In short, from the very first the Creator was both good and also just. And both His attributes advanced together. His goodness created, His justice arranged, the world; and in this process it even then decreed that the world should be formed of good materials, because it took counsel with goodness. The work of justice is apparent, in the separation which was pronounced between light and darkness, between day and night, between heaven and earth, between the water above and the water beneath, between the gathering together of the sea and the mass of the dry land, between the greater lights and the lesser, between the luminaries of the day and those of the night, between male and female, between the tree of knowledge of death and of life, between the world and paradise, between the aqueous and the earth-born animals. As goodness conceived all things, so did justice discriminate them. With the determination of the latter, everything was arranged and set in order. Every site and quality of the elements, their effect, motion, and state, the rise and setting of each, are the judicial determinations of the Creator. Do not suppose that His function as a judge must be defined as beginning when evil began, and so tarnish His justice with the cause of evil. By such considerations, then, do we show that this attribute advanced in company with goodness, the author of all things,—worthy of being herself, too, deemed innate and natural, and not as accidentally accruing to God, inasmuch as she was found to be in Him, her Lord, the arbiter of His works.

When evil afterwards broke out [due to man’s free choice of will], and the goodness of God began now to have an adversary to contend against, God’s justice also acquired another function, even that of directing His goodness according to men’s application for it. And this is the result: the divine goodness, being interrupted in that free course whereby God was spontaneously good, is now dispensed according to the deserts of every man; it is offered to the worthy, denied to the unworthy, taken away from the unthankful, and also avenged on all its enemies. Thus the entire office of justice in this respect becomes an agency for goodness: whatever it condemns by its judgment, whatever it chastises by its condemnation, whatever (to use your phrase) it ruthlessly pursues, it, in fact, benefits with good instead of injuring.
Indeed, the fear of judgment contributes to good, not to evil. For good, now contending with an enemy, was not strong enough to recommend itself by itself alone. At all events, if it could do so much , it could not keep its ground; for it had lost its impregnability through the foe, unless some power of fear supervened, such as might compel the very unwilling to seek after good, and take care of it. But who, when so many incentives to evil were assailing him, would desire that good, which he could despise with impunity? Who, again, would take care of what he could lose without danger? You read how broad is the road to evil, how thronged in comparison with the opposite: would not all glide down that road were there nothing in it to fear?
We dread the Creator’s tremendous threats, and yet scarcely turn away from evil. What, if He threatened not? Will you call this justice an evil, when it is all unfavourable to evil? Will you deny it to be a good, when it has its eye towards good? What sort of being ought you to wish God to be? Would it be right to prefer that He should be such, that sins might flourish under Him, and the devil make mock at Him?
Thus God is wholly good, because in all things He is on the side of good. In fact, He is omnipotent, because able both to help and to hurt. Merely to profit is a comparatively small matter, because it can do nothing else than a good turn. From such a conduct with what confidence can I hope for good, if this is its only ability? How can I follow after the reward of innocence, if I have no regard to the requital of wrong-doing? I must needs have my doubts whether he might not fail in recompensing one or other alternative, who was unequal in his resources to meet both. Thus far, then, justice is the very fulness of the Deity Himself.
