but whoever does not believe is already judged,
since he does not believe in the name of the
Only Begotten Son of God.
19 The judgment of condemnation is this:
the light came into the world,
and men loved darkness more than the light,
because their deeds were evil.
20 Everyone who practices evil hates the light,
and does not approach the light
for fear that his deeds might be exposed.
21 But everyone who practices the truth
comes to the light,
to make clear that his deeds are done in God.”
476 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).
477 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.
478 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.
479 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).
480 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.
481 Here the Lord excludes an objection that might be made. For in the old law it was promised that the Lord would come to judge: “The Lord will come to judge” (Is 3:14). So someone might say that the Son of God had not come to give eternal life but in order to judge the world. The Lord rejects this. First, he shows that he has not come to judge. Secondly, he proves it (v 18).
482 So he says: The Son of God has not come to judge, because God did not send his Son, referring to his first coming, into the world to judge the world, but that the world might be saved through him. The same thing is found below (12:47): “I did not come to judge the world, but to save the world.”
Now man’s salvation is to attain to God: “My salvation is in God” (Ps 61:8). And to attain to God is to obtain eternal life; hence to be saved is the same as to have eternal life. However, because the Lord says, “I did not come to judge the world,” men should not be lazy or abuse God’s mercy, or give themselves over to sin: because although in his first coming he did not come to judge but to forgive, yet in his second coming, as Chrysostom says, he will come to judge but not to forgive. “At the appointed time I will judge with rigor” (Ps 74:3).
