To this groundbreaking work, originally published by the Oxford University Press in the 1980s, the author has added a new preface and two appendices, one of which consists of extracts from Calvin's Commentaries. The author demonstrates that the English "Puritans", who he calls "experimental predestinarians", were followers of John Calvin's successor in Geneva, Theodore Beza, and not of Calvin himself. R. T. Kendall maintains that what became known as English Calvinism was largely the thought of Beza, not Calvin. His book is an important clarification of Calvin's position in relation to those who have been regarded as his followers.
