21 And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
[AD 108] Ignatius of Antioch on Matthew 1:18-25
For what reason did God, deciding that the Savior should be born from a virgin, not choose a virgin who was not betrothed? Might it have been, then, an economy for her to conceive while having a betrothed, so that it might not appear as a disgrace upon her body for her to conceive? For it is rightly written in one of the letters of a certain martyr—I mean Ignatius, the second bishop of Antioch after the blessed Peter, who fought with beasts in Rome during the persecution—“and the virginity of Mary escaped the notice of the ruler of this age.” So, if it had not been for what seemed to be a marriage, it would not have escaped his notice, but the ruler of this age would have known that Mary, having never slept with a man, conceived, and thus the conception must be divine. The Savior wished through the entire economy to elude the devil, and indeed ordered the disciples not to make him manifest.

[AD 202] Irenaeus on Matthew 1:18-23
For the one and the same Spirit of God, who proclaimed by the prophets what and of what sort the advent of the Lord should be, did by these elders give a just interpretation of what had been truly prophesied; and He did Himself, by the apostles, announce that the fullness of the times of the adoption had arrived, that the kingdom of heaven had drawn near, and that He was dwelling within those that believe in Him who was born Emmanuel of the Virgin. To this effect they testify, [saying,] that before Joseph had come together with Mary, while she therefore remained in virginity, "she was found with child of the Holy Ghost;" [Matthew 1:18] and that the angel Gabriel said to her, "The Holy Ghost shall come upon you, and the power of the Highest shall overshadow you; therefore also that holy thing which shall be born of you shall be called the Son of God;" [Luke 1:35] and that the angel said to Joseph in a dream, "Now this was done, that it might be fulfilled which was spoken by Isaiah the prophet, Behold, a virgin shall be with child." [Matthew 1:23] But the elders have thus interpreted what Esaias said: "And the Lord, moreover, said to Ahaz, Ask for yourself a sign from the Lord your God out of the depth below, or from the height above. And Ahaz said, I will not ask, and I will not tempt the Lord. And he said, It is not a small thing for you to weary men; and how does the Lord weary them? Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son; and you shall call His name Emmanuel. Butter and honey shall He eat: before He knows or chooses out things that are evil, He shall exchange them for what is good; for before the child knows good or evil, He shall not consent to evil, that He may choose that which is good." [Isaiah 7:10-17] Carefully, then, has the Holy Ghost pointed out, by what has been said, His birth from a virgin, and His essence, that He is God (for the name Emmanuel indicates this). And He shows that He is a man, when He says, "Butter and honey shall He eat;" and in that He terms Him a child also, [in saying,] "before He knows good and evil;" for these are all the tokens of a human infant. But that He "will not consent to evil, that He may choose that which is good,"— this is proper to God; that by the fact, that He shall eat butter and honey, we should not understand that He is a mere man only, nor, on the other hand, from the name Emmanuel, should suspect Him to be God without flesh.

[AD 253] Origen of Alexandria on Matthew 1:18-25
For what reason did God, deciding that the Savior should be born from a virgin, not choose a virgin who was not betrothed? Might it have been, then, an economy for her to conceive while having a betrothed, so that it might not appear as a disgrace upon her body for her to conceive? For it is rightly written in one of the letters of a certain martyr—I mean Ignatius, the second bishop of Antioch after the blessed Peter, who fought with beasts in Rome during the persecution—“and the virginity of Mary escaped the notice of the ruler of this age.” So, if it had not been for what seemed to be a marriage, it would not have escaped his notice, but the ruler of this age would have known that Mary, having never slept with a man, conceived, and thus the conception must be divine. The Savior wished through the entire economy to elude the devil, and indeed ordered the disciples not to make him manifest. But even when he was tempted by the devil, nowhere did he openly declare that he is the Son of God, but merely said: it is not necessary for me to worship you, it is not necessary for me to make stones into bread, it is not necessary for me to throw myself down from above. Also, the Apostle says that the economy of the passion was done in forgetfulness of the opposing power: “which none of the rulers of this age understood; for if they had, they would not have crucified the Lord of glory.” If it was not hidden from the demon—for it said: “We know who you are, the Son of God”—see, the lesser in evil knew the Savior, but the greater in evil was hindered by the magnitude of his wickedness from beholding him.

