Yet, in continuity with the ancient church, there is no final division between biblical interpretation and theological reflection, for they are united in the common task of attending to the subject matter of scripture. Their actual relationship is thus dialectical, in the sense that within their respective foci there exists a constant movement between the particulars of the biblical text and the whole of systematic reflection in an effort to do justice both to the exegetical thickness of doctrine and the theological coherence of biblical exegesis. [C. Kavin Rowe and Richard B. Hayes, Biblical Studies: Chapter 24, in The Oxford Handbook of Systematic Theology, edited by Webster, Tanner, Torrance, p. 452]
In the essay, both Rowe and Hays speak quite approvingly of both Barth and Bultmann of being thinkers who brought together (in their own ways) the task of theologizing and biblical studyizing; that in the modern period (from which they both were birthed) had been divided – as much as the 'historical Jesus' had been from the 'Jesus of faith'. To see biblical studies and systematic theology implicating each other – as we ought – is really to engage in a 'theology of retrieval. Meaning, as Rowe and Hays suggest through their historical development, that Barth & co. engaged in the process of retrieving the doing of biblical exegesis and theology (together) from the Patristic and Reformed periods; but in a way that also did the "retrieving" from a particular situation of development itself. So that this "retrieval" of thinking biblical studies and systematic theology together has taken shape with the full realization of all of the interpretive advances made, even in the modern period itself. The result, really, is that theological exegesis should be the only way Christian thinkers and readers engage the text of scripture and their respective thinking of the God revealed in Christ that scripture finds its scope through.
