Breakfast by the lake: Peter restored and the witness named

John 21 follows what reads like an ending. John 20:30-31 gives the purpose of the book, and yet a further chapter describes a fourth appearance, the restoration of Peter and the fate of the beloved disciple. Every surviving manuscript contains it, so it was part of the Gospel from the earliest circulation. Scholars explain the shape in two main ways. Some hold that the evangelist himself added the chapter as a postscript, since its vocabulary and style closely resemble the rest. Others, noting that verse 24 says 'we know that his testimony is true' and that verse 23 corrects a rumour that the beloved disciple would not die, think that disciples or editors added the chapter after his death. Both agree that the chapter belongs to the Gospel and is part of its canonical form.

The verse that speaks of authorship is 21:24: this is the disciple who testifies to these things and has written them down. Tradition from Irenaeus (about AD 180) names him as John the son of Zebedee, who, Irenaeus says, lived at Ephesus into the reign of Trajan (AD 98 to 117). Others identify the beloved disciple with the 'John the elder' mentioned by Papias, and Richard Bauckham has defended eyewitness authorship on that basis. Raymond Brown thought a community preserved his tradition. 'Has written' could mean that he caused it to be written, as Pilate 'wrote' the title on the cross. The date is generally put between AD 80 and 100.

The chapter sets the appearance in Galilee. That fits the promises in Mark 14:28 and 16:7 and Matthew 26:32 and 28:7 that the risen Jesus would go ahead of the disciples to Galilee, which Matthew 28:16 records. Luke 5:1 to 11 tells of a great catch of fish at the start of Peter's call, with details that overlap John 21. Some scholars think the two stories are versions of the same event moved to different points in the story. The Gospels themselves present them as two separate events.

John 21 is narrative with strong links back to earlier scenes, and it should be read with them in view. Peter's denial by a charcoal fire (18:15-27) is answered by a charcoal fire and three questions here. The feeding of the crowd with bread and fish (6:1-15) is recalled by the bread and fish Jesus gives. The Good Shepherd discourse (10:1-18) provides the background for the commission to Peter. The Gospel is closing in the same way it began, with disciples called to follow Jesus (1:35-51; 21:19).

Some details have been read symbolically, and the principle is to separate what the text signals from what later readers have added. The number 153 (verse 11) is the best known example. Jerome, in his commentary on Ezekiel, passed on a claim that ancient writers counted 153 kinds of fish, so that the catch would picture all nations. Augustine noted that 153 is the sum of the numbers one through seventeen and gave it a meaning related to the law and grace. These readings are old and often thoughtful but are not stated in the text, which may simply record the count, as an eyewitness would. A second principle concerns the verbs for love in Jesus' questions. Some older commentators drew a sharp line between agapao and phileo, but most current scholars hold that John uses them interchangeably (for the Father's love for the Son he uses both, in 3:35 and 5:20), so no argument should depend on the difference. A third is that the Gospel says of itself that it is selective (20:30; 21:25), so details should not be pressed beyond what the text signals.

Verses 1–14

The scene is the Sea of Tiberias, the Sea of Galilee, which took its second name from the city of Tiberias on its shore. Seven disciples are together: Simon Peter, Thomas, Nathanael from Cana (found only in John, 1:45-51), the sons of Zebedee and two others. Peter says, 'I am going fishing,' and the others join him. Whether this is a return to their old work or simply a way to get food is unclear, and the text does not judge it. They catch nothing all night. At dawn Jesus stands on the shore, but they do not recognise him. He calls them 'Children' and tells them to cast the net on the right side. The net fills so that they cannot haul it in. The beloved disciple says to Peter, 'It is the Lord!' and Peter puts on his outer garment and jumps into the sea. The others bring the boat and the net to land, about a hundred yards away. On shore they find a charcoal fire with fish and bread. Jesus asks for some of the fish they have caught, and Peter hauls the net ashore: 153 large fish, and the net not torn. Jesus says, 'Come, have breakfast.' None dares ask who he is, because they know it is the Lord. He takes the bread and gives it to them, and the fish also. John counts this as the third appearance to the disciples (verse 14). The charcoal fire (anthrakia) appears elsewhere only at 18:18, where Peter denied him.

