An unusual, readable, and highly effective sourcebook. David M. Gwynn sets the key testimonies within a continuous narrative that provides both essential context and clear guidance as to how to read the evidence. It is a book that can be read with pleasure from cover to cover or serve as a sourcebook on any specific aspect of the early Church. -- Bryan Ward-Perkins, Fellow and Tutor in History, University of Oxford, UK and author of The Fall of Rome and the End of Civilization (2005) Offering a critically framed selection of Late Roman Christian texts, this volume offers a current as well as comprehensive overview of the issues, authors, and problems of Christianization from the third to seventh centuries. David M. Gwynn has helpfully distilled much recent scholarship into a lively narrative of this transitional era, presenting traditional texts and authors in an accessible framework as well as presenting a broad bibliography for further reading. -- Rebecca Lyman, Samuel Garrett Professor of Church History emerita, Church Divinity School of the Pacific, California, USA
