YOUCAT Question n. 51 - Part V. 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 385) God is infinitely good and all his works are good. Yet no one can escape the experience of suffering or the evils in nature which seem to be linked to the limitations proper to creatures: and above all to the question of moral evil. Where does evil come from? "I sought whence evil comes and there was no solution", said St. Augustine (St. Augustine, Conf. 7, 7, 11: PL 32, 739), and his own painful quest would only be resolved by his conversion to the living God. For "the mystery of lawlessness" is clarified only in the light of the "mystery of our religion" (2 Thess 2:7; 1 Tim 3:16). The revelation of divine love in Christ manifested at the same time the extent of evil and the superabundance of grace (Cf. Rom 5:20). We must therefore approach the question of the origin of evil by fixing the eyes of our faith on him who alone is its conqueror (Cf. Lk 11:21-22; Jn 16:11; 1 Jn 3:8).     

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 287) The truth about creation is so important for all of human life that God in his tenderness wanted to reveal to his People everything that is salutary to know on the subject. Beyond the natural knowledge that every man can have of the Creator (Cf. Acts 17:24-29; Rom 1:19-20), God progressively revealed to Israel the mystery of creation. He who chose the patriarchs, who brought Israel out of Egypt, and who by choosing Israel created and formed it, this same God reveals himself as the One to whom belong all the peoples of the earth, and the whole earth itself; he is the One who alone "made heaven and earth" (Cf. Isa 43:1; Pss 115:15; 124:8; 134:3).      

(The next question is: What is heaven?)
