Christians realize that whenever any system is established in this world, however noble and lofty its aims and however much it may be inspired by the will to good, it is only possible through sheer power, and that in the process of setting up any secular order, whether nationally or internationally, human beings are sacrificed and crushed. The prosperity of some is purchased only at the expense of the suffering and indeed often the destruction of others. That is the way things inevitably go in this world. But Christians refuse to be satisfied with this inevitability; they feel as a painful burden the sorrow and the tears of those to whom violence is done. And if this is the unalterable way of things in this world, if the way of secular government is a way which always leads through blood and tears, then we conclude that this very fact is a sign that the dominion of men is never the dominion of God nor can it ever lead to the dominion of God
— Rudolf Bultmann, in a sermon delivered on Advent III, Dec. 11th 1938 - just over one month after the violent attacks on Jews on Kristallnacht.
