T.F. Torrance is known to have criticized the traditional Calvinist doctrine of limited atonement (i.e. that Christ died in an efficacious way only for the elect) on the basis of its implicit Nestorianism, the early Christological heresy, condemned by the council of Ephesus in 431, that separated Christ’s divine nature from his human nature in such a way that he essentially came to be thought of as two distinct persons held together (in a single body, as it were) by a union of will. Now, at first blush, it may not be immediately apparent to the casual reader why Torrance would make this claim. What has Nestorianism (which relates to Christology) to do with limited atonement (which relates to soteriology)? A critic (though not an unappreciative one) of Torrance, Kevin Chiarot, argues that Torrance’s “continual application of Nestorianism to limited atonement seems overdone. The view is traditionally held by people who repudiate Nestorianism…[T]o accuse them of splitting incarnation and atonement, or the divine and human natures of Christ, is an exercise in question begging.” In response to critics like Chiarot, is anything to be said in Torrance’s defense?
Although I am sympathetic with those who struggle to see the connection that Torrance makes here (because it was not readily obvious to me at first), I am persuaded that he is fundamentally correct, and it is partly for this reason that I have personally advocated on this blog the need for traditional Calvinism to be reformed. To help explain why this is so, I would like to quote a section from Adam Neder’s excellent essay on Karl Barth’s view of the hypostatic union (i.e. the orthodox way of understanding Christ as having two natures united in one person). Neder writes:
When the Word became flesh, he did not cease to be God, but as the unfolding of election, and in accordance with the will of the Father, he became also a man. In an act of pure mercy and grace, God in his mode of being as the Son became flesh. But what, Barth asks, does it mean to say that the Word became flesh? It certainly cannot mean that he adopted into unity with himself one man among other human beings, nor can can it mean that he exists “in a duality” along side an individual man. For were that the case, the Son would not really have become flesh at all, and atonement would have been impossible, since that which occurs in the humanity of Jesus Christ is relevant for the rest of humanity only because Jesus Christ’s humanity is the humanity of God. Thus, Barth rejects adoptionism and Nestorianism because neither can support Jesus Christ’s work of reconciliation. In Barth’s parlance, the Nestorian Christ would simply be a man, not the man.
To underscore this point, he affirms the anhypostasis or impersonalitas of the human nature Christ. Jesus Christ exists as a man only as and because the Son of God exists as a man. The man Jesus “exists directly in and with the one God in the mode of existence of His eternal Son and Logos – not otherwise or apart from this mode.” Rather than uniting himself with a homo – an autonomously existing human being – “What God the Son assumed into unity with Himself and His divine being was and is – in a specific individual form elected and prepared for this purpose – not merely ‘a man’ but the humanum, the being and essence, the nature and kind, which is that of all men, which characterizes them as men, and distinguishes them from other creatures.” Barth defines this humanum (elsewhere he refers to it as humanitas) as the “concrete possibility of the existence of one man in a specific form.” Thus Jesus Christ is “a man” – a truly human being – who does not exist independently (anhypostasis), but exists only in the Word (enhypostasis).
Neder here employs some technical terms utilized by both Barth and Torrance to explicate the relationship between Christ’s divine and human natures. Basically, “enhypostasis” refers to the fact that when the Word became flesh, he did so by becoming a specific individual in a particular time and place: Jesus of Nazareth born of the virgin Mary. So far so good. But what Neder highlights is that an orthodox doctrine of the incarnation must go beyond a mere affirmation of enhypostasis. Why? It is because there is a serious error lurking in the background. On the basis of enhypostasis alone, would it not be conceivable that when Scripture affirms that the Word became flesh as Jesus of Nazareth, it simply means that the Word chose a man named Jesus of Nazareth who was already alive and then came to dwell in him? Indeed, the doctrine of enhypostasis alone does not guard against this possibility, which is nothing other than another heresy condemned by the early church as “adoptionism”. Even though Nestorianism was a bit more conservative in its approach (because it didn’t consider Jesus to have lived for some time prior to the Word coming to dwell in him), it essentially boiled down to the same error: it made it possible to think of Jesus of Nazareth in some measure as a distinct person with a theoretically independent existence apart from the divine Word. This is what Neder means when he says that, according to adoptionism and Nestorianism, Christ “exists ‘in a duality’ along side an individual man”.
