It was at the Last Supper that John, the disciple “whom Jesus loved,” reclined on the Sacred Heart of Jesus. (Jn. 13:23) Just hours later, at the foot of the Cross, it was John again who witnessed Jesus’ Sacred Heart being pierced by a lance. He noted that “one of the soldiers pierced His side with a spear, and at once there came out blood and water.” (Jn. 19:34) The early Church Fathers interpret the blood and water sacramentally, as symbols of the blood of the Eucharist and the waters of Baptism.
The sacraments and the Church sprung from the wound of Christ’s Heart. St. Augustine makes the connection that just as Eve was drawn from the side of Adam during his “deep sleep” (Gen. 2:21), so too, was the Church, the bride of Christ, drawn from the side of Jesus in His death. It is in the waters of Baptism and the blood of the Eucharist that the Church is born and sustained. The Church appropriately venerates the Sacred Heart of Jesus, which “He allowed to be pierced by our sins,” as the definitive symbol of divine love towards humanity. (CCC 2669)
The 1956 encyclical Haurietis Aquas, on the Devotion to the Sacred Heart, opens by quoting the prophet Isaiah, who writes about the life-giving waters of the suffering Messiah. Isaiah declares, “You shall draw waters with joy out of the savior’s fountains,” (Is. 12:3) and “every one who thirsts, come to the waters.” (Is. 55:1) The other prophets too, Joel, Ezekiel, and Zechariah, speak of these life-giving waters of the Savior. Jesus Himself quotes the prophets saying that whoever believes in Him “rivers of living water will flow from within him.” (Jn. 7:38) What is this life-giving water? The early Church Fathers recognized the water that flowed from His Sacred Heart as the grace from the sacraments. It is a symbol of the outpouring of the Holy Spirit. The living water is the sacramental water of Baptism, in which the Holy Spirit cleanses us of sin and comes to dwell within us. Jesus tells Nicodemus we must be born again of “water and spirit,” just as He tells the Samaritan woman at the well, “the water that I shall give him will become in him a spring of water welling up to eternal life.” (Jn. 4:14)
It is not a coincidence that the feast day of the Sacred Heart of Jesus comes in the liturgical calendar just after Pentecost, commemorating the gift of the Holy Spirit. The Holy Spirit proceeds from the depths of Jesus’ Heart. The feast of the Sacred Heart is also the first Friday within the Octave of Corpus Christi, celebrating the real presence of Jesus’ body and blood in the Eucharist. This is fitting, as the Sacred Heart of Jesus is part of His physical body. In that sense, when we receive the Eucharist, we are receiving the Sacred Heart of Jesus. (H.A. 122) The blood that pours forth from His pierced heart at Calvary symbolizes the “blood of the new covenant” that Jesus offers up at the Last Supper, in which we partake at every Mass.
By the 17th century, the Faith was in tumult, particularly in France, dealing exteriorly with the Protestant Revolution and interiorly with the Jansenist heresy. Jansenism denied the free will of man, advocating that only those predestined by God would receive sanctifying grace. These teachers purported a moral rigorism, resulting in many people being denied Holy Communion due to their faults and sins. It was against the backdrop of this narrow worldview, constricting the sacraments of grace to only a few, that Jesus appeared to St. Margaret Mary Alacoque and said, “Behold this Heart, which has loved men so much, that It has spared nothing, even to exhausting and consuming Itself, in order to testify to them Its love.” Jesus shows that He offers Himself up, not for a few, but for the love of all people, and desires them to receive Holy Communion frequently. He requested that a feast day be established in honor of His Sacred Heart, and that people should go to Holy Communion on the first Friday of every month, as well as regularly keeping Holy Hour adoration. Jesus did, in fact, renew the life of the Church, enlivening the hearts of believers, with this devotion to His Sacred Heart.
Jesus also made a number of famous promises (more than the generally assumed twelve promises) to St. Margaret Mary regarding those who would have a devotion to His Sacred Heart. These included, among others, bringing peace to their families, consoling them in their troubles, granting them all the necessary graces in their lives, helping them become more fervent and perfect in their faith, and inscribing their names on His Heart forever. In a letter from May 1688, St. Margaret Mary wrote about “the Great Promise” that Jesus told to her. He said, “I promise you that My all powerful love will grant to all those who will receive Communion on the First Fridays, for nine consecutive months, the grace of final repentance.” As wonderful as this promise is, we should remember this is not an automatic guarantee to heaven. We should discern away any superstition involved with this. As Fr. James Kubicki, S.J., the National Director of the Apostleship of Prayer, writes this is “not magic but the natural consequence of a life lived in union with the Heart of Jesus.” We are not called to superstition, but to devotion.
Our devotion to the Sacred Heart is most fully expressed in our devotion to the Church. The blood and water of the Eucharist and Baptism make us anew. His Spirit dwells within us giving us eternal life. This is the fulfillment of the great prophecy of Ezekiel. The scripture says, “And I will give them a new heart, and put a new spirit within them; I will take the stony heart out of their flesh and give them a heart of flesh.” (Ez. 11:19-20) And so it is with us. Our hearts are conformed, and remade, in the sacraments to the Sacred Heart of Jesus.
As Jesus hung on the Cross, He cried out “I thirst.” In the lens of Christianity, Jesus’ thirst is to save souls. We can in a very real way console the Sacred Heart of Jesus and His thirst to save souls, through our reparation and devotion to His Sacred Heart. (Miserentissimus Redemptor, 13) Properly understood, Baptism and Eucharist transform us, who partake in them, into the Body of Christ. Through the life-giving waters of Jesus we are made clean, and through His body and blood we are transformed. In this, the beloved disciple, St. John, is our example; resting our heads on the breast of Jesus, listening closely to the sublime beats of His Heart, He makes us new creations.
