O splendid jewel

The Catholic Church celebrates the Immaculate Conception of Mary today.

O splendid jewel, serenely infused with the Sun!
The Sun is in you as a fount
from the heart of the Father;
It is his sole Word, by whom he created the world,
The primary matter, which Eve threw into disorder.
He formed the Word in you as a human being,
And therefore you are the jewel that shines most brightly,
Through whom the Word breathed out
the whole of virtues
As once from primary matter he made all creatures.

--Hildegard of Bingen – Twelfth century
