Alliance of the Hearts of Jesus and Mary

The Alliance of the Hearts of Jesus and Mary is a concept in Catholic theology that refers to the spiritual association between the Sacred Heart of Jesus and the Immaculate Heart of Mary. This idea was notably referenced by Pope John Paul II during his Angelus Address on 15 September 1985, where he described the two hearts as being "interrelated by reason of the enduring relation of love that exists between the Son and his Mother"

Following the address, several symposia were convened to examine the theological and devotional significance of the concept. While the devotion to the Sacred Heart of Jesus has a long-established theological background, these conferences primarily focused on the Immaculate Heart of Mary—exploring its scriptural basis and role within Catholic tradition.
