Off on a tangent, but I was kind of surprised that the only English Bible on the Vatican Website was the NAB.
The USCCB owns the copyright on the NAB and the NABRE. I’m willing to bet they let the Vatican place the NAB on their website at little to no cost. The copyright holders of other translations may not have been willing to do that. Or maybe the Vatican just decided to go with the English translation that is actually owned by the bishops and didn’t even try any others. Who knows?
I think that on this forum, the faults of the NAB tend to get overstated. It’s not as literal a translation as say the RSV:CE, but it’s far from a paraphrase. And I don’t think anyone is going to venture off into heresy by reading it.
The main problems are with the
notes (not the translation itself). As RPRPsych, my main problem with them is that they present speculation about authorship, dating, etc. as though it is fact. Sure, it is one possibility – one that many, if not most, modern day scholars hold. And I know they have their reasons for those opinions. But it’s far from a unanimous consensus.
My opinion (for whatever it’s worth) is that uncritically disseminating such theories to the average layman without much additional explanation is potentially problematic (
potentially, though it may not always or even often cause problems). I like the way the Ignatius Study Bible handles things better. Even though it is clear that they hold to a certain perspective, they still let people
know about the other perspectives.
As far as what translation you want to get, that depends on what you’re looking for. I don’t think getting the NAB (or NABRE) is going to lead you into heresy. It’s probably the most readable Catholic translation in English. I think the RSV:CE is pretty readable, too. That’s my preferred translation. A lot of people like the Douay-Rheims. If you like the older language (lots of thees and thous), then you might like it.
As far as your current Bible, I have several Bibles in bad shape. I still hold onto them, though. A loose cover and couple of loose pages still seems like pretty
good shape to me.

If you really want to free up your shelf space, though, you could always give it to your priest. He’ll know what to do with it.
