33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.
[AD 420] Jerome on Matthew 10:29-33
(Verse 29 onwards) Are not two sparrows sold for an assarion? Yet not one of them falls to the ground apart from your Father's will. But even the hairs of your head are all numbered. So do not fear; you are more valuable than many sparrows. Therefore, whoever confesses Me before men, I will also confess him before My Father who is in heaven. But whoever denies Me before men, I will also deny him before My Father who is in heaven. The Lord's discourse is attached to itself, and the following depend on the preceding. Wise reader, always beware of a superstitious understanding; so that you do not conform the Scriptures to your own senses, but join your senses to the Scriptures, and understand what follows. Above he had said: 'Do not fear those who kill the body, but cannot kill the soul'; now he speaks consequently, 'Are not two sparrows sold for a penny? And not one of them will fall to the ground without your Father.' And the meaning is this: If small and worthless animals do not perish without God as their author, and if there is providence in all things, and those things which are destined to perish do not perish without the will of God, then you who are eternal should not fear living without the providence of God. This meaning I have stated above: Look at the birds of the air, for they neither sow nor reap nor gather into barns; yet your heavenly Father feeds them. Are you not worth more than they? And afterwards: Consider the lilies of the field, how they grow, and so on. But if the grass of the field, which is here today and tomorrow is thrown into the oven, God clothes it, how much more will he clothe you, you of little faith! Some forcefully interpret the two sparrows as representing the soul and the body. Even five sparrows, according to Luke (Luke XII), which are sold for two pennies, are referred to the senses. But how that understanding is adapted to the whole body of the Gospel message is not of little difficulty. But even the hairs of your head are all counted. Therefore, do not be afraid; you are of more value than many sparrows. The deeper meaning of our previous explanation is expressed: that those who can kill the body should not be afraid, for they cannot kill the soul, and if even small animals do not fall without God's knowledge, how much more so for humans, who are supported by apostolic dignity! Moreover, when it is said that even the hairs of your head are all counted, it shows the immense providence of God towards humans and signifies His ineffable affection, that nothing about us escapes God, and even the smallest and most insignificant things do not elude His knowledge. They mock the ecclesiastical intelligence in this place, who deny the resurrection of the flesh, as if we were all saying that even the hairs that have been counted and cut by the barber will rise again, when the Savior did not say, 'But all the hairs on your head will be saved,' but 'They are counted.' Where there is number, the knowledge of number is demonstrated, not the preservation of the same number.

[AD 367] Hilary of Poitiers on Matthew 10:32-33
This He says in conclusion, because it behoves them after being confirmed by such teaching, to have a confident freedom in confessing God.

This teaches us, that in what measure we have borne witness to Him upon earth, in the same shall we have Him to bear witness to us in heaven before the face of God the Father.

[AD 407] John Chrysostom on Matthew 10:32-33
The Lord having banished that fear which haunted the minds of His disciples, adds further comfort in what follows, not only casting out fear, but by hope of greater rewards encouraging them to a free proclamation of the truth, saying, Every man who shall confess me before men, I also will confess him before my Father which is in heaven. And it is not properly shall confess me, but as it is in the Greek, shall confess in me, showing that it is not by your own strength but by grace from above, that you confess Him whom you do confess.

Here observe that the punishment is manifold more than the evil done, and the reward more than the good done. As much as to say, your deed was more abundant in confessing or denying Me here; so shall My deed to you-ward be more abundant in confessing or denying you there. Wherefore if you have done any good thing, and have not received retribution, be not troubled, for a manifold reward awaits you in the time to come. And if you have done any evil, and have not paid the punishment thereof, do not think that you have escaped, for punishment will overtake you, unless you are changed and become better.

He not only requires faith which is of the mind, but confession which is by the mouth, that He may exalt us higher, and raise us to a more open utterance, and a larger measure of love. For this is spoken not to the Apostles only, but to all; He gives strength not to them only, but to their disciples. And he that observes this precept will not only teach with free utterance, but will easily convince all; for the observance of this command drew many to the Apostles.

[AD 533] Remigius of Rheims on Matthew 10:32-33
Figuratively; Christ is the head, the Apostles the hairs, who are well said to be numbered, because the names of the saints are written in heaven.

Here is to be understood that confession of which the Apostle speaks, With the heart men believe unto justification, with the month confession is made unto salvation. (Rom. 10:10.) That none therefore might suppose that he could be saved without confession of the mouth, He says not only, He that shall confess me, but adds, before men; and again, He that shall deny me before men, him will I also deny before my Father which is in heaven.

And thus He will deny the man that hath denied Him, in that he shall not have access to the Father through Him, and shall be banished from seeing either the Son or the Father in their divine nature.

