42 In the modern era, the idea of the Last Judgement has faded into the background: Christian faith has been individualized and primarily oriented towards the salvation of the believer's own soul, while reflection on world history is largely dominated by the idea of progress. The fundamental content of awaiting a final Judgement, however, has not disappeared: it has simply taken on a totally different form. The atheism of the nineteenth and twentieth centuries is—in its origins and aims—a type of moralism: a protest against the injustices of the world and of world history. A world marked by so much injustice, innocent suffering, and cynicism of power cannot be the work of a good God. A God with responsibility for such a world would not be a just God, much less a good God. It is for the sake of morality that this God has to be contested. Since there is no God to create justice, it seems man himself is now called to establish justice. If in the face of this world's suffering, protest against God is understandable, the claim that humanity can and must do what no God actually does or is able to do is both presumptuous and intrinsically false. It is no accident that this idea has led to the greatest forms of cruelty and violations of justice; rather, it is grounded in the intrinsic falsity of the claim. A world which has to create its own justice is a world without hope. No one and nothing can answer for centuries of suffering. No one and nothing can guarantee that the cynicism of power—whatever beguiling ideological mask it adopts—will cease to dominate the world. This is why the great thinkers of the Frankfurt School, Max Horkheimer and Theodor W. Adorno, were equally critical of atheism and theism. Horkheimer radically excluded the possibility of ever finding a this-worldly substitute for God, while at the same time he rejected the image of a good and just God. In an extreme radicalization of the Old Testament prohibition of images, he speaks of a “longing for the totally Other” that remains inaccessible—a cry of yearning directed at world history. Adorno also firmly upheld this total rejection of images, which naturally meant the exclusion of any “image” of a loving God. On the other hand, he also constantly emphasized this “negative” dialectic and asserted that justice —true justice—would require a world “where not only present suffering would be wiped out, but also that which is irrevocably past would be undone”. This, would mean, however—to express it with positive and hence, for him, inadequate symbols—that there can be no justice without a resurrection of the dead. Yet this would have to involve “the resurrection of the flesh, something that is totally foreign to idealism and the realm of Absolute spirit”.
