Credo vs. paedobaptism...
Is this blessing then on the circumcised, or on the uncircumcised also? For we say, “faith was credited to Abraham as righteousness." How then was it credited? While he was circumcised, or uncircumcised?
Not while circumcised, but while uncircumcised; and he received the sign of circumcision, a seal of the righteousness of the faith which he had while uncircumcised, so that he might be the father of all who believe without being circumcised, that righteousness might be credited to them, and the father of circumcision to those who not only are of the circumcision, but who also follow in the steps of the faith of our father Abraham which he had while uncircumcised. (Romans 4:9-12)
One reader commented under another post: "Another interesting argument I came across recently from John Piper: When the New Testament church debated in Acts 15 whether circumcision should still be required of believers as part of becoming a Christian, it is astonishing that not once in that entire debate did anyone say anything about baptism standing in the place of circumcision. If baptism is the simple replacement of circumcision as a sign of the new covenant, and thus valid for children as well as for adults, as circumcision was, surely this would have been the time to develop the argument and so show that circumcision was no longer necessary. But it is not even mentioned."
My response: Weak argument although I'll take John Piper over John MacArthur any day when it comes to arguments against paedobaptism...
