"My heart and my flesh have rejoiced in the living God." (Psalm 83:4)
Devotion to the Immaculate Heart of Mary has grown along side of the devotion to the Sacred Heart, for the heart of the Mother can never be separated from that of her Son. According to the visionary St. Bridget of Sweden (14th century), Our Lady said: "As Adam and Eve sold the world for one apple, so my son and I redeemed the world, as it were, with one Heart." (Sign of Her Heart by John Haffert)
St. John Eudes, who in the 17th century promoted devotion to the Two Hearts, reported to have heard Our Lord saying: "I have given you this admirable heart of My dearest Mother which is but one with Mine, to be truly your heart also, in order that the children may have but one heart with their Mother...." (Ibid.)
The Belgian mystic Berthe Petit (1870-1943) experienced several revelations concerning the "Sorrowful and Immaculate Heart of Mary." She recorded Jesus as saying:
This devotion to the Sorrowful and Immaculate Heart of My Mother will restore faith and hope to broken hearts and to ruined families...it will sweeten sorrow. It will be a new strength for My Church, bringing souls not only to confidence in My Heart, but also to abandonment to the Sorrowful Heart of my Mother. (Prayers and Heavenly Promises by Joan Carroll Cruz)The 1917 apparitions of Our Lady in Fatima, Portugal led to Pope Pius XII instituting the feast of the Immaculate Heart of Mary. Originally kept on August 22, the memorial of the Immaculate Heart is presently kept on the day after the Solemnity of the Sacred Heart.
The mystery of the Immaculate Heart is the mystery of the Mercy of God; the mercy He showed to Mary by preserving her from all stain of original sin; the mercy He bestows on us through the prayers of the Mother of Mercy, the Mediatrix of all Graces, on our behalf. It is a mystery of compassion, for Mary's heart was pierced with sorrow at the foot of the cross. The brown scapular of Carmel is a sign of one's personal consecration to Our Lady, as well as of the compassionate intercession we hope to receive from her at the hour of death.
Sr. Lucy of Fatima said: "Our Lady wants all to wear the scapular." (Haffert) The scapular is an exterior sign of interior abandonment to the Heart of Mary. The Carmelite Venerable Michael of St. Augustine wrote:
We can live in Mary if we strive, in all our deeds and omissions, in our penances and trials and afflictions, to preserve and promote within ourselves a filial, tender inclination of soul towards Mary....Our love will then flow, as it were, from God to Mary and from Mary back to God. (Life with Mary by Ven. Michael of St. Augustine)
