Chapter 110 — That God cannot lose his own goodness
The foregoing clearly shows that God cannot in any way be deficient in goodness. For what is essential to a being cannot be lacking from it; for instance, ‘animal’ cannot be removed from ‘man.’ Neither is it possible for God not to be good. And to use an even more appropriate example: just as it is impossible for a man not to be a man, so it is impossible for God not to be perfectly good.
