Michener seems determined to undermine the credibility of all religions by suggesting they originated from primitive paganism and early humans' efforts to understand and placate their hostile surroundings. While he does acknowledge some of the positive aspects of each diverse faith, on the whole, he focuses on and highlights the negatives within all religions.
He condemns paganism for the practice of child sacrifice. Judaism comes under fire for what he views as its outdated and cruel marriage laws, as well as its excessive emphasis on the minutiae of religious law. Islam is criticized for its barbaric forced conversions, and Christianity is faulted for its internal feuds over religious doctrine, as well as its murderous crusades and inquisitions.
Subsequently, he situates all of this within the context of modern-day Israel's internal struggle to define itself either as a Jewish state or as a state for Jews, and its conflict with its Arab neighbors and minority populations.
