But John 3:5 has nothing to do with baptism.
Just try to use Scripture accurately.
Acts 1:8 my witnesses
Acts 2:42 doctrine of the apostles
A) "It does not suffice to believe. He who believes and is not yet baptized, but is only a Catechumen, has not yet fully acquired salvation." St. Thomas Aquinas
B) "Now, even the Catechumen believes in the Cross of the Lord Jesus, but unless he be baptized in the name of the Father and of the Son and of the Holy Ghost, he cannot receive remission of his sins nor the gift of spiritual grace." St. Ambrose
C) "Without the Sacrament of Baptism, no one is ever justified. If anyone says that Baptism is optional, that is, not necessary for salvation: let him be anathema." Council of Trent
D)
“There are three ways in which sins are forgiven: in baptism, in prayer, and in the greater humility of penance; yet God does not forgive sins except to the baptized” (Sermons to Catechumens on the Creed 7:15 [A.D. 395]).
St. AUGUSTINE
E) “As many as are persuaded and believe that what we [Christians] teach and say is true, and undertake to be able to live accordingly . . . 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 Lord of the universe, and of our Savior Jesus Christ, and of the Holy Spirit, they then receive the washing with water. For Christ also said, ‘Except you be born again, you shall not enter into the kingdom of heaven’ [John 3:3]” (First Apology 61 [A.D. 151]).
JUSTIN MARTYR
TERTULLIAN
“Happy is our sacrament of water, in that, by washing away the sins of our early blindness, we are set free and admitted into eternal life. . . . [But] a viper of the [Gnostic] Cainite heresy, lately conversant in this quarter, has carried away a great number with her most venomous doctrine, making it her first aim to destroy baptism—which is quite in accordance with nature, for vipers and.asps . . . themselves generally do live in arid and waterless places. But we, little fishes after the example of our [Great] Fish, Jesus Christ, are born in water, nor have we safety in any other way than by permanently abiding in water. So that most monstrous creature, who had no right to teach even sound doctrine, knew full well how to kill the little fishes—by taking them away from the water!” (Baptism 1 [A.D. 203]).
“Without baptism, salvation is attainable by none” (ibid., 12).
ORIGEN
“It is not possible to receive forgiveness of sins without baptism” (Exhortation to the Martyrs 30 [A.D. 235]).
CYRIL OF JERUSALEM
“If any man does not receive baptism, he does not have salvation.
St. AUGUSTINE
“There are three ways in which sins are forgiven: in baptism, in prayer, and in the greater humility of penance; yet God does not forgive sins except to the baptized” (Sermons to Catechumens on the Creed 7:15 [A.D. 395]).
POPE LEO I
“And because of the transgression of the first man, the whole stock of the human race was tainted; no one can be set free from the state of the old Adam save through Christ’s sacrament of baptism, in which there are no distinctions between the reborn, as the apostle [Paul] says, ‘For as many of you as were baptized in Christ did put on Christ; there is neither Jew nor Greek . . . ‘ [Gal. 3:27–28]” (Letters 15:10[11] [A.D. 445]).
FULGENTIUS OF RUSPE
“From that time at which our Savior said, ‘If anyone is not reborn of water and the Spirit, he cannot enter into the kingdom of heaven’ [John 3:5], no one can, without the sacrament of baptism, except those who, in the Catholic Church, without baptism, pour out their blood for Christ, receive the kingdom of heaven and life eternal” (The Rule of Faith 43 [A.D. 524]).
Irenaeus
He [Jesus] came to save all through himself – all, I say, who through him are reborn in God; INFANTS, and children, and youths, and old men. Therefore he passed through every age, becoming an INFANT for INFANTS, sanctifying INFANTS; a child for children, sanctifying those who are of that age . . . [so that] he might be the perfect teacher in all things, perfect not only in respect to the setting forth of truth, perfect also in respect to relative age (Against Heresies 2:22:4 [A.D. 189]).
Hippolytus
Baptize first the children, and if they can speak for themselves let them do so. Otherwise, let their parents or other relatives speak for them (The Apostolic Tradition 21:16 [A.D.215]).
Origen
THE CHURCH RECEIVED FROM THE APOSTLES the tradition of giving baptism even to infants. The APOSTLES, to whom were committed the secrets of divine sacraments, knew there is in everyone innate strains of [original] sin, which must be washed away through water and the Spirit (Commentaries on Romans 5:9 [A.D. 248]).
Cyprian
As to what pertains to the case of INFANTS: You [Fidus] said that they ought not to be baptized within the second or third day after their birth, that the old law of circumcision must be taken into consideration, and that you did not think that one should be baptized and sanctified within the eighth day after his birth. In our council it seemed to us far otherwise. No one agreed to the course which you thought should be taken. Rather, we all judge that the mercy and grace of God ought to be denied to no man born" (Letters 64:2 [A.D. 253]).
Augustine
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 [A.D. 408]).
