This book's central argument is that oral forms of collective memory in Christian-Muslim engagements in orally-oriented societies are more effective than interreligious dialogue through the dominant written text based on elite-based concepts. The approach has dominated interreligious interactions. From the perspective of the social scientific study of interreligious encounters & collective memory in folklore studies, this book explores how orality and social remembrance articulated through folksong, oral narrative, and ritual performance strengthen interreligious engagements in the post-conflict society. The approach proposed in this book reclaims interreligious engagements based on the local Indonesian dynamic preserved in ritual performance, oral narrative, and folksong. This method articulates a contextualized interreligious engagement grounded in local culture.
