Diarmaid McCulloch's BBC history of Chistianity offered a wonderfully simple metaphor for the enigma that Jesus is considered both human and divine. He took three glasses at his restaurant table: one of water, one of wine and one of olive oil. He poured the water into the wine and they mixed; the oil, though, floated on the water with a definite seperation. An early argument was whether the two natures were mixed or seperate. Reading the gospels, they seem very much mixed.
I wonder whether Philip Pullman has managed to seperate out from this mixture a sense of what the man Jesus might have been like? For Christians this is hugely important. It is after all the man whom we follow, his teaching which nourishes us and whose command we joyfully obey when we meet for bread and wine.
