Reading again through Saint Augustine’s Confessions”: Day 13 (No One is Better than God, the Incorruptible One)
“But then I would ask myself once more: ‘Who made me? Surely it was my God, who is not only good but Goodness itself. How, then, do I come to possess a will that can choose to do wrong and refuse to do good, thereby providing a just reason why I should be punished? Who put this will into me? Who sowed this seed of bitterness in me, when all that I am was made by my God, who is Sweetness itself? If it was the devil who put i there, who made the devil? if he was a good angel who became a devil because of his own wicked will, how did he come to possess the wicked will which made him a devil, when the Creator, who is entirely good, made him a good angel and nothing else?’
These thoughts wept me back again into the gulf where I was being stifled. But id id not sink as far as that hell of error where no one confesses to you his own guilt, choosing to believe that you suffer evil rather than that man does it.
Now that I had realized that what is incorruptible is better than that which is not, I took this as the basis for further research and acknowledge that, whatever your nature might be, you must be incorruptible. For no soul has ever been, or ever will be, able to conceive of anything better than you, who are the supreme, the perfect Good. And since, as I now believed, there could be no possible doubt that the incorruptible is better than the corruptible, it followed that you must be incorruptible; otherwise I should be able to think of something that was better than my God. So, once I had seen that the incorruptible is superior to the corruptible, I had to search for you in the light of this truth and make it the starting point of my inquiry into the origin of evil, that is, the origin of corruption, by which your substance cannot possibly be violated.
For there is no means whatsoever by which corruption can injure our God, whether by an act of will, by necessity, or by chance. This is because he is God and what he wills is good and he is himself that same Good; whereas to be corrupted is not good. And you are never compelled, my God, to do or suffer anything against your will, because your will is not greater than your power. It would be greater only if you were greater than yourself, for the will and power of God are God himself. Neither can anything unforeseen happen to you, because you know all things and nothing, whatever its nature, exists except by reason of the very fact that you know it. Need I say more to prove that the substance which is God cannot be corruptible since, if it were, it would not be God?”
