Biblical Theology and Systematic Theology Considered Again

We will take as our starting point the following well-known quotation from Vos’s Biblical Theology:

The fact is that Biblical Theology just as much as Systematic Theology makes the material undergo a transformation. the sole difference is in the principle on which the transformation is conducted. In the case of Biblical Theology this is historical, in the case of Systematic Theology it is of a logical nature. Each of these two is necessary, and there is no occasion for a sense of superiority in either. (Biblical Theology, p. 14).

What can plausibly be laid against this claim by Vos is that the Bible is more inherently historical than logical, and that therefore BT is a “better fit” than ST. Even if didactic portions of Scripture are acknowledged to be less historically organized than other portions (Proverbs comes to mind), the historical framework of the Bible still remains in place. What I wish to do is to answer this plausible objection.

Firstly, it is clear that certain portions of Scripture are less historically organized than others. Proverbs, for instance, is better organized topically than historically. It has been shown in some recent scholarship that Proverbs presupposes the historical covenants. Fair enough. I agree that Proverbs is not “secular” wisdom, but holy wisdom, however much certain parts of it might resemble Amenemope. However, the organization of the text itself is still better done topically. This means that making Proverbs undergo an historical transformation in order to fit BT categories would require a greater transformation than an ST treatment would.

What this means for the broader question is just this: BT might be a smaller transformation of historically organized texts than an ST treatment would represent. However, an ST treatment of other texts, like Proverbs, would represent a smaller transformation than BT would. In other words, genre differences are a factor in how much transformation a given text would undergo in BT or ST guise.

Secondly, ST is not somehow incapable of assimilating historical change into a logical locus. Surely, ST treats the locus of covenant theology with reference to the historical progression of the various iterations of the covenants! As Dr. Richard Gaffin once said, ST is like a plot analysis of a novel, and BT is like a plot summary. BT cannot ignore the logical relations entirely. Nor can ST ignore the historical progression of revelation. Each has to take the other into account. As a result, BT and ST must be completely interdependent, even while they can be distinguished.
