This article addresses the question of whether ecumenical theological education may be a practice of peace. Beginning with the potential of religious belief to reinforce entrenched positions and to end in violence, it advocates instead the transformative practices of witness and risk. These practices have the potential to overcome the impasse between commitment and critique, between trust and suspicion. The core methodology of the article is reflection on practice in context. The contexts addressed are a consultation held in 2005, "Learning Confidence in Difference: Teaching Theology in an Ecumenical Context," and the context of its host body, the Cambridge Theological Federation (Cambridge, UK).
