1.) Following the conviction that there is no such thing as neutrality we Biblical Christians understand that if we do not baptize our children we are then presuming either they are not sinners and so have no need of the sign and seal of the washing of regeneration or we are presuming that our babies do indeed belong to their Father the devil and so are counted seed for Lucifer. Holding to neither of these presumptions, we presume, following Scripture, a charity regarding our children’s covenant identity and so following Scripture we baptize our children as God’s children.
2.) Infant Baptism is consistent with the proclamation that salvation is by faith alone through grace alone. The paedo-Baptists are consistent here. The Creedo-Baptists are not. The creedo-baptist by demanding an ability of a covenant child to confess Christ before he or she can be baptized is denying faith alone through grace alone because whatever the confessing creedo-Baptist person is bringing to Baptism that the covenant infant paedo-Baptist cannot bring (because they are an infant) is the something that is being added to so that faith alone through grace alone is being denied. As such there is a synergistic something in Creedo-Baptist beliefs. Creedo-Baptists are latent Arminians. This is a consequence of jamming together Ana-Baptist ecclesiology with Reformed soteriology.
3.) Scripture records the outrage of the Jews over the Gentiles being let into the Covenant community minus all the cultural accouterments of being Jewish. Yet, we are to believe that the Jews said nothing about their children being excluded from the covenant community in the new and better covenant where, per the Creedo-Baptists, the children were, for the first time ever, forbidden the sign and seal of covenant membership. Jews were outraged by Gentiles coming in but silent about their children being cast out.
4.) We would expect that with the collection of a first generation Church the demand would be placed upon adults to “repent and be baptized.” However, Acts 2 makes it clear, as heard through the ears of a covenantal non-Anabaptist people, that the promises were to “you and to your children.” So, yes, the New Testament record, in gathering a first generation Church would emphasize the necessity for adults to “repent and be baptized” but that does not negate that those same adults, as well as the subsequent generations would have understood that their children as belonging to them belonged to God and so should receive the sign and seal of the covenant.
