Baptism of infants is biblical because circumcision in the Old Testament meant the same thing as baptism does in the New, and there are no scriptures in the New Testament that state that infants of believers are now to be treated differently in the New Covenant from the way that infants of Israelite children were treated in the Old! The norm of the Old Covenant always treated Israelite chrildren as part of the covenant community. There is nothing that changes this norm by informing us that children of Christians are to be treated as "outside" the covenant community. In fact, the trend of the New Testament was actually to include people who used to be considered "outside". For example, gentiles, people excluded from the covenant community in the Old Covenant, now make up the majority of the church. Women worship with men in Christian congregations instead of in a separate courtyard outside the temple, and females as well as males are included in New Covenant baptism. Peter told his audience, "Acts 2:38-39 (ESV) Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.  For the promise is for you and for your children and for all who are far off , everyone whom the Lord our God calls to himself." In view of all this, the argument which states that there is no scriptural evidence of infants being baptized in the New Testament holds no water! Including children was already the "norm" and if we are looking for New Testament evidence, we should be looking for scriptures that would deny baptism to infants and not the other way around. Both baptism and circumcision were signs of the righteousness we receive by faith and baptism came in the room of circumcision in the New Copvenant: Col. 2:11-13 (ESV) In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, having been buried with him in baptism , in which you were also raised with him through faith in the powerful working of God, who raised him from the dead.  And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, Romans 4:11 (ESV) He received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was to make him the father of all who believe without being circumcised, so that righteousness would be counted to them as well, Deut. 30:6 (ESV) And the Lord your God will circumcise your heart and the heart of your offspring, so that you will love the Lord your God with all your heart and with all your soul, that you may live. Ezekiel 36:24-27 (ESV) I will take you from the nations and gather you from all the countries and bring you into your own land.  I will sprinkle clean water on you, and you shall be clean from all your uncleannesses, and from all your idols I will cleanse you.  And I will give you a new heart, and a new spirit I will put within you. And I will remove the heart of stone from your flesh and give you a heart of flesh.  And I will put my Spirit within you, and cause you to walk in my statutes and be careful to obey my rules. All little children are part of the family of God under any covenant and circumcision was applied before they understood anything about it or before anyone had any knowledge as to whether they would receive the spiritual blessings it symbolized when they reached the age of accountability. This rules out the idea that, since an infant is unable to believe for himself, that he should not be baptized! They are already saved, so they should be allowed to receive the sign of salvation like any believer. When they reach the age of accountability, being brought up by godly parents, then they receive Christ for themselves and it is at this time that their baptism becomes meaningful to them. The bible always instructs "adults" who were converted out of Judaism and Paganism to be baptized as believers, but this was before the "christian family" had time to develop! Everyone would instruct unconverted adults to "believe" before baptism but this doesn't exclude infants born into christian families! The New Testament never tells us about a single adolescent or young adult who had been raised from infancy by parents in christian homes who later received baptism only after he or she expressed faith in Christ! There is not "one shred" of scripture that says that infants born into christian homes should not be baptized!
