Bringing together top Catholic theologians in the fields of interreligious dialogue and comparative theology, the book explores the ways in which personal relationships and the 'dialogue of life' are essential for theology. Here, Catholic theologians tell the personal stories of their interreligious friendships and explore the significance of their friendships for their own life and work, filling a major hole in theological endeavors. Comparative and interreligious theologies have positioned themselves as more concrete and engaged alternatives to the theology of religions, a field that articulates a theological system for understanding religions other than one's own. Yet, comparative theology has been reserved for a select few specialists, while academic interreligious dialogue all too often focuses on the theologies and practices of religions without engaging people concretely in their lives.
