For much of European Christian history, asceticism has been associated with the capacity to transform individuals as well as societies. As an organised collaborative exercise in monasteries, asceticism enabled monks not only to live a life preparing for eternal life but also to generate ground-breaking technical and social innovations. Drawing on identity theories and recent developments in the social movement literature, we examine how asceticism has been the impetus for various individual and societal transformations and explore whether asceticism can still unfold such transformative power.
