A commentary is a book that gives information about passages in the Bible. It follows the text chapter-by-chapter, verse-by-verse and gives definitions, explanations, background material, Church teaching and more on each passage of Scripture.
Thanks to Kevin Lay of Scepter Publishers (http://www.scepterpublishers.org/) I have a review copy of a great new one-volume commentary on the New Testament.
The title of the book is “The Navarre Bible New Testament.” I highly recommend that all Catholics have a copy of this commentary for their daily study of the Bible. It will help you understand the Bible in the heart of the Church.
You can learn more here. (I’ll have a better picture of the book as soon as I get home :-)
