Is "Christian Jurisprudence" Possible?

I participated this weekend in the kick-off session of a new research project sponsored by the Law and Religion Program at the Emory School of Law.  The project involves several dozen legal scholars, theologians, and ethicists from the Roman Catholic, Protestant, and Orthodox traditions, and aims at producing a body of work that "retrieves" and "re-engages" "Christian Jurisprudence."  Several of the participating scholars, though (Professor Milner Ball, in particular), expressed doubts about the very possibility of "Christian Jurisprudence" -- about, as I understood it, both the possibility of "jurisprudence" being "Christian" and about the possibility that "Christianity" contains "jurisprudence" -- and these doubts prompted fascinating discussions that, I expect, will continue throughout the project's life.   

Given my own involvement in a blog "dedicated to the development of Catholic legal theory," I suppose I have a stake of sorts in the possibility of "Christian Jurisprudence."  Any thoughts?
