There is, after all, something revolutionary in Christianity — a tendency to upend, reverse, and radically transform. In Mary’s magnificat, the song of praise, she offers at her meeting with her cousin Elizabeth, she proclaims, “My soul magnifies the Lord, and my spirit rejoices in God my Savior, for he has looked with favor on the lowliness of his servant . . . He has brought down the powerful from their thrones, and lifted up the lowly; he has filled the hungry with good things, and sent the rich away empty.” This list of upsets issues from the mouth of a peasant girl who has been promoted to an almost unimaginable status. That the radical reversals of Christmas are enumerated to us by a young woman of no particular social standing is itself an incredible bit of turnabout.

The revolutionary character of Christianity is usually washed out and mostly confined to specific political moments when it’s useful to refer to it. But this selectivity, too, should be upended. Christianity is at all times concerned with the poorest, the most vulnerable, the most oppressed; it is permanently interested in reversing this order, in aiming at and accomplishing the unexpected.
