The Feast of the sacred of Jesus is celebrated on June 12 every year. The popes of the 20th century praised devotion to the Sacred Heart, calling it “necessary” and “the sum of all religion.”
Mother Teresa explained how she has been devoted to the Sacred Heart since her childhood, and, citing the Gospel, she said “You have to learn from the Sacred Heart of Jesus. That is why Jesus said: ‘Learn of me’ — not from books.’” That sold me. The Catholic faith is set up such that St. Thomas Aquinas can write theological masterworks about it—and illiterate people can have just a similar deep experience of the faith as him.
Think about how the Church inspires us without using words: In baptism, water washes our head, and our soul; and I can’t imagine a better way for Christ to say, “I want to be united completely with you, and I want you to take me out of the Church and into the streets,” than through his real presence in communion. It’s so simple, a child can comprehend it. The Sacred Heart is that way.
Firstly, the sacred heart of Jesus is a heart—not a brain devotion. There is no formal devotion to the Sacred Brain of Jesus that I know of. There is, moreover, a devotion to the Soviet Brain of Lenin. Vladimir Lenin’s brain was taken from his corpse at his death and studied by scientists ready to find a key therein to the brilliance of the mastermind of the Soviet revolution.
The two devotions—ours to the heart, theirs to the brain—are telling. Lenin started the vast system of Soviet communism; his legacy was its rules, its ideology, and its hierarchy, and his brain was the thing that devised it. Jesus Christ also began a system—the Church—with rules, teachings, and hierarchy. But that’s not what is basically relevant to him: The fact of the incarnation is. We honor Jesus’ heart, not his brain. For us, his legacy is his very life—the very fact of his existence, as God and man, living among us.
Secondly, it is also not an aura. We live in a world where people believe that being “spiritual” and being “religious” are two different things. The Sacred Heart reminds us that “spirit” does not exist in some ethereal magical alternate plane of reality.
Our spirits and our bodies are one.
The Sacred Heart is a countersign to “spiritual but not religious. Any child who looks on it sees very clearly that in it God is telling us that his incarnation was real—that he was truly human and truly divine—and that our holiness is not a halo outside us, but a reality in the very depths of us.
Thirdly, it shows us what involvement in the life of the Trinity means. A priest once described how his vocation began when he stared at his family’s picture of the Sacred Heart as a child.
I saw him giving me his heart,” he said. “So I asked him to take mine. He had purified himself to the Sacred Heart before he understood what that could possibly mean. The sacrament of baptism is supposed to make us “a participant in the divine life of the Trinity.” One thing that means is this: The persons of the Trinity exist in a continual mutual self-gift, one to the other. The Father gives all to the Son; the Son returns all to the Father and the Holy Spirit proceeds from that love, giving all back.
Then we offer ourselves to God in the sacraments and enter into the lesser consecrations that mirror and support the sacraments—consecration to the Sacred Heart or to the Blessed Mother—we enter into the Trinity’s self-giving. Pope John Paul II describes what this looks like Through the union of the Heart of Jesus to the Person of the Word of God we can say: in Jesus, God loves humanly, suffers humanly, rejoices humanly. And vice versa: in Jesus, human love, human suffering, human glory obtain divine intensity and power.”
