Cullmann on Baptism

I have been re-reading Oscar Cullmann's brilliant Baptism in the New Testament again. He concludes his little, but influential, book like this:

In the New Testament it is certainly proved that Baptism is applied to adult Jews and heathen who come over to Christianity. Proof of infant Baptism is at best indirectly demonstrable from observable indications. On the other hand, infant Baptism is in every detail congruous with the doctrine of Baptism, in the following ways:

1. in so far as Christ in his death and resurrection procures for all men and independent of them a general Baptism [i.e. judgment overcome with new life];
2. in so far as God in the entirely sovereign act of grace of Church Baptism permits the person baptised, through an incorporation into the fellowship of the Body of Christ at a specific place, to take part in that once-for-all saving event;
3. in so far as faith as response to this grace is decisive;
4. in so far as Baptism in its nature is the completion of circumcision and of the proselyte baptism connected, with it.

From these final conclusions, both adult and infant Baptism are to be regarded as equally biblical. (p.70)

Wonderfully this book is now on the internet here (pdf). Go read it if you can.
