This book investigates the sacramental theology of Balthasar Hubmaier within the formative Anabaptist movement. It seeks to demonstrate that for Hubmaier the rites of the church are forefront in the development of his theology, both during his early Catholic career and during his tenure as an Anabaptist pastor and teacher. Pledge of Love analyses Hubmaier's theological education and development from Catholicism to Anabaptism and pays particular attention to his sacramental thought. The book examines the development of Hubmaier's doctrines of Eucharist, baptism and other possible signs of sacrament, concluding with a review of Hubmaier's liturgical contributions to Anabaptist worship.
