The simultaneous launch of the International Journal of Public Theology and its sponsoring Global Network for Public Theology represents a 'kairos' moment of opportunity for theologians and other scholars working in the emerging field of interdisciplinary theological inquiry into contemporary public issues. Such moments happen, this article argues, when a disruptive social experience calls for the response of collaborative theological inquiry into the public issues generated by such disruptions. By telling an autobiographical story of a public theologian and by reflecting on the history of the pioneering Edinburgh University Centre for Theology and Public Issues, the article identifies common factors that have led a growing number of scholars and research centres around the world to identify with the phrase 'public theology'. Such factors include a commitment to the ecclesial and the emancipatory dimensions of doing theology and employing research methods that include the marginalized as agents of social transformation.
