Now Aristotle says that the judgment which follows knowledge is in truth faith. Accordingly, faith is something superior to knowledge, and is its criterion. Conjecture, which is only a feeble supposition, counterfeits faith; as the flatterer counterfeits a friend, and the wolf the dog. And as the workman sees that by learning certain things he becomes an artificer, and the helmsman by being instructed in the art will be able to steer; he does not regard the mere wishing to become excellent and good enough, but he must learn it by the exercise of obedience. But to obey the Word, whom we call Instructor, is to believe Him, going against Him in nothing. For how can we take up a position of hostility to God? Knowledge, accordingly, is characterized by faith; and faith, by a kind of divine mutual and reciprocal correspondence, becomes characterized by knowledge.
