Ira Glass had a This American Life episode a number of weeks back, called “The Ten Commandments”, with a chaplain that serves the U.S. Army. I appreciated what he had to say though I disagreed with him a lot (as did Ira Glass). This is a ‘bonus’ audio clip that was released after the episode aired; I thought it was interesting. They discuss the idea of Christianity being peace focused and what that means for a chaplain that goes into battle with an army.
I especially like what he says about questions and the most effective responses to the ones that you don’t know the answers to.