[AD 856] Rabanus Maurus on Matthew 10:32-33
It should be known that not even Pagans can deny the existence of God, but the infidels may deny that the Son as well as the Father is God. The Son confesses men before the Father, because by the Son we have access to the Father, and because the Son saith, Come, ye blessed of my Father. (Mat. 25:34.)

Or, He confesses Jesus who by that faith that worketh by love, obediently fulfils His commands; he denies Him who is disobedient.

[AD 220] Tertullian on Matthew 10:33
For why should you skulk withal, when you contaminate your own conscience by your neighbour's ignorance? If you are not unknown to be a Christian, you are tempted, and you act as if you were not a Christian against your neighbour's conscience; if, however, you shall be disguised withal, you are the slave of the temptation. At all events, whether in the latter or the former way, you are guilty of being "ashamed of God." But "whosoever shall be ashamed of Me in the presence of men, of him will I too be ashamed," says He, "in the presence of my Father who is in the heavens."

[AD 220] Tertullian on Matthew 10:33
God even in His own Scripture says: "The righteous shall flourish like the phoenix; " that is, shall flourish or revive, from death, from the grave-to teach you to believe that a bodily substance may be recovered even from the fire. Our Lord has declared that we are "better than many sparrows: " well, if not better than many a phoenix too, it were no great thing. But must men die once for all, while birds in Arabia are sure of a resurrection?

[AD 407] John Chrysostom on Matthew 10:33
God then is in no wise prompt to punish only, but also to confer benefits; and for this last more than for the first. But why has He put the reward once only, the punishment twice? He knows that this would be more apt to correct us. For this cause when He had said, Fear Him which is able to destroy both soul and body in hell, He says again, Him will I also deny. So does Paul also, continually making mention of hell.

Thus we see that He, having by all ways trained on His scholar (both by opening Heaven to him, and by setting before him that fearful judgment-seat, and by pointing to the amphitheatre of angels, and how in the midst of them the crowns shall be proclaimed, which thing would thenceforth prepare the way for the word of godliness to be very easily received); in what follows, lest they grow timid and the word be hindered, He bids them be prepared even for slaughter itself; to make them aware that such as continue in their error, will have to suffer (among other things) for plotting against them.

Let us therefore despise death, although the time be not come that requires it of us; for indeed it will translate us to a far better life. But the body decays. Why, on this account most especially we ought to rejoice, because death decays, and mortality perishes, not the substance of the body. For neither, should you see a statue being cast, would you call the process destruction, but an improved formation. Just so do thou reason also concerning the body, and do not bewail. Then it were right to bewail, had it remained in its chastisement.

But, says one, this ought to take place without the decay of our bodies; they should continue entire. And what would this have advantaged either the living or the departed? How long are you lovers of the body? How long are you rivetted to the earth and gaping after shadows? Why, what good would this have done? Or rather, what harm would it not have done? For did our bodies not decay, in the first place the greatest of all evils, pride, would have continued with many. For if even while this is going on, and worms gushing out, many have earnestly sought to be gods; what would not have been the result did the body continue?

In the second place, it would not be believed to be of earth; for if, its end witnessing this, some yet doubt; what would they not have suspected if they did not see this? Thirdly, the bodies would have been excessively loved; and most men would have become more carnal and gross; and if even now some cleave to men's tombs and coffins, after that themselves have perished, what would they not have done, if they had even their image preserved? Fourthly, they would not have earnestly desired the things to come. Fifthly, they that say the world is eternal, would have been more confirmed, and would have denied God as Creator. Sixthly, they would not have known the excellence of the soul, and how great a thing is the presence of a soul in a body. Seventhly, many of them that lose their relations would have left their cities, and have dwelt in the tombs, and have become frantic, conversing continually with their own dead. For if even now men form to themselves images, since they cannot keep the body (for neither is it possible, but whether they will or no it glides and hurries from them), and are rivetted to the planks of wood; what monstrous thing would they not then have devised? To my thinking, the generality would have even built temples for such bodies, and they that are skilled in such sorceries would have persuaded evil spirits to speak through them; since at least even now, they that venture on the arts of necromancy attempt many things more out of the way than these. And how many idolatries would not have arisen from hence? When men even after the dust and ashes, are yet eager in those practices.

God therefore, to take away all our extravagances, and to teach us to stand off from all earthly things, destroys the bodies before our eyes. For even he that is enamored of bodies, and is greatly affected at the sight of a beautiful damsel, if he will not learn by discourse the deformity of that substance, shall know it by the very sight. Yea, many of the like age with her whom he loves, and oftentimes also fairer, being dead, after the first or second day, have emitted an ill savor, and foul matter, and decay with worms. Imagine then what sort of beauty you love, and what sort of elegance has power so to disturb you. But if bodies did not decay, this would not be well known: but as evil spirits run unto men's graves, so also many of our lovers, continually sitting by the tombs, would have received evil spirits in their soul, and would quickly have perished in this grievous madness.

