As we ponder the true story of God coming to earth as a man, yet retaining His deity, I thought it was fitting to post the following excerpts of C. S. Lewis's thoughts on the matter.
"Now as myth transcends thought, Incarnation transcends myth. The heart of Christianity is a myth which is also a fact. The old myth of the Dying God, without ceasing to be myth comes down from the heaven of legend and imagination to the earth of history. It happens—at a particular date, in a particular place, followed by definable historical consequences.
We pass from a Balder or an Osiris, dying nobody knows when or where, to a historical Person crucified (it is all in order) under Pontius Pilate. By becoming fact it does not cease to be myth: that is the miracle."
~ C. S. Lewis, Myth Became Fact
In a 1931 letter to his friend Arthur Greeves, Lewis hints at the message of the essay referenced above...
"Now what [Hugo] Dyson and Tolkien showed me was this: that if I met the idea of sacrifice in a Pagan story I didn’t mind it at all: again, that if I met the idea of a god sacrificing himself to himself . . . I liked it very much and was mysteriously moved by it: again, that the idea of the dying and reviving god (Balder, Adonis, Bacchus) similarly moved me provided I met it anywhere except in the Gospels.
The reason was that in Pagan stories I was prepared to feel the myth as profound and suggestive of meanings beyond my grasp even tho’ I could not say in cold prose “what it meant.” Now the story of Christ is simply a true myth: a myth working on us in the same way as the others, but with this tremendous difference that it really happened: and one must be content to accept it in the same way, remembering that it is God’s myth where the others are men’s myths: i.e. the Pagan stories are God expressing Himself through the minds of poets, using such images as He found there, while Christianity is God expressing Himself through what we call “real things.”
Therefore it is true, not in the sense of being a “description” of God (that no finite mind could take in) but in the sense of being the way in which God chooses to (or can) appear to our faculties. The “doctrines” we get out of the true myth are of courseless true: they are translations into our concepts and ideas of that which God has already expressed in a language more adequate, namely the actual incarnation, crucifixion, and resurrection."
There is so much that I want to say about story, myth particularly, both showing truth and being true... But I would rather let Lewis's words soak into your mind and heart.
