Ray is a richful character.
He preached a interesting and very loose interpretation of christianity, not found in any specific denomination.
Sometimes I think he was a kind of atheist because he discussed fallacies and used them as a mean to detect false teachings. No religious person use fallacy detection as a method because if you follow this method you'll reject the very christianity as false.
He was a very interesting person. It would be great to see a documentary about him in BBC style.
