Baptism strikes me as a good instance of how we all need to have a rich and deep theology. To answer the question 'Should I baptize my child?' will require some pretty serious considerations of the nature of faith and salvation and church and covenant and OT/NT relations etc. I hazard to suggest that those who say "You have your theology, I just have my bible" simply couldn't come up with an argument for paedo or credo baptism without some kind of systematic considerations.
You might have guessed (being an Anglican and a covenant theologian) that I believe in baptizing infants in Christian households. I digress into this issue here in a sermon on Genesis 17. To put it briefly I believe that OT saints were to circumcize all in their households (on the 8th day) as an entrance into the covenant community. They were meant to grow up from within that covenant community as full members. But for that very reason they were urged to inwardly own the outward sign of their belonging and to have a circumcized heart (Deut 10:16; 30:6; Jer 4:4). Without this they forgo all the benefits of the outward sign and will in the end be treated as not simply uncircumcised but as covenant-breakers - a fearful position to be in. In this sense I believe in baptizing infants in Christian households. I do think Col 2:11-12 makes the link between circumcision and baptism though not directly but through Christ. I believe it is the NT sign of belonging to the covenant people. In this sense it is appropriate to baptize youngsters, to proclaim the gospel promises over them, to treat them as full members of the church and to urge them as they grow up to own the meaning of their baptism inwardly (a baptism of the heart). That kinda thing.
Anyway, there's a guy in our congregation who wants to talk through who we should baptize. Anyone got any suggestions for some good books we could look at? (From any perspective)
