Marcus Maher reviews a new book called Three Views on Baptism. It basically covers the two main views of baptism found among Protestants along with a third view by Anthony Lane that is very close to what my own congregation does, and I've hardly ever seen anyone argue for such a view in print (which I think is the best practice, for the record).
The idea is that scripture isn't clear enough on the issue of baptism to justify a congregation requiring either believer's baptism or infant baptism. Instead, a congregation should leave it to the parents to decide whether they will (a) baptize their infant in anticipation of a later confirmation or (b) dedicate in anticipation of a later baptism (with pretty much the same content expressed at whichever one ends up occurring).
I happen to be of the view that each practice is functionally equivalent to the other practice. One of them conceptualizes it in a more biblical way, but the other does the same thing under a less-biblical way of describing it and conceiving of it.
As I commented on Marcus' post, I think there are two issues going on here, one of which isn't remotely settled by Lane's approach. Here are two separate questions:
1. What should a church allow in terms of its practice (only infant, only believer's, leave it to the conscience of the parents)?
2. What should a parent do (which might involve how parents choose a congregation to be members of or mighty involve choosing what to do in a dual-practice congregation)?
Even if you answer the first question with dual-practice (as I would), you still need an answer to the second question. I belong to a dual-practice congregation, and I think they made the right choice to allow both. But I think the scriptures do favor believer's baptism. Someone else might disagree with me (as several members of my congregation do, including one of the three elders). But I don't think that disagreement is grounds for division, which is why I favor the dual-practice approach.
What I don't think Lane really answers, though, is the second question. Favoring dual-practice in a congregation doesn't mean not taking a view on which to do when it comes time to decide between them, and it seemed to me from the review that Lane doesn't take a stance on that question. He thus hasn't answered the main question the other two authors are debating in the book, which is a little strange if the book is supposed to cover three views on the same question.
