Roger Viklund and David Blocker have posted evidence from a Medieval Jewish anti-Christian work called Even Bohan that has a variant of the gospel of Matthew in Hebrew that sheds light on the possibility that Secret Mark is authentic. At least, not forged by Morton Smith:
Isn’t it an amazing coincidence that Secret Mark has parallels with the only lengthy passage from the Gospel of Mark that was incorporated into Shem Tob Matthew?
The parallel texts are about Jesus taking the hand of a seemingly dead youth, raising him, and then “coming into a house”. Furthermore, in each example, the “raising episode” is followed by Jesus offering instruction to his disciple(s) (see Matthew 17:19–21), which further emphasizes the text parallels.
Additionally, where Secret Mark fills in a narrative gap in the received Greek Text of Mark (iv); the interpolation of the Markan text into Shem Tob Matthew fills in a narrative gap in the text of Matthew by adding supplementary details about the raising of the young boy.
Finally, Shem-Tob Hebrew Matthew 17, Mark 9:20–28, and Secret Mark‘s raising of the youth, and the Raising of Lazarus in the Gospel of John (John 11) have considerable narrative overlap.
All this of course might just be due to a series of coincidences. However, these coincidences are found in a text where Jesus, while in Bethany at night, is said to have taught the disciples the Kingdom of God. One cannot help wondering if an otherwise lost tradition has been preserved at least in part in this Hebrew text of Matthew: a tradition that is also found in the Secret Gospel of Mark.
Good stuff. This is just a summary, so reading the whole thing might be more beneficial.
