Maccabees:
What is weird about the RSVCE is that is the version quoted in the cathechsim and not the NAB obviously Rome differs with the US Bishops on what is acceptable.
Your statement doesn’t really make a lot of sense. If by Rome you mean the Congregation for Divine Worship and the Discipline of the Sacraments, then clearly they don’t differ, or they wouldn’t have approved the lectionary. If by Rome you mean the Interdicasterial Commission for the Catechism of the Catholic Church, clearly they don’t differ, or they wouldn’t have approved the English translation. If by Rome you mean the pope, then I suppose it’s possible, but he has the duty to delegate responsible cardinals to head the various Vatican congregations and dicasteries.
So the relevant bodies in Rome did not differ with the US bishops. Clearly the bishops chose the different Bible translations for different purposes. Why not use the NAB in the Catechism?
It makes sense to me that the USCCB chose the RSV and NRSV for the English translation of the Catechism because
- It uses more sophisticated language, the precision of which is beneficial for scriptural study and catechetics.
- Unlike the NAB, which was translated specifically for use in the US, I believe the USCCB’s English translation of the Catechism was intended to be used throughout the English-speaking world.
Going back to point 1, I certainly prefer the RSV/NRSV to the NAB. However, I think the NAB is better suited to the lectionary. It’s simpler and more direct language can be more easily understood by an entire congregation, even children and those for whom English is a second language. Also, we’ve all heard a lector mispronounce a word or mess up the phrasing of a sentence, even outside of limited education level or accent that lectors occasionally have. I think this would be more common if the RSV were used.
So all in all, I think the NAB is good for its purpose, but definitely not the greatest for scripture study and catechetics among adults.
Getting back to the OP, I’m really not very familiar with the JB, although I’ve heard good things about it.
