In Giles Firmin and the Transatlantic Puritan Tradition, Jonathan Warren Pagán offers an intellectual biography of Giles Firmin (1613/14–1697), who lived in both Old and New England and lived through many of the transitions of international puritanism in the seventeenth century. By contextualizing Firmin in his intellectual milieu, Warren Pagán also offers a unique vantage on the transition of puritanism to Dissent in late Stuart England, surveying changing approaches to ecclesiology, pastoral theology, and the ordo salutis among the godly during the Restoration through Firmin’s writings.
