If I spoke of earthly things, and you did not believe, how will you believe if I tell you of heavenly things? As if to say: If you do not believe in a spiritual generation occurring in time, how will you believe in the eternal generation of the Son? Or, if you do not believe what I tell you about the power of my body, how will you believe what I tell you about the power of my divinity and about the power of the Holy Spirit?
465 Jesus replied. Here he answers the question. First, he lays down the causes of spiritual regeneration. Secondly, he explains what he says (3:16). Now there are two causes of spiritual regeneration, namely, the mystery of the incarnation of Christ, and his passion. So first, he treats of the incarnation; secondly, of the passion (3:14).
466 Here we should consider, first of all, how this answer of Christ is an adequate reply to the question of Nicodemus. For above, when the Lord was speaking of the Spirit, he said: you do not know where it comes from or where it goes. We understand by this that spiritual regeneration has a hidden source and a hidden end. Now the things in heaven are hidden from us: “Who will search out the things in heaven?” (Wis 9:16). Therefore, the sense of Nicodemus’ question, How can all this happen? is this: How can something come from the secret things of heaven or go to the secret things of heaven? So before answering, the Lord expressed this interpretation of the question, saying, how will you believe if I tell you of heavenly things?
And immediately he begins to show whose prerogative it is to ascend into heaven, namely, anyone who came down from heaven, according to the statement of Ephesians (4:10): “He who descended is he who ascended.” This is verified even in natural things, namely, that each body tends to a place according to its origin or nature. And so in this way it can come about that someone, through the Spirit, may go to a place which carnal persons do not know, i.e., by ascending into heaven, if this is done through the power of one who descended from heaven: because he descended in order that, in ascending, he might open a way for us: “He ascends, opening the way before them” (Mi 2:13).
467 Some have fallen into error because of his saying, the One who came down from heaven, the Son of Man. For since Son of Man designates human nature, which is composed of soul and body, then because he says that the Son descended from heaven, Valentinus wanted to maintain that he even took his body from heaven and thus passed through the Virgin without receiving anything from her, as water passes through a pipe; so that his body was neither of an earthly substance nor taken from the Virgin. But this is contrary to the statement of the Apostle, writing to the Romans (1:3): “who was made from the seed of David according to the flesh.”
On the other hand, Origen said that he descended from heaven as to his soul, which, he says, had been created along with the angels from the very beginning, and that later this soul descended from heaven and took flesh from the Virgin. But this also conflicts with the Catholic faith, which teaches that souls do not exist before their bodies.
468 Therefore, we should not understand that the Son of Man descended from heaven according to his human nature, but only according to his divine nature. For since in Christ there is one suppositum , or hypostasis, or person of the two natures, the divine and human natures, then no matter from which of these two natures this suppositum is named, divine and human things can be attributed to him. For we can say that the Son of Man created the stars and that the Son of God was crucified. But the Son of God was crucified, not according to his divine nature, but according to his human nature; and the Son of Man created the stars according to his divine nature. And so in things that are said of Christ, the distinction is not to be taken with respect to that about which they are said, because divine and human things are said of God and man indifferently; but a distinction must be made with respect to that according to which they are said, because divine things are said of Christ according to his divine nature, but human things according to his human nature. Thus, to descend from heaven is said of the Son of Man, not according to his human nature, but according to his divine nature, according to which it was appropriate to him to have been from heaven before the incarnation, as is said, “Heaven belongs to the Lord” (Ps 113:16).
469 he is said to have come down, but not by local motion, because then he would not have remained in heaven; for nothing which moves locally remains in the place from which it comes down. And so to exclude local motion, he adds, who lives in heaven. As if to say: He descended from heaven in such a way as yet to be in heaven. For he came down from heaven without ceasing to be above, yet assuming a nature which is from below. And because he is not enclosed or held fast by his body which exists on earth, he was, according to his divinity, in heaven and everywhere. And therefore to indicate that he is said to have come down in this way, because he assumed a [human] nature, he said, the Son of Man came down, i.e., insofar as he became Son of Man.
470 Or it can be said, as Hilary does, that he came down from heaven as to his body: not that the material of Christ’s body came down from heaven, but that the power which formed it was from heaven.
471 But why does he say, No one has gone up to heaven except the Son of Man, who lives in heaven? For have not Paul and Peter and the other saints gone up, according to 2 Corinthians (5:1): “We have a house in the heavens.” I answer that no one goes up into heaven except Christ and his members, i.e., those believers who are just. Accordingly, the Son of God came down from heaven in order that, by making us his members, he might prepare us to ascend into heaven: now, indeed, in hope, but later in reality. “He has raised us up, and has given us a place in heaven in Christ Jesus” (Eph 2:6).
472 Here he mentions the mystery of the passion, in virtue of which baptism has its efficacy: “We who have been baptized into Christ Jesus, have been baptized into his death” (Rom 6:3). And with regard to this he does three things. First, he gives a symbol for the passion. Secondly, the manner of the passion. Thirdly, the fruit of the passion.
473 He takes the symbol from the old law, in order to adapt to the understanding of Nicodemus; so he says, Just as Moses lifted up the serpent in the desert. This refers to Numbers (21:5) when the Lord, faced with the Jewish people saying, “We are sick of this useless food,” sent serpents to punish them; and when the people came to Moses and he interceded with the Lord, the Lord commanded that for a remedy they make a serpent of bronze; and this was to serve both as a remedy against those serpents and as a symbol of the Lord’s passion. Hence it says that this bronze serpent was lifted up as a sign (Nm 21:9).
Now it is characteristic of serpents that they are poisonous, but not so the serpent of bronze, although it was a symbol of a poisonous serpent. So, too, Christ did not have sin, which is also a poison: “Sin, when it is fully developed, brings forth death” (Jas 1:15); but he had the likeness of sin: “God sent his own Son, in the likeness of sinful flesh” (Rom 8:3). And thus Christ had the effect of the serpent against the insurgence of inflamed concupiscences.
474 He shows the manner of the passion when he says, so must the Son of Man be lifted up: and this refers to the lifting up of the cross. So below (12:34) when it says, “The Son of Man must be lifted up,” it also has, “He said this to indicate the manner of his death.”
He willed to die lifted up, first of all, to cleanse the heavens: for since he had cleansed the things on earth by the sanctity of his life, the things of the air were left to be cleansed by his death: “through him he should reconcile all things to himself, whether on earth or in the heavens, making peace through his blood” (Col 1:20). Secondly, to triumph over the demons who prepare for war in the air: “the prince of the power of the air” (Eph 2:2). Thirdly, he wished to die lifted up to draw our hearts to himself: “I, if I am lifted up from the earth, will draw all to myself” (below 12:32). And fourthly, because in the death of the cross he was lifted up in the sense that there he triumphed over his enemies; so it is not called a death, but a lifting up: “He will drink from the stream on the way, therefore he will lift up his head” (Ps 109:7). Fifthly, he willed to die lifted up because the cross was the reason for his being lifted up, i.e., exalted: “He became obedient to the Father even to death, the death of the cross; on account of which God has exalted him” (Phil 2:8).
475 Now the fruit of Christ’s passion is eternal life; hence he says, so that everyone who believes in him, performing good works, may not be lost, but have eternal life. And this fruit corresponds to the fruit of the symbolic serpent. For whoever looked upon the serpent of bronze was freed from poison and his life was preserved. But he who looks upon the lifted up Son of Man, and believes in the crucified Christ, he is freed from poison and sin: “Whoever believes in me will never die” (below 11:26), and is preserved for eternal life. “These things are written that you may believe... and that believing you may have life in his name” (below 20:31).
