Fundamentalists often criticize the Catholic Church’s practice of baptizing infants. According to them, baptism is for adults and older children, because it is to be administered only after one has undergone a "born again" experience—that is, after one has "accepted Jesus Christ as his personal Lord and Savior." At the instant of acceptance, when he is "born again," the adult becomes a Christian, and his salvation is assured forever. Baptism follows, though it has no actual salvific value. In fact, one who dies before being baptized, but after "being saved," goes to heaven anyway.
As Fundamentalists see it, baptism is not a sacrament (in the true sense of the word), but an ordinance. It does not in any way convey the grace it symbolizes; rather, it is merely a public manifestation of the person’s conversion. Since only an adult or older child can be converted, baptism is inappropriate for infants or for children who have not yet reached the age of reason (generally considered to be age seven). Most Fundamentalists say that during the years before they reach the age of reason infants and young children are automatically saved. Only once a person reaches the age of reason does he need to "accept Jesus" in order to reach heaven.
Since the New Testament era, the Catholic Church has always understood baptism differently, teaching that it is a sacrament which accomplishes several things, the first of which is the remission of sin, both original sin and actual sin—only original sin in the case of infants and young children, since they are incapable of actual sin; and both original and actual sin in the case of older persons.
Peter explained what happens at baptism when he said, "Repent, and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins; and you shall receive the gift of the Holy Spirit" (Acts 2:38). But he did not restrict this teaching to adults. He added, "For the promise is to you and to your children and to all that are far off, every one whom the Lord our God calls to him" (2:39). We also read: "Rise and be baptized, and wash away your sins, calling on his name" (Acts 22:16). These commands are universal, not restricted to adults. Further, these commands make clear the necessary connection between baptism and salvation, a connection explicitly stated in 1 Peter 3:21: "Baptism . . . now saves you, not as a removal of dirt from the body but as an appeal to God for a clear conscience, through the resurrection of Jesus Christ."
Fundamentalists try to ignore the historical writings from the early Church which clearly indicate the legitimacy of infant baptism. They attempt to sidestep appeals to history by saying baptism requires faith and, since children are incapable of having faith, they cannot be baptized. It is true that Christ prescribed instruction and actual faith for adult converts (Matt. 28:19–20), but his general law on the necessity of baptism (John 3:5) puts no restriction on the subjects of baptism. Although infants are included in the law he establishes, requirements of that law that are impossible to meet because of their age are not applicable to them. They cannot be expected to be instructed and have faith when they are incapable of receiving instruction or manifesting faith. The same was true of circumcision; faith in the Lord was necessary for an adult convert to receive it, but it was not necessary for the children of believers.
Furthermore, the Bible never says, "Faith in Christ is necessary for salvation except for infants"; it simply says, "Faith in Christ is necessary for salvation." Yet Fundamentalists must admit there is an exception for infants unless they wish to condemn instantaneously all infants to hell. Therefore, the Fundamentalist himself makes an exception for infants regarding the necessity of faith for salvation. He can thus scarcely criticize the Catholic for making the exact same exception for baptism, especially if, as Catholics believe, baptism is an instrument of salvation.
It becomes apparent, then, that the Fundamentalist position on infant baptism is not really a consequence of the Bible’s strictures, but of the demands of Fundamentalism’s idea of salvation. In reality, the Bible indicates that infants are to be baptized, that they too are meant to inherit the kingdom of heaven. Further, the witness of the earliest Christian practices and writings must once and for all silence those who criticize the Catholic Church’s teaching on infant baptism. The Catholic Church is merely continuing the tradition established by the first Christians, who heeded the words of Christ: "Let the children come to me, and do not hinder them; for to such belongs the kingdom of God" (Luke 18:16).
