Mp: How many christian churches read or discuss what the dead sea scrolls contain? The anser is none, because they dont want the rank and dumb to know the truth about their origins.
Can't speak for other churches, but the LDS (Mormon) church is certainly an exception. Not only do we study the scrolls, we publish scores of scholarly papers and articles on them. We also publish extensively on the Qur'an and the Nag Hammadi library found about the same time the Dead Sea Scrolls were found (circa 1947). In fact, the Book of Mormon prophesies that such records would come forth:
And after it had come forth unto them I beheld other books, which came forth by the power of the Lamb, from the Gentiles unto them, unto the convincing of the Gentiles and the remnant of the seed of my brethren, and also the Jews who were scattered upon all the face of the earth, that the records of the prophets and of the twelve apostles of the Lamb are true. (1 Nephi 13:39)
You seem to feel these writings discredit Christianity; however, our own scholars have found just the opposite. I also know that the Catholic Church also has considerable interest in these writings; however, whether their papers are as readily available to its members I don't know. I do know that Father George McRae came to BYU years ago to speak on the Nag Hammadi writings and the place was packed. Unfortunately, most of their papers are published in expensive journals and aren't available for download.
