Mary, Mother of Jesus (St. Edith Stein)

Mary stands at the crucial point of human history
and especially at the crucial point
of the history of woman;
in her, motherhood was transfigured
and physical maternity surmounted.

 --St. Edith Stein 

The oldest known hymn dedicated to Mary was found on a papyrus dating back to 250 AD and was clearly already being used in liturgies of the time.

We fly to thy patronage, O Holy Mother of God
Despise not our petitions in times of necessity,
But deliver us always from all dangers,
glorious and blessed virgin.

--Gregorian Chant,
Sub Tuum Praesidium

Today is the Solemnity of Mary, Mother of God.

Mary, Mother of Jesus, please be a mother to me now! 
(St. Mother Teresa of Kolkata)
