I found these words from N.T. Wright fascinating even though I am not sure I agree. He is talking about the start of Jesus’ lengthy prayer in John 17 where Jesus refers to himself in the third person as “Jesus the Messiah”:
“Nor, we may suppose, is John remembering it all without having prayed through it himself, over and over again. The mention of ‘Jesus the Messiah’ in verse 3 sounds very strange from Jesus himself; perhaps here, and maybe elsewhere too, John the praying teacher, in order to make the prayer his own and pass it on to his own followers, has turned phrases round so that they become (so to speak) prayable by the continuing community. -John for Everyone: Chapters 11-21, 91-92
I don’t think I wholly agree that these words did not come out of the mouth of Jesus as recorded in John’s Gospel. If John recorded his own “prayer time version” of what some have properly called “The Lord’s Prayer” wouldn’t it make sense that he would have then changed more of the pronouns in the prayer to fit coming from his own lips in subsequent prayers? Why not change the “they’s” to “our’s” throughout? It is not uncommon for Jesus to refer to himself in the third person in the Gospels. But it is an interesting thing to wonder about. Did John pray this prayer in later years? Or is that our own presuppositions of years of Christian groups praying verbatim prayers from scripture stretching that out over the text and missing the plain meaning of Jesus’ own words?
