I. Inner Evolution and Outer Possibilities for Development

False Christs will appear in this age, in which humanity is to see the true Christ in the etheric body. But anthroposophists are called upon to be able to distinguish between the spiritual and the material and to be firmly armed against all assertions, wherever they may come from, that a Christ would come in the flesh. Anthroposophists are called upon to recognize that this would be materialism, the worst tempter, which could arise at one of the most important events in the development of humanity, at the event that we call the return of Christ, and at which it will have to be proven whether people have already come so far as not just to speak of the spirit, but to be able to recognize the nature of the spirit as something higher than the nature of matter.
