Ben! I had no idea I was a closet Baptist...
(For any who don't know, Ben was most excellently trained at SBTS, whose faculty he admires, and he has many attractive and well-spoken friends from those days)
One might say things this way: RefBaptist and Presbyterian take different routes, and arrive at basically the same soteriological destination, that is to say holding to pretty much the same core doctrine on matters of Christ and salvation--what must be believed in order to be saved, and what "angle" is best to view those things (the best seats in the house).
Still, respecting the matter of which route, clearly it is not a matter of indifference. The hermeneutical question "how to read the Bible" plays a significant role in the different conclusions both sides reach. Failure to appreciate the reality that formal agreement on the significance of Sola scriptura is not the same as how one reads the Scripture, is a major reason why I do not "cheer" a person "switching sides" (so to speak) on baptism, without coming to grips with all such a conversion entails.
Instead, I'm crossing my fingers, wondering if such an individual is thinking as deeply as he should, or if he will end up confused, disappointed, regretful, reversed, or on his way to some other theological (or even religious) camp. It has happened before, right before our eyes.
So my chief contribution to this thread is an attempt to make it clear that the ordinary differences between the Baptist and the Reformed are NOT cosmetic, even when we speak about the self-conscious, covenantal/confessional RefBapt contingent. The latter obviously have major affinity with the non-baptist stream of this tradition, and I thank God for them.
But if it was an "easy" matter to convince one from the other persuasion, the division would never have continued for hundreds of years.
