Based on Jesus Through Medieval Eyes (the chapter on Christ as Word) and the O antiphons:
The Father's gathered syllables,
one long, unbroken Word
has lain these months invisible,
unspeaking and unheard.
E'er since the angel said it last,
the silent Word is cloaked
within the woman who said yes,
beneath her heart invoked.
To weave a word's embodiment—
eyes, hands, and lips and breath—
his mother is the sacred tent
of birth and life and death.
Unheard, yet he is not unknown;
unseen, yet still in mind,
a secret held by her alone
until the hours unwind.
Until he's born into the world,
no treatise but a child:
God's plan in him in her arms curled;
God's wisdom in her smile.
And how our silence aches to hear
his echoes in the dark,
for when he cries out, loud and clear,
the sky fills up with sparks.
