Physical or Spiritual Birth

I do not believe baptism is New Testament circumcision, since our circumcision is performed by God without hands. It is performed in baptism one might say.

One mistake of Catholics that led to infant baptism is they correlate our circumcision with physical birth instead of spiritual birth.

Our spiritual birth is when we believe the Gospel. Thus our circumcision must occur at our conversion to Christ.

Even if you correlate baptism with circumcision, it does not mean physical infants, but spiritual infants. People who come to know the basics of the Gospel.

Heb 5:12  For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.

Heb 5:13  For every one that useth milk is unskilful in the word of righteousness: for he is a babe.

Notice that Paul does not consider a babe to be one of total ignorance such as a new born infant.

A babe was one taught basic principles corresponding to the basic faith of Christ.

Heb 6:1  Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,

Heb 6:2  Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.

If you realize babes in Christ were not new born physical infants, but new born spiritual infants, with a basic understanding of the doctrines of Christ.

Jesus articulated the difference in John 3.

Joh 3:6  That which is bornG1080 ofG1537 theG3588 fleshG4561 isG2076 flesh;G4561 andG2532 that which is bornG1080 ofG1537 theG3588 SpiritG4151 isG2076 spirit.G4151

Baptism is tied to our spiritual birth by Christ, Peter, and John. Not our physical birth.

1Pe 1:23  Being born again,G313 notG3756 ofG1537 corruptibleG5349 seed,G4701 butG235 of incorruptible,G862 byG1223 the wordG3056 of God,G2316 which livethG2198 andG2532 abidethG3306 for ever.G1519 G165

Joh 1:13  WhichG3739 were born,G1080 notG3756 ofG1537 blood,G129 norG3761 ofG1537 the willG2307 of the flesh,G4561 norG3761 ofG1537 the willG2307 of man,G435 butG235 ofG1537 God.G2316
