Of course it is appropriate to characterize the "narrative/historical approach" as a method of critical discourse, but I’m not at all convinced that we can and should separate this from theology. mars-hill writes,

Of course, our reading affects our theology but I can see a distance between the two disciplines (critical reading and developing theology).

It seems to me that our reading is our theology. Or theology is our reading (and rereading). I think that is the larger thrust of the whole narrative approach, which refuses to see theology as a science abstracted from context.

Does that make any sense?
