How might practice theories and engagement with practice contribute to and advance theological study of religion and religious life and practices? This volume explores and discusses how theological engagement with practice, theoretically as well as empirically, might profit from theories of practice developed in disciplines such as philosophy, sociology, education and organisational studies during the recent decades, but so far scarcely employed within theology. In part I, the volume unfolds key components of practice theory, especially as they have more recently been developed within sociological practice theories, reflect on their significance and potential with regard to theology. In part II, these perspectives are employed in the study of concrete religious practices - established as well as experimental religious practices, and collective as well as individual ones. By unfolding connections between theology and practice theories, and reflecting on practice theories' analytical and theoretical potential for theological study of religion, the book will be of interest for any scholar in the study of contemporary religion and practical theology.
