Craig A. Evans has an interesting, if not thought-provoking, discussion of Secret Mark that is worth reading. I am not sure where I stand on this debate. I know James Tabor and Joe Hoffmann both have different opinions about Smith, and they would know better than I would (and probably better than Evans, since they were students). But I can say I don’t accept Secret Mark as anything more than a fabrication (possibly ancient, possibly modern); I don’t believe this was part of the Markan tradition. Either way, I suspect there will be another article soon enough arguing the opposite. here is a snippet:
At the 1960 annual meeting of the Society of Biblical Literature, Morton Smith (1915–91) announced that while examining a number of old books and papers in the Mar Saba Monastery in the Judean Desert in 1958 he discovered three pages of hand-written Greek in the back of a 1646 edition of the letters of Ignatius. These pages purport to be a lost letter of Clement of Alexandria (c. 150–215), written to one Theodore, in which a longer, mystical (or “secret”) Gospel of Mark is discussed. Two passages of this work are quoted, one of which describes Jesus teaching a young man, wearing a linen sheet over his “naked” body, the “mystery of the kingdom of God.” In 1973, Smith published his find, now known as the “Secret Gospel of Mark,” in a lengthy, learned volume (Harvard University Press) and in a briefer, popular version (Harper). Although a number of scholars were willing to accept the find as authentic, or at least were willing to accept Smith’s account, a number of other scholars suspected the find was a hoax and that perhaps Smith himself was the hoaxer. The matter continues to be debated.
About half of the participants view Smith’s find with suspicion, if not as an outright hoax. These include Chilton, Jeffery, Piovanelli, and me. The other half of the participants, including the hosts, remain convinced that Smith told the truth. (The authenticity of the find itself, of course, is another matter.) On his blog, Tony has chronicled his thoughts, explaining why after hearing the papers and the discussion he still thinks Smith indeed made the discovery and that Smith was not involved in any way in a hoax.
