Lectures or Tractates on the Gospel According to St. John: Tractate XI
4. Therefore, since Nicodemus was of that number, he came to the Lord, but came by night; and this perhaps pertains to the matter. Came to the Lord, and came by night; came to the Light, and came in the darkness. But what do they that are born again of water and of the Spirit hear from the apostle? “Ye were once darkness, but now light in the Lord; walk as children of light;” and again, “But we who are of the day, let us be sober.” Therefore they who are born again were of the night, and are of the day; were darkness, and are light. Now Jesus trusts Himself to them, and they come to Jesus, not by night, like Nicodemus; not in darkness do they seek the day. For such now also profess: Jesus has come near to them, has made salvation in them; for He said, “Except a man eat my flesh, and drink my blood, he shall not have life in him.” And as the catechumens have the sign of the cross on their forehead, they are already of the great house; but from servants let them become sons. For they are something who already belong to the great house. But when did the people Israel eat the manna? After they had passed the Red Sea. And as to what the Red Sea signifies, hear the apostle: “Moreover, brethren, I would not have you ignorant, that all our fathers were under the cloud, and all passed through the sea.” To what purpose passed they through the sea? As if thou wert asking of him, he goes on to say, “And all were baptized by Moses in the cloud and in the sea.” Now, if the figure of the sea had such efficacy, how great will be the efficacy of the true form of baptism! If what was done in a figure brought the people, after they had crossed over, to the manna, what will Christ impart, in the verity of His baptism, to His own people, brought over through Himself? By His baptism He brings over them that believe; all their sins, the enemies as it were that pursue them, being slain, as all the Egyptians perished in that sea. Whither does He bring over, my brethren? Whither does Jesus bring over by baptism, of which Moses then showed the figure, when he brought them through the sea? Whither? To the manna. What is the manna? “I am,” saith He, “the living bread, which came down from heaven.” The faithful receive the manna, having now been brought through the Red Sea? Why Red Sea? Besides sea, why also “red”? That “Red Sea” signified the baptism of Christ. How is the baptism of Christ red, but as consecrated by Christ’s blood? Whither, then, does He lead those that believe and are baptized? To the manna. Behold, “manna,” I say: what the Jews, that people Israel, received, is well known, well known what God had rained on them from heaven; and yet catechumens know not what Christians receive. Let them blush, then, for their ignorance; let them pass through the Red Sea, let them eat the manna, that as they have believed in the name of Jesus, so likewise Jesus may trust Himself to them.
5. Therefore mark, my brethren, what answer this man who came to Jesus by night makes. Although he came to Jesus, yet because he came by night, he still speaks from the darkness of his own flesh. He understands not what he hears from the Lord, understands not what he hears from the Light, “which lighteth every man that cometh into this world.” Already hath the Lord said to him, “Except a man be born again, he shall not see the kingdom of God. Nicodemus saith unto Him, How can a man be born again when he is old?” The Spirit speaks to him, and he thinks of the flesh. He thinks of his own flesh, because as yet he thinks not of Christ’s flesh. For when the Lord Jesus had said, “Except a man eat my flesh, and drink my blood, he shall not have life in him,” some who followed Him were offended, and said among themselves, “This is a hard saying; who can hear it?” For they fancied that, in saying this, Jesus meant that they would be able to cook Him, after being cut up like a lamb, and eat Him: horrified at His words, they went back, and no more followed Him. Thus speaks the evangelist: “And the Lord Himself remained with the twelve; and they said to Him, Lo, those have left Thee. And He said, Will ye also go away?”—wishing to show them that He was necessary to them, not they necessary to Christ. Let no man fancy that he frightens Christ, when he tells Him that he is a Christian; as if Christ will be more blessed if thou be a Christian. It is a good thing for thee to be a Christian; but if thou be not, it will not be ill for Christ. Hear the voice of the psalm, “I said to the Lord, Thou art my God, since Thou hast no need of my goods.” For that reason, “Thou art my God, since of my goods Thou hast no need.” If thou be without God, thou wilt be less; if thou be with God, God will not be greater. Not from thee will He be greater, but thou without Him wilt be less. Grow, therefore, in Him; do not withdraw thyself, that He may, as it were, diminish. Thou wilt be renewed if thou come to Him, wilt suffer loss if thou depart from Him. He remains entire when thou comest to Him, remains entire even when thou fallest away. When, therefore, He had said to His disciples, “Will ye also go away?” Peter, that Rock, answered with the voice of all, “Lord, to whom shall we go?
Thou hast the words of eternal life.” Pleasantly savored the Lord’s flesh in his mouth. The Lord, however, expounded to them, and said, “It is the Spirit that quickeneth.” After He had said, “Except a man eat my flesh, and drink my blood, he shall not have life in him,” lest they should understand it carnally, He said, “It is the Spirit that quickeneth, but the flesh profiteth nothing: the words which I have spoken unto you are spirit and life.”
6. This Nicodemus, who had come to Jesus by night, did not savor of this spirit and this life. Saith Jesus to him, “Except a man be born again, he shall not see the kingdom of God.” And he, savoring of his own flesh, while as yet he savored not of the flesh of Christ in his mouth, saith, “How can a man be born a second time, when he is old? Can he enter a second time into his mother’s womb, and be born?” This man knew but one birth, that from Adam and Eve; that which is from God and the Church he knew not yet: he knew only those parents that bring forth to death, knew not yet the parents that bring forth to life; he knew but the parents that bring forth successors, knew not yet the ever-living parents that bring forth those that shall abide.
Whilst there are two births, then, he understood only one. One is of the earth, the other of heaven; one of the flesh, the other of the Spirit; one of mortality, the other of eternity; one of male and female, the other of God and the Church. But these two are each single; there can be no repeating the one or the other. Rightly did Nicodemus understand the birth of the flesh; so understand thou also the birth of the Spirit, as Nicodemus understood the birth of the flesh. What did Nicodemus understand? “Can a man enter a second time into his mother’s womb, and be born?” Thus, whosoever shall tell thee to be spiritually born a second time, answer in the words of Nicodemus, “Can a man enter a second time into his mother’s womb, and be born?” I am already born of Adam, Adam cannot beget me a second time. I am already born of Christ, Christ cannot beget me again. As there is no repeating from the womb, so neither from baptism.
7. He that is born of the Catholic Church, is born, as it were, of Sarah, of the free woman; he that is born of heresy is, as it were, born of the bond woman, but of Abraham’s seed. Consider, beloved, how great a mystery. God testifies, saying, “I am the God of Abraham, and the God of Isaac, and the God of Jacob.” Were there not other patriarchs? Before these, was there not holy Noah, who alone of the whole human race, with all his house, was worthy to be delivered from the flood,—he in whom, and in his sons, the Church was prefigured? Borne by wood, they escaped the flood. Then afterwards great men whom we know, whom Holy Scriptures commends, Moses faithful in all his house. And yet those three are named, just as if they alone deserved well of him: “I am the God of Abraham, and the God of Isaac, and the God of Jacob: this is my name for ever.” Sublime mystery! It is the Lord that is able to open both our mouth and your hearts, that we may speak as He has deigned to reveal, and that you may receive even as it is expedient for you.
