What kind of practices, emotions and self-understandings are linked to conversion? This contribution offers a set of analytical tools which help to understand processes of constructing, performing and maintaining conversionist identity. In doing so, it builds on both, source material related to 17 th and 18 th century New England and conversion research in the area of sociology, anthropology, and cultural studies. Holistic in its approach, it reconstructs conversionist piety as a social practice that builds up into pious cultures of body, emotion, and meaning-making. The analytical concepts developed on the way may prove to be a starting point for further empirical research on lived religion in Practical Theology and Religious Studies.
