To me, who first approached Christianity from a delighted interest in, and reverence for, the best pagan imagination, who loved Balder before Christ and Plato before St. Augustine, the anthropological argument against Christianity has never been formidable. On the contrary, I could not believe Christianity if I were forced to say that there were a thousand religions in the world of which 999 were pure nonsense and the thousandth (fortunately) true. My conversion, very largely, depended on recognizing Christianity as the completion, the actualization, the entelechy, of something that had never been wholly absent from the mind of man.1
I couldn't believe that nine-hundred and ninety-nine religions were completely false and the remaining one true. In reality, Christianity is primarily the fulfillment of the Jewish religion, but also the fulfillment of what was vaguely hinted in all the religions at their best. What was vaguely seen in them all comes into focus in Christianity.2
