The article examines the relationship between ecumenical dialogues and embodied ecumenical practices. By utilizing Michel de Certeau’s theory of strategy and tactics, the authors construct a hermeneutic that aims at forming ecumenists and clarifying the object of their discourse. Specifically, unauthorized practices of collaboration between denominations (i.e., ecumenical tactics) are seen as a formative source for ecumenical dialogue (i.e., strategic ecumenism).
