The Bread of Life is Not Optional

At every Mass, the Church sets before us the bread of life. On the feast of Corpus Christi, she does so with special boldness. This Corpus Christi homily asks a blunt question: is the Eucharist a pleasant extra for believers, or is it the very source of eternal life? As we will see, the answer runs through Scripture, through a medieval crisis of faith, and through the heart of Christ himself.

Old Testament Types Point Forward to Christ

Scripture scholars read the Bible through several lenses. One of the most important, especially when we compare the Old Testament with the New, is what they call typology. Because the New Testament fulfills the Old, the two are joined by deep connections, and scholars call these connections types.

Consider a few examples. Adam, the first man, is a type of Jesus, the new Adam (Cf. Rom 5:14; 1 Cor 15:45.) Eve, in turn, is a type of Mary, the new woman. The Ark of the Covenant is also a type: it foreshadows Mary, who carried in her womb the new law and the new promise.

We heard another type in the hymn we just sang: Isaac. You remember the story. God asked Abraham to sacrifice his only son, and Abraham was about to obey when an angel stopped him (cf. Gn 22). Isaac, therefore, is a type of Jesus, the Son who was sacrificed that we might have life.

Notice one pattern, however. The new symbols of the New Testament always surpass the old ones with greater glory. So Jesus Christ surpasses Adam. Mary surpasses both Eve and the Ark of the Covenant, with greater power and fullness, fulfilling all the prophets and the law.

Manna in the Desert: “What Is This?”

But then we come to today’s story: the manna. The word manna comes from a phrase that literally means “what is this?” (In Hebrew, man hu; cf. Ex 16:15.) So picture the Jewish people wandering in the desert. They feel hunger, and they begin to question God.

Then one morning a man wakes up, sees something on the ground, and asks, “What’s this?” He tastes it, finds it satisfying, and offers some to his neighbor. “Here, have some.” “What’s this?” “I don’t know, but eat it.” After a few days the phrase catches on. “Here, have some what’sthis” becomes “Here, have some manna.” Eventually they realize the truth: it is bread from heaven, God himself feeding his people (cf. Ex 16).

Now ask yourself a harder question. How could anyone surpass bread given directly by God? Could anything outdo bread sent down from heaven?

Jesus Says He Is the Bread of Life and Means It

We hear the Lord’s own answer today: “I am the bread that came down from heaven” (Jn 6:41; cf. Jn 6:51). This bread is no longer an object through which the Father feeds his people. This bread is a Person, which is exactly why our faith rests on Someone and not on mere ideas.

The Lord presents this teaching with striking urgency, because for a Christian the Eucharist is not a nice luxury. You might assume you can believe in Jesus while staying neutral about the Eucharist. Yet listen to his words: “Unless you eat my flesh and drink my blood,” you cannot receive the life he offers (cf. Jn 6:53). In other words, you are simply not capacitated for immortality without it.

This teaching sits so close to the Lord’s heart that he returned to it at the very end. On the night before he died, he took bread and said, “Take this and eat; this is my body” (Mt 26:26). Then he offered the cup, his life-blood poured out to give us new life (cf. Mt 26:27-28). This bread of angels strengthens you. Therefore the Church rightly calls it the bread of immortality that gives eternal life.

A Medieval Crisis: When the World Called Matter Evil

To feel the weight of this teaching, travel back to the 13th century. The Holy Roman Empire faced attacks on many fronts. From the east, the Mongols had devastated one Christian kingdom after another, the defense of the Holy Land was crumbling, and tension ran high between the empire and the Church.

Yet one internal threat proved even more corrosive than these external ones. A heresy had taken root for more than a hundred years. We call it the Cathar, or Albigensian, heresy, and it struck at a specific nerve in Catholic doctrine.

This heresy taught that all matter is evil. The body is evil, it claimed, along with all its desires. Food, drink, and everything material is evil, while only the spiritual is good.

Why the Incarnation and the Sacraments Were at Stake

The Church saw exactly where this logic led. If matter is evil, then God would never have taken up matter – he would never have become incarnate to save us. So the Incarnation never happened, and if the Incarnation never happened.

That conclusion would gut the core of our faith. It would also empty the sacraments, because the sacraments are material realities that carry spiritual grace: bread, wine, water, oil. Therefore, to deny any goodness in matter is to deny essential doctrines of the faith.

This is also why the Eucharist still answers every age that despises the body. Many people today repeat a softer version of the same error, treating the spiritual as “real” and the physical as disposable. Pope Urban IV recognized the danger and weighed his options.

