God. There's an interesting character. Personally, I don't believe that God wrote anything. He didn't scribe the 10 Commandments, he had nothing to with the Bible (except inasmuch as the Bible represents the attempts of ancient men to explain things, including God and their own natures). Like the Deists of the 18th century, I believe God created things, then let them unfold as they will. While I believe that God exists, I think the "God of Abraham" is almost entirely an invention, created in the image of the Sons of Abraham. God was a convenient scapegoat for the atrocities of man, especially the atrocities of the authors of the Bible (better to blame an elusive all-powerful deity than to take personal responsibility for evil of genocide). On the positive side, God was also a wonderful tool for rallying the masses behind a cause, or for keeping the masses under control. Hence, the biblical (and every other kind) God eventually took shape.
God didn't write the 10 Commandments, men did. God didn't write the Bible, men did. God didn't order the genocide of the enemies of Israel, men did. God didn't order dozens of children murdered for laughing at a bald man, men did. God wasn't responsible for the defeat of Hitler, men were. God wasn't responsible for the fall of the Berlin wall, men were. God didn't tell GWB to go to war in Iraq, men did. God didn't send the tsunami to punish the heathens, or Katrina to punish the wicked city of New Orleans, those were just normal (though catastrophic) acts of nature.
One of the funniest attributions I've seen people give to God was when some of the right-wing nutjobs like Pat Robertson, Jerry Falwell, et al, claimed that Katrina was sent to punish the wickedness of New Orleaneans. God must have lousy aim, because he missed Bourbon Street altogether!
