There might be some fruitful ground here for answering both the Baptists and the Federal Vision folks, who both have the same error in treating the NT sacraments as working the same way. Indeed, as a friend of mine once said, the problem of the FV’ers in their sacramental theology is not that they have over-reacted to Baptistic theology in every respect, but that they have not thrown off the problems of Baptistic thinking enough. It must be born in mind that most FV’ers were Baptists before they became FV.

One of the most controversial aspects of sacramental theology is the relationship between the Old Testament sacraments of Passover and circumcision (and some would even dispute that they are sacraments!) and the New Testament sacraments of baptism and the Lord’s Supper. I am not going to treat this subject exhaustively at all. There are just two points that I wish to make, fueled by Vos’s discussions in volume 5 of Reformed Dogmatics, pp. 103-104.

The first point that Vos makes is that the Old Testament sacraments are types of Christ, not of the New Testament sacraments. There is, indeed, a correspondence between the two sets of sacraments. However, there is not a typological relationship between the two (p. 104).

The second issue is something that has bothered me for a while. Why is it that the recipients of the Passover have in an important way narrowed (those who can discern the Lord’s body versus all children in the Passover, thus making an age differene), while the recipients of baptism have broadened (all children and believing adults on their conversion, not just the male children)? Of course, it is merely a Baptistic assumption that the New Testament sacraments must be alike in how they work. There are several important differences between baptism and the Lord’s Supper, which we will not get into here. But why has the change to New Testament sacraments resulted in a seemingly opposite scope for circumcision giving way to baptism, and Passover giving way to the Lord’s Supper? Vos offers an explanation I have not seen elsewhere (though I would be surprised if this explanation originated with him: anyone know of sources from which this could have come?):

[I]n Israel the sacraments, besides their significance for the covenant of grace, also had a national aspect, from which a difference in practice arose between them and the New Testament sacraments on a few points. For us, one comes to the table of the Lord only after one has learned to discern the body of Christ. In Israel the children also ate the Passover. This was because the Passover together with its covenantal significance had national significance. The same is true for circumcision. Baptism in the New Testament is administered to both sexes of the children of believers. In the Old Testament, circumcision was only for infant boys. Indeed, in the national life of Israel only the men counted and represented the women, and this also had to come to light outwardly (p. 103).

Indeed, as a friend of mine once said, the problem of the FV’ers in their sacramental theology is not that they have over-reacted to Baptistic theology in every respect, but that they have not thrown off the problems of Baptistic thinking enough.
