Verily, verily, I say unto you, When you were young, you dressed yourself, and walked where you would: but when you shall be old, you shall stretch forth your hands, and another shall dress you, and carry you where you would not.
All Commentaries on John 21:18 Go To John 21
Augustine of Hippo
AD 430
That is, shall be crucified. And to come to this end, Another shall gird you, and carry you where you would not. First He said what would come to pass, secondly, how it would come to pass. For it was not when crucified, but when about to be crucified, that he was led where he would not. He wished to be released from the body, and be with Christ; but, if it were possible, he wished to attain to eternal life without the pains of death; to which he went against his will, but conquered by the force of his will, and triumphing over the human feeling, so natural a one, that even old age could not deprive Peter of it. But whatever be the pain of death, it ought to be conquered by the strength of love for Him, Who being our life, voluntarily also underwent death for us. For if there is no pain in death, or very little, the glory of martyrdom would not be great.
He who denied and loved, died in perfect love for Him, for Whom he had promised to die with wrong haste. It was necessary that Christ should first die for Peter’s salvation, and then Peter die for Christ’s Gospel.
