From the Holy Father's homily for Midnight Mass:
It starts with a situation not unlike our own: everyone is bustling about, getting ready for an important event, the great census, which called for much preparation. In that sense, the atmosphere was very much like our modern celebration of Christmas. Yet the Gospel has little to do with that worldly scenario; it quickly shifts our gaze to something else, which it considers more important. It is a small and apparently insignificant detail that it nonetheless mentions three times, always in relation to the central figures in the narrative. First, Mary places Jesus “in a manger” (Lk 2:7); then the angels tell the shepherds about “a child wrapped in swaddling clothes and lying in a manger” (v. 12); and finally, the shepherds, who find “the child lying in the manger” (v. 16). In order to rediscover the meaning of Christmas, we need to look to the manger. Yet why is the manger so important? Because it is the sign, and not by chance, of Christ’s coming into this world. It is how he announces his coming. It is the way God is born in history, so that history itself can be reborn. What then does the manger tell us?...
