Anselm’s Cur Deus Homo, part 7.
After an interlude in which Boso mounts an effective criticism of the Ransom Theory of Atonement (ch. 6-7), when Anselm presses him to state what it is precisely that people find in the doctrine of the Incarnation to be contrary to reason, Boso reiterates the earlier aesthetic objection with now an additional, economic twist: “that the Most High descends to such lowly things, that the Almighty does something so laboriously” (ch. 8). This time, surprisingly, instead of countering with an argument for the fittingness of God doing such things, Anselm responds by conceding the objection, all the while denying that it was the divine nature rather than the human nature of Christ that endured such labor and lowliness. According to Anselm, “For without doubt we maintain that the divine nature is impassible—that it cannot at all be brought down from its exaltation and cannot labor in what it wills to do… Therefore, when we state that God undergoes some lowliness or weakness, we understand this to be in accordance with the weakness of the human substance which He assumed, not in accordance with the sublimity of His impassible nature.” Anselm reprises here his position on divine impassibility from Proslogion 8, where he had argued that, because God has no passions and hence can have no “heart sorrowful out of compassion for the wretched—the very thing which being merciful is,” it follows that while God may be merciful “from our point of view” and in our experience of his “effects,” he is not merciful in himself or in his own “experience.” Yet Anselm’s argument may be set in contrast with his own discussion of divine sense perception only two chapters earlier in the Proslogion. Although God does not have a body, Anselm reasons, because sense perception is ordered towards knowledge, and “whatever in some ways knows is not unsuitably (non inconvenienter) said in some way to perceive,” and because God knows all things, God may be said not to lack sense perception so much as to be “supremely able to perceive” (Pros. 6). If so, then by the same reasoning we might conclude, contrary to Anselm, that insofar as creaturely passions such as mercy and vicarious suffering are ordered towards love, and God is love, neither should it “unsuitably be said” that God is merciful or that, in the Incarnation, there is a sense in which even the divine nature itself “undergoes some lowliness or weakness.” If it involved a created perfection, after all, for Christ’s human nature to experience these things, and if all created perfections preexist in the divine being (as Anselm argues, for example, in Monologion 9), then at some level we must affirm that all the goodness and sacrifice involved in the course of Christ’s human experience preexisted—albeit in an eminent and impassible, or as we prefer to say, superpassible fashion—there as well. On Anselm’s own theological metaphysics, in sum, it is what the divine nature of Christ is that is the foundation of every creaturely possibility, including the possibilities of Christ’s human nature.
