Reveals why some people in Judea and then in the Roman and Greek worlds embraced a new approach to the forces and powers in their daily lives. Knapp traces the emergence of Christianity from its stirrings in the eastern Mediterranean, where Jewish monotheism coexisted with polytheism and prayer mixed with magic. In a time receptive to prophetic messages and supernatural interventions, Jesus of Nazareth convinced people to change their beliefs by showing, through miracles, his direct connection to god-like power. The miracle of the Resurrection solidified Jesus's supernatural credentials. After his death, followers continued to use miracles and magic to spread Jesus's message of reward for the righteous in this life and immortality in the next. Many Jews and polytheists strongly opposed the budding movement but despite major setbacks Christianity proved resilient and adaptable. It survived long enough to be saved by a second miracle, the conversion of Emperor Constantine. Hand in hand with empire, Christianity began its long march through history.
