Can't mean what it says. Doctrine is not in the bible! Doctrine is only man's. That would be judging people by their doctrine. Nahh.

Paul, who cares about your doctrine. Doctrines are of no concern to God .

If people don't hear the apostles, they're not of God? Nah. That's judging people by their Doctrines. God wouldn't do that. Wrong again, John.
