" It is the cultures of the great world religions which have shaped the course of civilization, and these possess a kind of supercultural position. (...) The three great religions of the East - Confucianism, Brahmanism and Buddhism - and the three world religions in the West - Judaism, Christianity and Islam - have been the great unifying factors in the civilization of the world. They are, as it were, the spiritual highways, which have led mankind through history from remote antiquity down to modern times. (...) In the past all these world religions with the exception of Judaism have been what I have termed supercultures - common forms of faith and moral order which embraced and united large numbers of previously existing cultures with their own languages and histories. "
