Sept. 15 - Our Lady of Sorrows

From here: This feast dates back to the 12th century. It was especially promoted by the Cistercians and the Servites, so much so that in the 14th and 15th centuries it was widely celebrated throughout the Catholic Church. In 1482 the feast was added to the Missal under the title of "Our Lady of Compassion." Pope Benedict XIII added it to the Roman Calendar in 1727 on the Friday before Palm Sunday. In 1913, Pope Pius X fixed the date on September 15. The title "Our Lady of Sorrows" focuses on Mary's intense suffering during the passion and death of Christ. Elsewhere: It was installed in the liturgical calendar by the local [Cologne, Germany] bishops as an expiatory act, to make reparation to God and to Our Lady for the heresy of iconoclasts who adhered to the errors of Jan Hus.

"In the West, the second feast, which arose as a particular feast of the Servites, was extended, slightly less than a century after Benedict’s decree, to the whole of the Western Church by Pius VII. The Holy Father was likely motivated by temporal events of the time, wishing to honor Our Lady in gratitude for the preservation of the Church and the papacy from the yoke of Napoleon and the “enlightened” revolutionaries."

From a St. Bernard sermon:

Perhaps someone will say: “Had she not known before that he would not die?” Undoubtedly. “Did she not expect him to rise again at once?” Surely. “And still she grieved over her crucified Son?” Intensely. Who are you and what is the source of your wisdom that you are more surprised at the compassion of Mary than at the passion of Mary’s Son? For if he could die in body, could she not die with him in spirit? He died in body through a love greater than anyone had known. She died in spirit through a love unlike any other since his.
