6.4.6   I joyed also that the old Scriptures of the law and the Prophets were laid before me, not now to be perused with that eye to which before they seemed absurd, when I reviled Thy holy ones for so thinking, whereas indeed they thought not so: and with joy I heard Ambrose in his sermons to the people, oftentimes most diligently recommend this text for a rule, The letter killeth, but the Spirit giveth life; whilst he drew aside the mystic veil, laying open spiritually what, according to the letter, seemed to teach something unsound; teaching herein nothing that offended me, though he taught what I knew not as yet, whether it were true. For I kept my heart from assenting to any thing, fearing to fall headlong; but by hanging in suspense I was the worse killed. For I wished to be as assured of the things I saw not, as I was that seven and three are ten. For I was not so mad as to think that even this could not be comprehended; but I desired to have other things as clear as this, whether things corporeal, which were not present to my senses, or spiritual, whereof I knew not how to conceive, except corporeally. And by believing might I have been cured, that so the eyesight of my soul being cleared, might in some way be directed to Thy truth, which abideth always, and in no part faileth. But as it happens that one who has tried a bad physician, fears to trust himself with a good one, so was it with the health of my soul, which could not be healed but by believing, and lest it should believe falsehoods, refused to be cured; resisting Thy hands, Who hast prepared the medicines of faith, and hast applied them to the diseases of the whole world, and given unto them so great authority.
