There was a man named Nicodemus, a Jewish religious leader who was a Pharisee. After dark one evening, he came to speak with Jesus. “Rabbi,” he said, “we all know that God has sent you to teach us. Your miraculous signs are evidence that God is with you.”
Jesus replied, “I tell you the truth, unless you are born again, you cannot see the Kingdom of God.”
“What do you mean?” exclaimed Nicodemus. “How can an old man go back into his mother’s womb and be born again?”
Jesus replied, “I assure you, no one can enter the Kingdom of God without being born of water and the Spirit. Humans can reproduce only human life, but the Holy Spirit gives birth to spiritual life. So don’t be surprised when I say, ‘You must be born again.’ The wind blows wherever it wants. Just as you can hear the wind but can’t tell where it comes from or where it is going, so you can’t explain how people are born of the Spirit.” (John 3:1-8 NLT)
No Church Father referred to John 3:5 as anything other than water baptism.
“As many as are persuaded and believe that what we teach and say is true, and undertake to be able to live accordingly, and instructed to pray and to entreat God with fasting, for the remission of their sins that are past, we pray and fast with them. Then they are brought by us where there is water and are regenerated in the same manner in which we were ourselves regenerated. For, in the name of God, the Father . . . and of our Savior Jesus Christ, and of the Holy Spirit , they then receive the washing with water. For Christ also said, ‘Unless you are born again, you shall not enter into the kingdom of heaven’ ” (First Apology 61 ).
“‘And dipped himself . . . seven times in the Jordan’ . It was not for nothing that Naaman of old, when suffering from leprosy, was purified upon his being baptized, but as an indication to us. For as we are lepers in sin, we are made clean, by means of the sacred water and the invocation of the Lord, from our old transgressions, being spiritually regenerated as newborn babes, even as the Lord has declared: ‘Except a man be born again through water and the Spirit, he shall not enter into the kingdom of heaven’” (Fragment 34 ).
“o one can attain salvation without baptism, especially in view of the declaration of the Lord, who says, ‘Unless a man shall be born of water, he shall not have life’” (Baptism 12:1 ).
“The Father of immortality sent the immortal Son and Word into the world, who came to man in order to wash him with water and the Spirit; and he, begetting us again to incorruption of soul and body, breathed into us the Spirit of life, and endued us with an incorruptible panoply. If, therefore, man has become immortal, he will also be God. And if he is made God by water and the Holy Spirit after the regeneration of the laver he is found to be also joint-heir with Christ after the resurrection from the dead. Wherefore I preach to this effect: Come, all ye kindreds of the nations, to the immortality of the baptism” (Discourse on the Holy Theophany 8 ).
The Recognitions of Clement
“But you will perhaps say, ‘What does the baptism of water contribute toward the worship of God?’ In the first place, because that which has pleased God is fulfilled. In the second place, because when you are regenerated and born again of water and of God, the frailty of your former birth, which you have through men, is cut off, and so . . . you shall be able to attain salvation; but otherwise it is impossible. For thus has the true prophet testified to us with an oath: ‘Verily, I say to you, that unless a man is born again of water . . . he shall not enter into the kingdom of heaven’” (The Recognitions of Clement 6:9 ).
Testimonies Concerning the Jews
“That unless a man have been baptized and born again, he cannot attain unto the kingdom of God. In the Gospel according to John: ‘Except a man be born again of water and the Spirit, he cannot enter into the kingdom of God’ . . . . Also in the same place: ‘Unless ye eat the flesh of the Son of man, and drink his blood, ye shall not have life in you’ . That it is of small account to be baptized and to receive the Eucharist, unless one profit by it both in deeds and works” (Testimonies Concerning the Jews 3:2:25–26 ).
Cyprian of Carthage
” they receive also the baptism of the Church . . . then finally can they be fully sanctified and be the sons of God . . . since it is written, ‘Except a man be born again of water and of the Spirit, he cannot enter into the kingdom of God’” (Letters 71:1 ).
Council of Carthage VII
“And in the gospel our Lord Jesus Christ spoke with his divine voice, saying, ‘Except a man be born again of water and the Spirit, he cannot enter the kingdom of God.’ . . . Unless therefore they receive saving baptism in the Catholic Church, which is one, they cannot be saved, but will be condemned with the carnal in the judgment of the Lord Christ” (Seventh Carthage ).
Cyril of Jerusalem
“Since man is of a twofold nature, composed of body and soul, the purification also is twofold: the corporeal for the corporeal and the incorporeal for the incorporeal. The water cleanses the body, and the Spirit seals the soul. . . . When you go down into the water, then, regard not simply the water, but look for salvation through the power of the Spirit. For without both you cannot attain to perfection. It is not I who says this, but the Lord Jesus Christ, who has the power in this matter. And he says, ‘Unless a man be born again,’ and he adds the words ‘of water and of the Spirit,’ ‘he cannot enter the kingdom of God.’ He that is baptized with water, but is not found worthy of the Spirit, does not receive the grace in perfection. Nor, if a man be virtuous in his deeds, but does not receive the seal by means of the water, shall he enter the kingdom of heaven. A bold saying, but not mine; for it is Jesus who has declared it” (Catechetical Lectures 3:4 ).