[AD 1546] Martin Luther on Matthew 1:18-25
Now this refutes also the false interpretation which some have drawn from the words of Matthew, where he says, "Before they came together she was found to be with child." They interpret this as though the evangelist meant to say, "Later she came together with Joseph like any other wife and lay with him, but before this occurred she was with child apart from Joseph," etc. Again, when he says, "And Joseph knew her not until she brought forth her first-born son" [Matt. 1:25], they interpret it as though the evangelist meant to say that he knew her, but not before she had brought forth her first-born son. This was the view of Helvidius which was refuted by Jerome.

Such carnal interpretations miss the meaning and purpose of the evangelist. As we have said, the evangelist, like the prophet Isaiah, wishes to set before our eyes this mighty wonder, and point out what an unheard-of thing it is for a maiden to be with child before her husband brings her home and lies with her; and further, that he does not know her carnally until she first has a son, which she should have had after first having been known by him. Thus, the words of the evangelist do not refer to anything that occurred after the birth, but only to what took place before it. For the prophet and the evangelist, and St. Paul as well, do not treat of this virgin beyond the point where they have from her that fruit for whose sake she is a virgin and everything else. After the child is born they dismiss the mother and speak not about her, what became of her, but only about her offspring. Therefore, one cannot from these words [Matt. 1:18, 25] conclude that Mary, after the birth of Christ, became a wife in the usual sense; it is therefore neither to be asserted nor believed. All the words are merely indicative of the marvelous fact that she was with child and gave birth before she had lain with a man.

The form of expression used by Matthew is the common idiom, as if I were to say, "Pharaoh believed not Moses, until he was drowned in the Red Sea." Here it does not follow that Pharaoh believed later, after he had drowned; on the contrary, it means that he never did believe. Similarly when Matthew [1:25] says that Joseph did not know Mary carnally until she had brought forth her son, it does not follow that he knew her subsequently; on the contrary, it means that he never did know her. Again, the Red Sea overwhelmed Pharaoh before he got across. Here too it does not follow that Pharaoh got across later, after the Red Sea had overwhelmed him, but rather that he did not get across at all. In like manner, when Matthew [1:18] says, "She was found to be with child before they came together," it does not follow that Mary subsequently lay with Joseph, but rather that she did not lie with him.

Elsewhere in Scripture the same manner of speech is employed. Psalm 110 [:1] reads, "God says to my Lord: 'Sit at my right hand, till I make your enemies your footstool.'" Here it does not follow that Christ does not continue to sit there after his enemies are placed beneath his feet. Again, in Genesis 28 [:15], "I will not leave you until I have done all that of which I have spoken to you." Here God did not leave him after the fulfillment had taken place. Again, in Isaiah 42 [:4], "He shall not be sad, nor troublesome, till he has established justice in the earth." There are many more similar expression, so that this babble of Helvidius is without justification; in addition, he has neither noticed nor paid any attention to either Scripture or the common idiom.

[AD 1963] CS Lewis on Matthew 1:18-25
There is an activity of God displayed throughout creation, a wholesale activity let us say which men refuse to recognize. The miracles done by God incarnate, living as a man in Palestine, perform the very same things as this wholesale activity, but at a different speed and on a smaller scale. One of their chief purposes is that men, having seen a thing done by personal power on the small scale, may recognize, when they see the same thing done on the large scale, that the power behind it is also personal – is indeed the very same person who lived among us two thousand years ago. The miracles in fact are a retelling in small letters of the very same story which is written across the whole world in letters too large for some of us to see...

I can understand the man who denies the miraculous altogether; but what is one to make of the people who admit some miracles but deny the Virgin Birth? Is it that for all their lip service to the laws of Nature there is only one law of Nature that they really believe? Or is it that they see in this miracle a slur upon sexual intercourse which is rapidly becoming the one thing venerated in a world without veneration? No miracle is in fact more significant. What happens in ordinary generation? What is a father’s function in the act of begetting? A microscopic particle of matter from his body fertilizes the female: and with that microscopic particle passes, it may be, the color of his hair and his great grandfather’s hanging lip, and the human form in all its complexity of bones, liver, sinews, heart, and limbs, and pre-human form which the embryo will recapitulate in the womb. Behind every spermatozoon lies the whole history of the universe: locked within it is no small part of the world’s future. That is God’s normal way of making a man – a process that takes centuries, beginning with the creation of matter itself, and narrowing to one second and one particle at the moment of begetting. And once again men will mistake the sense impressions which this creative act throws off for the act itself or else refer it to some infinite being such as Genius. Once, therefore, God does it directly, instantaneously; without a spermatozoon, without the millenniums of organic history behind the spermatozoon. There was of course another reason. This time He was creating not simply a man, but the man who was to be Himself: the only true Man. The process which leads to the spermatozoon has carried down with it through the centuries much undesirable silt; the life which reaches us by that normal route is tainted. To avoid that taint, to give humanity a fresh start, he once short-circuited the process. There is a vulgar anti-God paper which some anonymous donor sends me every week. In it recently I saw the taunt that we Christians believe in a God who committed adultery with the wife of a Jewish carpenter. The answer to that is that if you describe the action of God in fertilizing Mary as “adultery” then, in that sense, God would have committed adultery with every woman who ever had a baby. For what He did once without a human father, He does always even when He uses a human father as His instrument. For the human father in ordinary generation is only a carrier, sometimes an unwilling carrier, always the last in a long line of carriers, of life that comes from the supreme life. Thus the filth that our poor, muddled, sincere, resentful enemies fling at the Holy One, either does not stick, or, sticking, turns into glory.


