43. Christians likewise can and must constantly learn from the strict rejection of images that is contained in God's first commandment (cf. Ex 20:4). The truth of negative theology was highlighted by the Fourth Lateran Council, which explicitly stated that however great the similarity that may be established between Creator and creature, the dissimilarity between them is always greater. In any case, for the believer the rejection of images cannot be carried so far that one ends up, as Horkheimer and Adorno would like, by saying “no” to both theses—theism and atheism.
For this reason, faith in the Last Judgement is first and foremost hope—the need for which was made abundantly clear in the upheavals of recent centuries. I am convinced that the question of justice constitutes the essential argument, or in any case the strongest argument, in favour of faith in eternal life. The purely individual need for a fulfilment that is denied to us in this life, for an everlasting love that we await, is certainly an important motive for believing that man was made for eternity; but only in connection with the impossibility that the injustice of history should be the final word does the necessity for Christ's return and for new life become fully convincing.
