"But for the coming of Christianity, who knows how the history of Europe would have developed? Rome would have conquered all Europe, and the onrush of the Huns would have been broken on the legions. It was Christianity that brought about the fall of Rome—not the Germans or the Huns. What Bolshevism is achieving to-day on the materialist and technical level, Christianity had achieved on the metaphysical level."
