In broad outline and in detail, the life of Jesus as portrayed in the gospels corresponds to the worldwide Mythic Hero Archetype in which a divine hero's birth is supernaturally predicted and conceived, the infant hero escapes attempts to kill him, demonstrates his precocious wisdom already as a child, receives a divine commission, defeats demons, wins acclaim, is hailed as king, then betrayed, losing popular favor, executed, often on a hilltop, and is vindicated and taken up to heaven.
The piety of "having a personal relationship with Christ" ... is alien to the New Testament... but evangelicals elevate it to the shibboleth of salvation!