[AD 165] Justin Martyr on Matthew 1:21-23
And hear again how Isaiah in express words foretold that He should be born of a virgin; for he spoke thus: "Behold, a virgin shall conceive, and bring forth a son, and they shall say for His name, 'God with us.'" [Isaiah 7:14] For things which were incredible and seemed impossible with men, these God predicted by the Spirit of prophecy as about to come to pass, in order that, when they came to pass, there might be no unbelief, but faith, because of their prediction. But lest some, not understanding the prophecy now cited, should charge us with the very things we have been laying to the charge of the poets who say that Jupiter went in to women through lust, let us try to explain the words. This, then, "Behold, a virgin shall conceive," signifies that a virgin should conceive without intercourse. For if she had had intercourse with any one whatever, she was no longer a virgin; but the power of God having come upon the virgin, overshadowed her, and caused her while yet a virgin to conceive. And the angel of God who was sent to the same virgin at that time brought her good news, saying, "Behold, you shall conceive of the Holy Ghost, and shall bear a Son, and He shall be called the Son of the Highest, and you shall call His name Jesus; for He shall save His people from their sins," [Luke 1:32; Matthew 1:21] — as they who have recorded all that concerns our Saviour Jesus Christ have taught, whom we believed, since by Isaiah also, whom we have now adduced, the Spirit of prophecy declared that He should be born as we intimated before. It is wrong, therefore, to understand the Spirit and the power of God as anything else than the Word, who is also the first-born of God, as the foresaid prophet Moses declared; and it was this which, when it came upon the virgin and overshadowed her, caused her to conceive, not by intercourse, but by power. And the name Jesus in the Hebrew language means Σωτήρ (Saviour) in the Greek tongue. Wherefore, too, the angel said to the virgin, "You shall call His name Jesus, for He shall save His people from their sins." And that the prophets are inspired by no other than the Divine Word, even you, as I fancy, will grant.

[AD 220] Tertullian on Matthew 1:21
My present discussion is, how the evil spirit could have known that He was called by such a name, when there had never at any time been uttered about Him a single prophecy by a god who was unknown, and up to that time silent, of whom it was not possible for Him to be attested as "the Holy One," as (of a god) unknown even to his own Creator. What similar event could he then have published of a new deity, whereby he might betoken for "the holy one" of the rival god? Simply that he went into the synagogue, and did nothing even in word against the Creator? As therefore he could not by any means acknowledge him, whom he was ignorant of, to be Jesus and the Holy One of God; so did he acknowledge Him whom he knew (to be both). For he remembered how that the prophet had prophesied of "the Holy One" of God, and how that God's name of "Jesus" was in the son of Nun. These facts he had also received from the angel, according to our Gospel: "Wherefore that which shall be born of thee shall be called the Holy One, the Son of God; " and, "Thou shalt call his name Jesus."

[AD 407] John Chrysostom on Matthew 1:21
What the Angel thus told Joseph, was beyond human thought, and the law of nature, therefore he confirms his speech not only by revealing to him what was past, but also what was to come; She shall bring forth a Son.

Or, he left it unappropriated, to show that she bare Him to the whole world.

This further shows that this birth should be wonderful, because it is God that sends down His name from above by His Angel; and that not any name, but one which is a treasure of infinite good. Therefore also the Angel interprets it, suggesting good hope, and by this induces him to believe what was spoken. For we lean more easily to prosperous things, and yield our belief more readily to good fortune.

