One from Joseph Ratzinger, as he was then (1959):
It is the birthday of the undefeated Light, the winter solstice of world history, which gives us the certainty amid the rise and decline of this story that here, too, the light will not die, but has already achieved the final victory.
Christmas drives out of us the second, greater fear that physics cannot dispel. This is the fear of humanity and before man himself. It is a divine certainty that the light has already conquered in the hidden depths of history, and that all the great progress of evil in the world in the end can do nothing more about it. The winter solstice of history has irrevocably taken place in the birth of the Child from Bethlehem.
And one from National Review's Kevin Williamson, a somewhat grim one:
Man is meat. About that there is no question. The question is whether he is to be only that. We Christians should not be too otherworldly, because the facts as we understand them are bloody before they are glorious and glorious only because they are bloody. The truth of the Incarnation — God as meat — is not that the facts and events and suffering of this world do not matter in light of the glorious kingdom to come but that they do matter. Meat matters. Blood, too. Metaphor won’t do. The Incarnation is our only link to that other kingdom.
