John 3:16

In His address to Nicodemus He says: "So God loved the world, that He gave His only-begotten Son, that whosoever believeth in Him should not perish, but have everlasting life." And again: "For God sent not His Son into the world to condemn the world, but that the world through Him might be saved.

(vi. de Trin. c. 40) If it were only a creature given up for the sake of a creature, such a poor and insignificant loss were no great evidence of love. They must be precious things which prove our love, great things must evidence its greatness. God, in love to the world, gave His Son, not an adopted Son, but His own, even His Only Begotten. Here is proper Sonship, birth, truth: no creation, no adoption, no lie: here is the test of love and charity, that God sent His own and only begotten Son to save the world.

God, who loved the world, gave his only begotten Son as a manifest token of his love. If the evidence of his love is this, that he bestowed a creature on creatures, gave a worldly being on the world's behalf, granted one raised up from nothing for the redemption of objects equally raised up from nothing, such a cheap and petty sacrifice is a poor assurance of his favor toward us. Gifts of price are the evidence of affection: the greatness of the surrender is evidence of the greatness of the love. God, who loved the world, gave no adopted son but his own, his only begotten [Son]. Here is personal interest, true sonship, sincerity; not creation, or adoption, or pretence. Here is the proof of his love and affection, that he gave his own, his only begotten Son.

Abraham had many servants. Why did he [God] not tell him to offer up one of them as a sacrifice? It was only because his love would not be shown in a servant. His son was thus needed, so that through him Abraham's love would be revealed. God had servants like this, but he did not show his love through any of them for his creatures, but rather through his Son, so that through him his love toward us might be proclaimed.…From [the time of] Abraham, the symbols of the wood and of the lamb began to take shape. Isaac was a symbol of the lamb [caught] in the tree, and Jacob showed the wood that was life-giving for water. Thus wood was esteemed as worthy for him to hang upon it, because not a bone in him was broken. As for the earth, its fruits are stimulated by wood, and for the sea, its treasures are taken by means of wood. This is also the case for the body and the soul. Thus it [the wood of the cross] was carved by the fury of the savage crowd. It was like a mute person in its silence, but in its use it bore fruit exalting the status of human beings.

Let us praise the Son first of all, venerating the blood that expiated our sins. He lost nothing of his divinity when he saved me, when like a good physician he stooped to my festering wounds. He was a mortal man, but he was also God. He was of the race of David but Adam's creator. He who has no body clothed himself with flesh. He had a mother who, nonetheless, was a virgin. He who is without bounds bound himself with the cords of our humanity. He was victim and high priest—yet he was God. He offered up his blood and cleansed the whole world. He was lifted up on the cross, but it was sin that was nailed to it. He became as one among the dead, but he rose from the dead, raising to life also many who had died before him. On the one hand, there was the poverty of his humanity; on the other, the riches of his divinity. Do not let what is human in the Son permit you wrongfully to detract from what is divine. For the sake of the divine, hold in the greatest honor the humanity, which the immortal Son took on himself for love of you.

Having said, Even so must the Son of man be lifted up, alluding to His death; lest His hearer should be cast down by His words, forming some human notion of Him, and thinking of His death as an evil1, He corrects this by saying, that He who was given up to death was the Son of God, and that His death would be the source of life eternal; So God loved the world, that He gave His only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life; as if He said, Marvel not that I must be lifted up, that you may be saved: for so it seemeth good to the Father, who hath so loved you, that He hath given His Son to suffer for ungrateful and careless servants. The text, God so loved the world, shows intensity of love. For great indeed and infinite is the distance between the two. He who is without end, or beginning of existence, Infinite Greatness, loved those who were of earth and ashes, creatures laden with sins innumerable. And the act which springs from the love is equally indicative of its vastness. For God gave not a servant, or an Angel, or an Archangel, but His Son. Again, had He had many sons, and given one, this would have been a very great gift; but new He hath given His Only Begotten Son.

What He saith, is of this kind: Marvel not that I am to be lifted up that ye may be saved, for this seemeth good to the Father, and He hath so loved you as to give His Son for slaves, and ungrateful slaves. Yet a man would not do this even for a friend, nor readily even for a righteous man; as Paul has declared when he said, "Scarcely for a righteous man will one die." Now he spoke at greater length, as speaking to believers, but here Christ speaks concisely, because His discourse was directed to Nicodemus, but still in a more significant manner, for each word had much significance. For by the expression, "so loved," and that other, "God the world," He shows the great strength of His love. Large and infinite was the interval between the two. He, the immortal, who is without beginning, the Infinite Majesty, they but dust and ashes, full of ten thousand sins, who, ungrateful, have at all times offended Him; and these He "loved." Again, the words which He added after these are alike significant, when He saith, that "He gave His Only-begotten Son," not a servant, not an Angel, not an Archangel. And yet no one would show such anxiety for his own child, as God did for His ungrateful servants.

