Those who, rejecting Scripture, imagine that they have some peculiar way of penetrating to God, are to be deemed not so much under the influence of error as madness.
– Book 1, Chap 9, Sec 1
For the Lord has so knit together the certainty of his word and his Spirit, that our minds are duly imbued with reverence for the word when the Spirit shining upon it enables us there to behold the face of God; and, on the other hand, we embrace the Spirit with no danger of delusion when we recognise him in his image, that is, in his word.
– Book 1, Chap 9, Sec 3
