This prayer is a favorite devotional of some of the priests at St. Benedict Abbey, Still River, MA.
It has become a favorite of mine, especially when I am praying for and about my children.
Remember, O most gracious Virgin Mary,
That never was it known, that anyone who fled to thy protection,
Implored thy help, or sought thy intercession, was left unaided.
Inspired with this confidence,
I fly unto thee, O Virgin of virgins, my Mother;
To thee do I come, before thee I stand, sinful and sorrowful.
O Mother of the Word Incarnate, despise not my petitions,
But in thy mercy hear and answer me. Amen.
The Memorare, from the Latin 'remember' which is the first word in the Latin translation, was traditionally thought to have been composed by the Cisterian St. Bernard of Clairvaux. It was popularized in the 15th century by a French priest, Claude Bernard (who some also attribute its origin). It emphasizes Mary's role as intercessor and her unbroken history of answering the prayer of those who call to her. - http://www.memorare.com/mary/marianprayershistory.html
