Early Christianity and Greek culture collide: metaphor vs metamorphosis

Greek culture and philosophy did not understand metaphors, but it did understand metamorphosis. In their mythology gods changed often into other persons or beings. Metaphors were quite alien to them though. When early Christianity, based in its Hebraic mythology of metaphors, met the Greek culture, Christianity's metaphors were changed to Greek metamorphic concepts. Example: the last supper, instead of the bread and wine being symbols or metaphors, they were "metamorphed" (transubstantiated) into the actual blood and body of Christ. And since only a god could do something like this, Jesus was deified, that is, became a God, and his message, instead of one about social justice and change, changed to one about life after death and individual redemption.
