Examples of Interaction between Biblical Studies and Systematic Theology from Ecumenical Dialogue While Systematic Theology often draws explicitly on the results of Biblical Studies, the work of Biblical Studies is informed by Systematic Theology in less explicit ways. The distinction between Biblical Studies and Systematic Theology is institutionalized in such a way that not only do they work separately, but there is no common ground where they are compelled to meet. The situation is different in the area of ecumenical dialogue. Here, academic delegations of churches are formed to explore controversial issues in ways that bring together exegetical, historical, and systematic questions and investigations. Therefore, ecumenical dialogues and dialogue reports are a resource for the empirical study of the interdisciplinary interaction. The hypothesis of this paper is that the interaction can be read in terms of the sociological dynamics of regulation and self-regulation. This is demonstrated in two prominent examples of ecumenical dialogue: (1) the issue of sola fide and forensic justification, and (2) the role of Peter in the New Testament and the implications for the discussion of the ministry of universal oversight. While the analysis could serve as a model for the study of other examples, it could also help to implement the lens of regulation and self-regulation as a tool to perceive the existing interaction between biblical studies and systematic theology in new ways.
