On Rev 11:19a:
We can understand by the temple
of God the blessed Mary; and by the ark of the Testament, Christ,
who took flesh from her. But the temple of God is not said to be opened because
the womb of the blessed Virgin Mary was opened in giving birth to the Lord, she
was a virgin before birth, a virgin in birth, a virgin after birth, but it is
said to be opened because through her our Lord Jesus Christ was made
visible to us. We can also understand by the temple the Old Testament, and by
the ark of the mysteries concerning Christ that are contained in the Old
Testament. For when Christ came in the flesh, the Old Testament was opened, and
the spiritual understanding that lay hidden in it was revealed to the faithful.
