You've got yourself a problem there, don't you, Jackal-Head-Guy? We've got pretty durn good evidence that many parts, not just "any part," of the Bible are false, so you inerrantists are rather in a bind, eh?
"The wretched world lies now under the tyranny of foolishness; things are believed by Christians of such absurdity as no one ever could aforetime induce the heathen to believe." - Agobard of Lyons,
ca. 830 AD
