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. He who sits upon the sublime and heavenly throne now lies in a manger. And he who cannot be touched, who is without complexity, incorporeal, now lies subject to human hands. He who has broken the bonds of sinners is now bound by an infant’s bands. But he has decreed that ignominy shall become honor, infamy be clothed with glory, and abject humiliation the measure of his goodness. For this he assumed my body, that I may become capable of his word; taking my flesh, he gives me his spirit; and so he bestowing, and I receiving, he prepares for me the treasure of life. He takes my flesh to sanctify me; he gives me his Spirit, that he may save me.
Truly wondrous is the whole chronicle of the nativity. For this day the ancient slavery is ended, the devil confounded, the demons take to flight, the power of death is broken. For this day paradise is unlocked, the curse is taken away, sin is removed, error driven out, truth has been brought back, the speech of kindliness diffused and spread on every side – a heavenly way of life has been implanted on the earth, angels communicate with men without fear, and we now hold speech with angels.
–St. John Chrysostom
