YOUCAT Question n. 51 - Part II. If God is all-knowing and all-powerful, why does he not prevent evil?

(Youcat answer - repeated) “God allows evil only so as to make something better result from it” (St. Thomas Aquinas).        

A deepening through CCC

(CCC 40) Since our knowledge of God is limited, our language about him is equally so. We can name God only by taking creatures as our starting point, and in accordance with our limited human ways of knowing and thinking. (CCC 310) But why did God not create a world so perfect that no evil could exist in it? With infinite power God could always create something better (Cf. St. Thomas Aquinas, STh I, 25, 6). But with infinite wisdom and goodness God freely willed to create a world "in a state of journeying" towards its ultimate perfection. In God's plan this process of becoming involves the appearance of certain beings and the disappearance of others, the existence of the more perfect alongside the less perfect, both constructive and destructive forces of nature. With physical good there exists also physical evil as long as creation has not reached perfection (Cf. St. Thomas Aquinas, SCG III, 71).   

Reflecting and meditating 

(Youcat comment) Evil in the world is an obscure and painful mystery. Even the Crucified asked his Father, “My God, why have you forsaken me?” (Mt 27:46). Much about it is incomprehensible. One thing, though, we know for sure: God is 100 percent good. He can never be the originator of something evil. God created the world to be good, but it is not yet complete. In violent upheavals and painful processes it is being shaped and moved toward its final perfection. That may be a better way to classify what the Church calls physical evil, for example, a birth defect, or a natural catastrophe. Moral evils, in contrast, come about through the misuse of freedom in the world. “Hell on earth”—child soldiers, suicide bombings, concentration camps—is usually man-made. The decisive question is therefore not, “How can anyone believe in a good God when there is so much evil?” but rather, “How could a person with a heart and understanding endure life in this world if God did not exist?” Christ’s death and Resurrection show us that evil did not have the first word, nor does it have the last. God made absolute good result from the worst evil. We believe that in the Last Judgment God will put an end to all injustice. In the life of the world to come, evil no longer has any place and suffering ends.    

(CCC Comment)

(CCC 311) Angels and men, as intelligent and free creatures, have to journey toward their ultimate destinies by their free choice and preferential love. They can therefore go astray. Indeed, they have sinned. Thus has moral evil, incommensurably more harmful than physical evil, entered the world. God is in no way, directly or indirectly, the cause of moral evil (Cf. St. Augustine, De libero arbitrio 1, 1, 2: PL 32, 1223; St. Thomas Aquinas, STh I-II, 79, 1). He permits it, however, because he respects the freedom of his creatures and, mysteriously, knows how to derive good from it: For almighty God…, because he is supremely good, would never allow any evil whatsoever to exist in his works if he were not so all-powerful and good as to cause good to emerge from evil itself (St. Augustine, Enchiridion 3, 11: PL 40, 236).
