Dude,
The Church never actually used the D-R in its liturgy. Before Vatican II, when all we had was the Latin Mass, the D-R could have been used when the Epistle and Gospel was proclaimed to the people. (The Epistle and Gospel were also read or sung at Mass in Latin - the Latin of the Clementine Vulgate, that is.)
After Vatican II, three versions were authorized for use in English-speaking countries: the Jerusalem Bible (1966), the RSV-CE (1965-66), and the NAB (1970). Now, in the USA, thanks to our beloved shepherds, only the Revised NAB is allowed at Mass. Why not either of the other two? Simple: NOT INVENTED HERE! The JB and RSV-CE are still used elsewhere in the English-speaking world, Deo gratias.
Why not get both an RSV-CE and a D-R? I would suggest the first edition of the RSV-CE (Ignatius, Scepter Press, Oxford), as opposed to the second, which, to me, is a "work-in-progress. It does conform in a very few places to Liturgiam Authenticam, but not enough to make a difference.
The RSV-CE is in the so-called “Tyndale- King James tradition”; dignified, not dumbed down, and NO inclusive language. Then, once you’ve read through the RSV-CE, you can tackle the D-R. Between the two, you have all the accuracy there is to “see through” to the Hebrew, Aramaic, and Greek.
