Argument: Propositions 15 and 16 are contradictory. Therefore they cannot be true.
Response: The Fathers sometimes erred [labantur] in judgment, and sometimes speak correctly. Therefore we must not change them everywhere. Thus Bernard sometimes spoke very ineptly and improperly, as if he were a heretic. But when a serious matter was at stake, and he was speaking with God, then [as if] he were Peter or Paul himself. Therefore the Fathers are to be imitated where they have spoken and thought rightly, but where they have spoken or even thought improperly, they are to be tolerated and properly interpreted, as the papists do who force even [the Fathers] to come to their opinion.
