Cur Deus Homo/Book First/Chapter 4

CHAPTER IV
How these things appear not decisive to infidels, and merely like so many pictures.

Boso. These things must be admitted to be beautiful, and like so many pictures; but, if they have no solid foundation, they do not appear sufficient to infidels, as reasons why we ought to believe that God wished to suffer the things which we speak of. For when one wishes to make a picture, he selects something substantial to paint it upon, so that his picture may remain. For no one paints in water or in air, because no traces of the picture remain in them. Wherefore, when we hold up to infidels these harmonious proportions which you speak of as so many pictures of the real thing, since they do not think this belief of ours a reality, but only a fiction, they consider us, as it were, to be painting upon a cloud. Therefore the rational existence of the truth first be shown, I mean, the necessity, which proves that God ought to or could have condescended to those things which we affirm. Afterwards, to make the body of the truth, so to speak, shine forth more clearly, these harmonious proportions, like pictures of the body, must be described.

Anselm. Does not the reason why God ought to do the things we speak of seem absolute enough when we consider that the human race, that work of his so very precious, was wholly ruined, and that it was not seemly that the purpose which God had made concerning man should fall to the ground; and, moreover, that this purpose could not be carried into effect unless the human race were delivered by their Creator himself?
