The episode of 'Bragg' to which I am refering gives little additional spectacular detail to what we already knew concerning the Qumran manuscripts. Indeed, with regard to Cave7, the mss in which are in Greek, I would welcome up to date facts. If that Cave really did contain a piece of the Gospel according to S Mark, this is of no little interest.
A fact I did not know is that Luke 1:32-35 employs terminology which we have now found at Qumran. I am convinced that there are things to be discovered about the 'Third' Gospel which 'Modern Biblical Studies' have concealed from us. But of broader, and broad, interest is the extent to which the Dead Sea Scrolls illustrate the very considerable diversity ("richness") in the Judaism of before AD 70; and, in illustrating this, give our biblical texts a fascinating contextuality. For example: there were beliefs recorded at Qumran concerning the replacement of the Temple cult ... and suggestions that in the last Days God would build a New, a Third, Temple.
And it is certainly thought-provoking to hear that the parts of the Old Scriptures which massively interested the Qumran sectaries ... the Psalms ... Isaiah ... Genesis and the rest of the Pentateuch ... were those also which meant a lot to Christians.
Think of that, Fathers, as you open your breviaries and wonder (if you do!) whether the day's pensum of psalms is rather a heavy burden!