Verses 15–19

After breakfast Jesus asks, 'Simon son of John, do you love Me more than these?' The question is ambiguous. It may mean 'Do you love me more than these other disciples do?', which recalls Peter's earlier claim to be ready to die (13:37; Mark 14:29). It may mean 'Do you love me more than you love these other disciples?' Or it may mean 'more than you love these boats and nets', the old trade he has just returned to. Peter answers, 'Yes, Lord, You know I love You,' and does not compare himself. Jesus replies, 'Feed My lambs.' He asks a second time and gives the command 'Shepherd My sheep'. The third time Peter is 'deeply hurt', and answers, 'Lord, You know all things.' The threefold question answers the threefold denial, and the repeated command makes Peter a shepherd of Jesus' flock. The sheep remain his: the possessive is 'My'.

Then Jesus foretells how Peter will die: when old, he will stretch out his hands and another will dress him and lead him 'where you do not want to go'. John explains that this signified 'the kind of death by which Peter would glorify God'. Early Christian tradition (for example 1 Clement 5 and Tertullian) takes it as martyrdom, and the later tradition places it in Rome under Nero, though details such as crucifixion upside down come from later sources. 'Follow Me' reverses the failure of 13:36 to 38 and repeats the first call.

Verses 20–23

Peter turns and sees the beloved disciple following, and asks, 'Lord, what about him?' Jesus replies, 'If I want him to remain until I return, what is that to you? You follow Me!' A rumour spread that the disciple would not die, and John corrects it: Jesus did not say that, but only 'If I want him to remain until I return, what is that to you?' The correction suggests that the disciple had died, or was near death, when the chapter was written.

Verses 24–25

'This is the disciple who testifies to these things and who has written them down. And we know that his testimony is true.' The 'we' shows a group vouching for him. The closing line, 'There are many more things that Jesus did', speaks with a first-person 'I suppose' and uses hyperbole of a kind common in ancient writing.

John 21 teaches the doctrine of restoration. Peter's failure was grave and public, and Jesus restores him without reproach but with a searching question. Forgiveness and a renewed commission go together. It also shows what pastoral ministry is: to feed and shepherd a flock that belongs to Christ, out of love for him. The Old Testament speaks of faithless shepherds and the promise that God himself will shepherd his people (Ezekiel 34; Jeremiah 23:1-4). In the New Testament Peter later exhorts elders to shepherd the flock of God, with Christ as the chief shepherd (1 Peter 5:1-4), and Paul says the same to the Ephesian elders (Acts 20:28).

The chapter treats martyrdom as a way of glorifying God (verse 19), and discipleship as following Christ without comparing oneself to others (verse 22). It also shows the risen Lord eating with his disciples, as in Luke 24:41 to 43 and Acts 10:41. The resurrection body can be touched and can eat, and the fellowship of the table continues. The catch of fish pictures the church's mission, and the net that does not break fits Jesus' earlier promise to make his followers fishers of men (Matthew 4:19) and his parable of the net (Matthew 13:47-48). Finally, the closing verse recalls the limits of the written Gospel. Scripture is a selection, enough for faith (20:31), not a record of everything Christ did.

The risen Christ appears as the Lord who knows, provides and commands. He knows what is in the nets before they are lowered, and Peter says 'You know all things', as the disciples had said in 16:30 and as John says of Jesus in 2:24. He provides the catch and breakfast, as he provided bread and fish in chapter 6. He commissions as the Good Shepherd (10:11), who laid down his life for the sheep and now entrusts them to Peter while they remain 'My sheep'. In Ezekiel 34:11 to 16 the LORD promises to seek his scattered sheep and shepherd them himself, and verse 23 promises one shepherd, David; John presents Jesus as the one who fulfils that promise.

He is also the Lord who fulfils his word. He meets them in Galilee, as he said (Mark 14:28; Matthew 26:32), and the 'Follow Me' to Peter answers Jesus' earlier words that Peter could not follow him now but would follow later (13:36). Echoes are more tentative. The charcoal fire sets the denial and the restoration side by side, which John does not state. The miraculous catch recalls Luke 5:1 to 11 and the earlier feeding in John 6. The testimony in the closing verses is the Gospel's last claim that these things are true, and it ends where the book began: with a witness to the Word who became flesh (1:14).
