Continuing my engagement with T.F. Torrance toward what might be called a “scientific” missiology, I move further into the first level in which we come to understand the mission of the church in terms of its historical manifestation, of the story of redemption as it is recounted in Scripture. Central to this story, as Torrance would have it, is the notion of the church as “Body of Christ”, yet the meaning and significance of this can only be comprehended within the entire sweep of the biblical drama. Torrance writes:
The Church does not derive from below but from above, but it does not exist apart from the people that make up its membership or apart from the fellowship they have with the life of God. The Church is a divine creation but in the divine economy it did not come into being automatically with the creation of the world or all at once with the establishment in the world of a human society. The Church was formed in history as God called and entered into communion with His people and in and through them embodied and worked out by mighty acts of grace His purpose of love which He brought at last to its fulfilment in Jesus Christ.
While there is only one people and Church of God throughout all ages from the beginning of creation to the end, there are three stages or phases of its life. It took a preparatory form before the Incarnation as in the covenant mercies of the Father one people was called and separated out as the instrument through which all peoples were to be blessed; it was given a new form in Jesus Christ who gathered up and reconstructed the one people of God in Himself, and poured out His Spirit upon broken and divided humanity that through His atoning life and death and resurrection all men might be reconciled to God and to one another, sharing equally in the life and love of the Father as the new undivided race; but it is yet to take on its final and eternal form when Christ comes again to judge and renew His creation, for then, the Church which now lives in the condition of humiliation and in the ambiguous forms of this age, will be manifested as the new creation without spot or wrinkle, eternally serving and sharing in the glory of God.
Because Jesus Christ through the Spirit dwells in the midst of the Church on earth, making it His own Body or His earthly and historical form of existence, it already partakes of the eternal life of God that freely flows out through Him to all men. Because its existence is rooted in the sending of the Son by the Father to be the Saviour of the world, the Church lives its divinely given life in history as the servant of Christ sent out by Him to proclaim the Gospel of God’s love to the whole world and to be in itself as the reconciled people of God the provisional form of the new creation.
It is therefore the mission of the Church by the witness of its word and life to bring to all nations and races the message of hope in the darkness and dangers of our times, and to summon them to the obedience of the Gospel, that the love of God in Jesus Christ may be poured out upon them by the Spirit, breaking down all barriers, healing all divisions and gathering them together as one universal flock to meet the coming of the Great Shepherd, the one Lord and Saviour of all. [“The Foundation of the Church”, Scottish Journal of Theology 16, no. 2 (1963): 113-114]
Torrance’s account is succinct and dense, for here it constitutes the introduction and overview to his essay “The Foundation of the Church”. What Torrance goes on to recount is the birth and growth of the church through its three main stages: the church as Israel, the church as the Body of Christ, and the church as the glorified new humanity of God. Torrance denotes the first stage as preparatory, precisely because its goal was the coming of the Savior who would represent and embody the people of God in himself, thereby carrying it through the throes of death and into the glory of resurrection. The entire history of Israel was an ever-deepening union between a holy God and a sinful people, a combustible combination that eventually resulted in a judgment so total that only one Israelite was, so to speak, left standing: Jesus Christ, the One who represented the Many. Yet this One was no mere Israelite, indeed he was also the God of Israel, finally and fully united to humanity in a perfect and indissoluble union.
Thus, it was only after the crucifixion and resurrection of Christ in whom the reconciliation of God and humanity was realized that the church could be so united to God through Christ and in the Spirit that it could be called Christ’s “Body”. As this Body, the church is charged, while it awaits the consummation of redemption during the time of Christ’s hiddenness in heaven, with serving as his servant and herald to all the world, announcing the good news of his achievement in the flesh and on the behalf of all people. It is precisely because the church exists and serves as the Body of Christ that it must be and do nothing except which its Head is and does. Hence the need for a scientific missiology: the mission of the church must exclusively derive from and strictly conform to the mission of Christ, yet in a way proper to its dependent and submissive relation as Body.
Now there is still much further work that needs to be done in order to fully define and provide practical direction for the mission of the church, yet this is the essential starting point. The church of the present is the body of Christ, reborn from Israel through the death and resurrection of Christ and united to him by the Spirit, yet still awaiting the consummation of redemption at the parousia of Christ and the resurrection of the dead.
