"The incomparable thing, what the whole world cannot grasp, much less describe, is that from Mary's flesh and blood he takes his human nature. Then he lets himself be carried in her arms, nourished by the milk of the Virgin; then she is a mother and a virgin. And she shall tower over all holy women, so that the angels are amazed."
-Martin Luther. He also wrote his doctoral dissertation on the Blessed Virgin Mary.
(by the way, Luther, I'm still waiting for my hood!)