His Passion then He sets before him not very openly, but rather darkly; but the advantage of the Passion He adds in a clearer manner, saying, "That every one that believeth in Him should not perish, but have everlasting life." For when He had said, "must be lifted up," and alluded to death, lest the hearer should be made downcast by these words, forming some mere human opinions concerning Him, and supposing that His death was a ceasing to be, observe how He sets this right, by saying, that He that was given was "The Son of God," and the cause of life, of everlasting life. He who procured life for others by death, would not Himself be continually in death; for if they who believed on the Crucified perish not, much less doth He perish who is crucified. He who taketh away the destitution of others much more is He free from it; He who giveth life to others, much more to Himself doth He well forth life. Seest thou that everywhere there is need of faith? For He calls the Cross the fountain of life; which reason cannot easily allow, as the heathens now by their mocking testify. But faith which goes beyond the weakness of reasoning, may easily receive and retain it. And whence did God "so love the world"? From no other source but only from his goodness.

For He came down and died, and by that death delivered us from death: being slain by death, He slew death. And you know, brethren, that this death entered into the world through the devil's envy. "God made not death," saith the Scripture, "nor delights He in the destruction of the living; but He created all things to be." But what saith it here? "But by the devil's envy, death entered into the whole world." To the death offered for our entertainment by the devil, man would not come by constraint; for the devil had not the power of forcing, but only cunning to persuade. Hadst thou not consented, the devil had brought in nothing: thy own consenting, O man, led thee to death. Of the mortal are mortals born; from immortals we are become mortals. From Adam all men are mortal; but Jesus the Son of God, the Word of God, by which all things were made, the only Son equal with the Father, was made mortal: "for the Word was made flesh, and dwelt among us."

Unless the Father, you see, had handed over life, we would not have had life. And unless life itself had died, death would not have been slain. It is the Lord Christ himself, of course, that is life, about whom John the Evangelist says, "This is the true God and eternal life." It was he himself that through the prophet had also threatened death with death, saying, "I will be your death, O death; I will be your sting." This was as though he had said, "I will slay you by dying. I will swallow you up. I will take all your power away from you. I will rescue the captives you have held. You wanted to hold me, though innocent. It is right that you should lose those you had the power to hold."

He desireth to show openly herein, that He is God by Nature, since one must needs deem that He Who came forth from God the Father, is surely God also, not having the honour from without, as we have, but being in truth what He is believed to be. With exceeding skill does He say this, having joined therewith the love of God the Father to us, well and opportunely coming to discourse thereon. For He shames the unbelieving Nicodemus, yea rather, He shows that he is ungodly also. For the not coming readily to believe, when God teaches anything, what else is it, than laying upon the Truth a charge of falsehood? Besides this, in saying that He was given for the life of the world, He persuades him to consider seriously, of how great punishment they will be in danger, who from their mad folly, have made of no account so wondrous grace of God the Father. For God, says He, so loved the world that He gave His Only Begotten Son.

Let the Christ-opposing heretic again hear, and let him come forward and say, what is the greatness of the Love of God the Father, or how we should reasonably marvel at it. But he will say that the marvel of the love is seen, in His giving His Son for us, and that the Only Begotten. In order then that the great love of God the Father may remain and be preserved, let Him be held to be Son not a creature, I mean Son of the Essence of the Father, that is to say, Consubstantial with Him Who begat Him, and God verily and in truth. But if, according to thy speech, o thou, He possesseth not the being of the Essence of God the Father, He will also lose the being by Nature Son and God, and the wide-spread marvel of the Love of God will at length come to nought: for He gave a creature for creatures, and not truly His Son. Vainly too will the blessed Paul trouble us, saying, He that despised Moses' law died without mercy under two or three witnesses: of how much sorer punishment, suppose ye, shall he be thought worthy who hath trodden under foot the Son of God? For confessedly he that despised trampleth under foot, but not the Very Son, but a fellow servant of Moses, if indeed creature be always akin to creature, in respect at least of having been made, even if it surpass the glory of another, in the excellences of being greater or better. But the word of Paul is true; and a severer penalty shall he pay who hath trodden under foot the Son, not as though he were transgressing against a creature, or one of the fellow servants of Moses. Great then and above nature is the Love of the Father, Who for the life of the world gave His Own Son and Who is of Himself.

