most guilty of.
There are 10 kinds of people in this world; those that understand binary, & those that don't
