The alternative tradition, which predates Augustine, is that God annihilates evil by restoring the universe to himself, thereby healing it. The restoration of creation is the destruction of evil, for evil has no substantial reality.
Evil must necessarily be eliminated, absolutely and in every respect, once and for all, from all that is, and since in fact it is not […], neither will it have to exist at all. For, as evil does not exist in its nature outside will, once each will has come to be in God, evil will be reduced to complete disappearance, because no receptacle will be left for it. . . . [I]t seems to me that Scripture teaches the complete disappearance of evil. For, if in all beings there will be God, clearly in them there will be no evil.1
Gregory of Nyssa, De an. 101, 104
And God will not obliterate the good substantial beings he has made. As Al Wolters one said: “God does not create trash, and he does not trash what he creates.” Commenting on Psalm 59:6, 14, Gregory writes, “There will be no destruction of humans, that the work of God may not be emptied by annihilation. Instead of human creatures, what will be destroyed and reduced to non-being will be sin.” In a similar vein, Athanasius writes: “Christ, because he is good and loves humanity, came to bring fire onto earth. . . . He wanted the repentance and conversion of the human being rather than its death. In this way, evilness, all of it, will be burnt away from all human beings” (Ep. 3.4.8). Exitus et reditus.
I ought to flag up at this point that all analogies have limitations, and the problem in this context with the hospital analogy is that it fails to do justice to the critical notions of human responsibility for evil and divine judgment on human evil. So I am not trying to be comprehensive here, to say everything that needs to be said about God’s response to human evil, but merely to indicate the manner in which evil is finally annihilated: namely, by eradicating it from humans, rather than by eradicating the humans themselves. The idea of healing communicates that well.
This was the theological framework within which eschatological punishment was interpreted by more than a few of the Fathers. Consequently, hell was understood to be a means to a salvific end, not the everlasting fate of anyone. Such Fathers had no qualms about affirming the biblical teachings on final punishment, and did not shrink from the biblical imagery and language, but such were understood in this wider theological framework. The flames of hell were understood as flames of justice, of course, but simultaneously as flames of divine love. Hell was God’s burning love. St Isaac of Nineveh puts this rather well:
If we said or thought that what concerns Gehenna is not in fact full of love and mixed with compassion, this would be an opinion full of blasphemy and abuse against God our Lord. . . . Among all his deeds, there is none that is not entirely dictated by mercy, love, and compassion. This is the beginning and the end of God’s attitude toward us.2.
St Isaac of Nineveh, Second Part, 39.22
Or, as someone else put it, LOVE WINS.
1. “For it is clear that it will be the case that God is ‘in all’ only when in the beings it will be impossible to detect any evil” (Gregory of Nyssa, In Illud, 17 Downing).
2. “I also maintain that those who are punished in Gehenna are scourged by the scourge of love. For what is so bitter and vehement as the punishment of love? I mean that those who have become conscious that they have sinned against love suffer greater torment from this than from any fear of punishment. For the sorrow caused in the heart by sin against love is sharper than any torment that can be. It would be improper for a man to think that sinners in Gehenna are deprived of the love of God. Love is the offspring of knowledge of the truth which, as is commonly confessed, is given to all. The power of love works in two ways: it torments those who have played the fool, even as happens here when a friend suffers from a friend; but it becomes a source of joy for those who have observed its duties. Thus I say that this is the torment of Gehenna: bitter regret. But love inebriates the souls of the sons of Heaven by its delectability.” (Isaac, I.28, p. 266)
