Several days ago, Eric had emailed Jamie Smith (aka known as James K.A. Smith, author of Introducing Radical Orthodoxy (which I am reading) and told him about the discussions Eric and I had been having. Jamie offered to answer 2 or 3 questions if we wanted to pose some. So , the comments section of this post, we did so, and Eric sent them off. The reply came, and Eric posted it here, and several comments there have ensued (including me).
Jamie Smith also posted about it on his blog here
The dialogue on this has been great.
