Deo. Unus enim Deus, et unus mediator Dei et hominum homo Christus Jesus (I Tim. II, 5). Qui negat hominem Christum, non justificatur; quia sicut per inobedientiam unius hominis, peccatores constituti sunt multi; ita et per obedientiam unius hominis, justi constituentur multi (Rom. V, 19). Qui negat hominem Christum, non resurget in resurrectionem vitae; quia per hominem mors, et per hominem resurrectio mortuorum: sicut enim in Adam omnes moriuntur, ita et in Christo omnes vivificabuntur (I Cor. XV, 21 et 22). Per quid autem caput est Ecclesiae, nisi per hominem, quod Verbum caro factum est? id est, Dei Patris Unigenitus Deus homo factus est. Quomodo est igitur in corpore Christi, qui negat hominem Christum? Qui enim caput negat, quomodo est membrum? Sed quid multis immorer, cum ipse Dominus abstulerit omnes humanae argumentationis ambages? Non enim ait, Non cantabit gallus donec hominem neges; aut, sicut loqui familiariore cum hominibus dignatione consuevit, Non cantabit gallus donec Filium hominis ter neges: sed ait, donec me ter neges. Quid est, me, nisi quod erat? et quid nisi Christus erat? Quidquid ergo ejus negavit, ipsum negavit, Christum negavit, Dominum Deum suum negavit Quia et ille condiscipulus ejus Thomas, quando exclamavit, Dominus meus et Deus meus, non Verbum, sed carnem tetigit; non incorpoream Dei naturam, sed hominis corpus curiosis manibus contrectavit (Joan. XX, 27, 28). Hominem itaque tetigit, et tamen Deum cognovit. Si ergo quod iste tetigit, hoc Petrus negavit; quod iste exclamavit, hoc Petrus offendit. Non cantabit gallus, donec ter me neges. Dicas licet, Nescio hominem; dicas licet, Homo, nescio quid dicis; dicas licet, Non sum ex discipulis ejus (Matth. XXVI, 34, 69-74, et Luc. XXII, 55-60): me negabis. Si, quod dubitare nefas est, Christus hoc dixit, verumque praedixit, procul dubio Petrus Christum negavit. Non accusemus Christum cum defendimus Petrum. Peccatum agnoscat infirmitas; nam mendacium non habet veritas. Agnovit quippe peccatum suum infirmitas Petri, prorsus agnovit; et quantum mali Christum negando commiserit, plorando monstravit. Ipse suos redarguit defensores, et unde eos convincat, producit lacrymas testes. Neque nos cum ista dicimus, primum Apostolorum accusare delectat: sed hunc intuendo admoneri nos oportet, ne homo quisquam de humanis viribus fidat. Nam quid aliud pertinuit ad doctorem Salvatoremque nostrum, nisi ut nobis nequaquam de se quemquam praesumere debere, in ipso primo Apostolorum demonstraret exemplo? In anima itaque Petri contigit quod offerebat in corpore. Non tamen pro Domino, ut temere praesumebat, praecessit, sed aliter quam putabat. Namque ante mortem et resurrectionem Domini, et mortuus est negando, et revixit plorando: sed mortuus est, quia superbe ipse praesumpsit; revixit autem, quia benigne ille respexit.
to God. For there is one God, and one mediator of God and men, the man Christ Jesus (1 Tim. 2:5). Whoever denies the man Christ is not justified; because just as through the disobedience of one man many were made sinners, so also through the obedience of one man many will be made righteous (Rom. 5:19). Whoever denies the man Christ will not rise again to the resurrection of life; because through a man came death, and through a man the resurrection of the dead: for as in Adam all die, so also in Christ all will be made alive (1 Cor. 15:21–22). Through what, moreover, is He the head of the Church, except through the man, in that the Word was made flesh? that is, the Only-begotten God of God the Father was made man. How then is he in the body of Christ who denies the man Christ? For whoever denies the head, how is he a member? But why should I dwell on many things, when the Lord Himself has removed all the windings of human argumentation? For He does not say, The cock shall not crow until you deny the man; or, as He was accustomed to speak with a more familiar condescension towards men, The cock shall not crow until you deny the Son of man three times: but He says, until you deny me three times. What is "me", except what He was? and what was He but Christ? Whatever of Him, then, he denied, he denied Him Himself, he denied Christ, he denied his Lord God. For that fellow disciple of his too, Thomas, when he cried out, My Lord and my God, touched not the Word but the flesh; he handled with curious hands not the incorporeal nature of God, but the body of a man (John 20:27–28). It was a man, therefore, that he touched, and yet he recognized God. If, then, what this one touched, that Peter denied, what this one cried out, that Peter offended against. The cock shall not crow until you deny me three times. Though you say, I do not know the man; though you say, Man, I do not know what you are saying; though you say, I am not one of His disciples (Matt. 26:34, 69–74, and Luke 22:55–60): you will deny me. If, as it is impious to doubt, Christ said this and foretold truly, beyond doubt Peter denied Christ. Let us not accuse Christ when we defend Peter. Let weakness acknowledge sin; for truth has no falsehood. Indeed, the weakness of Peter acknowledged its sin, acknowledged it fully; and how much evil he had committed by denying Christ, he showed by weeping. He himself refutes his defenders, and, to convict them, he brings forward his tears as witnesses. Nor, when we say these things, does it delight us to accuse the first of the Apostles: but by looking upon him we ought to be admonished that no man should trust in human strength. For what else was the purpose of our Teacher and Saviour, except to show us, by the example of the very first of the Apostles, that no one ought by any means to presume on himself? In the soul of Peter, therefore, there happened what he was offering in the body. Yet he did not go ahead for the Lord, as he rashly presumed, but otherwise than he thought. For before the death and resurrection of the Lord he both died by denying and came to life again by weeping: but he died because he himself presumed proudly; he came to life again because that One looked upon him kindly.
