I happen to prefer the NIV, but the KJV is excellent. When I quote I usually compare both versions, and notable differences I have found to be rare. The same theology is found in most mainline versions.
I find the NAB to be rather pedestrian, however, I think that it is the best effort to date to translate the original text and intent of the written words that we have into the English of this era.
Is there an "official" text that is used at all Masses?
You may not use the gender-neutral Bibles that seem to be all the rage today, but under what authority do you reject them? How do you know? Is it the Gnostic in you (say ahhhhh and I’ll look for him)? How in the world can you say that this Bible is good and that Bible is bad without the authority of God’s own Catholic Church telling you?
I haven't studied the gender-neutral Bibles carefully, but there does not appear to be any scholarship behind them. It appears they are being changed solely for the purpose of political correctness. That is all I need to know to reject them. At least there appears to be some serious scholarship behind most of the time tested versions out there. Now, there may be some "tweener" Bibles floating around out there that I might like or not, but I haven't run into any yet. I'm not really in the market right now to make a change. :)
Since May 19, 2002, the revised Lectionary, based on the New American Bible is the only English-language Lectionary that may be used at Mass in the dioceses of the United States, except for the current Lectionary for Masses with Children which remains in use.
The 1970 edition of the New American Bible is used in the Scripture readings and canticles of the Liturgy of the Hours (except the Benedictus, Magnificat, and Nunc dimittis.)
I am still a little fuzzy on the idea that one can simply look at a Bible and somehow determine that it is accurate or not. Or is it the tradition of growing up with KJV and comparing Bibles with that standard? What would set the Joseph Smith Bible apart from the KJV in your eyes?
