September 15
Our Lady of Sorrows is invoked as patron of the suffering. The Memorial of Our Lady of Sorrows, kept the day after the Exaltation of the Holy Cross, contemplates the Mother of God in her share of the Passion of her Son. The feast originates in the medieval devotion to the Compassio Mariae and was approved for the Servite Order, founded in 1233 in Florence, in 1668.
