This article maps two distinct bodies of thought before moving to a synthesis discussion, which proceeds in dialogue with the contributions of Pope Francis to fostering substantive peace. The first section presents select challenges and promises of employing inter-religious dialogue as a tool for peacebuilding. The article then positions papal contributions coupling inter-religious dialogue and peacebuilding. A synthesis section analyzes how Francis is buttressing this connection in particular ways with reference to his notion of building up cultures of dialogue and encounter. The results of this approach will be of interest to nonviolent activists, conflict transformation practitioners, religious studies scholars, and others concerned with dialogue's potential as a path to peace.
