I think y'all are way off on that. It isn't about the show's God, Bible God, or any of that shit. It IS about how those compelled by The Voice interpret what they are told to do.
Like the guy who cut is heart out as he took it literally. When I meant the "nature" of the order he was giving its more like, what does Quincannon consider to be God? How is he serving it by killing off people and such?
Seems more like he considers himself, money, or power god or something like that. Also he's just generally creepy as fuck as you see him listening to animals being slaughtered from his office all day.