Why is this so problematic? It is because, as Neder points out, it would mean that the Word did not actually himself become flesh. That is, the Word, the Son of God, would not have been himself the sole Subject of the incarnation, but would have shared that role with the man Jesus. In this view, the flesh that the Word assumed would not have become the flesh in which God was acting as the operative agent. But this would mean, then, that Paul was wrong in claiming that “in Christ God was reconciling the world to himself” (2 Cor. 5:19, emphasis mine). And if Paul was wrong, and it was not God himself who was in Christ reconciling the world to himself, then there would be no hope for salvation, because it is only God who can save!
For this reason, Barth (and Torrance, following the historic line of orthodox Christology) laid great emphasis on the fact that the man Jesus had no independent existence prior to or apart from the Word assuming flesh. This is the meaning of the word “anhypostasis”. Simply stated, anhypostasis means that there would have been no Jesus of Nazareth except that the Word had become flesh. It was the Word, and the Word alone, who was the Subject of the incarnation. This is, of course, not to take away anything from the full humanity of Jesus, which is what the concept of enhypostasis protects. Yet, without the Word’s assumption of human nature, there would have been no Jesus of Nazareth.
The upshot of affirming anhypostasis along with enhypostasis is that it means that Christ was not, as Neder explains, simply a man but also the man. In other words, since the Word did not, in the incarnation, assume an independent human person into union with himself, he must have assumed what Barth calls “humanum“, the “being and essence, the nature and kind, which is that of all men, which characterizes them as men, and distinguishes them from other creatures”. By assuming the nature that is common to and shared by all humanity, the Word entered into solidarity and union with all humanity. Yes, the Word became a man – Jesus of Nazareth (enhypostasis). But orthodox Christology demands that we also hold that the Word became the man, the new Adam, the one in whose humanity all people, without exception, are represented.
With these important concepts in place, we are in a position to see why Torrance can legitimately claim that limited atonement implies a Nestorian Christology. First he describes the fundamental problem with Nestorianism in the following way:
If Christ acted only in his human nature on the cross and God remained utterly apart and utterly transcendent, except that he agreed in will with Christ whom he sent to die, then all that Christ does is not necessarily what God does or accepts.
This is, in fact, the view of the atonement that logically follows from a Christ whose human flesh is not of God himself but of an independent human person, for if this is true, then we cannot affirm that it was God in Christ reconciling the world to himself on the cross because of the split between the divine and human natures of Christ. It is on this basis, and only on this basis, that we could then say that…
…the sacrifice of Christ may be accepted as satisfaction only for the number of the elect that God has previously chosen or determined. [For] if God himself came among us in Christ his beloved Son, and assumed upon himself our whole burden of guilt and judgment, then such an arbitrary view would be impossible. And we must hold the view that it is indeed God himself who bears our sins, God become man and taking man’s place, standing with humanity under the divine judgment, God the judge becoming himself the man judged and bearing his own judgment upon the sin of humanity, so that we cannot divorce the action of Christ from the action of God. The concept of a limited atonement thus rests upon a basic Nestorian heresy.
I hope the connection between limited atonement and Nestorianism is now more clear. Basically, if Christ died effectually only for a limited number of persons chosen from among all humanity in general, then the atonement must be understood only in terms of enhypostasis, that is, as the death of a Christ who was simply a man in union with the Son of God. If, on the other hand, we hold enhypostasis firmly together with anhypostasis (and we must do so in order to avoid the specter of Nestorianism), then we cannot say that Christ was simply a man but also man – the new Adam, the representative of all humanity – because only in this way can we maintain that Christ was truly the Word become flesh such that in Christ it was God reconciling the world to himself. But if this is true, and if the flesh that the Word assumed was not that of another distinct, independent person but that which came into being only in virtue of the incarnation, then his flesh was the humanum that is common to all humanity, and thus the reconciliation that he accomplished “in his body of flesh by his death” (Col. 1:22) must be said to avail for all. To say otherwise would be to drive a wedge between Christ’s divinity and humanity, and that, quite simply, is Nestorianism.
