Imagine for a moment that one of your friends writes you a 20 page letter passionately wanting to share his excitement about a new teacher. This letter has only one topic; your friend's new teacher. Yet by the end of his letter, after all 20 pages of it, you still don't know one thing about his teacher. Paul presents the central figure of his theology in just this way. For those of us not lost in delusional worlds it might seem impossible to imagine how Paul could avoid telling even one story or parable or fail to note one physical trait or personal quality of Jesus. But Paul's lack of interest in or even curiousity about the life of this Jesus does fit a characteristic pattern of paranoid delusions.
On a totally unrelated note I want to mention one thing that I've always paid attention to. Swearing. I have a theory. Some people got it. Some don't. These guys can swear. So can this guy (yes, the link is right. Give it 20 seconds. Listen a couple of times to fully appreciate). Others sound totally unnatural. I was raised in a very evangelical family and never developed my swearing capacity. Now as an adult that doesn't feel like there's a huge moral problem with it I still find that it's difficult for me to do it without sounding like a nerd. Seems to me Richard has the same problem. He seems to swear occasionally perhaps to elicit laughter but to me it's seems unnatural for him.
Anyway, he's done some great work and I've learned a lot from him.
