O tu illustrata

Here’s a Marian antiphon by Saint Hildegard of Bingen, video link below:

O tu illustrata
de divina claritate,
clara Virgo Maria,
Verbo Dei
infusa,
unde venter tuus floruit
de introitu
Spiritus Dei,
qui in te
sufflavit
et in te exsuxit
quod Eva abstulit
in abscisione puritatis,
per contractam
contagionem de
suggestione diaboli.Tu mirabiliter abscondisti in te
inmaculatam carnem
per divinam racionem,
cum Filius Dei
in ventre tuo floruit,
sancta divinitate
eum educente
contra carnis iura
que construxit Eva,
integritati copulatum
in divinis visceribus.
Illumined by
God’s clearest brightness,
O Virgin Mary bright,
with the Word of God
infused,
your womb then flourished at
the entrance of
God’s Spirit—
within you
he breathed,
within drew out
the loss of Eve,
a purity cut off and silenced
by that disease
contracted at
the Devil’s sly persuasion.You wondrously held hid within yourself
a flesh kept undefiled
according to God’s Reason—
for when the Son of God
within your womb was blossomed,
divinity most holy
brought him forth
to abrogate the laws of flesh
establishéd by Eve,
for he was joined to whole integrity
in flesh and womb divine.
