Evangelical theology is trapped in a perpetual struggle between its two uneasily coexisting traditions: biblical theology and systematic theology. The dispute is always the same. It never ceases, never disappears, never makes real progress on genuinely reconciling the traditions, but continues forever. The players come and go, the ostensible matter of controversy shifts, but the arguments never change. This is happening, in one form, right now with John Mark Comer and the New Calvinists; it happened in the last decade with the debate over the Gospel between “Team King Jesus” and “Team Gospel Coalition”; it happened in the decade before that with N. T. Wright and John Piper on justification (funny how the New Calvinists keep popping up here!); and so forth ad infinitum. Squint a bit, and even the early stages of the Reformation outline the same form of controversy: Luther the doctor of Old Testament, Zwingli the advocate of expository preaching, and so forth for the “Bible” side, and Eck, Cajetan, various Popes, et al for the “theology” side. (My personal favorite example of this is the pair of books published by IVP Academic a few years ago, authored respectively by Hans Boersma and Scot McKnight: Five Things Theologians Wish Biblical Scholars Knew and Five Things Biblical Scholars Wish Theologians Knew.)

Here is the general form of the controversy. Note that whenever it wells up and spills over, it can do so under the impulse of either tradition, but really identifying such responsibility is difficult; it is just one perpetual-motion controversy, and so the whole thing (at least when viewed as neutrally as possible) is a chicken and egg problem. However, let us suppose it is (re)triggered by the Bible side:

1. A theologian specializing in Biblical interpretation (which is all that a “biblical scholar” really is) publishes some argument, taking as his (and it is, as we know, usually a he) point of polemical departure some commonly taken-for-granted bit of doctrina, especially as it is popularly preached rather than scholastically described: for example (to pick, almost at random, from N. T. Wright), the gospel is about you “getting saved” so that you will “go to heaven when you die.” This bit of (again, popularly expressed) teaching is then found to be a remarkably inadequate representation of the biblical texts usually adduced to support it: so John 3, Romans 3–8, Revelation 21–22, and so forth actually testify that “salvation” and “eternal life” have a present dimension and reference, and the future hope is primarily for heaven “coming down to earth,” not us escaping earth and going “up to heaven”: not “life after death” so much as, in Wright’s (brilliant) phrase, “life after life after death.” Often the popular misrepresentation is straightforwardly taken to be the responsibility of some major, and beloved, historical-theological figure in the tradition: Augustine, Luther, and Calvin are popular choices here. (Sometimes it is not the (re)originator of the controversy who does this, but some less-cautious disciple.)
2. These warning shots arouse the systematic theologians from their dogmatic slumbers (noodling away over the finer points of Jonathan Edwards' doctrine of the beatific vision, or Kuyper’s theology of church offices, or whatever), and they determine to return fire. The more historically minded pursue lines of historical critique: the representation of Augustine (or whomever) is in fact a misrepresentation, and Augustine was far more careful than he is generally criticized as being. What we most need today, in fact, is not less Augustinianism, but more Augustinian Augustinianism! Or: the biblical theologian is simply and naïvely repristinating a historical error (e.g., the Hellenization thesis) which has been weighed, measured, and found wanting. The more philosophically minded, similarly, take the concepts deployed (again, simply and naïvely) by the biblical theologian and subject them to philosophical-theological critique: this is (or depends upon) univocity repristinated, or Social Trinitarianism uncritically retrieved, or Socinianism resurgent. Sometimes this sort of thing has the genuinely salutary effect of bringing the various parties' philosophical and theological presuppositions directly into view. Often it reads more like an attempt to overwhelm the opponent with force of Weighty Words.
3. Now the biblical theologians sharpen their exegetical tools to reply. There are a number of forking paths here, but they mostly consist of the same basic move: Sure, they say, you may be right about what Augustine said: but was Augustine right about what the Bible said? The systematicians are far too concerned with the neatness of their systems, far too quick to find dogmatic concepts — which took centuries to develop — in the text of the Bible itself. Or they are far too quick to occlude (here enters a historical-theological presupposition) what was imaginable, and therefore mean-able, to the author of a particular book in favor of the Church’s later consensus about what that book must really have meant: the conceptual equivalent of “illegitimate totality transfer” in semantics. This is typically where, in New Testament, references to “Second Temple Jewish” and, in Old Testament, references to “Bronze Age Israelite” thought occur: no Second Temple Jewish reader had such and such a conceptual category as to have been able to comprehend what Augustine later argued, and likewise Augustine had lost some key conceptual categories possessed by a Second Temple Jew. You know, the Hellenization thesis may be discredited in certain areas, but come on, you’re really telling me that by transposing the Biblical subject matter into the language of neo-Platonism there was not an iota, not a jot that passed from the Law’s original meaning? Are we even evangelicals anymore (rather than — horror of horrors! — Roman Catholics) if we are willing to prioritize a later theological development over what the Bible says?
4. The systematicians, of course, cannot abide this sort of suggestion. Naïve (you keep using that word) historicism! is the charge flung at the biblical theologians. You are operating from theological presuppositions just as much as we are, but the difference is a) you don’t know what yours are, whereas we do, and b) yours are wrong. Sometimes there is a historical doubling down, a sort of fighting the historicizing fire with fire: Don’t you know that your same argument about this same text was made in, say, the third century by [checks notes] Paul of Samosata? To reject Paulianist heresy, we must also reject your argument. Or: You have, damningly, overlooked a most critical distinction made in the 17th century by Francis Turretin — which convincingly vindicates our interpretation, and demolishes yours. The more thoughtful and careful systematicians, at this point, are actually usually willing to own that yes, they are willing to prioritize a later theological development (though of course for evangelicals it is that of, say, Martin Luther and not the Council of Trent, for… reasons!) because they believe it more effectively preserves some essential truth taught in the Bible — or which itself must be preserved to in turn preserve some essential truth taught in the Bible.
5. And so on, and so forth, unto the ages of ages. Eventually an individual controversy will run out of steam and settle back down under the surface. But never for long. All this has happened before, and it will all happen again.

