Dr Russell Norman--Member of Parliament, Co-leader of the Greens, and an atheist--does a masterful job of articulating both the theology and implications of the incarnation in the first seven to eight minutes of his speech to Parliament. It's well worth a look, though it takes maybe 30 seconds to load.
Proud to be a Kiwi, though why this guy isn't a Christian in light of what he says is almost as much of a mystery as the incarnation.
