The Most Revolutionary Document in History

So said Tolstoi, of this text:

My soul doth magnify the Lord, and my spirit hath rejoiced in God my Saviour. For he hath regarded the low estate of his handmaiden: for, behold, from henceforth all generations shall call me blessed. For he that is mighty hath done to me great things; and holy is his name. And his mercy is on them that fear him from generation to generation.

He hath shewed strength with his arm; he hath scattered the proud in the imagination of their hearts. He hath put down the mighty from their seats, and exalted them of low degree. He hath filled the hungry with good things; and the rich he hath sent empty away.

--from the first chapter of Luke, in the King James version

Now if Mary could see that the birth of Jesus means that the powerful are dethroned, and the rich dismissed, then what prevents the followers of Jesus, who sit in seats of power and privilege, from seeing it?

What was that about a War on Christmas?
