Hitler Speech-The Basis of Nationhood-Nuremberg, September 16, 1935
Without these models and without the common ground of union which was found in the spiritual teachings of Christianity, the formation of a German State at that era cannot be imagined. Were it not for those factors the destiny of Europe and indeed the rest of the world, as far as concerns the white races, was then unthinkable and even today we could not picture it to ourselves.In contrast to the strongly divergent tendencies of the various German tribes, Christianity supplied a unifying principle which organised them in the first community in which they were in anyway conscious of a common destiny and which also had an outward and visible form for them. Thus it furnished a religious and philosophical basis on which it was possible to organise those tribes into a political State.
