Bishop Robinson says this about the Christmas story:

Suppose the whole notion of a God who visits the earth in the person of His Son is as mythical as the prince in the fairy story. Suppose there is no realm “out there” from which the man from heaven arrives. Suppose the Christmas myth (the invasion of this side by the other side), as opposed to the Christmas history (the birth of the man, Jesus of Nazareth), has to go. Are we prepared for that? Or are we to cling here to this last vestige of the mythological or metaphysical world view as the only garb in which to clothe the story with power to touch the imagination? Cannot perhaps the supernaturalist scheme survive at least as part of the “magic” of Christmas?
