If it is true that absolute atheism is primarily the fruit and condemnation of practical atheism, and its reflected image in the mirror of divine wrath, then it must be said that the cardinal prerequisite for getting rid of absolute atheism is first to get rid of practical atheism. A decorative Christianity is henceforth not enough. A living Christianity is necessary to the world. Faith must be actual, practical, existential faith. To believe in God must mean to live in such a manner that life could not possibly be lived if God did not exist. For the practical believer, gospel justice, gospel attentiveness to everything human must inspire not only the deeds of the saints, but the structure and institutions of common life, and must penetrate to the depths of terrestrial existence.
