Historians of early modern religion recognise the importance of the development of covenant theology in the formation of Calvinism. Harrison Perkins, who teaches systematic theology at Edinburgh Theological Seminary and serves as assistant minister of London Presbyterian Church, has recently published what promises to be one of the most important accounts of the development of Reformed covenantal thinking. His new book, Catholicity and the Covenant of Works: James Ussher and the Reformed Tradition (Oxford UP, 2020), investigates the covenant theology of James Ussher, archbishop of Armagh, and shows that the idea of a covenant of works structures in significant ways his account of predestination, Christology and soteriology.
