Luther and Lewis

Behold, how He combined the two. He raises up seed for Abraham, the Natural son of one of his daughters, a pure virgin, Mary, through the Holy Spirit and without her knowing a man. Here there was no natural conception with its curse, nor could it touch this seed; and yet it is the natural seed of Abraham, as truly as any of the other children of Abraham. This is the blessed Seed of Abraham, in whom all the world is set free from its curse.—Martin Luther, Magnificat AE 21:353

It looks, in fact, very much as if both parties had in mind some kind of Law or Rule of fair play or decent behavior or morality or whatever you like to call it, about which they really agreed. And they have. If they had not, they might, of course, fight like animals, but they could not quarrel in the human sense of the world. Quarelling means trying to show that the other man is in the wrong.—C. S. Lewis, Business of Heaven, p. 247.
