The Weight of Evidence is Against Adults-only Baptism
Although many Protestant traditions baptize babies, Baptists—and “Bible churches” in the Baptist tradition—insist that baptism is only for those who have come to faith. Nowhere in the New Testament, they point out, do we read of infants being baptized.
On the other hand, nowhere do we read of children raised in believing households reaching the age of reason and then being baptized. The only explicit baptism accounts in the Bible involve converts from Judaism or paganism. For children of believers there is no explicit mention of baptism—either in infancy or later.
This poses a problem for Baptists and Bible Christians: On what basis do they require children of believers to be baptized at all? Given the silence of the New Testament, why not assume Christian baptism is only for adult converts?
