302 Creation has its own goodness and proper perfection, but it did not spring forth complete from the hands of the Creator. The universe was created “in a state of journeying” (
in statu viae ) toward an ultimate perfection yet to be attained, to which God has destined it. We call “divine providence” the dispositions by which God guides his creation toward this perfection:
By his providence God protects and governs all things which he has made, “reaching mightily from one end of the earth to the other, and ordering all things well”. For “all are open and laid bare to his eyes”, even those things which are yet to come into existence through the free action of creatures.161
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.174 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.175
