The Reformed Conformity that flourished within the Early Stuart English Church was a rich, vibrant, and distinctive theological tradition that has never before been studied in its own right. While scholars have observed how Reformed Conformists clashed with Laudians and Puritans alike, no sustained academic study of their teaching on grace and their attitude to the Church has yet been undertaken, despite the centrality of these topics to Early Stuart theological controversy. This ground-breaking monograph recovers this essential strand of Early Stuart Christian identity. It examines and analyses the teachings and writings of ten prominent theologians, all of whom made significant contributions to the debates that arose within the Church of England during the reigns of James I and Charles I and all of whom combined loyalty to orthodox Reformed teaching on grace and salvation with a commitment to the established polity of the English Church. The study makes the case for the coherence of their theological vision by underlining the connections that these Reformed Conformists made between their teaching on grace and their approach to Church order and liturgy. By engaging with a robust and influential theological tradition that was neither puritan nor Laudian, Grace and Conformity significantly enriches our account of the Early Stuart Church and contributes to the ongoing scholarly reappraisal of the wider Reformed tradition. It builds on the resurgence of academic interest in British soteriological discussion, and uses that discussion, as previous studies have not, to gain valuable new insights into Early Stuart ecclesiology.
