The Gospel of John has two endings. The epilogue at the end of chapter 20 is the first of the two epilogues; it speaks of “what has been written” and why: “these things are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.” (John 20:30) The second epilogue, in chapter 21, speaks of who has done the writing: “This is the disciple who is bearing witness about these things, and who has written these things.” (John 21:24)
But as the New Testament scholar Beverly Roberts Gaventa has put it, “Chapter 21 is, or at least appears to be, an excess ending.” This “excess ending” puts forward its own working definition of love: those who truly love Jesus are those who love his “sheep.” To love Jesus means to love those Jesus loved, just as he loved them—to tend to them with compassion, care, and concern.
In this excess ending, Jesus makes his final post-resurrection appearance in the Gospel of John. He does not return with power, as he does at the end of the Gospel of Matthew. He does not promise to rendezvous with them in their old stomping grounds in Galilee, as he does by proxy at the end of the Gospel of Mark. Nor does he return to promise power for his followers, as he does at the end of the Gospel of Luke. Jesus returns, in the excess ending of the Gospel of John, to make breakfast.
After breakfast, Jesus speaks of love. The imperative of compassion, care, and concern turns on the question of Peter’s solidarity, not his authority. Jesus asks not that Peter lead, but that Peter love—that he tend Jesus’s sheep as Jesus has tended them; love those whom Jesus has loved as Jesus has loved them, just as Jesus has loved him.
