The Westminster Assembly (1643–1653) met at a watershed moment in British history, at a time that left its mark on the English state, the puritan movement, and the churches of England, Scotland, and Ireland. The Assembly also proved to be a powerful force in the methodization and articulation of Reformed theology. Certainly the writings of the gathering created and popularized doctrinal distinctions and definitions that—to an astonishing degree and with surprising rapidity—entered the consciousness and vocabulary of mainstream Protestantism. The primary aim of this series is to produce accessible scholarly monographs on the Westminster Assembly, its members, and the ideas that the Assembly promoted. Some years ago, Richard Muller challenged post Reformation historians to focus on identifying “the major figures and the major issues in debate—and then sufficiently [raise] the profile of the figures or issues in order to bring about an alteration of the broader surveys of the era.” This is precisely the remit of these Studies on the Westminster Assembly, and students of post-Reformation history in particular will be treated to a corpus of material on the Westminster Assembly that will enable comparative studies in church practice, creedal formulation, and doctrinal development among Protestants. This series will also occasionally include editions of classic Assembly studies, works that have enjoyed a shaping influence in Assembly studies, are difficult to obtain at the present time, and pose questions that students of the Assembly need to answer. It is our hope that this series—in both its new and reprinted monographs—will both exemplify and encourage a newly invigorated field of study and create essential reference works for scholars in multiple disciplines.
