The Mother of God--the treasure house and mistress of God's riches

Just as it was only through [the Theotokos] that the Son came to us, was seen on earth and lived among men --- after previously being invisible to all, so from now on, for endless eternity: all progress towards the manifestation of divine light; every revelation of divine mysteries; and all forms of spiritual gifts are beyond everyone's grasp without her.  She was the first to receive the all-pervading fullness of Him, Who fills all things; and she brought Him within reach of all - distributing to each as he is able to receive, in proportion to the measure of his purity - such that she is both the treasure-house and the mistress of God's riches.
