"There are other books on sin, grace and free will, written from a systematic or historical perspective, but this book is unique. It focusses on the primary texts and contains substantial extracts from them. So this 'historical survey' can indeed justly be called a 'reader'. The extensive extracts enable readers to experience the writings of the early church fathers for themselves and, where they wish, go back to these writings to read more. A very useful work that is heartily recommended." Tony Lane, Professor of Historical Theology, London School of Theology
well-argued, clear and engaging. an ideal resource for teaching and writing on medieval and reformation theology, it is highly recommended Nathan Hood. Uni of Glasgow, Expository Times 131(1) october 2019
I found that Knell's representational approach to themes in sin, grace and free will was well-executed, because he took great care to address points of conflict between the thinkers, but without privileging on thinker over another. The complexity of thought presented in the selected passages "stretches our minds well beyond any automatic understanding", but Knell's didactic approach to knowledge exchange inspires that mental "stretch" by making it fulfilling.
