The Mystery of the Trinity and The Mission of the Spirit

The lectures were given by Rudolf Steiner to audiences familiar with the general background and terminology of his anthroposophical teaching. It should be remembered that in his autobiography, The Course of My Life, he emphasizes the distinction between his written works on the one hand, and on the other, reports of lecture that were given as oral communications and were not originally intended for print. For an intelligent appreciation of the lectures it should be borne in mind that certain premises were taken for granted when the words were spoken. "These premises," Rudolf Steiner writes, "include at the very least the anthroposophical knowledge of Man and of the Cosmos in its spiritual essence; also what may be called 'anthroposophical history, ' told as an outcome of research into the spiritual world."
