It is in the old Christmas carols, hymns, and traditions—those which date from the Middle Ages—that we find not only what makes Christmas poetic and soothing and stately, but first and foremost what makes Christmas exciting. The exciting quality of Christmas rests on an ancient and admitted paradox. It rests upon the paradox that the power and center of the whole universe may be found in some seemingly small matter, that the stars in their courses may move like a moving wheel around the neglected outhouse of an inn.G. K. Chesterton