Pope Urban IV, a Persistent Nun, and a Bleeding Host

Should the pope raise an army to defend the Holy Land? Could he issue documents teaching the truth? Or might he open relations with the Mongols? He weighed each path as the crisis deepened.

Years earlier, a humble nun had urged him to exalt the body of Christ, the very matter in which God took flesh. At first he hesitated, unsure whether one nun’s pious wish belonged on the calendar of the universal Church.

Then he heard a remarkable story from a nearby town, Orvieto. The crisis of doubt had seeped even into the hearts of believers and priests. Where was God in all these wars, deaths, and divisions?

The Miracle of Bolsena and the First Feast of Corpus Christi

As one priest celebrated Mass, he too wrestled with doubt. Could God really take material form in our flesh? Was this truly the body and blood of Jesus? While he harbored these doubts, the host began to drip real blood onto the corporal.

The corporal is the cloth that protects the altar and catches any crumbs that fall. Its very name comes from corpus, the Latin word for body. To the priest’s amazement, the bleeding host stained that cloth and became an object of devotion.

When Pope Urban IV heard the news, he said, “I want to see that.” God has often revealed his mysteries through Eucharistic miracles. Even today, such miracles puzzle scientists who study their tissue and pigmentation, and they still witness to the union of matter and spirit.

Aquinas, the Procession, and Grace Through Matter

For Urban, the bloodstained cloth confirmed what the nun had begged him to do years before. So he made his decision: the Church would carry the visible, adorable body of Christ out into the streets. We would dare to proclaim that the Father sent his Son, that the Son took flesh and died for us, and that he meant every word when he said, “This is my body.”

He established a new feast, the feast of the Body and Blood of Christ, which we celebrate today as Corpus Christi. He also commissioned St. Thomas Aquinas to compose its hymns, including the very sequence we sang, the Lauda Sion. Thus the body and blood of Christ remain at the center of the Church’s worship.

How true it is, brothers and sisters, that grace works through material realities, not in spite of them. Through the sacraments, God conveys saving grace. That, surely, explains the urgency in the heart of our Lord: take and eat, because you cannot have life otherwise.

Tolkien on the One Great Thing to Love on Earth

J.R.R. Tolkien, the author of The Lord of the Rings, had a deep devotion to the Eucharist. In his day, fathers often wrote letters to their children at important moments. So in 1941 Tolkien wrote to his son Michael about love, women, and the trials of a faithful marriage.

Tolkien knew that life holds real darkness and that marriage demands perseverance. So he offered his son a few enduring lines:

“Out of the darkness of my life, so much frustrated, I put before you the one great thing to love on earth: the Blessed Sacrament. There you will find romance, glory, honour, fidelity, and the true way of all your loves on earth.”

Notice the heart of his counsel. If you want to stay faithful to any earthly love, then keep first in your heart the greater love by which you have been loved. There, in the Blessed Sacrament, you find all romance, all glory, and all fidelity in the One who stayed faithful to the point of death.

Communion Means Common Union

The mystery of the Incarnation is also the mystery of transubstantiation, and we can grasp it only through the lens of love. At its center stands the holy desire of Jesus to be one with you.

That desire is exactly what the word communion means: common union. So in those precious seconds after Communion, when you return to your pew and enter your inner room, you are one with the One who is Love. Take that to heart.

I invite you, therefore, to cultivate a Eucharistic devotion. Come to the Lord a few minutes before Mass and gather your heart in peace. Or stay a few minutes afterward with the One with whom you remain in communion, the God who keeps seeking us even in our darkest hours.

He Sees You: An Invitation to the Bread of Life

Let me speak personally. In high school, in college, and through my professional life, I often found consolation in the Blessed Sacrament. In moments of discouragement, after a breakup, amid struggles at work or at home, I would go to my church in Guadalajara and simply spend an hour in silence.

I did not go to ask the Lord to fix everything. Rather, I went to know that he is with me, that he truly sees me. Is that not what he promised? “Behold, I am with you always, until the end of the age” (Mt 28:20).

So what is there to fear when the saving grace of the Lord rests with you and within you? This is the heart of the bread of life: not a doctrine to admire from a distance, but a Person who feeds you. Let us pray, then, for the humility to be amazed by this love, and for the courage to love him back in the sacrament that holds all romance, all glory, and all fidelity, the new manna by which you and I are fed.
