For Thomas Torrance the atonement is the contradiction of sin by which Godself inserts himself into the brokenness and fallen-ness of our humanity, through the humanity of Christ, and by so doing vanquishes sin—its death and destruction—by his very own and sui generis being as God and man in Christ. We left off in the last post referring to sin in the theology of Torrance, let me briefly touch upon that further here.
For Torrance sin isn’t simply a transactional or legal situation it is something that touches the deepest reaches of what it means to be a human being; it sub-humanizes people because it disintegrates the koinonial bond that was originally inherent to what it meant for a human to be a human created in the image of God as an image of the image who is Christ (cf. Col. 1.15). This is why for Torrance, and us Evangelical Calvinists following, what was required in the atonement was that our very beings as human beings be recreated in the human being that Jesus assumed enhypostatically as the man from Nazareth. You won’t find this type of penetrative consideration in the forensic framing of atonement that you find in Federal or Covenantal theology; or for that matter, as a subset, what you find in more basic accounts of Reformed theology as we see typified in what is popularly called Five-Point-Calvinism.
Here is an example of how Torrance thinks about the depth dimension of salvation/atonement:
On the cross, the oneness of God and man in Christ is inserted into the midst of our being, into the midst of our sinful existence and history, into the midst of our guilt and death. The inserting of the oneness of God and man into the deepest depths of human existence in its awful estrangement from God, and the enactment of it in the midst of its sin and in spite of all that sin can do against it, is atonement. In a profound sense, atonement is the insertion of the union into the very being of our alienated and fallen humanity. That insertion of oneness by atonement results in koinōnia, in the church as the communion in which Christ dwells, and in which we are made partakers of the divine nature. The koinōnia thus created by the atonement and resurrection of Christ is fully actualised in our midst by the outpouring of the Holy Spirit, and is maintained by the power of the Spirit as the church continues in the fellowship of word and sacrament….
As we have been emphasizing, for Torrance, and then us Evangelical Calvinists in his wake, salvation is an ontological occurrence; of necessity. The Apostle Paul is quite clear about the depth and reach of sin’s impact, which is why he emphasizes creational and new creational themes so frequently (cf. II Cor. 5:17; Rom. 8:18ff; Col. 1:15ff; etc.). Torrance along with a part of the Christian tradition simply notes this reality in the Apostolic deposit found in the New Testament and seeks to develop the inner logic being presupposed upon by Apostles like Paul et al.
Here is one more example of how Torrance thinks salvation. Here we have an example of what Torrance calls the ‘ontological theory of the atonement,’ it is in line with what we just read from him previously:
It is above all in the Cross of Christ that evil is unmasked for what it actually is, in its inconceivable wickedness and malevolence, in its sheer contradiction of the love of God incarnate in Jesus Christ, in its undiluted enmity to God himself—not to mention the way in which it operates under the cover of the right and the good and the lawful. That the infinite God should take the way of the Cross to save mankind from the pit of evil which has engulfed it and deceived it, is the measure of the evil of evil: its depth is revealed to be ‘absymal’ (literally, ‘without bottom’). However, it is only from the vantage point of God’s victory over evil in the resurrection of Christ, from the bridge which in him God has overthrown across the chasm of evil that has opened up in our violence and death and guilt, that we may look into the full horror of it all and not be destroyed in the withering of our souls through misanthropy, pessimism, and despair. What hope could there ever be for a humanity that crucifies the incarnate love of God and sets itself implacably against the order of divine love even at the point of its atoning and healing operation? But the resurrection tells us that evil, even this abysmal evil, does not and cannot have the last word, for that belongs to the love of God which has negated evil once and for all and which through the Cross and resurrection is able to make all things work together for good, so that nothing in the end will ever separate us from the love of God. It is from the heart of that love in the resurrected Son of God that we may reflect on the radical nature of evil without suffering morbid mesmerization or resurrection and crucifixion events, which belong inseparably together, has behind it the incarnation, the staggering fact that God himself has come directly into our creaturely being to become one of us, for our sakes. Thus the incarnation, passion, and resurrection conjointly tell us that far from evil having to do only with human hearts and minds, it has become entrenched in the ontological depths of created existence and that it is only from within those ontological depths that God could get at the heart of evil in order to destroy it, and set about rebuilding what he had made to be good. (We have to think of that as the only way that God ‘could’ take, for the fact that he has as a matter of fact taken this way in the freedom of his grace excludes any other possibility from our consideration.) It is surely in the light of this ontological salvation that we are to understand the so-called ‘nature of miracles’, as well as the resurrection of Jesus from death, for they represent not a suspension of the natural or created order but the very reverse, the recreation of the natural order wherever it suffers from decay or damage or corruption or disorder through evil. God does not give up his claim that the creation is ‘good’, but insists on upholding that claim by incarnating within the creation the personal presence of his own Logos, the creative and ordering source of the creation, thereby pledging his own eternal constancy and rationality as the ground for the redemption and final establishment of all created reality.
We see the ontological aspect noted once again, and even further we see Torrance, in step with Barth, highlighting how even the knowledge and depth of sin can really only be understood Christologically; as we understand its depths through dwelling upon the reality of what actually was required for salvation to be accomplished. We see in this quote components that we find in Patristic thinkers like Athanasius, and even Maximus the Confessor; particularly as the latter gets into proposing things along the lines of the logoi thread that is interwoven throughout the created order as its taxis or order.
These are ways into a discussion about the atonement and salvation that are lacking, typically, in the Western mode. John Calvin, though, is an exception to this rule; and we could say this is because of his hyper-Christ concentrated approach. If a thinker genuinely focuses on the deep Christologicalness we find in the New Testament it is almost an axiom that that thinker will end up pressing into union with Christ themes that look something like what we find in Torrance’s presentation. Federal theology and the Post Reformation Reformed orthodox theology does not have this emphasis when thinking salvation; it is framed forensically and under a legal strain, necessarily, precisely because their hermeneutical system starts with a Covenant of Works only to be succeeded by the Covenant of Grace. Some will argue that this does not give Covenant theology a necessary legal character, but I think the proof is in the pudding.
