(Hom. lxxiii. 3) Great is love, and stronger than fire; nothing can stop its course. Peter the most ardent of all, as soon as he hears our Lord say, Whither I go ye cannot follow Me now, asks, Lord, whither goest Thou?
(Hom. lxxii. 1) Peter, on receiving this answer, does not check his desire, but hastily conceives favourable hopes from it, and having got rid of the fear of betraying our Lord, feels secure, and becomes himself the interrogator, while the rest are silent: Peter said unto Him, Lord, why cannot I follow Thee now? I will lay down my life for Thy sake. What sayest thou, Peter? He hath said, thou canst not, and thou sayest, thou canst: wherefore thou shalt know by experience, that thy love is nothing, unless thou art enabled from above: Jesus answered him, Will thou lay down thy life for My sake?
(Hom. lxxiii. 1) It is manifest that our Lord permitted Peter's fall. He might have recalled him to begin with, but as he persisted in his vehemence, though He did not drive him to a denial, He let him go without assistance, that He might learn his own weakness, and not fall into such sin again, when the superintendence of the world had come to him, but that remembering what had happened to himd, he might know himself.
A great thing is love, and stronger than fire itself, and it goeth up to the very heaven; there is no hindrance which can restrain its tearing force. And so the most fervent Peter, when he hears, "Whither I go ye cannot come," what saith he? "Lord, whither goest thou?" and this he said, not so much from wish to learn, as from desire to follow. To say openly, "I go," he dared not yet, but, "Whither goest thou?" Christ answered, not to his words, but to his thoughts. For that this was his wish, is clear from what Christ said, "Whither I go thou canst not follow Me now." Seest thou that he longed for the following Him, and therefore asked the question? And when he heard, "thou shalt follow Me afterwards" not even so did he restrain his longing, and, though he had gained good hopes, he is so eager as to say, "Why cannot I follow Thee now? I will lay down my life for Thee."
When he had shaken off the dread of being the traitor, and was shown to be one of His own, he afterwards asked boldly himself, while the others held their peace. "What sayest thou, Peter? He said, 'thou canst not,' and thou sayest, 'I can'? Therefore thou shalt know from this temptation that thy love is nothing without the presence of the impulse from above." Whence it is clear that in care for him He allowed even that fall. He desired indeed to teach him even by the first words, but when he continued in his vehemence, He did not indeed throw or force him into the denial, but left him alone, that he might learn his own weakness.
Christ had said that He must be betrayed; Peter replied, "Be it far from Thee, Lord; this shall not happen unto Thee." He was rebuked, but not instructed. On the contrary, when Christ desired to wash his feet, he said, "Thou shall never wash my feet." Again, when he hears, "Thou canst not follow Me now," he saith, "Though all deny Thee, I will not deny Thee." Since then it was likely that he would be lifted up to folly by his practice of contradiction, Jesus next teacheth him not to oppose Him. This too Luke implies, when he telleth us that Christ said, "And I have prayed for thee, that thy faith fail not"; that is, "that thou be not finally lost." In every way teaching him humility, and proving that human nature by itself is nothing.
But, since great love made him apt for contradiction, He now sobereth him, that he might not in after times be subject to this, when he should have received the stewardship of the world, but remembering what he had suffered, might know himself. And look at the violence of his fall; it did not happen to him once or twice, but he was so beside himself, that in a short time thrice did he utter the words of denial, that he might learn that he did not so love as he was loved. And yet, to one who had so fallen He saith again, "Lovest thou Me more than these?" So that the denial was caused not by the cooling of his love, but from his having been stripped of aid from above. He accepteth then Peter's love, but cutteth off the spirit of contradiction engendered by it. "For if thou lovest, thou oughtest to obey Him who is beloved."
"I will lay down my life for Thee." For since he had heard, "Greater love than this hath no man," he straightway sprang forward, insatiably eager and desirous to reach even to the highest pitch of virtue. But Christ, to show that it belonged to Himself alone to promise these things with authority, saith, "Before the cock crow." That is, "now"; there was but a little interval. He spake when it was late at night, and the first and second watch was past.
Peter had earlier answered the Lord out of a kind of proud self-assurance when he had told him, “I will lay down my life for you.” He had not yet received the strength to carry out that promise. Now, in order to be able to do so, he is already filled with charity. That is why he is asked, “Do you love me?” And he answers “I do,” because it is only charity that can carry it out. So how do things stand, Peter? Dying is what you were afraid of. He is alive and talking to you, the one you saw dead. Do not be afraid of death anymore. It has been conquered in him whose death you dreaded. He hung on the cross, he was fixed there with nails, he gave up the spirit, he was struck with a lance, laid in the tomb. That is what you were afraid of when you denied him, afraid you would suffer this. And by fearing death you denied life. Understand the truth now: when you were afraid of dying, that is when you died.
