J.M.J. Here is a marvelous quotation from Saint Louise de Marillac (1591-1660) that appeared in the March 17, 2015 e-mail newsletter of The Central Association of the Miraculous Medal.
As into a very precious vessel,
more and more graces
have been poured into Mary's soul,
and she has never failed to make
good use of them.
Therefore, with every good reason,
she should be honored by all creatures
and served in a particular way by Christians,
since she is the only pure creature
who has ever found favor in the eyes of God.
This makes her the astonishment of the heavenly court
and admiration of all humanity.
