John 13:38

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 said to thee and to those with thee, 'Thou canst not'; why art thou contentious? Knowest thou what a thing it is to contradict God? But since thou wilt not learn in this way that it is impossible that what I say should not come to pass, thou shalt learn it in the denial." And yet this appeared to thee to be much more incredible. For this thou did, not even understand, but of that thou hadst the knowledge in thy heart. Yet still that came to pass which was not even expected.

"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.

(Tr. lxvi. 1) Wilt thou do that for Me, which I have not done yet for thee? Canst thou go before, who canst not come after? Why presumest thou so? Hear what thou art: Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied Me thrice. Thou who promisest Me thy death, shall thrice deny thy life. Peter knew his great desire, his strength he knew not: he boasted of his will, while he was yet weak; but the Physician saw his weakness. (c. 2.). Some who perversely favour Peter, excuse him, and say that he did not deny Christ, because when asked by the servant maid, he said he did not know Him, as the other Evangelists witness more expressly. As if to deny the man Christ, was not to deny Christ; yea, that in Christ, which He was made for our sakes, that that which He made us, might not perish. By what is He the Head of the Church, but by His humanity? And how then is he in the body of Christ, who denies the man Christ? But why do I argue so long? Our Lord does not say, The cock shall not crow till thou deniest man, or the Son of man, but till thou deniest Me. What is Me, but that which He was? So then whatever Peter denied, he denied Christ: it is impious to doubt it. Christ said so, and Christ said true: beyond a doubt, Peter denied Christ. Let us not, to defend Peter, accuse Christ. The frailty of Peter himself, acknowledged its sin, when he witnessed by his tears the evil he had done in denying Christ. Nor do we say this, because we have pleasure in blaming the first of the Apostles; but that we may take warning from him, not to be confident of our own strength. (Tr. lxvi. 2) That took place in the soul of Peter, which he offered in the body; though differently from what he meant. For before the death and resurrection of our Lord, he both died by his denial, and lived again by his tears. (de Con. Evang. iii. c. 2. [5.]) This speech, The cock shall not crow, occurs in all the Evangelists, but not at the same time in all. Matthew and Mark introduce it after they have left the house, in which they were eating; Luke and John before. We may suppose either that the two former are recurring to what had passed, or the two latter anticipating what is coming. Or the great difference not only of the words, but of the subjects which precede the speech, and which excite Peter to the presumption of offering to die, for or with our Lord, may lead us to conclude that he made this offer three times, and that our Lord three times replied, Before the cock crow, thou shalt deny Me thrice.

"Jesus" therefore "answered him, Wilt thou lay down thy life for my sake?" Wilt thou do for me what I have not yet done for thee? "Wilt thou lay down thy life for my sake?" Canst thou go before, who art unable to follow? Why dost thou presume so far? what dost thou think of thyself? what dost thou imagine thyself to be? Hear what thou art: "Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied me thrice." See, that is how thou wilt speedily become manifest to thyself, who art now talking so loftily, and knowest not that thou art but a child. Thou promisest me thy death, and thou wilt deny me thy life. Thou, who now thinkest thyself able to die for me, learn to live first for thyself; for in fearing the death of thy flesh, thou wilt occasion the death of thy soul. Just as much as it is life to confess Christ, it is death to deny Him. Or was it that the Apostle Peter, as some with a perverse kind of favor strive to excuse him, did not deny Christ, because, when questioned by the maid, he replied that he did not know the man, as the other evangelists more expressly affirm? As if, indeed, he that denies the man Christ does not deny Christ; and so denies Him in respect of what He became on our account, that the nature He had given us might not be lost. Whoever, therefore, acknowledges Christ as God, and disowns Him as man, Christ died not for him; for as man it was that Christ died. He who disowns Christ as man, finds no reconciliation to God by the Mediator. For there is one God, and one Mediator between God and men, the man Christ Jesus. He that denies Christ as man is not justified: for as by the disobedience of one man, many were made sinners; so also by the obedience of one man shall many be made righteous. He that denies Christ as man, shall not rise again into the resurrection of life; for by man is death, and by man is also the resurrection of the dead: for as in Adam all die, even so in Christ shall all be made alive. And by what means is He the Head of the Church, but by His manhood, because the Word was made flesh, that is, God, the Only-begotten of God the Father, became man. And how then can one be in the body of Christ who denies the man Christ? Or how can one be a member who disowns the Head? But why linger over a multitude of reasons when the Lord Himself undoes all the windings of human argumentation? For He says not, The cock shall not crow till thou hast denied the man; or, as He was wont to speak in His more familiar condescension with men, The cock shall not crow till thou hast thrice denied the Son of man; but He says, "till thou hast denied me thrice." What is that "me," but just what He was, and what was He but Christ? Whatever of Him, therefore, he denied, he denied Himself, he denied the Christ, he denied the Lord his God. For Thomas also, his fellow-disciple, when he exclaimed, "My Lord and my God," did not handle the Word, but only His flesh; and laid not his inquisitive hands on the incorporeal nature of God, but on His human body. And so he touched the man, and yet recognized his God. If, then, what the latter touched, Peter denied; what the latter invoked, Peter offended. "The cock shall not crow till thou hast denied me thrice." Although thou say, "I know not the man;" although thou say, "Man, I know not what thou sayest;" although thou say, "I am not one of His disciples;" thou wilt be denying me. If, which it were sinful to doubt, Christ so spake, and foretold the truth, then doubtless Peter denied Christ. Let us not accuse Christ in defending Peter. Let infirmity acknowledge its sin; for there is no falsehood in the Truth. When Peter's infirmity acknowledged its sin, his acknowledgment was full; and the greatness of the evil he had committed in denying Christ, he showed by his tears. He himself reproves his defenders, and for their conviction, brings his tears forward as witnesses. Nor have we, on our part, in so speaking, any delight in accusing the first of the apostles
