Faith is the Basis of Human Life; Man Cannot Discover that Truth Which Holy Scripture Has Disclosed
7 From this, however, being led to prefer the Catholic doctrine, I felt that it was with more moderation and honesty that it commanded things to be believed that were not demonstrated (whether it was that they could be demonstrated, but not to any one, or could not be demonstrated at all), than was the method of the Manichæans, where our credulity was mocked by audacious promise of knowledge, and then so many most fabulous and absurd things were forced upon belief because they were not capable of demonstration. After that, O Lord, You, little by little, with most gentle and most merciful hand, drawing and calming my heart, persuaded taking into consideration what a multiplicity of things which I had never seen, nor was present when they were enacted, like so many of the things in secular history, and so many accounts of places and cities which I had not seen; so many of friends, so many of physicians, so many now of these men, now of those, which unless we should believe, we should do nothing at all in this life; lastly, with how unalterable an assurance I believed of what parents I was born, which it would have been impossible for me to know otherwise than by hearsay—taking into consideration all this, You persuade me that not they who believed Your books (which, with so great authority, You have established among nearly all nations), but those who believed them not were to be blamed; and that those men were not to be listened unto who should say to me, “How do you know that those Scriptures were imparted unto mankind by the Spirit of the one true and most true God?” For it was the same thing that was most of all to be believed, since no wranglings of blasphemous questions, whereof I had read so many among the self-contradicting philosophers, could once wring the belief from me that You are—whatsoever You were, though what I knew not—or that the government of human affairs belongs to You.
8. Thus much I believed, at one time more strongly than another, yet did I ever believe both that You were, and had a care of us, although I was ignorant both what was to be thought of Your substance, and what way led, or led back to You. Seeing, then, that we were too weak by unaided reason to find out the truth, and for this cause needed the authority of the holy writings, I had now begun to believe that You would by no means have given such excellency of authority to those Scriptures throughout all lands, had it not been Your will thereby to be believed in, and thereby sought. For now those things which heretofore appeared incongruous to me in the Scripture, and used to offend me, having heard various of them expounded reasonably, I referred to the depth of the mysteries, and its authority seemed to me all the more venerable and worthy of religious belief, in that, while it was visible for all to read it, it reserved the majesty of its secret within its profound significance, stooping to all in the great plainness of its language and lowliness of its style, yet exercising the application of such as are not light of heart; that it might receive all into its common bosom, and through narrow passages waft over some few towards You, yet many more than if it did not stand upon such a height of authority, nor allured multitudes within its bosom by its holy humility. These things I meditated upon, and You were with me; I sighed, and You heard me; I vacillated, and You guided me; I roamed through the broad way of the world, and You did not desert me.
