I. The Relationship of Anthroposophy to Religious Life
You see, the Greeks had a great advantage compared to the oriental world, they could to draw together their innermost nature so to speak. From within themselves they could draw a content, but this content could first only attach as filled with fantasy, imagination. However, there was something the Greeks didn't know. They had brought the development of humanity to internalisation but didn't attach it to the inner life. The internalisation and the hardening continued in the Roman times and beyond, and man had to learn—today still we need to learn to understand—how one can attach what is within, what permeates this inner being. The Greeks could think about their gods in grandiose fantasy images but what the Greek could not do, was to pray. The prayer only cam about later and for prayer the possibility had to be found of connecting the one praying, to reality. To this we must connect those times in which prayer was not merely spoken, not merely thought or not merely felt, but in which prayer became one with the sacramental ritual. Then again Catholicism knows quite well why they don't separate themselves from ritual, from the sacrificial act, from the central sacrifice of the mass.