The sum of all is God, the Lord of all, who from love of his creatures has delivered his Son to death on the cross. For God so loved the world that he gave his only begotten Son for it. Not that he was unable to save us in another way, but in this way it was possible to show us his abundant love abundantly, namely, by bringing us near to him by the death of his Son. If he had anything more dear to him, he would have given it to us, in order that by it our race might be his. And out of his great love he did not even choose to urge our freedom by compulsion, though he was able to do so. But his aim was that we should come near to him by the love of our mind. And our Lord obeyed his Father out of love for us.

Note here, that the same which he before said of the Son of man, lifted up on the cross, he repeats of the only begotten Son of God: viz. That whosoever believeth in Him, &c. For the same our Maker and Redeemer, who was Son of God before the world was, was made at the end of the world the Son of man; so that He who by the power of His Godhead had created us to enjoy the happiness of an endless life, the same restored us to the life we have lost by taking our human frailty upon Him.

Our Redeemer and Maker, who was Son of God before the ages, became Son of man at the end of ages. Thus the one who, through the power of his divinity, had created us to enjoy the happiness of everlasting life, might himself restore us, through the weakness of our humanity, to recover the life we had lost.

Truly through the Son of God shall the world have life; for for no other cause came He into the world, except to save the world. God sent not His Son into the world to condemn the world, but that the world through Him might be saved.

(in loc.) As He said above, that the Son of man came down from heaven, not meaning that His flesh did come down from heaven, on account of the unity of person in Christ, attributing to man what belonged to God: so now conversely what belongs to man, he assigns to God the Word. The Son of God was impassible; but being one in respect of person with man, who was passible, the Son is said to be given up to death; inasmuch as He truly suffered, not in His own nature, but in His own flesh. From this death follows an exceeding great and incomprehensible benefit: viz. that whosoever believeth in Him should not perish, but have everlasting life. The Old Testament promised to those who obeyed it, length of days: the Gospel promises life eternal, and imperishable.

The love of God for the world is great and extended so far that He gave not an angel, not a prophet, but His Son, and moreover His Only-Begotten (1 John 4:9). If He had given even an angel, that deed would not have been small. Why? Because an angel is His faithful and obedient servant, while we are enemies and apostates. But now, when He gave His Son, what surpassing love He showed! Again, if He had many sons and gave one, even that would have been a very great thing. But now He gave His Only-Begotten. Can His goodness then be worthily praised?
The Arians say that the Son is called Only-begotten because He alone was produced and created by God, while everything else was then created by Him. The answer to them is simple. If He had been called Only-begotten without the word "Son," then your subtle invention would have had a basis. But now, since He is called both Only-begotten and Son, the word "Only-begotten" cannot be understood as you understand it, but rather that He alone was begotten of the Father.
Note, I ask you, that just as above He said that the Son of Man came down from heaven, not meaning that His flesh did come down from heaven, but He attributed what belongs to God to the man on account of the unity of the Person and the unity of the Hypostasis, so here again He attributes what belongs to the man to God the Word. "God gave," He says, "His Son to death." Although God remained impassible, yet since by Hypostasis One and the Same was both God the Word and Man subject to suffering, it is said that the Son is given over to death, who indeed also suffered in His own flesh.
What is the benefit of the Son being given? It is great and inconceivable for man — that everyone who believes in Him should receive two blessings: one, that he should not perish; the other, that he should have life, and moreover eternal life. The Old Testament promised long life to those who pleased God in it, but the Gospel rewards such people with life not temporal, but eternal and indestructible.

Above, the Lord assigned as the cause of spiritual regeneration the coming down of the Son and the lifting up of the Son of Man; and he set forth its fruit, which is eternal life. But this fruit seemed unbelievable to men laboring under the necessity of dying. And so now the Lord explains this. First, he proves the greatness of the fruit from the greatness of God's love. Secondly, he rejects a certain reply (v 17).

