When it comes to study bibles, there are three basic options available: The study notes can be printed as footnotes or endnotes, or the commentary can be printed in a separate book altogether. There are many options to choose from!
Most editions of the New American Bible Revised Edition (NABRE) feature footnotes at the bottom of each page. I suspect many young Catholics have never experienced a bible laid out differently. On the other hand, I’m aware of two editions that print all the notes at the end of each biblical book: Oxford’s Large Print NABRE (ISBN 9780195298109 — genuine leather) and the NABRE Compact edition (ISBN 9780195298031 — paperback). Because of the requirement that every Catholic bible contain resources for helping readers to understand the text, there are no editions of the NABRE printed without notes.
There are a number of other translations approved for Catholic use which are available in reader’s editions, however, with no explanatory notes. These include the RSV and NRSV. The JB and NJB are also available in reader’s editions with far fewer notes than the NJB study edition. These can be paired with a single-volume commentary like the New Jerome Biblical Commentary or the International Bible Commentary. Alternatively, multi-volume commentaries deliver even greater depth and detail. A couple well-known examples are the Catholic Commentary on Sacred Scripture series (New Testament only) and the Ignatius Catholic Study Bible (which currently has a complete set of New Testament commentaries and a partially completed set of Old Testament volumes).
What style of study notes or commentaries do you prefer? Do you use different bibles for different needs?
