Campbell's examination of early modern English Nonconformity urges his reader to perceive ecclesiastical history as an ongoing critical and theological conversation that can offer a fuller understanding of the period and the thinkers who animate it.

The Sixteenth Century Journal

This is a useful addition to the historiography. Where attention has concentrated on the common ground shared within the Church of England between the godly and the conformist and more recently on the internal tensions among the godly, the more fulsome criticisms, criticisms that were acted on, on behalf of the Separatists have sneaked under the radar of attention. This treatment, building on the work of scholars such as Stephen Brachlow, is a pertinent reminder; and the specific engagements with the Separatists’ writings are insightful and thought-provoking, not least in examining the tensions within the conditional loyalty of the Puritans to the Church of England.

The Catholic Historical Review

Campbell carefully documents the primary evidence and adeptly responds to the secondary literature, producing a text that is cultured and illuminating. This is a book for scholars focused on the history of ideas, the foundations for British and American political thought, or the history of English-speaking Christianity. It is a great resource for those interested in a profound historical instance of humanity's existential cry for religious freedom in an intolerant world.

Anglican and Episcopal History

This is an excellent exploration of early modern English religious nonconformity, scholarly yet accessible. It would make a great addition to any undergraduate or graduate course.

This is a richly textured study of religious nonconformity and separatism in sixteenth and early seventeenth century England. The monograph explores the definition and development of religious identity as well as the contests over religious truth in England and internationally. Campbell analyzes early modern religious and political thought in the context of recent scholarly interpretation and debate in an engaging and accessible manner. His study will benefit early modern specialists as well as those new to the field.
