Joel R. Beeke analyzes the doctrine of assurance of faith in the theology of Calvin and the Reformed tradition after him. His conclusion is that Calvin and post-Reformation Reformed theologians substantially share the teaching on assurance, differing only in matters of degree. Therefore, the teachings of 17th century Reformed theology, as characterized in chapter 18 of the Westminster Confession of Faith, is an advancement of the 16th century Reformers rather than a departure. Beeke deals with English Puritanism, and well as its Dutch counterpart known as the Nadere Reformatie (Second or Further Reformation).
