Book excerpt: This book reconstructs the connection between religion and migration, drawing on post-colonial perspectives to shed light on what religion can contribute to migrant encounters. Examining the resources and motives for hospitality as lived in Christian contexts in the Nordic region, it addresses the content of talk about religion in public discourse, the concept having become something of an empty signifier in debates surrounding migration. Multidisciplinary in approach, this volume demonstrates that religion is not, in fact, an empty signifier, but gains substance through practice and interpretation. Considering the undeveloped potentiality of religion and the manner in which the unseen religious perspective in secularity becomes manifest in practice, this volume will appeal to social scientists and scholars of religion with interests in migration, refugee studies, theology, and Christian practice.
