The one person, Jesus Christ, both true God and true man, stooped into our littleness to draw us up to the greatness of life eternal, which is not this life infinitely extended but is the very life of God. From the beginning and through the millennia, human beings looked upward in search of the divine. Mary looked downward, at the baby in her arms. She looked into the very face of God. Finitum capax infiniti, the finite is capable of the infinite. This is the central wonder, the inexhaustible mystery, of Christmas.
-- Richard John Neuhaus
Which is a quite good echo of Chestertonian paradox, I'd say:
A mass of legend and literature, which increases and will never end has repeated and rung the changes on that single paradox; that the hands that had made the sun and stars were too small to reach the huge heads of the cattle. Upon this paradox, we might almost say upon this jest, all the literature of our faith is founded.
-- G. K. Chesterton, The Everlasting Man, 1926
Hope you're having a jolly one. More later, if I can shake free.
