text: There could be one common source for the Gospel books; however, by "a single provenance at some point in time," I meant either originated OR edited by a single party. Think of the narrow aperture in an hour glass. There may have been earlier texts, but at some point in time all that survives now passed through only one editor. I can't prove it of course, but there appear to be cross-book number sets that would not likely yield the Sower's Sevens unless deliberately arranged by one hand, e.g. the numbers in the six stories of the loaves and fishes comprise a single number set. The results could be random findings of a rare factor (70 x 7) but the odds are against it.
  
  "The Lost Gospel" has Paul and the Magdalene as opponents, with her the true heir to her husband Jesus' preaching re holy marriage, and Paul a morbid reactionary focused on death, and she was the founder of all that was Gnostic, if I remember correctly. The authors go on at great length to propose this -- a different view.
