if you thought the unrecorded sayings of Jesus

 If you thought the unrecorded sayings of Jesus could pass without commentary . . .

      from Farah See’s commentary on The Gospel of Thomas and Other Sayings
      of Jesus (in the Incoherent series, published by Rantrage Press, 2012,
      p. 211) –

The so-called unrecorded sayings of Jesus are often difficult to reconstruct. This one is not. It is certainly some variation of the following:

kai\ ei]pen au00toi=v o( 'Ihsou=v: o(moi&a e!stin h( basilei&a tw~n ou)ranw=n dido&nti a)ndri& a0delfw|~ au)tou= ixqu&n.

   Then Jesus said to them, “The kingdom of heaven is like a man who gave his brother a fish.”

Commentary

This is one of the shortest of the parables, very much like Matthew 13:45 – “Again, the kingdom of heaven is like a merchant searching for fine pearls” – about which Petra Bozohoff writes in her commentary on the first gospel. Bozohoff has an advantage we do not; she can read the parable in its larger context, which tells us what Matthew thought the parable must mean when he has the merchant find a pearl of great value, then go and sell all he has and buy it. So Bozohoff can comment further that the parable must be “connected with the supreme worth of the coming reign of Christ,” not, she adds rightly “that that can be purchased.” We have no such context. Still, we can be fairly certain that here Jesus is comparing the kingdom, his reign, to a fish his brother (or sister) could cook and eat. 
     Then we are reminded of the miracle of the loaves and fishes. When we give to one another as Christ gives to us, the gift may be superabundantly multiplied.
     In some ancient manuscripts, the pericope is enlarged to include a comment by Jesus on his own parable: “When asked what the parable meant, he said, ‘I do not know. You may know, someday you will know; but I do not.’” This is certainly a later addition to the parable; it is in no way to be construed as having anything whatsoever to do with what anyone has written about the parable. That includes yours truly. Present-day biblical scholarship often looks like it knows what it is talking about; usually that is a ruse.
