On the one hand we have the fact that Christ is the Sun Spirit who united Himself with the life of the Earth through the Mystery of Golgotha. You will find the most detailed account of this in the lecture-courses entitled The Gospel of St. John — in its Relation to the Other Three Gospels, particularly to the Gospel of St. Luke, given in Kassel, and From Jesus to Christ. And now we have heard of the other fact, namely that all external progress on Earth from one culture-epoch to the next is dependent upon influences from beyond the Saturn region. A question arises here: Progress on Earth from one culture-epoch to another is dependent upon influences connected with a world beyond the Saturn sphere — a world altogether different from the one where progress is brought about by the stream of spirituality that flows through the evolution of humanity, that approached humanity in ancient times, has its centre of gravity in the Mystery of Golgotha and thereafter took its course in the way often described. How do these two facts harmonise? The truth is that they harmonise completely.
