IVP, in their continued efforts to provide access to ancient Christian writing has expanded their series' Ancient Christian Commentary on Scripture and Ancient Christian Doctrine to include the more general rubric of Ancient Christian Texts. This allows IVP to specifically publish not only topical material, but selected outstanding Christian writings from the past. In this volume, we receive an anonymous 4th Century commentary on Galatians-Philemon for the first time in English. The anonymous author, dubbed 'Ambrosiaster' by the great theologian Erasmus, has produced what is arguably the finest pre-Reformation commentary on Galatians-Philemon which constitutes the majority of works in the Pauline corpus. Features include an introduction on authorship, text, translation, and social and theological context of the 4th Century, as well as notes on ambiguous references, textual difficulties, and possible errors in Ambrosiaster's text.
