From Confessions XII.25:
But I will not tolerate their contention that Moses meant, not what I say he meant, but only what they say. It appals me, because even if their explanation is the right one, the arbitrary assurance with which they insist upon it springs from presumption, not from knowledge. It is the child of arrogance, not of true vision.
In other words: “You’re not wrong, you’re just an asshole.”