“s we are all from earth and die in Adam, so being regenerated from above of water and Spirit, in the Christ we are all quickened” (Four Discourses Against the Arians 3:26 ).
Basil the Great
“This then is what it means to be ‘born again of water and Spirit’: Just as our dying is effected in the water , our living is wrought through the Spirit. In three immersions and an equal number of invocations the great mystery of baptism is completed in such a way that the type of death may be shown figuratively, and that by the handing on of divine knowledge the souls of the baptized may be illuminated. If, therefore, there is any grace in the water, it is not from the nature of water, but from the Spirit’s presence there” (The Holy Spirit 15:35 ).
Ambrose of Milan
“Although we are baptized with water and the Spirit, the latter is much superior to the former, and is not therefore to be separated from the Father and the Son. There are, however, many who, because we are baptized with water and the Spirit, think that there is no difference in the offices of water and the Spirit, and therefore think that they do not differ in nature. Nor do they observe that we are buried in the element of water that we may rise again renewed by the Spirit. For in the water is the representation of death, in the Spirit is the pledge of life, that the body of sin may die through the water, which encloses the body as it were in a kind of tomb, that we, by the power of the Spirit, may be renewed from the death of sin, being born again in God” (The Holy Spirit 1:6 ).
“You have read, therefore, that the three witnesses in baptism are one: water, blood, and the Spirit (1 John 5:8): And if you withdraw any one of these, the sacrament of baptism is not valid. For what is the water without the cross of Christ? A common element with no sacramental effect. Nor on the other hand is there any mystery of regeneration without water, for ‘unless a man be born again of water and the Spirit, he cannot enter the kingdom of God’” (The Mysteries 4:20 ).
“The Church was redeemed at the price of Christ’s blood. Jew or Greek, it makes no difference; but if he has believed, he must circumcise himself from his sins so that he can be saved . . . for no one ascends into the kingdom of heaven except through the sacrament of baptism.
. . . ‘Unless a man be born again of water and the Holy Spirit, he cannot enter the kingdom of God’” (Abraham 2:11:79–84 ).
Gregory of Nyssa
” the birth by water and the Spirit, himself led the way in this birth, drawing down upon the water, by his own baptism, the Holy Spirit; so that in all things he became the firstborn of those who are spiritually born again, and gave the name of brethren to those who partook in a birth like to his own by water and the Spirit” (Against Eunomius 2:8 ).
“o one can enter into the kingdom of heaven except he be regenerated through water and the Spirit, and he who does not eat the flesh of the Lord and drink his blood is excluded from eternal life, and if all these things are accomplished only by means of those holy hands, I mean the hands of the priest, how will any one, without these, be able to escape the fire of hell, or to win those crowns which are reserved for the victorious? These truly are they who are entrusted with the pangs of spiritual travail and the birth which comes through baptism: by their means we put on Christ, and are buried with the Son of God, and become members of that blessed head ” (The Priesthood 3:5–6 ).
Gregory of Nazianz
“Such is the grace and power of baptism; not an overwhelming of the world as of old, but a purification of the sins of each individual, and a complete cleansing from all the bruises and stains of sin. And since we are double-made, I mean of body and soul, and the one part is visible, the other invisible, so the cleansing also is twofold, by water and the Spirit; the one received visibly in the body, the other concurring with it invisibly and apart from the body; the one typical, the other real and cleansing the depths” (Oration on Holy Baptism 7–8 ).
The Apostolic Constitutions
“Be ye likewise contented with one baptism alone, that which is into the death of the Lord . . . . e that out of contempt will not be baptized shall be condemned as an unbeliever and shall be reproached as ungrateful and foolish. For the Lord says, ‘Except a man be baptized of water and of the Spirit, he shall by no means enter into the kingdom of heaven.’ And again, ‘He that believes and is baptized shall be saved, but he that believes not shall be damned’” (Apostolic Constitutions 6:3:15 ).
“It is this one Spirit who makes it possible for an infant to be regenerated . . . when that infant is brought to baptism; and it is through this one Spirit that the infant so presented is reborn. For it is not written, ‘Unless a man be born again by the will of his parents’ or ‘by the faith of those presenting him or ministering to him,’ but, ‘Unless a man be born again of water and the Holy Spirit.’ The water, therefore, manifesting exteriorly the sacrament of grace, and the Spirit effecting interiorly the benefit of grace, both regenerate in one Christ that man who was generated in Adam” (Letters 98:2 ).
“Those who, though they have not received the washing of regeneration, die for the confession of Christ—it avails them just as much for the forgiveness of their sins as if they had been washed in the sacred font of baptism. For he that said, ‘If anyone is not reborn of water and the Spirit, he will not enter the kingdom of heaven,’ made an exception for them in that other statement in which he says no less generally, ‘Whoever confesses me before men, I too will confess him before my Father, who is in heaven’” (The City of God 13:7 ).
Paul was not speaking about written documents when he spoke of Tradition; he was speaking about teachings handed down:
And now, dear brothers and sisters, we give you this command in the name of our Lord Jesus Christ: Stay away from all believers who live idle lives and don’t follow the tradition they received from us. (2Th 3:6 NLT)
