The history of Congregationalism in early eighteenth-century Boston has long been dominated by the figure of Cotton Mather (1663–1728), the learned pastor of Boston's Second Church. From Benjamin Franklin's notice of Mather's “do-good” campaign of Christian charitable works to recent scholarly studies of Mather's closet piety, historians have measured the religious mood of the period by the yardstick of ideas, joys, and complaints in Mather's voluminous writings. In the process, some questions about the history of Congregationalism have been answered, but historical understanding of the period has been hindered by the relative lack of scholarly attention to the theology of other members of the clergy who served Boston congregations in the decades leading up to the Great Awakening. Given the fact that the Boston clergy was divided between two parties, namely the Matherians1 and those opposed to them, it should be obvious that any assessment of this stage of Congregationalism that is based primarily on the testimony of one party will be untrustworthy. My purpose here is to outline the thinking of that other party, the “catholicks,” with particular attention to how they addressed Congregationalism's most pressing issue, the nature of public piety.
