“You know well enough that it is the saints who will pass judgement on the world; and if a world is to abide your judgement, are you unfit to take cognizance of trifling matters? You have been told that we shall sit in judgement on angels; how much more, then, over the things of common life?” (1 Corinthians 6:2-3)
