Continuing on in my series exploring missional theology with T.F. Torrance, I would like, in this post, to consider one of the practical implications of what I have discussed thus far in terms of a Christological missiology. A Christological missiology is simply an understanding and practice of mission and evangelism whose methodology is shaped exclusively by the inner logic of Christ himself as he is proclaimed in his gospel. In short, the message determines the method. Now this can seem to be a fairly heady or abstract concept, so I would like to flesh it out a bit more by suggesting one concrete way in which Christology impacts missiology. Once again, we turn to Torrance to get us started:
At this point we must recall Calvin’s conception of the imago dei discussed earlier. Properly speaking, that image can be seen only in Christ. He is the imago dei in essence, but we who believe may have it by communication or by imputation or by spiritual generation. In some sense there remains traces in fallen man, but the image is really invisible in him, and only begins to shine forth in the Christian. But wherever the imago dei is to be found it is the reflex of God’s glory through response to His grace. That is the way in which it was designed to shine forth in man. Strictly speaking, therefore, the imago dei exists only in faith and will be revealed at the advent of Christ when He comes in His full glory.
If this is the case, how can we use the imago dei apart from faith to raise us up to a knowledge of God? And how can we use it independently of God’s grace and revelation in order to prepare us for that revelation, if it is only a reflex of God’s glorious grace? The very way to put out the light of God intended to exhibit God clearly to our minds is to appropriate as our own in this way what has been given to us from heaven. Therefore, on Calvin’s view, any attempt to build up a knowledge of God upon the examination of the imago dei in man himself would simply be a huge petitio principii. Within faith we know that “whatever God bestows upon us by Him belongs of right to Him in the highest degree; yea, He Himself is the living image of God, according to which we must be renewed, upon which depends our participation in the invaluable blessings here spoken of”. This means that we may use the imago dei as an analogy within faith, but only within faith, for “faith imports a knowledge of the Truth which excludes and shuts out whatever comes from men.”…”There is no other way in which God is known but in the face of Jesus Christ, who is the bright and lively image of Him…. It is not every kind of knowledge which is described here, but that knowledge which forms us anew into the image of God from faith to faith.“
Moreover, Calvin says, whatever may be left of the image of God in natural man is destroyed by the restoration of the image of God in us when we believe in Christ. That means that the image of God in which has been inverted by sin must be re-inverted. Because it is grace which strips a man of his perverted Adamic image, it is only stripped in the moment of the restoration of the true image of Christ. In other words, we are restored to the true image of God only through conformity to the death and resurrection of Christ. “Nothing is more opposed to spiritual wisdom than the wisdom of the flesh; nothing is more at variance with the grace of God than man’s natural ability, and so as to other things. Hence the only foundation of Christ’s Kingdom is the abasement of men…. We must give up our understanding, and renounce the wisdom of the flesh, and thus present our minds empty to Christ, that He may fill them.”
Inasmuch, therefore, as only by the grace of God in Christ, and not by nature, is the imago dei restored, so our knowledge of God which is bound up with this imago dei is gained by grace alone, and not by nature. And inasmuch as to put on the new man after the image of God in Christ we must put off the old man after the perverted image of Adam, so in order to know God in Christ, we must put away all preconceived notions, and all natural knowledge preceding from man independently of faith in Jesus Christ.
As should be obvious, Torrance is writing about John Calvin’s view of humanity, a doctrine that centers around the biblical affirmation that God created human beings in his image (imago dei) to be his image-bearers in creation. For Calvin (and arguably for Torrance as well), this concept of humanity as the imago dei goes to the heart of what it means to be human and has an irreducibly relation dimension. Human beings do not exist as autonomous creatures but derive their very life and significance from being rightly related to their Creator whose image they were made to reflect as a mirror. This means that the imago dei is not, strictly speaking, some innate quality that human beings possess, for they only bear God’s image to the extent that they live in trusting and obedience response to the Word of God that created them. That is to say, the only “point of contact”, so to speak, between God and humanity is the Word.
If this was true prior to the fall, how much more so after! The New Testament speaks of Christ as the true imago dei in whose image we are destined to be conformed. We do not yet know what we will be, for our minds and all the ideas that they have are thoroughly corrupted by sin. Thus, it is only by looking at Christ that we can see what true humanness really is. For those who are in Christ, their true being is hidden with him in God, and thus they now possess the imago dei only in the sense that they have it by faith in what has not yet appeared (Col. 3:3-4), of which the Holy Spirit is given as pledge and guarantee.
So what does this have to do with mission? The fact that only Christ is the true imago dei and that all else has been wholly depraved and twisted by sin means that there is no residual image or knowledge of God in fallen humanity to which we can appeal when communicating the gospel. Technically speaking, there is a sense in which the imago dei remains in fallen humanity, yet whatever does remain has only been perverted into its opposite. It is not as though humanity simply lost something super-added and now has become neutral; no, sin drives humanity’s image-bearing in a diametrically opposed direction. For this reason, any appeal to a supposed “natural” knowledge of God still residing in sinful human beings as a foundation upon which to build a Christian knowledge of God is doomed to failure. Sinful humanity will simply take any such appeal and twist it beyond recognition, ending up in a worse state than before. This would mean that apologetics, traditionally conceived, has little to no value in communicating the gospel to those who minds are blinded by the god of this world.
Since Jesus alone is the imago dei breaking in through the veil of sinful humanity, only he is the true apologetic of the gospel. It is not as though a message other than that concerning Jesus Christ (e.g. logical arguments for the existence of God) can pave the way for the gospel. The gospel never comes to ears that are in some sense ready for it; rather it breaks in with a fresh power that itself creates the ability to hear. We cannot make people more “receptive” to the gospel outside of Christ, for it is the gospel that carries with it its own receptivity-making power. Those with an ear to hear have it only because the power of God in the gospel has given it to them.
This does not mean that we should not take care in the way we share the gospel, making sure that the words and concepts that we use to convey it are in a language and idiom comprehensible to those we are trying to reach. Nor does it mean that apologetics has no valid function. Moreover, it is undeniable that preparation for the gospel can occur by means of the Holy Spirit who operates in inextricable conjunction with the ascended Christ who sits at the right hand of the Father. However, we should not deceive ourselves into thinking that anything other than “Jesus Christ and him crucified” (1 Cor. 2:2) will give sight to the blind, give hearing to the deaf, and give life to the dead. The preaching of the cross is a folly and a scandal and can only be spiritually discerned (1 Cor 1-2). And yet, it is precisely this preaching that determines “to know nothing…except Jesus Christ and him crucified” that by the Spirit carries its own power to create in its hearers the ability to see, hear, and live again.
In conclusion, we could say that this missiological principle — only Jesus is the true apologetic of the gospel — is a necessary implication of the incarnation. When the Word became flesh as dwelt among us as the true imago dei, he destroyed all pretensions to the validity of any other “natural” knowledge of either God or humanity. Since Christ and Christ alone is the Word of God to humanity and humanity’s response to God, only he is the one in whom a reconciling knowledge of God has any validity and power to save.
 T.F. Torrance, Calvin’s Doctrine of Man (Eugene: Wipf & Stock, 2001), pp.151-153. Although Torrance deals primarily with Calvin’s views, it is undeniable that he is sympathetic toward if not in full agreement with the great Reformer. Even if Torrance’s position on the validity of natural theology as a soft apologetic is hotly debated, it should be clear to everyone that he adamantly eschewed traditional natural theology and its use as a hard apologetic (i.e. using natural theology as a preambula fidei), and so the fundamental point still stands.
