Tomorrow (June 8th) is the Feast of the Immaculate Heart of Mary.
While many are familiar with the Feast of the Sacred Heart of Jesus and the images associated with it, the Feast of the Immaculate Heart of Mary is lesser known. In 1638, St. John Eudes published his Devotion to the Most Pure Heart and Holy Name of Mary. St. John was a priest in France who spent his life preaching about the love of God and encouraging people to love Christ and Mary. The feast of the Immaculate Heart of Mary was first celebrated in 1648, however it didn’t gain a huge following until almost two centuries later.
In 1839, our Blessed Mother appeared to St. Catherine Laboure and gave her the image of the Miraculous Medal, which features the images of both the hearts of Jesus and Mary. At Fatima in 1917, Mary told Lucia that she was to remain on Earth to help promote devotion to her Immaculate Heart and the children saw in front of our Blessed Mother a heart surrounded by thorns.
In 1942 during the ravages of World War II, Pope Pius XII dedicated the world to the Immaculate Heart of Mary and set the feast for August 22nd. In 1969, Pope Paul VI moved the celebration of the Immaculate Heart of Mary to the day, Saturday, immediately after the Solemnity of the Sacred Heart of Jesus, and moved the feast of the Queenship of Mary from May 31st to August 22nd.
In 1984, Pope John Paul II renewed the consecration of the world to the Immaculate Heart of Mary. He repeated this in the year 2000, entrusting the world to Mary for the new millennium.
Therefore, it is not an end in itself, so the love of her heart is meant to be a model for the way we should love God. The fact that her heart is immaculate, that is sinless, means that she is the only fully human person who is able to really love God in the way that he should be loved.
Honoring Mary's Immaculate Heart is really just another way of honoring Mary as the person who was chosen to be the Mother of God, recognizing her extraordinary holiness and the immense love she bestowed on Jesus as his mother, the person who was called to share in and co-operate in his redemptive sufferings.
