I've recommended The Flame Alphabet by Ben Marcus on many occasions, but it seems very appropriate to a discussion of religious belief or lack thereof. In this apocalyptic novel, the voices of Jewish children have become toxic. Eventually language itself becomes generally deadly. The notion of religion as any sort of consolation in this world is seen as a comical delusion: Jews in the story practice by retreating into huts in the woods, where they pick up secret broadcasts by their renegade rabbi. However, it's evident that the content of these broadcasts is deliberately incoherent and unreliable, and that nothing useful can really be understood about man's relationship to the divine or the eternal. The importance of ritual and belief appear to be directly proportional to their utter futility and incomprehensibility.
