If you hold to believer's baptism (credo baptism), you would do well to at least appreciate the fact that your Protestant infant baptist (paedobaptist) brothers and sisters in Christ are working with Scripture to come to their position.
In Acts, households were baptized (Acts 11:14; 16:15, 33; 18:8; 1 Cor 1:16). Presumably, this would include the children of new the believers.
There is continuity between the OT rite of circumcision and the NT rite of baptism (this is suggested by Col 2:11-12). In the same way that infants were circumcised in the OT, so infants are to be baptized in the NT.
The above two factors can be explained by means of an understanding of the covenant between God and his people. The covenant extends to children (Gen 17:7). Not everyone in the visible covenant family (those who are baptized as infants) is part of the true covenant family (see Rom 9:6b).
This view emphasizes continuity between the OT and the NT. This view is often based on the Abrahamic Covenant or the notion of a single Covenant of Grace that encompasses both OT and NT times.
There is other evidence in Scripture that parents' belief extends to their children (Acts 2:38-39; 16:31; 1 Cor 7:14).
If you hold to infant baptism (paedobaptism), you would do well to at least appreciate the fact that your credobaptist (those holding to believer's baptism) brothers and sisters in Christ are working with Scripture to come to their position.
The pattern in the New Testament is first, repentance/faith, and, subsequently, baptism (Matt 28:19; Acts 2:41; Acts 8:12; 9:18; 10:47-48; 16:14-15; 18:8; ). Thus, no one should be baptized until after they personally come to repentance and faith themselves.
The New Testament fulfillment of circumcision is not baptism, but circumcision of the heart, that is, the New Birth (Rom 2:29).
No where in the Bible are we told to baptize our infant children.
