I’m not the first writer to ask, why didn’t Jesus write a book? We know he wanted his story written down and passed on because that’s what the disciples subsequently did under the influence of his Spirit. So why not start the ball rolling himself?
Or why not dictate his memoirs to Matthew or another of the literate apostles during the 40 days after his resurrection? Give them a written catechism to take to Jerusalem, Samaria and the uttermost parts of the Earth? Why make his church wait decades for secondhand and sometimes contradictory gospels (e.g. the resurrection accounts)?
Had Jesus penned his own gospel, it would have eliminated so much ambiguity and emphasized exactly what he thought was important. The subsequent eyewitness accounts could corroborate his story and the forthcoming epistles could have built upon it. There would be a clear hierarchy among holy texts. Such a book would still have been subjected to controversy and criticism; no question about that. But it would have been a more solid anchor point for the whole New Testament.
For whatever reasons, Jesus chose not to pick up a pen or confide in a scribe. Care to share your speculations as to why not?
