Geerhardus Vos gave a lot of ground to the Baptists (some would argue too much). He insisted that “baptizo” means “immerse,” although he goes on to argue that the immersion is secondary, and that washing is primary. For Vos, the immersion is incidental to the meaning of the word. The substance of baptism can, for Vos, be accomplished in another way. But the most fascinating thing about his argument against immersion is his advocation of catholicity (Reformed Dogmatics, volume 5, p. 125):
To what, finally, can one still appeal against the Baptists? To the universal character of Christianity. Christianity is catholic, that is, intended for all times and places. That must come out in its sacraments too. Hence, the signs in these sacraments are such as are to be found everywhere: water, bread, wine-the most common products of nature that can be kept everywhere. But the same thing will also have to apply to their manner of use. Immersion is something that is sometimes feasible in Middle Eastern lands, but then again in many regions, not. If Christianity is thus bound to something like this, then in this respect it is the same as Islam, which obligates all its adherents to a pilgrimage to Mecca. But Islam is then also particularistic; Christianity is universal, catholic, intended for all times, countries, circumstances, and conditions.
I had not thought of using the catholicity of Christianity as an argument against immersion before. So I thought I would throw it out there for the readers. What do you think of this argument?
