God is perfectly good in and of himself. How then is it compatible with God’s perfect goodness to create a universe with a significant probability of eternal evil? The eternal evil I speak of is that of Satan, demons, and damned humans.
Think of it the comparison between these two worlds:
- Only God exists. This world has infinite goodness and no possibility for evil.
- God and free creatures exist. This world has infinite goodness but also the possibility for eternal damnation and evil.
No more goodness can be attained by creating. Only the possibility of evil is added.
I think it would help to think of God’s goodness in
qualitative more than quantitative terms, ie as a qualitative infinite and not an quantitative infinite. This way you understand that when we speak of God’s goodness,
we do not mean that God has an infinite quantity or amount of goodness. Rather we mean that God is qualitatively good. He is morally perfect, without moral defect, and is indeed, the paradigm of moral goodness. To speak of God as infinite Goodness is simply to say that he in essence morally perfect, without moral defect, and the paradigm of moral goodness. And so when we call God infinite goodness, we mean infinite in a qualitative sense.
So it is not a question of God having goodness added to Him by creation. He was already morally perfect. Rather in creation, he creates other things that are good as well, but this does not mean that he was not already morally perfect.
And he creates things with the possibility of evil, of course, because creatures freely united to him enjoying heaven forever is worth the risk of evil. And for this, he must create free will. So many philosophers would say that the creation of creatures with free will is a morally sufficient reason for God to allow the possibility of evil.
For example, let’s say God creates a person Bill, and leaves it up to Bill whether or not he will follow God. And let’s say that Bill, if it is left up to him, would not follow God. Can God do anything to make Bill follow him? Not if he is to respect Bill’s free will.
And this freedom of course is why the doctrine of hell is so necessary. Some people may eternally will to reject God. He allows that choice because He allows free will. To ask hell not to exist is to ask that people not be free.
Hell, as Fulton Sheen says, is the final guarantee of human freedom. The guarantee that a damned soul can forever raised his clenched fist at God and say “non serviat.” (I will not serve). Like Milton’s Satan who decided it was “better to reign in hell than serve in heaven.”
