A Feast Placed the Day After the Cross on Purpose

Our Lady of Sorrows falls on the fifteenth of September, the date this rule records, deliberately positioned the day immediately after the Exaltation of the Holy Cross on the fourteenth, joining Mary's grief to the cross itself in the calendar's own structure rather than leaving the connection to be inferred. The devotion behind the feast, meditation on seven traditional sorrows in Mary's life culminating in Christ's death, developed within the Servite Order, the Servants of Mary, founded in the thirteenth century, whose members promoted devotion to Mary's suffering as a central part of their own spirituality from the order's earliest period.

The feast's path onto the universal Catholic calendar was gradual, kept locally and by the Servite order themselves for centuries before its wider adoption, and its establishment for the whole Church is associated with Pope Pius the Seventh in eighteen fourteen, a pope who had personally experienced years of imprisonment and exile under Napoleon and who is traditionally connected to promoting devotions tied to suffering and endurance following his own return to Rome. As with most of the Marian feasts clustered on this part of the calendar, the observance is specifically Catholic in its formal liturgical form, resting on a devotional tradition with no equivalent formal date in Orthodox or Protestant calendars, even where both traditions share a broader devotion to Mary's grief expressed in other ways.
