Johannes Zachhuber is Professor of Historical and Systematic Theology, University of Oxford, Faculty of Theology and Religion. He specializes in two main areas of research: the Eastern Patristic tradition up to John of Damascus and modern theology from the Reformation to the present, with a special interest in nineteenth-century German theology. The present lecture provides an example of his efforts to unite historical research on Patristic writings and currents of modern thought, in this case the Christology of Martin Luther. But he has pursued similar research in other areas: theological anthropology, ecclesiology, and the relation of theological to philosophical developments. His current research projects have to do, first, with the emergence of a Christian philosophy in doctrinal debates following the Council of Chalcedon, and second, with systematic-theological reflection on the significance of individuality for the Christian faith.

Among his writings are Theology as Science in Nineteenth-Century Germany: From F.C. Baur to Ernst Troeltsch (Oxford: Oxford University Press, 2013) and Human Nature in Gregory of Nyssa: Philosophical Background and Theological Significance (Leiden: Brill, 1999; paperback, 2014). He is one of the editors of The Oxford Research Encyclopedia on Martin Luther, 3 vols. (Oxford: Oxford University Press, 2017).
