JP takes simple ideas and helps me to understand them properly, instead of vaguely.

He takes a simple idea (which may or may not be true) and makes it sound as if he has come up with something profound from it. In the case of his Bible story, it is a castle built on sand. Almost nothing of what he says is true except that later (mostly Christian) writers were influenced by the Bible. Well, no shit, Sherlock! But they were also influenced by other traditions, for example, Norse mythology, which have nothing to do with the Bible. In short, he says something that has a grain of truth, blows it up way beyond its significance and presents it as a cosmic revelation. The mark of a charlatan.

Also, the bible was the first book mass-produced by the printing press. Which is no small thing.

True, but not what he said and actually irrelevant to the argument.
