Now all men, having the same judgment, some, following the Word speaking, frame for themselves proofs; while others, giving themselves up to pleasures, wrest Scripture, in accordance with their lusts. And the lover of truth, as I think, needs force of soul. For those who make the greatest attempts must fail in things of the highest importance; unless, receiving from the truth itself the rule of the truth, they cleave to the truth. But such people, in consequence of falling away from the right path, err in most individual points; as you might expect from not having the faculty for judging of what is true and false, strictly trained to select what is essential. For if they had, they would have obeyed the Scriptures.