[AD 407] John Chrysostom on Matthew 1:21
Or rather, not by things past only, but like wise by things to come, he wins him over. And she shall bring forth, says he, a Son, and you shall call His name Jesus. Matthew 1:21 For do not thou, because He is of the Holy Ghost, imagine that you are an alien to the ministry of this dispensation. Since although in the birth you have no part, but the Virgin abode untouched, nevertheless, what pertains to a father, not injuring the honor of virginity, that do I give you, to set a Name on that which is born: for you shall call Him. For though the offspring be not yours, yet shall you exhibit a father's care towards Him. Wherefore I do straightway, even from the giving of the name, connect you with Him that is born.
Then lest on the other hand any one should from this suspect him to be the father, hear what follows, with what exact care he states it. She shall bring forth, he says, a Son: he does not say, bring forth to you, but merely she shall bring forth, putting it indefinitely: since not to him did she bring forth, but to the whole world.

13. For this cause too the angel came bringing His name from Heaven, hereby again intimating that this is a wondrous birth: it being God Himself who sends the name from above by the angel to Joseph. For neither was this without an object, but a treasure of ten thousand blessings. Wherefore the angel also interprets it, and suggests good hopes, in this way again leading him to belief. For to these things we are wont to be more inclined, and therefore are also fonder of believing them.

So having established his faith by all, by the past things, by the future, by the present, by the honor given to himself, he brings in the prophet also in good time, to give his suffrage in support of all these. But before introducing him, he proclaims beforehand the good things which were to befall the world through Him. And what are these? Sins removed and done away. For He shall save His people from their sins.

Here again the thing is signified to be beyond all expectation. For not from visible wars, neither from barbarians, but what was far greater than these, from sins, he declares the glad tidings of deliverance; a work which had never been possible to any one before.

But wherefore, one may ask, did he say, His people, and not add the Gentiles also? That he might not startle the hearer yet a while. For to him that listens with understanding he darkly signified the Gentiles too. For His people are not the Jews only, but also all that draw near and receive the knowledge that is from Him.

And mark how he has by the way discovered to us also His dignity, by calling the Jewish nation His people. For this is the word of one implying nought else, but that He who is born is God's child, and that the King of those on high is the subject of his discourse. As neither does forgiving sins belong to any other power, but only to that single essence.

14. Forasmuch then as we have partaken of so great a gift, let us do everything not to dishonor such a benefit. For if even before this honor, what was done was worthy of punishment, much more now, after this unspeakable benefit. And this I say not now for no cause, but because I see many after their baptism living more carelessly than the uninitiated, and having nothing peculiar to distinguish them in their way of life. It is, you see, for this cause, that neither in the market nor in the Church is it possible to know quickly who is a believer and who an unbeliever; unless one be present at the time of the mysteries, and see the one sort put out, the others remaining within. Whereas they ought to be distinguished not by their place, but by their way of life. For as men's outward dignities are naturally to be discovered by the outward signs with which they are invested, so ours ought to be discernible by the soul. That is, the believer ought to be manifest not by the gift only, but also by the new life. The believer ought to be the light and salt of the world. But when thou dost not give light even to yourself, neither bind up your own gangrene, what remains, whereby we are to know you? Because you have entered the holy waters? Nay, this to you becomes a store of punishment. For greatness of honor is, to them who do not choose to live worthy of the honor, an increase of vengeance. Yea, the believer ought to shine forth not only by what he has received from God, but also by what he himself has contributed; and should be discernible by everything, by his gait, by his look, by his garb, by his voice. And this I have said, not that display, but that the profit of beholders, may be the rule by which we frame ourselves.

15. But now, what things soever I might seek to recognize you by, I find you in all points distinguished by the contraries of the same. For whether by your place I would fain discern you, I see you spending your day in horse races, and theatres, and scenes of lawlessness, in the wicked assemblies in the market places, and in companies of depraved men; or by the fashion of your countenance, I see you continually laughing to excess, and dissolute as a grinning and abandoned harlot; or by your clothes, I see you in no better trim than the people on the stage; or by your followers, you are leading about parasites and flatterers; or by your words, I hear you say nothing wholesome, nothing necessary, nothing of moment to our life; or by your table, yet heavier from thence will the charge against you appear.

By what then, tell me, am I to recognize the believer in you, while all the things I have mentioned give the contrary sentence? And why do I say, the believer? Since I can not clearly make out whether you are a man. For when you are like an ass, kicking, and like a bull, wantoning, and like a horse neighing after women; when thou dost play the glutton like the bear, and pamper your flesh as the mule, and bear malice like the camel; also?

