There has never been a civilization not based on a religion and ours is based on christianity. And each religion has a central mytho-poetic figure and ours is Jesus Christ.
It is possible, even likely, there was a real person, on whom the mytho-poetic Christ was based. However the mytho-poetic Christ is a world removed from the real or historical Jesus.
All those in love with Jesus are in love with the mytho-poetic Christ. And he is our mytho-poetic Christ.
