Alliance of the Hearts of Jesus and Mary

[2] After Pope John Paul II remarked on "the admirable alliance of the Hearts of Jesus and Mary" in 1985, several symposia were held on the concept.

However, other Mariologists dismissed the entire concept of the Two Hearts as mere 'devotionalism', having no real value for scientific Marian theology because of its association with private revelation.

[4] The devotion was practiced by Bernard of Clairvaux, Hermann Joseph von Steinfeld, Lutgardis, the Franciscans, Dominicans, and Carthusians.

The feast of the Sacred Heart was first celebrated, with episcopal approval, through the influence of John Eudes on 31 August 1670 at the major seminary of Rennes.

[9] Eudes was partly influenced by the writings of Francis de Sales on the perfections of the Heart of Mary as the model of love for God.

By the beginning of the 19th century the devotion to the Immaculate Heart was sufficiently widespread in Europe for Pope Pius VII to allow a feast to honor it in 1805.

Since the 17th century, the devotions to the Hearts of Jesus and Mary, individually and jointly, have been promoted and encouraged by a number of saints and the blessed.

[19] In the 1956 encyclical Haurietis aquas, Pope Pius XII stated, "In order that favors in great abundance may flow on all Christians, nay, on the whole human race, from the devotion to the most Sacred Heart of Jesus, let the faithful see to it that to this devotion the Immaculate Heart of the Mother of God is closely joined.

[1] In the 1979 encyclical Redemptor hominis (item 22), Pope John Paul II said,We can say that the mystery of the Redemption took shape beneath the heart of the Virgin of Nazareth when she pronounced her "fiat".

The view of the sacraments as gifts to the church positions the Hearts as the primary channel of Christ's boundless love and Mary's endless compassion.

[31] On Christmas Eve in 1800, amid the French Revolution, knowing they could face the guillotine for their actions, Peter Coudrin and Henriette Aymer de Chevalerie established the Congregation of the Sacred Hearts of Jesus and Mary with a mission to spread the message of God's love manifested through the Hearts of Jesus and Mary and through the adoration of the Blessed Sacrament.
