I'm a bit slow at the moment. My entry at the Daily Episcopalian at Episcopal Café can be read. Being a bit late, I see some comments and rather like the first comment (scroll down) and can respond myself.
Of course the science is itself a narrative but it is a narrative based on maths and experiment and produces a working explanation for how the world operates, and really, theology, which explains nothing in such a sense, can be based on dealing with that and re-employing its own concepts.
Obviously I think Murdoch Matthew's comment further down has hit the nail on the head. I'm sorry not to respond there: it is that every time I try to enter a comment I get nowhere.