This process — which I describe above with great love for both sides, and with tongue firmly in cheek — is a kind of dialectical expression of the basic aporia of the evangelical tradition. Belonging myself, however uneasily, to a stream of that tradition, I believe and affirm unhesitatingly every word of what follows in this paragraph, and thus belong to the realm and feel the force of the aporia. The Bible possesses a unique and singular authority, an authority distinct from and superior to any human tradition. What it speaks to us shares fully in the eternal authority of the Triune God, of Whom it testifies singularly and authoritatively and Who is singularly and authoritatively God (the Shema means more, but not less, than this). It is therefore of supreme importance to understand and obey what it is speaking. However, there is no non-traditioned, perfectly rational position from which any human can interpret the totality of what it is speaking. Add to this that the content and message of the tradition, as we now express it, is derivative from but not identical to the content and message of the Bible: it is, unavoidably, at a minimum that content and message — which was originally imparted in one moment of history — interpreted and therefore translated into a new moment of history. This renders its traditioned re-presentation remarkably contingent when viewed historically, even as such tradition is simultaneously inescapable and necessary. It is only the (theological) confession of Divine Providence which guards for us this sheer contingency from tipping into simple invalidity.

Thus, the Bible’s authority seems to be not just an article of faith but the greatest article of faith, the article of faith on which all other articles of faith depend — but simultaneously the more it becomes an article of faith, the less contact it seems to have with not only reality as historically experienced but also its own text and matter. Thence the divide between biblical and systematic theologians. The biblical theologians protest when the systematicians take the text of the Bible beyond what it presents itself to us as being; the systematic theologians protest when the biblicists set the Bible over against the articles of faith which depend upon it, which it has generated, and are in turn what we live. This dynamic is constantly re-presenting itself at the level of the matter under controversy. Take the doctrine of God. The more that, for instance, under the influence of philosophical criticism, God becomes absolutely transcendent, unqualifiedly impassible, and so forth, the less contact this God-concept seems to have with the God represented in the narratives of Scripture, which naturally invites rebuke — but equally a God-concept simply transposed out of the narratives of Scripture invites this philosophical criticism: if God were not absolutely transcendent and unqualifiedly impassible, could the sorts of exalted things Scripture says (and we are invited to say) about His faithfulness and justice and so on really be maintained?

“As ministers,” Barth remarks in one of his great early essays, “we ought to speak of God. We are human, however, and so cannot speak of God.” Put differently: we must re-present the Bible, but can we — and may we? Everyone wants to live “the religion of the Bible,” but nobody can live “the religion of the Bible” in the strictest sense of the word, because the Bible does not so much present as generate a “religion” which is both greater and lesser than itself. Nobody wants to “go beyond what is written” — but nobody can truly “not go beyond what is written,” because as soon as one asks the question “what is written?” it inevitably comes coupled with the question “how do you read it?” Both parties in the debates are permanently trapped in this dialectic. Everyone involved knows all this, at a more or less tacit level. The debates are almost entered into with a sigh of dismayed recognition, as a performance that must be undertaken yet whose non-outcome is fully known and expected. At times they seem to be an exercise in deflecting our attention from this basic aporia: like the head of Medusa, it cannot be looked at directly, hence it turn us to stone (or, yet worse, to Rome). No new Aquinas or Calvin or Barth has come along, someone who can embody both traditions so persuasively and definitively as to reconcile them and generate a new synthetic tradition of evangelical theology. Is such a reconciliation possible? Where could such a figure come from? Who is sufficient for these things?

And how, then, shall we live? For we must, we cannot but, go on with living even as we theologize, and if our theology — in all its detail and in its grand sweep — has nothing really to do with our living (if, that is, such a thing is even possible) then it is a grand experiment in foolishness, in “wise words taught by mere human wisdom.” The controversy wells up again, and again, and again because all parties recognize that in it the form of our life before God is somehow at stake. There is a way (that is, The Way) and it must be walked in. I am tempted to conclude here on a note of despair for the insolubility of this problem, and yet I cannot despair entirely. For, low and gentle, yet firm, I hear again the voice of The Way, cutting through the noise of the controversies and of my own mind, speaking the simplest words of all, inviting, beckoning, pleading: “Come to Me, all you who labor and are heavy laden, and I will give you rest.”

For this reason I do not and cannot ultimately choose a “side” in these theological controversies. Rather, wherever I encounter them — on either side — I will tend to throw in my lot with those who seek to speak and live the words of The Way after Him. I will trust in His words — His Word — to me, because there is no deeper metaphysical or ontological substrate than this trust. That is why any of us have ended up in these controversies to begin with, after all: Before we ever wrestled with the concept of history, or the hermeneutics of Biblical narrative, or the concept of God, we heard the Voice of the Way and found ourselves irresistibly drawn towards Him, found ourselves convinced that He is the Truth and the Life, came to know Him as the pearl of great value to have which it is worth selling all. And that is where we will still be after the controversies cease, when we will see no longer as in a mirror dimly but face to face.
