As usual - your aberrant doctrines are base on one of the MAJOR aberrant doctrines o the Protestant Revolt:
SOLA SCRIPTURA
NOWHERE does the Bible state that everything ewe believe and practice must be explicitly taught on the pages of Scripture. his is a Protestant invention - NOT a Biblical truth.
HOWEVER - the implicit teaching on Infant Baptism is absolutely in Scripture:
- We see the ENTIRE HOUSEHOLD of Cornelius being baptized based on HIS faith (Acts 10:47-48).
- We see the ENTIRE HOUSEHOLD of the Philippian Jailer being baptized based on HIS faith (Acts 16:31-34).
- We see the ENTIRE HOUSEHOLD of Stephanas being baptized (1 Cor. 1:16, 16:15).
Gee, I hate to be the one to break this to you but "Entire Households" had people of EVERY age living in them - from infants to the very old.
In Acts 2:39, Peter said about Baptismal regeneration, "The promise is for you and your CHILDREN and for all who are far off—for all whom the Lord our God will call."
Now for some actual historical proof of the APOSTOLIC Tradition handed down to the Early Church regarding Infant Baptism:
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]).
