Dogmatics is the testing of Church doctrine and proclamation, - Karl Barth

Frederick the Great (1712-1786) once asked his personal physician, Dr. Zimmermann, "Can you name me a single proof of the existence of God?" Zimmermann replied, "Your Majesty, the Jews!" By that he meant that if one wanted to ask for a proof of God, for something visible and tangible, that no one could contest, which is unfolded before the eyes of all men, then we should have to turn to the Jews. Quite simply, there they are to the present day. Hundreds of little nations in the Near East... have dissolved and disappeared in the huge sea of nations; [only] this one tiny nation has maintained itself.... If the question of a proof of God is raised, one need merely point to this simple historical fact. For in the person of the Jew there stands before our eyes the witness of God's covenant with Abraham, Isaac, and Jacob, and in that way with us all. Even one who does not understand Holy Scripture can see this reminder.

Godlessness is not… a possibility, but an ontological impossibility for man. Man is not without, but with God. This is not to say, of course, that godless men do not exist. Sin is undoubtedly committed and exists. Yet sin itself is not a possibility but an ontological impossibility for man. We are actually with Jesus, i.e., with God. this means that our being does not include but excludes sin. To be in sin, in godlessness, is a mode of being contrary to our humanity. For the man who is with Jesus… is with God. If he denies God, he denies himself… He chooses his own impossibility

In the political sphere the Church will always and in all circumstances be interested primarily in human beings and not in some abstract cause or other, whether it be anonymous capital or the state as such (the functioning of its departments!) or the honour of the nation or the progress of civilisation or culture or the idea, however conceived, of the historical development of the human race.