Further, if I were bidding you make another man gentle, not even so ought I to seem as one enjoining impossible things; however, you might then object that you have not the control of another's disposition, and that it does not altogether rest with you. But now it is your own wild beast, and a thing which absolutely depends on you. What plea then have you? Or what fair excuse will you be able to put forth, turning as you are a lion into a man, and regardless that you yourself art of a man becoming a lion; upon the beast bestowing what is above nature, but for yourself not even preserving what is natural? Yea, while the wild beasts are by your earnest endeavors advanced into our noble estate, you are by yourself cast down from the throne of the kingdom, and thrust out into their madness. Thus, imagine, if you will, your wrath to be a kind of wild beast, and as much zeal as others have displayed about lions, so much do thou in regard of yourself, and cause that way of taking things to become gentle and meek. Because this too has grievous teeth and talons, and if you tame it not, it will lay waste all things. For not even lion nor serpent has such power to rend the vitals as wrath, with its iron talons continually doing so. Since it mars, we see, not the body only, but the very health likewise of the soul is corrupted by it, devouring, rending, tearing to pieces all its strength, and making it useless for everything. For if a man nourishing worms in his entrails, shall not be able so much as to breathe, his inward parts all wasting away; how shall we, having so large a serpent eating up all within us (it is wrath I mean), how, I say, shall we be able to produce anything noble?

17. How then are we to be freed from this pest? If we can drink a potion that is able to kill the worms within us and the serpents. And of what nature, it will be asked, may this potion be, that has such power? The precious Blood of Christ, if it be received with full assurance, (for this will have power to extinguish every disease); and together with this the divine Scriptures carefully heard, and almsgiving added to our hearing; for by means of all these things we shall be enabled to mortify the affections that mar our soul. And then only shall we live; for now surely we are in no better state than the dead: forasmuch as it cannot be, that while those passions live, we should live too, but we must necessarily perish. And unless we first kill them here, they will be sure to kill us in the other life; or rather before that death they will exact of us, even here, the utmost penalty. Yes, for every such passion is both cruel and tyrannical and insatiable, and never ceases to devour us every day. For their teeth are the teeth of a lion, Joel 1:6 or rather even far more fierce. For the lion, as soon as ever he is satisfied, is wont to leave the carcass that has fallen in his way; but these passions neither are satisfied, nor do they leave the man whom they have seized, until they have set him near the devil. For so great is their power, that the very service which Paul showed forth to Christ, Romans 8:38 despising both hell and the kingdom for His sake, even this same do they require of them whom they have seized. For whether it be with the love of women, or of riches, or of glory, that any one is entangled, he laughs at hell thenceforth, and despises the kingdom, that he may work the will of these. Let us not then doubt Paul when he says that he so loved Christ. For when some are found so doing service to their passions, how should that other afterwards seem incredible? Yea, and this is the reason why our longing for Christ is feebler, because all our strength is consumed on this love, and we rob, and defraud, and are slaves to vainglory; than which what can be more worthless?

For though you should become infinitely conspicuous, you will be nothing better than the base: rather for this selfsame cause you will even be baser. For when they who are willing to give you glory, and make you illustrious, do for this very cause ridicule you, that you desire the glory which comes of them, how can such instances fail to turn the contrary way in regard of you. For indeed this thing is among those which attract censure. So that even as in the case of one desiring to commit adultery or fornication, should any one praise or flatter him, by this very act he becomes an accuser rather than a commender of the person indulging such desires: so with regard to him who is desirous of glory; when we all praise, it is accusation rather than praise which we bestow on those who wish to be made glorious.

18. Why then bring upon yourself that, from which the very opposite is wont to befall you. Yea, if you will be glorified, despise glory; so shall you be more illustrious than any. Why feel as Nebuchadnezzar felt? For he too set up an image, thinking from wood and from a senseless figure to procure to himself an increase of fame, and the living would fain appear more glorious by the help of that which has no life. Do you see the excess of his madness; how, thinking to do honor, he rather offered insult, to himself? For when it appears that he is relying rather on the lifeless thing, than on himself and the soul that lives in him, and when for this cause he advances the stock unto such high precedence, how can he be other than ridiculous, endeavoring as he does to adorn himself, not by his way of living, but by planks of wood? Just as if a man should think proper to give himself airs, because of the pavement of his house, and his beautiful staircase rather than because he is a man. Him do many too among us imitate now. For as he for his image, so some men claim to be admired for their clothes, others for their house; or for their mules and chariots, and for the columns in their house. For inasmuch as they have lost their being as men, they go about gathering to themselves from other quarters such glory as is full of exceeding ridicule.

