1 With this third manifestation of Himself by the Lord to His disciples after His resurrection, the Gospel of the blessed Apostle John is brought to a close, of which we have already lectured through the earlier part as we were able, on to the place where it is related that an hundred and fifty-three fishes were taken by the disciples to whom He showed Himself, and for all they were so large, yet were not the nets broken. What follows we have now to take into consideration, and to discuss as the Lord enables us, and as the various points may appear to demand. When the fishing was over, “Jesus says unto them, Come [and] dine. And none of those who sat down dared to ask Him, Who are You? knowing that it was the Lord.” If, then, they knew, what need was there to ask? And if there was no need, wherefore is it said, “they dared not,” as if there were need, but, from some fear or other, they dared not? The meaning here, therefore, is: so great was the evidence of the truth that Jesus Himself had appeared to these disciples, that not one of them dared not merely to deny, but even to doubt it; for had any of them doubted it, he ought certainly to have asked. In this sense, therefore, it was said, “No one dared to ask Him, Who are You?” as if it were, No one dared to doubt that it was He Himself.
2. “And Jesus comes, and takes bread, and gives them, and fish likewise.” We are likewise told here, you see, on what they dined; and of this dinner we also will say something that is sweet and salutary, if we, too, are made by Him to partake of the food. It is related above that these disciples, when they came to the land, “saw a fire of coals laid, and a fish laid thereon, and bread.” Here we are not to understand that the bread also was laid upon the coals, but only to supply, They saw. And if we repeat this verb in the place where it ought to be supplied, the whole may read thus: They saw coals laid, and fish laid thereon, and they saw bread. Or rather in this way: They saw coals laid, and fish laid thereon; they saw also bread. At the Lord's command they likewise brought of the fishes which they themselves had caught; and although their doing so might not be actually stated by the historian, yet there has been no silence in regard to the Lord's command. For He says, “Bring of the fishes which you have now caught.” And when we have such certainty that He gave the order, will any suppose that they failed to obey it? Of this, therefore, the Lord prepared the dinner for these His seven disciples, namely, of the fish which they had seen laid upon the coals, with an addition thereto from those which they had caught, and of the bread which we are told with equal distinctness that they had seen. The fish roasted is Christ having suffered; He Himself also is the bread that comes down from heaven. With Him is incorporated the Church, in order to the participation in everlasting blessedness. For this reason is it said, “Bring of the fish which you have now caught,” that all of us who cherish this hope may know that we ourselves, through that septenary number of disciples whereby our universal community may in this passage be understood as symbolized, partake in this great sacrament, and are associated in the same blessedness. This is the Lord's dinner with His own disciples, and herewith John, although having much besides that he might say of Christ, brings his Gospel, with profound thought and an eye to important lessons, to a close. For here the Church, such as it will be hereafter among the good alone, is signified by the draught of an hundred and fifty-three fishes; and to those who so believe, and hope, and love, there is demonstrated by this dinner their participation in such super-eminent blessedness.
3. “This was now,” he says, “the third time that Jesus showed Himself to His disciples after that He was risen from the dead.” And this we are to refer not to the manifestations themselves, but to the days (that is to say, taking the first day when He rose again, and the [second] eight days after, when the disciple Thomas saw and believed, and [the third] on this day when He so acted in connection with the fishes, although how many days afterwards it was that He did so we are not told); for on that first day He was seen more than once, as is shown by the collated testimonies of all the evangelists: but, as we have said, it is in accordance with the days that His manifestations are to be calculated, making this the third; for that [manifestation] is to be reckoned the first, and all one and the same, as included in one day, however often and to however many He showed Himself on the day of His resurrection; the second eight days afterwards, and this the third, and thereafter as often as He pleased on to the fortieth day, when He ascended into heaven, although all of them have not been recorded in Scripture.
4. “So when they had dined, He says to Simon Peter, Simon, [son] of John, do you love me more than these? He says unto Him, Yea, Lord; You know that I love You. He says unto him, Feed my lambs. He says to him again, Simon, [son] of John, do you love me? He says unto Him, Yea, Lord; You know that I love You. He says unto Him, Feed my lambs. He says unto him the third time, Simon, [son] of John, do you love me? Peter was grieved because He said unto him the third time, Do you love me? And he said unto Him, Lord, You know all things; You know that I love You. He says unto him, Feed my sheep. Verily, verily, I say unto you, When you were young you girded yourself, and walked whither you would, but when you shall be old, you shall stretch forth your hands, and another shall gird you, and carry you whither you will not. And this spoke He, signifying by what death he should glorify God.” Such was the end reached by that denier and lover; elated by his presumption, prostrated by his denial, cleansed by his weeping, approved by his confession, crowned by his suffering, this was the end he reached, to die with a perfected love for the name of Him with whom, by a perverted forwardness, he had promised to die. He would do, when strengthened by His resurrection, what in his weakness he promised prematurely. For the needful order was that Christ should first die for Peter's salvation, and then that Peter should die for the preaching of Christ. The boldness thus begun by human temerity was an utter inversion of the order that had been instituted by the Truth. Peter thought to lay down his life for Christ, the one to be delivered in behalf of the Deliverer, seeing that Christ had come to lay down His life for all His own, including Peter also, which, you see, was now done. Now and henceforth a true, because graciously bestowed, strength of heart may be assumed for incurring death itself for the name of the Lord, and not a false one presumptuously usurped through an erroneous estimate of ourselves. Now there is no need that we should any more fear the passage out of the present life, because in the Lord's resurrection we have a foregoing illustration of the life to come. Now you have cause, Peter, to be no longer afraid of death, because He lives whom you mourned when dead, and whom in your carnal love you tried to hinder from dying in our behalf. You dared to step in before the Leader, and you trembled before His persecutor: now that the price has been paid for you, it is your duty to follow the Buyer, and follow Him even to the death of the cross. You have heard the words of Him whom you have already proved to be truthful; He Himself has foretold your suffering, who formerly foretold your denial.
