"This book is the first English translation of both the fragments of Origen's commentary and the complete text of Jerome's commentary. Origen's fragments, where they exist, are placed in parallel columns with the text of Jerome on the same passages in Ephesians. By using texts from other works by Origen and texts from the debate of Rufinus with Jerome concerning the latter's dependence on Origen in his Commentary on Ephesians, the author is able to show numerous passages in Jerome's commentary which depend on Origen's commentary beyond those for which Greek fragments exist." The introduction sets Jerome's Commentary on Ephesians in the context of the controversy about Origen between Jerome and Rufinus and discusses Jerome's methodology in making use of Origen's Commentary on Ephesians. The nature of the catena manuscripts containing fragments of Origen's Commentary on Ephesians is discussed. The introduction also shows the important role that St. Paul's Epistle to the Ephesians held in Origen's theology. The book makes a significant contribution not only to scholarship on Origen and Jerome, but also to the wider question of the interpretation of scripture in the early Christian centuries.
