The departure of the Spirit from theology can occur in two ways.
The first possibility is that theology, whether it is primitive or exceedingly cultivated, whether old-fashioned or, perhaps, most fashionable, will no doubt be practiced more or less zealously, cleverly, and probably also piously. In any case it will certainly be occasionally reminded of the problem of the Holy Spirit. Yet this theology does not muster the courage and confidence to submit itself fearlessly and unreservedly to the illumination, admonition, and consolation of the Spirit. It refuses to permit itself to be led by him into all truth. By such refusal, theology fails to give, in its inquiry, thought, and teaching, the honor due the Spirit of the Father and the Son that was certainly poured out over all flesh for its sake. One moment theology stands in out-and-out fear of the Spirit; in another it plays dumb, perhaps pretending to be better informed or else becoming obstinate in open opposition to him. As soon as the Spirit begins to stir within it, it suspects the danger of fanaticism; or it may rotate in circles of historicism, rationalism, moralism, romanticism, dogmaticism, or intellectualism, while “round about lies green and pleasant pasture” (from Goethe’s Faust, Part One).
When theology poses and answers the question about truth in the above style and manner, it certainly cannot be serviceable to the community which, like itself, is totally dependent on the Holy Spirit. Its effect will be just the opposite! If theology is in the same situation as those disciples of John in Ephesus, who reportedly did not even know that there was a Holy Spirit, then theology must inevitably open the door to every possible, different, and strange spirit that aims at nothing other than to disturb and destroy the community, the church, and itself. Unpleasant consequences cannot and will not be lacking! Human criticism, mockery, and accusation, to be sure, cannot help theology when it is in this predicament. Only the Spirit himself can rescue theology! He, the Holy One, the Lord, the Giver of Life, waits and waits to be received anew by theology as by the community. He waits to receive from theology his due of adoration and glorification. He expects from theology that it submit itself to the repentance, renewal, and reformation he effects. He waits to vivify and illuminate its affirmations which, however right they may be, are dead without the Spirit.
The second possibility is that theology may know only too well about the rival power of the Spirit, which is indispensable to Christianity, to every Christian, and to it as well. Just because of this familiarity, theology may once again fail to acknowledge the vitality and sovereignty of this power which defies all domestication. In such a situation theology forgets that the wind of the Spirit blows where it wills. The presence and action of the Spirit are the grace of God who is always free, always superior, always giving himself undeservedly and without reservation. But theology now supposes it can deal with the Spirit as though it had hired him or even attained possession of him. It imagines that he is a power of nature that can be discovered, harnessed, and put to use like water, fire, electricity, or atomic energy. As a foolish church presupposes his presence and action in its own existence, in its offices and sacraments, ordinations, consecrations and absolutions, so a foolish theology presupposes the Spirit as the premise of its own declarations. The Spirit is thought to be one whom it knows and over whom it disposes. But a presupposed spirit is certainly not the Holy Spirit, and a theology that presumes to have it under control can only be unspiritual theology.
The Holy Spirit is the vital power that bestows free mercy on theology and on theologians just as on the community and on every single Christian. Both of these remain utterly in need of him. Only the Holy Spirit himself can help a theology that is or has become unspiritual. Only the Spirit can assist theology to become enduringly conscious and aware of the misery of its arbitrary devices of controlling him. Only where the Spirit is sighed, cried, and prayed for does he become present and newly active.
Veni creator Spiritus! “Come, O come, thou Spirit of life!” (title of a hymn by Heinrich Held, 1658). Even the best theology cannot be anything more or better than this petition made in the form of resolute work. Theology can ultimately only take the position of one of those children who have neither bread nor fish, but doubtless a father who has both and will give them these when they ask him. In its total poverty evangelical theology is rich, sustained, and upheld by its total lack of presuppositions. It is rich, sustained, and upheld, since it lays hold on God’s promise, clinging without skepticism, yet also without any presumption, to the promise according to which—not theology, but—“the Spirit searches all things, even the deep things of God.”