Here we should note that the cause of all our good is the Lord and divine love. For to love is, properly speaking, to will good to someone. Therefore, since the will of God is the cause of things, good comes to us because God loves us. And God's love is the cause of the good of nature: "You love everything which exists" (Wis 11:25). It is also the cause of the good which is grace: "I have loved you with an everlasting love, and so I have drawn you" i.e., through grace (Jer 31:3). But it is because of his great love that he gives us the good of glory. So he shows us here, from four standpoints, that this love of God is the greatest.

First, from the person of the one loving, because it is God who loves, and immeasurably. So he says, For God so loved: "He has loved the people; all the holy ones are in his hand" (Dt 33:3). Secondly, from the condition of the one who is loved, because it is man, a bodily creature of the world, i.e., existing in sin: "God shows his love for us, because while we were still his enemies, we were reconciled to God by the death of his Son" (Rom 5:8). Thus he says, the world. Thirdly, from the greatness of his gifts, for love is shown by a gift; as Gregory says: "The proof of love is given by action." But God has given us the greatest of gifts, his Only Begotten Son, and so he says, that he gave his Only Begotten Son. "God did not spare his own Son, but delivered him up for all of us" (Rom 8:32).

He says his Son, i.e., his natural Son, consubstantial, not an adopted son, i.e., not those sons of which the Psalmist says: "I said: You are gods" (Ps 81:6). This shows that the opinion of Arius is false: for if the Son of God were a creature, as he said, the immensity of God's love through the taking on of infinite goodness, which no creature can receive, could not have been revealed in him. He further says Only Begotten, to show that God does not have a love divided among many sons, but all of it is for that Son whom he gave to prove the immensity of his love: "For the Father loves the Son, and shows him everything that he does" (below 5:20).

Fourthly, from the greatness of its fruit, because through him we have eternal life. Hence he says, so that whoever believes in him should not perish, but have eternal life, which he obtained for us through the death of the cross.

But did God give his Son with the intention that he should die on the cross? He did indeed give him for the death of the cross inasmuch as he gave him the will to suffer on it. And he did this in two ways. First, because as the Son of God he willed from eternity to assume flesh and to suffer for us; and this will he had from the Father. Secondly, because the will to suffer was infused into the soul of Christ by God.

Note that above, when the Lord was speaking about the coming down which belongs to Christ according to his divinity, he called him the Son of God; and this because of the one suppositum of the two natures, as was explained above. And so divine things can be said about the suppositum of the human nature, and human things can be said about the suppositum of the divine nature, but not with reference to the same nature. Rather, divine things are said with reference to the divine nature, and human things with reference to the human nature. Now the specific reason why he here calls him the Son of God is that he set forth that gift as a sign of the divine love, through which the fruit of eternal life comes to us. And so, he should have been called by that name which indicates the power that produces eternal life; and this power is not in Christ as Son of Man but as Son of God: "This is the true God and eternal life," as we read in 1 John (5:20); "In him was life" (above 1:4).

Note also that he says, should not perish. Someone is said to be perishing when he is hindered from arriving at the end to which he is ordained. But the end to which man is ordained is eternal life, and as long as he sins, he turns himself from that end. And although while he is living he cannot entirely perish in the sense that he cannot be restored, yet when he dies in sin, then he entirely perishes: "The way of the wicked will perish" (Ps 1:7).

He indicates the immensity of God's love in saying, have eternal life: for by giving eternal life, he gives himself. For eternal life is nothing else than enjoying God. But to give oneself is a sign of great love: "But God, who is rich in mercy, has brought us to life in Christ" (Eph 2:5), i.e., he gave us eternal life.

But as soon as you look at any real Christian writings, you find that they are talking about something quite different from this popular religion. They say that Christ is the Son of God (whatever that means). They say that those who give Him their confidence can also become Sons of God (whatever that means). They say that His death saved us from our sins (whatever that means).

To beget is to become the father of: to create is to make. And the difference is this. When you beget, you beget something of the same kind as yourself. A man begets human babies, a beaver begets little beavers and a bird begets eggs which turn into little birds. But when you make, you make something of a different kind from yourself. A bird makes a nest, a beaver builds a dam, a man makes a wireless set—or he may make something more like himself than a wireless set: say, a statue. If he is a clever enough carver he may make a statue which is very like a man indeed. But, of course, it is not a real man; it only looks like one. It cannot breathe or think. It is not alive.

Now that is the first thing to get clear. What God begets is God; just as what man begets is man. What God creates is not God; just as what man makes is not man. That is why men are not Sons of God in the sense that Christ is.
