Recently, little attention has been paid to the internal coherence of the theological discipline: how do the different subjects relate to each other? This is important, because in order to answer current theological questions, ideally all disciplines within theology should contribute to answering these questions in conjunction. Most proposals for a certain coherence and nature of theology as a discipline are theoretical and based upon certain philosophical or theological convictions. However, for a coherence of theology as a discipline to be actually helpful to collaboration and a joined understanding of the discipline, a view of theology should resonate with the practice of scholars in the field. Therefore, an empirical dimension to the encyclopaedia of theology is indispensable. The empirical research presented in this paper brings together data on views and practices of doing theology in a variety of contexts. In this paper I will present preliminary results from empirical research carried out at various academic theological institutions in Europe.