But as it is, together with all other things this also comforts the soul, that the form is not seen: it brings men to forgetfulness of their affliction. Indeed, if this were not so, there would be no tombs at all, but you would see our cities having corpses instead of statues, each man desiring to look upon his own dead. And much confusion would arise hence, and none of the ordinary sort would attend to his soul, nor would give room to the doctrine of immortality to enter in: and many other things too, more shocking than these, would have resulted, which even to speak of were unseemly. Wherefore it decays presently, that you might see unveiled the beauty of the soul. For if she be the procurer of all that beauty and life, much more excellent must she herself be. And if she preserve that which is so deformed and unsightly, much more herself.

For it is not the body wherein the beauty lies, but the expression, and the bloom which is shed over its substance by the soul. Now then, I bid you love that which makes the body also to appear such as it is. And why speak I of death? Nay even in life itself, I would have you mark how all is hers that is beautiful. For whether she be pleased, she showers roses over the cheeks; or whether she be pained, she takes that beauty, and involves it all in a dark robe. And if she be continually in mirth, the body improves in condition; if in grief, she renders the same thinner and weaker than a spider's web; if in wrath, she has made it again abominable and foul; if she show the eye calm, great is the beauty that she bestows; if she express envy, very pale and livid is the hue she sheds over us; if love, abundant the gracefulness she at once confers. Thus in fact many women, not being beautiful in feature, have derived much grace from the soul; others again of brilliant bloom, by having an ungracious soul, have marred their beauty. Consider how a face that is pale grows red, and by the variation of color produces great delight, when there is need of shame and blushing. As, on the other hand, if it be shameless, it makes the countenance more unpleasing than any monster.

For nothing is fairer, nothing sweeter than a beauteous soul. For while as to bodies, the longing is with pain, in the case of souls the pleasure is pure and calm. Why then let go the king, and be wild about the herald? Why leave the philosopher, and gape after his interpreter? Have you seen a beautiful eye? Acquaint yourself with that which is within; and if that be not beautiful, despise this likewise. For surely, did you see an ill-favored woman wearing a beautiful mask, she would make no impression on you: just as on the other hand, neither would you suffer one fair and beautiful to be disguised by the mask, but wouldest take it away, as choosing to see her beauty unveiled.

This then I bid you do in regard of the soul also, and acquaint yourself with it first; for this is clad with the body instead of a mask; wherefore also that abides such as it is; but the other, though it be mishapen, may quickly become beautiful. Though it have an eye that is unsightly, and harsh, and fierce, it may become beautiful, mild, calm, sweet-tempered, gentle.

This beauty therefore let us seek, this countenance let us adorn; that God also may have pleasure in our beauty, and impart to us of His everlasting blessings, by the grace and love towards man of our Lord Jesus Christ, to whom be glory and might forever and ever. Amen.
[AD 407] John Chrysostom on Matthew 10:33
The Son does not here speak soothing words but rather speaks of the consequences of denial. Note carefully: It is not by some power within yourself that you make your confession but by the help of grace from above. But if you deny me, the Son, he is saying, then I will deny you in the presence of the Father. Someone may then object: “How then am I to be blamed if God, forsaking me, denies me?” The answer is, Your being forsaken is the fault of you yourself, the forsaken person, not of God.“But why,” you object, “should I need to confess faith with my mouth if I confess faith in my mind?” No, we must confess with our mouths in order that we may be steadily trained to speak boldly. It is only through this more abundant love and determination that we will be raised on high.
In this way Jesus addresses himself to each one of us personally. He is not here addressing his original disciples only but every one of us who follows after his disciples in accord with their witness to him. One who learns this lesson will teach it in boldness to others, prepared to suffer all things easily and with a ready mind. This is why so many have come to have faith in the witness of the apostles to this Word.

[AD 1107] Theophylact of Ohrid on Matthew 10:33
. But whosoever shall deny Me before men, him will I also deny before My Father Who is in heaven. He exhorts them to bear witness even unto martyrdom. For belief only within one’s soul does not suffice; He desires also the belief confessed with the tongue. He did not say, "Whosoever shall confess Me," but "in Me" (ostis omologesei en emoi). that is, in My strength. For he who confesses does so aided by the grace which is from above. But as for him who denies, Christ did not say "in Me," but "whosoever shall deny Me," showing that he denies because he does not have the aid from above. Therefore everyone who confesses that Christ is God will find Christ giving confession of him to the Father, that he is a true servant. But those who deny will hear the words "I do not know you."
