Today is the birthday of Rudolf Bultmann, a great New Testament scholar and thinker about the Christian faith. As with most great thinkers, he had ideas that have not stood the test of time. But so much of what he proposed is insightful that he is still very much worth reading. Conservatives have probably heard him criticized, and never read him for themselves, and so will not realize how much of every kind of New Testament scholarship and thinking about the nature of Christianity has been shaped by his contribution, and by discussions that he helped spark.
Finally, Chris Ayers noted that it is not atheists, nor even liberal Christians, who first noticed absurdities in the Bible. It can be traced back to Augustine, and even earlier.