But as to the noble and great servants of God, not by these means, but by such as best became them, even by such did they shine forth. For captives as they were, and slaves, and youths, and strangers, and stripped of all resources of their own, they proved at that time far more awful than he who was invested with all these things. And while Nebuchadnezzar found neither so great an image, nor satraps, nor captains of the host, nor endless legions, nor abundance of gold, nor other pomp, enough to meet his desire, and to show him great; to these, on the other hand, stripped of all this, their high self-restraint alone was sufficient, and showed him that wore the diadem and the purple, as much inferior in glory to those who had no such thing, as the sun is more glorious than a pearl. For they were led forth in the midst of the whole world, being at once youths, and captives, and slaves, and straightway on their appearance the king darted fire from his eyes, and captains, and deputies, and governors, and the whole amphitheatre of the devil, stood around; and a voice of pipes from all sides, and of trumpets, and of all music, borne up to Heaven, was sounding in their ears, and the furnace burned up to a boundless height, and the flame reached the very clouds, and all was full of terror and dismay. But none of these things dismayed them, but they laughed it all to scorn, as they would children mocking them, and exhibited their courage and meekness, and uttering a voice clearer than those trumpets, they said, Be it known unto you, O king. Daniel 3:18 For they did not wish to affront the king, no not so much as by a word, but to declare their religion only. For which cause, neither did they extend their speech to any great length, but set forth all briefly; For there is, say they, a God in Heaven, who is able to deliver us, Daniel 3:17 why do you show me the multitude? Why the furnace? Why the sharpened swords? Why the terrible guards? Our Lord is higher and more mighty than all these.

Then when they considered that it was possible that God might be willing even to permit them to be burnt; lest, if this should come to pass, they might seem to be speaking falsehoods; they add this also and say, If this happen not, be it known unto you, O king, that we serve not your gods. Daniel 3:18 For had they said, Sins are the cause of His not delivering us, should He fail to deliver, they would not have been believed. Wherefore in this place they are silent on that subject, though they speak of it in the furnace, again and again alleging their sins. But before the king they say no such thing; only, that though they were to be burnt, they would not give up their religion.

For it was not for rewards and recompenses that they did what they did, but out of love alone; and yet they were in captivity too, and in slavery, and had enjoyed no good thing. Yea, they had lost their country, and their freedom, and all their possessions. For tell me not of their honors in the king's courts, for holy and righteous as they were, they would have chosen ten thousand times rather to have been beggars at home, and to have been partakers of the blessings in the temple. For I had rather, it is said, be an outcast in the house of my God, than to dwell in the tents of sinners. And one day in your courts is better than thousands. They would have chosen then ten thousand times rather to be outcasts at home, than kings in Babylon. And this is manifest, from what they declare even in the furnace, grieving at their continuance in that country. For although themselves enjoyed great honors, yet seeing the calamities of the rest they were exceedingly vexed; and this kind of thing is most especially characteristic of saints, that no glory, nor honor, nor anything else should be more precious to them than their neighbor's welfare. See, for example, how even when they were in a furnace, they made their supplication for all the people. But we not even when at large bear our brethren in mind. And again, when they were inquiring about the dreams, Daniel 2:17-18 they were looking not to their own but the common good, for that they despised death they showed by many things afterwards. But everywhere they put themselves forward, as wishing to prevail with God by importunity. Next, as not accounting themselves either to be sufficient, they flee to the Fathers; but of themselves they said that they offer nothing more than a contrite spirit.

19. These men then let us also imitate. Because now too there is set up a golden image, even the tyranny of Mammon. But let us not give heed to the timbrels, nor to the flutes, nor to the harps, nor to the rest of the pomp of riches; yea, though we must needs fall into a furnace of poverty, let us choose it, rather than worship that idol, and there will be in the midst a moist whistling wind. Let us not then shudder at hearing of a furnace of poverty. For so too at that time they that fell into the furnace were shown the more glorious, but they that worshipped were destroyed. Only then all took place at once, but in this case some part will be accomplished here, some there, some both here and in the day that is to come. For they that have chosen poverty, in order that they might not worship mammon, will be more glorious both here and then, but they that have been rich unjustly here, shall then pay the utmost penalty.

