When the Romans became Christian, the old pagan world went down into the unconscious, into oblivion.
There, there were already the old nature spirits. Then the old gods go down into the depths of the mountains.
Wotan, for example, who moves in storms at night. The recognized gods of the day go down into the night.
There they civilize the unconscious; they will gradually domesticate the unconscious.
These attempts at individuation are sending missionaries to the unconscious, to baptize the heathen world of the unconscious.
We do this same job on ourselves.
This Christianizing of the unconscious is observable through analysis.
The unconscious becomes more manageable. In time we shall have the whole Christian church in our unconscious. ~Carl Jung, Cornwall Seminar, Page 25.
