"Let then every Christian take warning against the agitations of the socialists and communists. Their aim is a Fata Morgana, i.e., a brilliant airy appearance, like a fairy castle. The pilgrim makes one more effort to reach this castle. He finally reaches the place where the bewitching atmospheric appearance was seen. And behold, it is gone, and the deceived wanderer is now surrounded with a darkness and trouble all the more dreary."
- C.F.W. Walther, 1879.