Peter promised he would die for him, and he was not even able to die with him. He had staked more, you see, than his credit could stand. He had promised more than he could fulfill, because it was in fact unfitting that he should do what he had promised. “I will lay down my life,” he said, “for you.” But that is what the Lord was going to do for the servant, not the servant for the Lord. So as he had staked more than he was worth, he was then loving in an inverted sort of way; that is why he was afraid and denied Christ. Later on, though, the Lord, after he has risen, teaches Peter how to love. While he was loving in the wrong way, he collapsed under the weight of Christ’s passion. But when he was loving in the right way, Christ promises him a passion of his own.
The blessed Peter, as we have just heard, is ordered to follow. And yet he had originally been thinking of going ahead when he said to the Lord, “I will lay down my life for you.” He was so sure of himself that he was unaware of his fear. He wanted to go ahead of the one he should be following. It was a good thing he was eager to do, but he did not keep to the right order.
But what does he say to this? "Why cannot I follow Thee now? I will lay down my life for Thy sake." He saw what was the kind of desire in his mind; but what the measure of his strength, he saw not. The weak man boasted of his willingness, but the Physician had an eye on the state of his health; the one promised, the Other foreknew: the ignorant was bold; He that foreknew all, condescended to teach. How much had Peter taken upon himself, by looking only at what he wished, and having no knowledge of what he was able! How much had he taken upon himself, that, when the Lord had come to lay down His life for His friends, and so for him also, he should have the assurance to offer to do the same for the Lord; and while as yet Christ's life was not laid down for himself, he should promise to lay down his own life for Christ!
What is there, he means, that prevents or that can keep him back from following His Master, now that his deliberate aim is to die for Christ's sake, reckoning this as his proudest boast? For the utmost of all danger, and the extremest violence of the implacable enmity of persecutors, have no effect beyond the range of the flesh; for with the flesh alone has death to deal: and he that is ready and fully prepared even for this extreme, would not easily be hindered from his purpose, or give up his intense conviction as to the duty of following to the end. The zeal of Peter was most ardent, and the extent of his promise excessive; yet one might see that the power latent in him was not inconsiderable, or rather the issue of the events themselves would convince one of this. One point however must be considered. Our Saviour Christ, speaking now in one way and now in another of His ascension into heaven, says that Peter will not follow Him now, but will follow Him hereafter; as soon, namely, as his apostolate is fulfilled, and when the fit season has come to summon the bodies of the saints to the city above: whereas Peter himself protests that he is now ready even to risk his life, going as it were by a different way, and not coming by a direct course to the meaning of the words. And I think his language must imply this: failing as yet to attach to what has been spoken by Christ its exact signification, he believes that the Lord intends possibly to pass over to some of the wilder villages in Judaea, or even to visit foreign peoples, who will, after carefully listening, so violently dissent from the words which He will be likely to speak, that the daring plots of the Pharisees will seem feeble compared with the base designs of the other Jews, and the madness inherent in them will be shown to be of the very mildest type. For this reason he declares that he will suffer nothing to interfere with his following Christ: he does not absolutely promise to die, but says that if the need should arise he will not shrink from death. Now there is a passage exactly similar to this in the previous part of this book, and I will proceed to tell you where it occurs.
At one time Christ was sojourning among the Galilaeans to avoid the fury of the Jews, their ungovernable temper, and their unbridled insolence in speech; and great was the wonder excited in those quarters by His marvellous deeds. But when the brother of Mary and Martha had died, I mean of course Lazarus, He as God knew of it, and forthwith said to His disciples: Our friend Lazarus is fallen asleep, but I go that I may awake him out of sleep. Hereupon the disciples affectionately reply: The Jews were but now seeking to stone Thee; and goest Thou thither again? And when Christ is on the point of starting, and urgently tells them that He must certainly return to the country of the Jews, Thomas, who is called Didymus, said unto his fellow-disciples, Let us also go, that we may die with Him. I believe that Peter's object in speaking is pregnant with some similar idea. For he thinks, perhaps, as I said just now, that Jesus is on the eve of departing to preach somewhere else among people at whose hands He will be exposed to danger. Therefore he himself also, in his uncontrollable affection for Christ, declares that his zeal now to defend his Master will be invincible and irresistible, meaning that there is nothing left in the world that is strong enough to check his devotion, now that he has convinced himself that he must follow Christ, seeing that he is ready and willing even to die in his Master's cause.
But Peter is so irrepressible in his eagerness that he even contradicts Christ. He is not satisfied with having received the good hope of following Christ later, but insists on his own way and self-confidently says: "Why can I not follow You now? I will lay down my life for You."
See what power desire has! Peter had heard the Lord say that "greater love has no one than this, that someone lay down his life for his friends" (John 15:13); therefore he himself strives for this degree and desires to attain the very highest love, which is why he promises to lay down his life for the Lord.