From this furnace Lazarus too went forth, not less glorious than those children; but the rich man who was in the place of them that worshipped the image, was condemned to hell. For indeed what we have now mentioned was a type of this. Wherefore as in this instance they who fell into the furnace suffered no hurt, but they who sat without were laid hold of with great fierceness, so likewise shall it be then. The saints walking through the river of fire shall suffer no pain, nay they will even appear joyous; but they that have worshipped the image, shall see the fire rest upon them fiercer than any wild beast, and draw them in. So that if any one disbelieves hell, when he sees this furnace, let him from the things present believe things to come, and fear not the furnace of poverty, but the furnace of sin. For this is flame and torment, but that, dew and refreshment; and by this stands the devil, by that, angels wafting aside the flame.

20. These things let them hear that are rich, that are kindling the furnace of poverty. For though they shall not hurt those others, the dew coming to their aid; yet themselves they will render an easy prey to the flame, which they have kindled with their own hands.

Then, an angel went down with those children; now, let us go down with them that are in the furnace of poverty, and by almsdeeds let us make a dewy air, and waft the flame quite aside, that we may be partakers of their crowns also; that the flames of hell may likewise be scattered by the voice of Christ saying, You saw me an hungered, and fed me. Matthew 25:35 For that voice shall then be with us instead of a moist wind whistling through the midst of the flame. Let us then go down with almsgiving, unto the furnace of poverty; let us behold them that in self-restraint walk therein, and trample on the burning coals; let us behold the marvel, strange and beyond thought, a man singing praise in a furnace, a man giving thanks in fire, chained unto extreme poverty, yet offering much praise to Christ. Since they, who bear poverty with thankfulness, really become equal to those children. For no flame is so terrible as poverty, nor so apt to set us on fire. But those children were not set on fire; rather, on their giving thanks to the Lord, their bonds too were at once loosed. So likewise now, if when you have fallen into poverty, you are thankful, both the bonds are loosened, and the flame extinguished; or though it be not extinguished (what is much more marvellous), it becomes a fountain instead of a flame: which then likewise came to pass, and in the midst of a furnace they enjoyed a pure dew. For the fire indeed it quenched not, but the burning of those cast in it altogether hindered. This one may see in their case also who live by the rules of wisdom, for they, even in poverty, feel more secure than the rich.

Let us not therefore sit down without the furnace, feeling no pity towards the poor; lest the same befall us as then befell those executioners. For if you should go down to them, and take your stand with the children, the fire will no longer work you any harm; but if you should sit above and neglect them in the flame of their poverty, the flame will burn you up. Go down therefore into the fire, that you may not be burnt up by the fire; sit not down without the fire, lest the flame catch hold of you. For if it should find you among the poor, it will depart from you; but if alienated from them, it will run upon you quickly, and catch you. Do not therefore stand off from them that are cast in, but when the devil gives command to cast them that have not worshipped gold into the furnace of poverty, be not thou of them that cast others in, but of them that are cast in; that you may be of the number of the saved, and not of the burned. For indeed it is a most effectual dew, to be held in no subjection by desire of wealth, to be associate with poor persons. These are wealthier than all, who have trampled under foot the desire of riches. Forasmuch as those children too, by despising the king at that time, became more glorious than the king. And thou therefore, if you despise the things of the world, shall become more honorable than all the world; like those holy men, of whom the world was not worthy. Hebrews 11:38

In order then to become worthy of the things in Heaven, I bid you laugh to scorn things present. For in this way you shall both be more glorious here, and enjoy the good things to come, by the grace and love towards man of our Lord Jesus Christ; to whom be glory and might for ever and ever. Amen.
[AD 407] John Chrysostom on Matthew 1:21
It was as if the angel were saying to Joseph, “Do not imagine that, because he is conceived of the Holy Spirit, that you have no part in the ministry of this new dispensation. In the conception you had no part. You never touched the virgin. Nevertheless I am giving you what pertains to a father. I give you the honor of giving a name to the One who is to be born. For you, Joseph, shall name him. For though the offspring is not your own, yet you are called to exhibit a father’s care toward him. So on this occasion, at this moment of giving him a name, you stand in significant relation with the one who is born.” Then lest on the other hand anyone should, out of all this, suspect him to be the father, hear what follows and with what exact care the angel states it: “She shall bring forth a Son.” He does not say “bring forth to you” but merely “she shall bring forth,” putting it indefinitely, since it was not merely to him that she brought forth, but to the whole world.

