When human affairs are so ordered that there is no recognition of God,
there is a belittling of man. That is why, in the final analysis,
worship and law cannot be completely separated from each other. God has a
right to a response from man, to man himself, and where that right of
God totally disappears, the order of law among men is dissolved, because
there is no cornerstone to keep the whole structure together.
