“For from the rising of the sun even to the going down, My name is great among the Gentiles, and in every place there is sacrifice, and there is offered to My name a clean oblation.” (Mal. 1:11)
This article continues and expands the meditation begun in my previous post, The Mass as God’s Wonderful Promise and Gift. There, I focused on the Mass as a hidden treasure and the Eucharist as the greatest Gift God could give—God Himself. Here, I turn to a closely related theme: the Real Presence as a doctrine that demands living faith, visible reverence, and (at times) extraordinary signs by which our Lord has strengthened His Church when belief was attacked or mocked.
These reflections are drawn from and inspired by the nineteenth-century Redemptorist priest Father Michael Mueller (1825–1899), whose devotional and doctrinal works aimed to press Catholic truths into the imagination and conscience until a man is forced to ask: Do I actually believe what I say I believe? Mueller’s book on the Mass—first published in 1874 and recently re-typeset and edited—was warmly commended in its own day and deserves renewed attention in ours.
In adapting these meditations for publication here, I will rely far less on extended quotations and more on explanation and application. Still, Mueller’s voice will appear at key moments. I will format any direct quotation as a block quote so it can be footnoted easily.
I. Real Presence: The Doctrine That Reorders Everything
It is one thing to confess with the lips that Our Lord is present in the Blessed Sacrament. It is another to live as though it were true.
Catholics often speak—rightly—of the Mass as the unbloody renewal of Calvary. We know (at least in theory) that the Sacrifice of the Cross is made present sacramentally; that the Mass is true worship, true oblation, true sacrifice; and that the Eucharist is not merely a symbol or representation, but Jesus Christ Himself—Body, Blood, Soul, and Divinity—under the sacramental veils.
And yet the modern world grows louder, more frantic, and more distracted by the day. Even for practicing Catholics, it becomes easy to treat the Mass as one more event on a weekly schedule: attended, fulfilled, and quickly forgotten. That shift does not happen all at once. It begins quietly: a loss of awe, a habit of distraction, a reduced sense of sin, and a practical assumption that the Eucharist is “holy,” yes—but not the kind of holiness that demands trembling reverence.
But if the Real Presence is true, then everything changes. The tabernacle is not a decorative box. It is not an ornament for the sanctuary. It is a throne. It is Bethlehem and Calvary and the Upper Room gathered into one hidden location where the God-Man truly dwells. If Christ is there, then a church is not merely a room for religious gathering; it is a sacred place because the King is present. And if the King is present, then every Catholic is bound not merely to “believe,” but to adore.
It is precisely because this doctrine reorders everything that the devil hates it and the world resists it. The Real Presence is not merely a comforting devotion; it is a declaration of divine authority. It says: God is here. God speaks. God reigns. God judges. God sanctifies. God demands worship. And for fallen man, that is intolerable unless he repents.
II. Christ Permits Evil to Draw From It a Greater Good
If the Eucharist is the heart of the Church, we might ask why God has permitted it to be attacked, denied, mocked, profaned, or treated casually—even among those who claim the name of Christian. Why allow heresy at all? Why allow irreverence to spread?
The Catholic answer is not that God wills evil. He does not. But He permits evil—and He permits it in such a way that, without compromising His holiness, He draws from it a greater good: the strengthening of the faithful, the purification of devotion, the exposure of error, the humiliation of pride, and the more brilliant vindication of truth.
This is the logic of the Cross. Our Lord allowed Judas to betray Him and Peter to fall. He allowed Himself to be scourged, mocked, and crucified. The malice was real; the injustice was real; yet the providence of God was greater still. From the darkest hour, God drew the world’s redemption.
So too in Eucharistic history: when belief grew cold, when heresy grew bold, and when the sacred mysteries were assaulted, God permitted trials. And at times of His choosing, He answered those trials with confirmations—sometimes quiet and interior, sometimes public and extraordinary—so that the faithful might be strengthened, the wavering corrected, and the proud rebuked.
This must be said clearly: miracles do not replace doctrine, and signs do not create faith. The Church’s authority is sufficient. Still, it has pleased God at certain times to grant remarkable confirmations—not because the Church needs spectacle, but because man’s heart is slow, forgetful, and often stubborn.
III. Corpus Christi and the Mercy of Public Adoration
One of the clearest examples of God drawing a greater good from an age of danger is the Feast of Corpus Christi. The feast is not a medieval embellishment. It is a providential response to the needs of the Church—especially when Eucharistic faith was challenged and devotion threatened.
The heart of Corpus Christi is remarkably simple: the Church publicly does what she always does interiorly—she confesses what she believes. The Eucharistic procession is a sermon preached without words: Christ is here. The same Lord Who once walked the roads of Judea now passes through our streets, not because He needs honor, but because we need to honor Him. Public worship becomes a form of reparation and a remedy for a forgetful world.
Mueller points to the purpose of Corpus Christi with characteristic directness:
“This means was the institution of the Feast of Corpus Christi.”
And he emphasizes why it mattered at the time it arose:
“It was instituted by divine inspiration in order that the Catholic doctrine might be strengthened by the institution of this festival, at a time when the faith of the world was growing cold and heresies were rife.”
