Gospel: John 21:20-25
Peter turned and saw the disciple Jesus loved following them – the one who had leaned on his breast at the supper and had said to him, ‘Lord, who is it that will betray you?’ Seeing him, Peter said to Jesus, ‘What about him, Lord?’ Jesus answered, ‘If I want him to stay behind till I come, what does it matter to you? You are to follow me.’ The rumour then went out among the brothers that this disciple would not die. Yet Jesus had not said to Peter, ‘He will not die’, but, ‘If I want him to stay behind till I come.’
This disciple is the one who vouches for these things and has written them down, and we know that his testimony is true.
There were many other things that Jesus did; if all were written down, the world itself, I suppose, would not hold all the books that would have to be written.
