After reading through the NT letters a couple of times in the NRSV, I've started reading in TNEB (The New English Bible).
My copy was released in 1970 but I picked it up second hand in the late 90s, I think.
The letters are 93 pages in the NRSV and 126 pages in TNEB with virtually identical page sizes. Its a very wordy translation and somewhat pompous from today's perspective.
I don't like it that much compared to my favourite: the NASB, or the NRSV (not my favourite) but will persevere with my project.
I'll probably go on to read at least Luke and Acts in it, maybe Revelation as well.
