Preparing for the Feast of St. Margaret Mary

Tomorrow is the Feast of St. Margaret Mary. She really helped to spread devotion to the Sacred Heart and, as she was a Visitation nun, she was one of the first saints I learned about as a child. Here is something from the Catholic Encyclopedia so you will have an idea of both how she suffered and how careful the Church is in canonizing someone.

Margaret Mary was inspired by Christ to establish the Holy Hour and to pray lying prostrate with her face to the ground from eleven till midnight on the eve of the first Friday of each month, to share in the mortal sadness He endured when abandoned by His Apostles in His Agony, and to receive holy Communion on the first Friday of every month. In the first great revelation, He made known to her His ardent desire to be loved by men and His design of manifesting His Heart with all Its treasures of love and mercy, of sanctification and salvation. He appointed the Friday after the octave of the feast of Corpus Christi as the feast of the Sacred Heart; He called her "the Beloved Disciple of the Sacred Heart", and the heiress of all Its treasures. The love of the Sacred Heart was the fire which consumed her, and devotion to the Sacred Heart is the refrain of all her writings. In her last illness she refused all alleviation, repeating frequently: "What have I in heaven and what do I desire on earth, but Thee alone, O my God", and died pronouncing the Holy Name of Jesus.
The discussion of the mission and virtues of Margaret Mary continued for years. All her actions, her revelations, her spiritual maxims, her teachings regarding the devotion to the Sacred Heart, of which she was the chief exponent as well as the apostle, were subjected to the most severe and minute examination, and finally the Sacred Congregation of rites passed a favourable vote on the heroic virtues of this servant of God. In March, 1824, Leo XII pronounced her Venerable, and on 18 September, 1864, Pius IX declared her Blessed. When her tomb was canonically opened in July, 1830, two instantaneous cures took place. Her body rests under the altar in the chapel at Paray, and many striking favours have been obtained by pilgrims attracted thither from all parts of the world. Her feast is celebrated on 17 October. [Editor's Note: St. Margaret Mary was canonized by Benedict XV in 1920.]
