The development of the Federal theology of the late sixteenth and early seventeenth centuries was a significant transformation in Reformed theological thinking. According to the Federal theologians, all of human history could be described using the rubric of a series of covenants, or foedera, beginning with a `covenant of works' in the perfection of Eden and concluding with the new covenant fulfilled by Jesus Christ in the New Testament. The new covenant was in effect the conclusion of the `covenant of grace', and it was this which united the Old and New Testaments into one continuous epic of God's grace and mercy. While John Calvin and many earlier Reformers discussed the importance of the postlapsarian covenant of grace, they never taught the Federal theology with its key identifying feature of a prelapsarian covenant. This book traces the prelapsarian covenant idea in Reformed theology from its first use by Zacharias Ursinus in 1562 to its flowering in 1590. Besides its origins, the implications of the Federal theology for Reformed thinking are made clear, and it is shown that the idea of covenant could have important implications for areas such as church and state, the sacraments, the Puritan doctrine of conversion, the Christian Sabbath, and the doctrine of justification and Christian ethics. The Federal theology is of considerable historical importance in intellectual history and forms the framework for much of the Reformed theology in the English-speaking world for three centuries. The doctoral thesis out of which this book developed won the Frank S. and Elizabeth D. Brewer Prize of the American Society of Church History.

The idea of covenant was at the heart of early New England society. In this singular book David Weir explores the origins and development of covenant thought in America by analyzing the town and church documents written and signed by seventeenth-century New Englanders. Unmatched in the breadth of its scope, this study takes into account all of the surviving covenants in all of the New England colonies. Weir's comprehensive survey of seventeenth-century covenants leads to a more complex picture of early New England than what emerges from looking at only a few famous civil covenants like the Mayflower Compact. His work shows covenant theology being transformed into a covenantal vision for society but also reveals the stress and strains on church-state relationships that eventually led to more secularized colonial governments in eighteenth-century New England. He concludes that New England colonial society was much more "English" and much less "American" than has often been thought, and that the New England colonies substantially mirrored religious and social change in Old England.
