'[ T]his is a brilliant first volume of an important new series. Clearly laid out, nicely written, and throughout comprehensive, this is an excellent introduction into what early church thinkers actually though about sin, grace and free will. I would recommend it to those studying in these areas, as well as to pastors thinking deeply about these issues or perhaps wrestling with them themselves. Matt writes from his own perspective, but lets the sources speak for themselves, and is keen for the readers to make their mind up. I look forward to the next volume, and the next phase of church history. Knell is an able and warm guide!' - Thomas Creedy, www.thomascreedy.com, December 2017
'Reading this book could be helpful for those who have not really studied the early fathers. This book will certainly expose them to a plethora of original sources and in this manner, Knell's book can be considered a success.' Herzer, Mark A. PhD, Pastor of Christ Covenant Presbyterian Church in Warminster PA. The Confessional Presbyterian, pg226, Volume 14, 2018
Knell Should be commended for his hard work in collecting the various quotations and passages contained within this volume. -Andrew C. Chronister, Theologische Revue
