Rev. Tom Honey maybe?
I saw Tom Honey's TED talk and thought it was a really liberal and interesting speech to be coming from a theist. You may not agree with the suggestion since he's not exactly seen all over the media or anything, but when I think of the Richard Dawkins discussion with the Bishop of Oxford, I can't help but wonder if Rev. Tom Honey wouldn't make for an interesting interview with a theist.
Of course, judging by his video, he may just end up saying "I don't know" to a lot of questions, but he seemed worth a suggestion.
A place common to all will be maintained by none. A religion common to all is perhaps not much different.
