Long ago I wrote an article trying to show the fundamental contradiction between Christianity and Communism. I received a long letter from a fine, devoted Protestant from southern France who believed I was utterly mistaken. He found an extraordinary harmony between the Communist and Christian ethic. The Communist ethic, including its tactics and strategy, expressed precisely what was being lived out in Christianity. What proof did he offer? He recommended I read the essential book by Liu Ch'ao-Chi, How to Be a Good Communist. Unfortunately, this devoted Protestant was writing early in 1966, a few months before the cultural revolution, in which Liu became public enemy number one, and his book was considered to be nothing but error!
