Hornebo1For TODAY the Maker of
the world was born of a Virgin’s womb, and He, who made all natures,
became Son of her, whom He created!

TODAY the Word of GOD appeared
clothed in flesh, and That which had never been visible to human
eyes began to be tangible to our hands as well!

TODAY the shepherds
learnt from angels’ voices that the Saviour was born in the
substance of our flesh and soul!

And TODAY the form of the Gospel
message was pre-arranged by the leaders of the LORD’S flocks, so
that we too may say with the army of the heavenly host: "GLORY IN THE HIGHEST TO GOD, AND ON EARTH PEACE TO MEN OF GOOD WILL!"

From the Sermon on the Feast of the Nativity (VI) by St. (Pope) Leo the Great.  I’ve added  most of the capitals and the exclamation marks to capture the joy of Christmas Day.
