From a Christmas sermon by St John Chrysostom (349-407 AD):
“What shall I say! And how shall I describe this Birth to you? For this wonder fills me with astonishment. The Ancient of days has become an infant. God Who sits upon the sublime and heavenly Throne, now lies in a manger…
For this God assumed my body, that I may become capable of God’s Word; taking my flesh, God gives me his spirit; and so God bestowing and I receiving, God prepares for me the treasure of Life…I take my part, not plucking the harp nor with the music of the pipes nor holding a torch, but holding in my arms the cradle of Christ!
For this is all my hope! This is my life! This is my salvation! This is my pipe, my harp! And bearing it I come, and having from its power received the gift of speech, I too, with the angels and shepherds, sing:
Glory to God in the Highest! and on earth peace to all of good will!”
