Last week I posed the question as to the possibility of reading T.F. Torrance’s theology of mission through his construct of the stratified (i.e. layered, multi-dimensional) nature of theological knowledge. In one sense we can say that Torrance’s stratified concept of theological knowledge follows a logic of discovery (or epistemology) rather than a logic of being (or ontology), although in reality the latter precedes the former. In other words, this approach articulates its understanding of the object in question by retracing the steps made from the lowest (experiential) to the highest level. At the highest level, one discovers the ontological basis without which the lower levels would not exist and which deepens the knowledge intuitively apprehended at those levels, yet one cannot arrive at the highest level without first passing through the lower. This twofold movement is reflected in the Trinitarian mission: from the Father through the Son in the Spirit, and then in the Spirit through the Son to the Father. The latter is that with which we experientially begin, and the former is the deeper reality which we discover through theological reflection on the latter.
If that seems a bit complex, it basically means this: we are to submit all of our missional thought and practice to the dictates of the gospel (including both the content of the gospel’s message and the underlying theo-logic that grounds it). As Torrance writes:
…the whole life and work of the Church in history must be subordinated to the content of the Gospel, and criticized and corrected according to its content, the saving person and work of Jesus Christ. If the Church is the Body of Christ, then the Church must conform to Christ in the whole of its life and work.
So thinking in terms of a stratified missiology must begin at the level of our experience of the gospel itself as it meets us in the witness of the church and the testimony of the Bible. Apart from this witness and our acceptance of it, we would have no missional theology at all. As Torrance explains:
We cannot see Jesus, for He has withdrawn Himself from our sight; and we will not see Him face to face until He comes again—but we can hear His voice speaking to us in the midst of the Church on earth. That is the perpetual miracle of the Bible, for it is the inspired instrument through which the voice of Christ is still to be heard. Jesus Christ was the Word of God made flesh, the still small voice of God embodied in our humanity, and it is that same Word, and that same voice, that is given to the Church in the Bible. It is by that voice that the Church in all ages is called into being, and upon that Word of God that the Church is founded. The Church is, in fact, the Community of the Voice of God, for it is the business of the Church to open the Bible and let the voice of Christ speaking in and through it be heard all over the world. It is the mission of the Church to carry the Bible to all nations, and to plant it in every home in the land, and by preaching and teaching, and the witness of its members, to make the Word of God audible, so that the living Voice of Jesus Christ the Saviour of men may be heard by every man and woman and child….
When we know Jesus Christ today our knowledge … derives from direct personal contact with Him and is based on personal witness about Him. We can have personal knowledge about Jesus Christ, but can we have direct personal encounter with Him and know Him personally for ourselves? Yes we can, and that is the perpetual miracle of the knowledge of Jesus Christ. But this direct personal knowledge of Jesus Christ comes when two things happen; when other people communicate to us a knowledge of Christ, and when at the same time He Himself alive comes to us, using their communication about Him as the means to reveal Himself directly and personally to us…. Because God has become man in one particular person in history, we can only know of Him through personal and historical contact with that person—our knowledge of God in Christ must be personally and historically communicated to us through a human chain of witnesses beginning with the recorded witness of the original disciples. But Jesus uses that historical witness to bring us to Him, and to convey Himself to us directly.
In this very Gospel, for example, it is John who is speaking and bearing witness to Jesus, and I am expounding what John has said, not simply in the light of what I think he said but in the light of what I have learned together with others in the Church of the meaning of the Gospel. I am influenced in my witness by the witness of others in the history of the Church, so that as we meditate upon this passage and seek to listen to its message, we do that “with all saints,” in the communion of the Spirit. But in that very communion it is Jesus Christ Himself alive, acutely and personally near, who speaks to us, and we hear and know Him face to face, invisibly as yet, but nonetheless directly and intimately. That is the perpetual miracle of the Gospel wherever it is preached. It is preached by very fallible human beings, but through their witness and in spite of their mistakes, Christ Himself comes and meets with sinners directly and enters into conversation with them just as He entered into conversation with these disciples at the very beginning of the Gospel….
This also the Gospel has to tell us, therefore: it is not enough that we should encounter Jesus personally for ourselves, meet and know Him and receive from Him all that He has to offer us; it is imperative that we go and find our brothers, our neighbours and our friends, and introduce them to Jesus as well, so that they may believe not because they have heard us speak about Him but because God uses our witness for His supernatural revelation, and as the means whereby there is direct personal encounter with the living Christ.
Torrance’s argument is well summarized by Paul’s words in his first letter to the Thessalonians (1:4-9, ESV):
For we know, brothers loved by God, that he has chosen you, because our gospel came to you not only in word, but also in power and in the Holy Spirit and with full conviction. You know what kind of men we proved to be among you for your sake. And you became imitators of us and of the Lord, for you received the word in much affliction, with the joy of the Holy Spirit, so that you became an example to all the believers in Macedonia and in Achaia. For not only has the word of the Lord sounded forth from you in Macedonia and Achaia, but your faith in God has gone forth everywhere, so that we need not say anything. For they themselves report concerning us the kind of reception we had among you, and how you turned to God from idols to serve the living and true God.
Here we see Paul saying, in not so many words, exactly what Torrance did. The Thessalonians’ knowledge of God (revealed in Christ and opposed to idols) began with their reception of the gospel preached by Paul and his missionary companions. This reception was not a mere change of ideas (as from one philosophy to another) but rather the powerful work of the Holy Spirit evident in the conviction and joy that it produced even in the midst of affliction, a result that transcended any sociological or psychological explanation. As Paul says in 2:13, “when you received the word of God, which you heard from us, you accepted it not as the word of men but as what it really is, the word of God.” They may not have clearly understood the full significance of what was happening to them in their encounter with the gospel, but they grasped, even if only on an intuitive level, that the foolish-sounding message of Paul was actually the power of the God in whose presence no idol can be countenanced any longer. Not only that, but having received the gospel as the word and power of God, they then became imitators of Paul, having been conscripted by the gospel into the service of the same.
So this is ground zero of a scientific missiology. Through the church’s witness, we who were formerly alienated from God in idolatry have come to know him as revealed in Christ and proclaimed in the gospel. When we heard in the “word of man”, we recognized it as the “word of God”. Although we may not have comprehended the exact relation between the two, or even how such a thing could be possible, we consciously entered in the sphere of God’s redemptive mission as we received the word of the gospel in the preaching of the church. As a result, we find ourselves caught up as active participants in the very same mission, transformed from mere hearers of the word into doers of the word committed to sharing and spreading throughout the world our ever-deepening understanding of the gospel of Christ.
