Book excerpt: Over half of Americans believe in a literal heaven, in a literal hell. Most people who hold these beliefs are Christian and assume they are the age-old teachings of the Bible. Ehrman shows that eternal rewards and punishments are found nowhere in the Old Testament, and are not what Jesus or his disciples taught. He recounts the long history of the afterlife, ranging from The Epic of Gilgamesh up to the writings of Augustine, focusing especially on the teachings of Jesus and his early followers. Ehrman shows that competing views were intimately connected with the social, cultural, and historical worlds out of which they emerged. -- adapted from jacket
