Both streams had come down from the far past. On the one side there was the heathen stream which was fundamentally a nature wisdom. All natural creatures were seen to be inhabited by elemental spirits, demonic spirits, those very demonic spirits who, in the Gospels, are said to have rebelled when Christ came amongst mankind, because they knew that their rule was at an end. Human beings failed to recognize Christ, but the demons recognized him. They knew that he would now take possession of human hearts and human souls and that they would have to withdraw. But for a long time they continued to play a role in the minds and hearts of human beings as well as in their search for knowledge. Heathen consciousness, which sought the demonic, elemental spirits in all creatures in the old way, continued to play a role for a long time. It wrestled with that other form of knowledge which now sought in all earthly things the substance of Christ that had united with the earth through the Mystery of Golgotha.
This heathen stream—a nature wisdom, a nature Sophia—saw the spirit everywhere in nature and could therefore also look at man as a natural creature who was filled with spirit, just as all nature was filled with spirit. In its purest, most beautiful form we find it in ancient Greece, especially in Greek art, which shows us how the spirit weaves through human life in the form of destiny, just as the natural laws weave through nature. We may sometimes recoil from what we find in Greek tragedies. But on the other hand we can have the feeling that the Greeks sensed not only the abstract laws of nature, as we do today, but also the working of divine, spiritual beings in all plants, all stones, all animals, and therefore also in man. The rigid necessity of natural laws was shaped into destiny in the way we find it depicted, for instance, in the drama of Oedipus. Here is an intimate relationship between the spiritual existence of nature and the spiritual existence of man. That is why freedom and also human conscience as yet play no part in these dramas. Inner necessity, destiny, rules within man, just as the laws of nature rule the natural world.
This is the one stream as it appears in more recent times. The other is the Jewish stream of the Old Testament. This stream possesses no nature wisdom. As regards nature, it merely looks at what is physically visible through the senses. It turns its attention upwards to the primal source of moral values which lies in the world between death and a new birth, taking no account of the side of man which belongs to nature. For the Old Testament there is no nature, but only obedience to divine commandments. In the Old Testament view, not natural law, but Jahve's will governs events. What resounds from the Old Testament is imageless. In a way it is abstract. But setting aside Philo of Alexandria, who makes everything allegorical, we discern behind this abstract aspect, Jahve, the ruler who fills this abstraction with a supersensibly focused, idealized, generalized human nature. Like a human ruler, Jahve himself is in all the commandments which he sends down to earth. This Old Testament stream directs its vision exclusively to the world of moral values; it absolutely shies away from looking at the externally sense-perceptible aspect of the world. While the heathen view saw divine spiritual beings everywhere, the god of the Jews is the One God. The Old Testament Jew is a monotheist His god, Jahve, is the One God, because he can only take account of man as a unity: You must believe in the One God, and you shall not depict this One God in any earthly manner, not in an idol, not even in a word. The name of God may only be spoken by initiates on certain solemn occasions. You must not take the name of your God in vain.
Everything points to what cannot be seen, to what cannot come to expression in nature, to what can only be thought. But behind the thought in the Old Testament there is still the living nature of Jahve. This disappears in the allegories of Philo of Alexandria.
Then came the early Christian struggles—right on into the fifteenth, sixteenth, seventeenth centuries—to reach a harmony between what can be seen as the spirit in external nature and what can be experienced as the divine when we look at our own moral world, our own human soul. In theory the matter seems simple. But in fact the quest for harmony, between seeing the spirit in external nature and guiding the soul upwards to the spiritual world out of which Christ Jesus had descended, was an immense struggle. Christianity came over from Asia and took hold of the Greek and Roman world. In the later centuries of the Middle Ages we see the struggle taking place most strongly in those parts of Europe, which had retained much of their primeval vitality. In ancient Greece the old heathen element was so strong that although Christianity passed through Greek culture and assimilated many Greek expressions on the way, it could not take root there. Only Gnosis, the spiritual view of Christianity, was able to take root in Greece.