[AD 420] Jerome on Matthew 1:21
Jesus is a Hebrew word, meaning Saviour. He points to the etymology of the name, saying, For He shall save His people from their sins.

[AD 420] Jerome on Matthew 1:21
(Verse 21.) And you shall call his name Jesus. For he will save his people from their sins. Jesus means 'Savior' in Hebrew. The evangelist noted the etymology of his name, saying: 'You shall call his name Jesus, for he will save his people.'

[AD 430] Augustine of Hippo on Matthew 1:21
(Enchir. 38.) But shall we therefore say that the Holy Spirit is the Father of the man Christ, that as God the Father begot the Word, so the Holy Spirit begot the man? This is such an absurdity, that the ears of the faithful cannot bear it.
How then do we say that Christ was born by the Holy Spirit, if the Holy Spirit did not beget Him? Did He create Him? For so far as He is man He was created, as the Apostle speaks; He was made of the seed of David according to the flesh. (Rom. 1:3.) For though God made the world, yet is it not right to say that it is the Son of God, or born by Him, but that it was made, or created, or formed by Him. But seeing that we confess Christ to have been born by the Holy Spirit, and of the Virgin Mary, how is He not the Son of the Holy Spirit, and is the Son of the Virgin? It does not follow, that whatever is born by any thing, is therefore to be called the son of that thing; for, not to say that of man is born in one sense a son, in another a hair, or vermin, or a worm, none of which are his son, certainly those that are born of water and the Spirit none would call sons of water; but sons of God their Father, and their Mother the Church. Thus Christ was born of the Holy Spirit, and yet is the Son of God the Father, not of the Holy Spirit.

[AD 450] Peter Chrysologus on Matthew 1:21
Let them approach to hear this, who ask, Who is He that Mary bare? He shall save His people; not any other man's people; from what? from their sins. That it is God that forgives sins, if you do not believe the Christians so affirming, believe the infidels, or the Jews who say, None can forgive sins but God only. (Luke 5:1.)

[AD 533] Remigius of Rheims on Matthew 1:21
He shows the same man to be the Saviour of the whole world, and the Author of our salvation. He saves indeed not the unbelieving, but His people; that is, He saves those that believe on Him, not so much from visible as from invisible enemies; that is, from their sins, not by fighting with arms, but by remitting their sins.

[AD 856] Rabanus Maurus on Matthew 1:21
Thou shalt call His name, he says, and not, "shalt give Him a name," for His name had been given from all eternity.

[AD 1107] Theophylact of Ohrid on Matthew 1:21
So that no one could ask, "How can I believe you that she has conceived of the Holy Spirit?" the angel speaks of the future, saying that she shall bear a son. "For if I tell the truth in this matter, it is clear that what I said concerning her conception of the Holy Spirit is also true." The angel did not say, "She shall bear you a son," but simply, "She shall bear a son." For Mary did not bring forth for Joseph’s sake, but for the whole world; nor did this grace concern him alone, but it was poured out on all.

"Thou shalt call," as though you were His father, and as the protector of the Virgin. For you must not think, Joseph, that because the conception is of the Holy Spirit that you can leave the Virgin helpless, but rather you will serve her in all things.

Here he interprets the name "Jesus," showing that it means "Saviour." The angel says that Jesus will save His people, not only the Jewish people, but also the Gentiles who are eager to believe and to become His people. From whom will He save them? Perhaps from enemies? No, but from their sins. Hence it is clear that it is God Who will be born, for it is the attribute of God alone to forgive sins.
[AD 1274] Pseudo-Chrysostom on Matthew 1:21
He said not, Shall bear thee a Son, as to Zacharias, Behold, Elisabeth thy wife shall bear thee a son. For the woman who conceives of her husband, bears the son to her husband, because he is more of him than of herself; but she who had not conceived of man, did not bear the Son to her husband, but to herself.

[AD 1274] Glossa Ordinaria on Matthew 1:21
(ap. Anselm.) That Joseph should not suppose that he was no longer needed in this wedlock, seeing the conception had taken place without his intervention, the Angel declares to him, that though there had been no need of him in the conception, yet there was need of his guardianship; for the Virgin should bear a Son, and then he would be necessary both to the Mother and her Son; to the Mother to screen her from disgrace, to the Son to bring Him up and to circumcise Him. The circumcision is meant when he says, And thou, shalt call His name Jesus; for it was usual to give the name in circumcision.
