The description of Jesus accompanied by a young man wearing only a linen cloth - and then wearing nothing - comes up again in the
official text of Mark in chapter 14 verses 51-52: a young man in a linen cloth is seized during Jesus' arrest, but he escapes at the cost of his clothing.
As we read further I wonder if we can discern how much time passes between Secret Mark and Jesus's arrest... ?
If these two events were close together, maybe this is the same young man?
And maybe this young man is the same as "the disciple whom Jesus loved," who was the author of the gospel of John.
For me it makes the whole story come together. Suddenly these are people I can understand...
