Too bad Tolkein is no longer with us. He would have been perfect for the task, both from the standpoint of linguistics and devout Catholicism.
True -- if they had just consulted him to begin with about an English translation, there would have been time, but it was the 60s, after all . . . opportunities lost!
My best friend wrote a letter to C.S. Lewis back in the early 60s. I was going to, but never got around to it. He actually answered her with a very kind little note. Another opportunity lost!
