"This volume will be greatly appreciated by specialists as a model of careful and detailed textual analysis. [...] At the same time, the study is set out clearly and written in an approachable style, meaning that casual readers may also appreciate the quality and value of this book as an example of the best new research in this field." - H.A.G. Houghton, University of Birmingham, in: The Expository Times 131(8) 2020"Hixson’s work is an exceptional piece of textual scholarship and a necessary volume for text-critical libraries worldwide. One cannot image any future work being conducted on the purple codices or the singular readings method without consulting this text. It is the kind of work many academics should desire to produce, and it will make a substantial contribution to its field for many years to come." - Clark R. Bates, University of Birmingham, in: RBL 2022
