In a recent paper, A Small Encyclopedia of Theology, Maarten Wisse defines Christian theology as "an academic discipline that contributes to the understanding, preservation, and renewal of the Christian tradition with a view to the church, academy, and society." This definition differs from that of Gijsbert van den Brink, who - referring to Thomas Aquinas - describes theology as "the study of God and all things in the light of God." In this paper, I will explore how these definitions relate to each other. I will argue that the former definition can be enriched by the latter by addressing the inherent ambiguity of academic Christian theology: namely, that its purpose is to investigate divine revelation in order to gain knowledge of God, while simultaneously meeting the standards of academic research in public universities. I will contend that this tension is not a weakness but a source of vitality for theology. It reflects the conviction that knowledge of God is attainable through valid methods - such as interdisciplinary approaches from archaeology, philosophy, sociology, and other fields - while also acknowledging that this investigation is grounded in an act of faith. Furthermore, I will reflect on this renewed definition by exploring possible responses from Christian, secular, and non-Christian religious perspectives.
