Grace Davie, one of the world's most influential scholars in contemporary sociology of religion, has furthered a tradition developed by David Martin and others in comparative sociology of religion and modernity in European and international perspective. Davie's writings on belief and belonging, particularly in a context outside active Church participation, have contributed important understandings of the cultural role of religion as memory and practice in contemporary European societies. Through her most recent work on new roles of religion in relation to the political, legal and welfare sectors of society, she has addressed debates on the resurgence of religion and the 'post-secular condition'. Modernities, Memory and Mutations presents an overview and critical engagement with contemporary themes in the sociology of religion which will inform current and forthcoming generations of scholars. Reflecting on how Grace Davie's contributions have influenced their own work and wider debates in the field, leading international scholars engage with themes Davie has critically explored across religious studies and mainstream sociology evolving a new research agenda for sociology of religion.
