an introductory paragraph that lists the questions or topics discussed. He systematically discusses each question under its own heading, and most of the time, each section ends with its own conclusion. A final summary reminds the reader of what has been covered throughout the chapter. Van Loon’s method of research is through meticulous word study. He constantly and heavily uses the digital library of Greek literature, the Thesaurus Linguae Graecae (TLG). For example, he began his study of mystagogy by consulting TLG (in 2011 and 2015) on the occurrence of the string mustag in the Greek corpus. He reports that 20% of the hits came from authentic works of Cyril of Alexandria (24). He goes on to compare the occurrence of such terms among other Greek writers. He meticulously analyzes each term’s occurrence within its textual context. Then he presents to the reader the conclusion of his analysis. Van Loon’s previous book on Cyril, The Dyophysite Christology of Cyril of Alexandria (Brill, 2009), has significantly informed this work. He presented some of the chapters of the present work in various conferences. Chapter 4 was presented at the Center of Patristic Research in August 2014 and chapter 5 at the International Conference on Patristic Studies in Oxford in August 2015. As was noted, his study on Cyril’s mystagogy in chapter 2 was published in van Geest, Seeing through the Eyes of Faith. The book reads like a collection of essays by one author discussing various aspects of the theme of mystagogy. Overall, his book is well organized and his research approach is methodical and clear. He made excellent use of TLG resources. He includes themes of interest to Cyril, such as living in virtue (chapters 4 and 5), free will (chapter 4), and biblical exegesis (chapter 3), since Cyril is primarily a biblical exegete.
