Marian Prayer of St. Gregory the Great, Pope

Mary, you are the vessel
and tabernacle containing all Mysteries.
You know what the Patriarchs did not know;
you experienced what was not revealed to the Angels;
you heard what the Prophets did not hear.
In short, everything that was hidden
from preceding generations
was made known to you;
even more,
most of these wonders depended on you.
