Bringing together a rich range of primary sources - images, liturgies, sermons, letters, eyewitness accounts, and Genevan consistory records - this book examines worship as it was taught and practiced in John Calvin's Geneva. Several of these primary sources are translated into English for the first time, offering new resources for studying Calvin and his context. Karin Maag uses Geneva as a case study for investigating the theology and practice of worship in the Reformation era. Covering the period from 1541 to 1564, the year of Calvin's death, Lifting Hearts to the Lord captures both Calvin's signal contribution to Reformation worship and the voices of ordinary Genevans as they navigated - and debated, even fought about - the changes in worship resulting from the Reformation.
