The Sacred Heart of Jesus

The Catholic claim

The Sacred Heart devotion honors the love of Jesus Christ symbolized by his human heart—pierced for our salvation and still the living fountain of mercy for the Church.

Biblical evidence

From Christ's pierced side flow blood and water. Jesus is gentle and lowly of heart. The New Covenant is written on hearts; Christian devotion contemplates the Redeemer who loved his own to the end.

• John 19:34

  “However one of the soldiers pierced his side with a spear, and immediately blood and water came out.”

• Matthew 11:29

  “Take my yoke upon you, and learn from me, for I am gentle and lowly in heart; and you will find rest for your souls.”

• John 13:1

  “Now before the feast of the Passover, Jesus, knowing that his time had come that he would depart from this world to the Father,”

• Luke 12:49

  “I came to throw fire on the earth. I wish it were already kindled.”

• Ephesians 3:17-19

  “that Christ may dwell in your hearts through faith; to the end that you, being rooted and grounded in love,”

Tradition and magisterium

Popes have strongly recommended Sacred Heart devotion (e.g., Leo XIII, Pius XII). The Catechism roots it in the mystery of the Incarnate Word's love.

Private revelations (such as to St. Margaret Mary) may encourage devotion but do not add public revelation. The heart of the devotion is dogmatic: God really became man and loves with a human heart.

History and development

Medieval devotion to Christ's wounds matured into Sacred Heart piety in the modern era. The Church approved the feast and practices while warning against superstition.

• Ignatius of Antioch

  Letter to the Romans 7:3 · A.D. 110

  “I have no taste for corruptible food nor for the pleasures of this life. I desire the bread of God, which is the flesh of Jesus Christ, who was of the seed of David; and for drink I desire his blood, which is love incorruptible”

• Justin Martyr

  First Apology 66 · A.D. 151

  “We call this food Eucharist, and no one else is permitted to partake of it, except one who believes our teaching to be true and who has been washed in the washing which is for the remission of sins and for regeneration [i.e., has received baptism] and is thereby living as Christ enjoined. For not as common bread nor common drink do we receive these; but since Jesus Christ our Savior was made incarnate by the word of God and had both flesh and blood for our salvation, so too, as we have been taught, the food which has been made into the Eucharist by the Eucharistic prayer set down by him, and by the change of which our blood and flesh is nurtured, is both the flesh and the blood of that incarnated Jesus”

• Irenaeus

  Against Heresies 4:17:5 · A.D. 189

  “He took from among creation that which is bread, and gave thanks, saying, ‘This is my body.’ The cup likewise, which is from among the creation to which we belong, he confessed to be his blood. He taught the new sacrifice of the new covenant, of which Malachi, one of the twelve [minor] prophets, had signified beforehand: ‘You do not do my will, says the Lord Almighty, and I will not accept a sacrifice at your hands. For from the rising of the sun to its setting my name is glorified among the Gentiles, and in every place incense is offered to my name, and a pure sacrifice; for great is my name among the Gentiles, says the Lord Almighty’ [Mal. 1:10–11]. By these words he makes it plain that the former people will cease to make offerings to God; but that in every place sacrifice will be offered to him, and indeed, a pure one, for his name is glorified among the Gentiles”

• Clement of Alexandria

  The Instructor of Children 1:6:43:3 · A.D. 191

  “’Eat my flesh,’ [Jesus] says, ‘and drink my blood.’ The Lord supplies us with these intimate nutrients, he delivers over his flesh and pours out his blood, and nothing is lacking for the growth of his children”

• Tertullian

  The Resurrection of the Dead 8 · A.D. 210

  “[T]here is not a soul that can at all procure salvation, except it believe whilst it is in the flesh, so true is it that the flesh is the very condition on which salvation hinges. And since the soul is, in consequence of its salvation, chosen to the service of God, it is the flesh which actually renders it capable of such service. The flesh, indeed, is washed [in baptism], in order that the soul may be cleansed . . . the flesh is shadowed with the imposition of hands [in confirmation], that the soul also may be illuminated by the Spirit; the flesh feeds [in the Eucharist] on the body and blood of Christ, that the soul likewise may be filled with God”
