John 21:23

"Then went this saying abroad among the brethren, that that disciple should not die; yet Jesus said not that he shall not die; but, If I will that he tarry till I come, what is that to thee?" "Do not thou on any account suppose," He saith, "that I order your matters after a single rule." And this He did to withdraw them from their unseasonable sympathy for each other; for since they were about to receive the charge of the world, it was necessary that they should no longer be closely associated together; for assuredly this would have been a great loss to the world. Wherefore He saith unto him, "Thou hast had a work entrusted to thee, look to it, accomplish it, labor and struggle. What if I will that he tarry here? Look thou to and care for thine own matters."

And observe, I pray thee, here also the absence of pride in the Evangelist; for having mentioned the opinion of the disciples, he corrects it, as though they had not comprehended what Jesus meant. "Jesus said not," he tells us, "that he shall not die, but, If I will that he tarry."

"Then went this saying abroad among the brethren, that that disciple dieth not: yet Jesus said not unto him, He dieth not; but, Thus do I wish him to remain till I come, what is that to thee?" You see the great extent in this Gospel of a question which, by its depth, must exercise in no ordinary way the mind of the inquirer. For why is it said to Peter, "Follow me," and not to the others who were likewise present? Who can readily believe that anything else was meant than what the brethren who lived at the time believed, namely, that that disciple was not to die, but to abide in this life till Jesus came? But John himself removed such an idea, by giving a flat contradiction to the report that the Lord had said so. For why should he add, "Jesus saith not, He dieth not," save to prevent what was false from taking hold of the hearts of men?

(Tract. cxxiv) Jesus saith unto him, What is that to thee? and He then repeats, Follow thou Me, as if John would not follow Him, because he wished to remain till He came; Then went this saying abroad among the disciples, that that disciple should not die. Was it not a natural inference of the disciple's? But John himself does away with such a notion: Yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee? But if any so will, let him contradict, and say that what John says is true, viz. that our Lord did not say that that disciple should not die, but that nevertheless this was signified by using such words as John records.

Peter hearing that he was to suffer death for Christ, asks whether John was to die: Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on His breast at supper, and said, Lord, which is he that betrayeth Thee? Peter seeing him saith to Jesus, Lord, and what shall this man do? i. e. Shall he not die? Or let him say, Christ did not deny that John was to die, for whatever is born dies; but said, I will that he tarry till I come, i. e. to live to the end of the world, and then he shall suffer martyrdom for Me. And therefore they confess that he still lives, but will be killed by Antichrist, and will preach Christ's name with Elias. But if his sepulchre be objected, then they say that he entered in alive, and went out of it afterwards. When our Lord says to Peter, Follow Me, He confers upon him the superintendence over all the faithful, and at the same time bids him imitate Him in every thing, word and work. He shows too His affection for Peter; for those who are most dear to us, we bid follow us. Some have understood, Till I come, to mean, Till I come to punish the Jews who have crucified Me, and strike them with the Roman rod. For they say that this Apostle lived up to the time of Vespasian, who took Jerusalem, and dwelt near when it was taken. Or, Till I come, i. e. till I give him the commission to preach, for to you I commit now the pontificate of the world: and in this follow Me, but let him remain till I come and call him, as I do thee now.
