The Holy Father's homily at Midnight Mass at St. Peter's. READ IT!
In some way, mankind is awaiting God, waiting for him to draw near. But when the moment comes, there is no room for him. Man is so preoccupied with himself, he has such urgent need of all the space and all the time for his own things, that nothing remains for others - for his neighbour, for the poor, for God. And the richer men become, the more they fill up all the space by themselves. And the less room there is for others.[snip]
Anselm of Canterbury, in an almost prophetic way, once described a vision of what we witness today in a polluted world whose future is at risk: "Everything was as if dead, and had lost its dignity, having been made for the service of those who praise God. The elements of the world were oppressed, they had lost their splendour because of the abuse of those who enslaved them for their idols, for whom they had not been created" (PL 158, 955f.). Thus, according to Gregory's vision, the stable in the Christmas message represents the ill-treated world. What Christ rebuilds is no ordinary palace. He came to restore beauty and dignity to creation, to the universe: this is what began at Christmas and makes the angels rejoice. The Earth is restored to good order by virtue of the fact that it is opened up to God, it obtains its true light anew, and in the harmony between human will and divine will, in the unification of height and depth, it regains its beauty and dignity. Thus Christmas is a feast of restored creation.