Whether we consider the historical development of the feast or its enduring spiritual fruit, the lesson is the same: when faith is threatened, the Church does not retreat into ambiguity. She proclaims Christ more openly. The Host is lifted up not as a symbol, but as the living Lord. And the faithful are invited to order their interior life according to what the Church dares to confess in public: that Jesus Christ is truly present.
In our own day, Corpus Christi remains an essential anchor for authentic Eucharistic renewal. It teaches Catholics to worship outwardly what they claim to believe inwardly. It teaches that reverence is not optional; it is the natural language of faith.
IV. The Evils of Protestantism and the Assault on the Eucharist
To understand why the Church has clung so tightly to Eucharistic devotion—and why she has insisted upon clarity—we must speak honestly about what happens when the Real Presence is denied.
The Protestant revolt was not merely a dispute about external ceremonies or church governance. At its heart was a revolt against the sacrificial priesthood and the Eucharistic mystery. Once the Mass is denied as a true sacrifice, and once transubstantiation is rejected, the Eucharist is reduced—first to a symbol, then to an occasional memorial, and eventually to a matter of subjective meaning rather than objective reality.
And historically, the denial did not remain theoretical. Where the Eucharist was rejected, the fruits often followed: contempt for Catholic worship, ransacking of churches, ridicule of altars, destruction of sacred vessels, mockery of adoration, and the stripping away of the very instincts of reverence. When a culture abandons the truth that God is truly present among us—hidden under the sacramental veil—reverence collapses. And when reverence collapses, blasphemy and cruelty are never far behind.
This is why the Church has always treated Eucharistic doctrine as a matter of life and death, not as an item for polite ecumenical vagueness. If Christ is not truly present, then Catholic worship is superstition. But if Christ is truly present, then Protestantism is not merely “a different emphasis.” It is a denial of the Lord’s own words: “This is My Body.”
And because God is merciful even to the weak and wavering, He has sometimes granted extraordinary signs precisely in such ages—so that the faithful might be strengthened and the arrogant humbled.
V. Nicola Aubry and the Terrifying Clarity of Spiritual Warfare
Among the most arresting narratives Mueller presents is that of Nicola Aubry. Modern sensibilities do not like such stories. Yet the case teaches an unforgettable lesson: the devil knows the truth about the Eucharist even when heretics deny it; and Christ, in His sovereignty, can force even His enemies to confess what unbelief refuses to adore.
What is especially striking about this episode is that it is not presented as mere curiosity. It is doctrinal and moral. It reveals the hatred hell bears toward the Eucharist, and it highlights the authority Christ has placed in His Church.
Mueller frames the matter with a question that cuts to the heart of providence:
“Why this struggle between Our Lord and satan, since our divine Savior is his Lord and Master?”
His answer, in substance, is that God permitted the trial in order to sanctify, to instruct, to confirm Catholic doctrine, and to draw a greater good from what the devil intended for ruin. In this case, our Lord’s victory becomes a kind of living catechism: it teaches that Christ is present, that the Eucharist has power, and that even infernal hatred must yield before the King Who hides Himself under humble appearances.
One cannot read such accounts and still pretend that the Eucharist is a harmless symbol. The devil does not rage against symbols. He rages against reality. He rages against Christ’s sacramental Presence because the Eucharist is Christ’s nearness to man—Christ’s condescension, Christ’s mercy, Christ’s kingship, Christ’s claim upon souls.
This is why the Church has always insisted that reception of Holy Communion must be worthy: free from mortal sin, approached with reverence, prepared by repentance. The Eucharist is not a common thing. It is the Holy of Holies.
VI. The Power of Our Lord’s Body
Mueller repeatedly returns to a central point: the Host appears small, silent, unimpressive—but omnipotence is hidden there. The God-Man is not divided. Wherever He is present, His power and majesty are present, even if veiled.
He expresses the paradox plainly:
“So, when we look upon the Sacred Host it is true, we see there no mark of His Majesty… Yet, for all that, Jesus does not lack the power and means to manifest Himself in the Sacred Host as the Lord of Heaven and earth…”
This is precisely why Eucharistic devotion tests the sincerity of faith. God hides Himself so that man will be humbled, so that the soul will learn to prefer divine testimony over sensory evidence, and so that love may become pure—seeking God for God’s sake, not merely for the thrill of visible marvels.
Yet in mercy, God has at times allowed that veil to be partially lifted. Not because the ordinary Eucharist is “less real,” but because man’s heart is often forgetful. And when God grants such signs, they function like the miracles of Christ in the Gospel: they confirm doctrine, strengthen the faithful, and rebuke unbelief.
VII. The Miracle of Augsburg and Three Extraordinary Favors
Among the most sobering accounts is the miracle associated with Augsburg. While the details are striking, the spiritual meaning is even more striking: irreverence toward the Eucharist is never a small sin; and when Christ permits extraordinary confirmation, it is both mercy and warning.
The narrative involves sacrilege—a soul receiving Holy Communion and then committing a grave profanation by keeping the Host. Such a sin does not bring freedom; it brings misery. In the story, conscience becomes a torment until repentance returns. That alone is an important lesson: one cannot “possess” Christ as a talisman. The Eucharist is not a charm, and it does not tolerate being treated as an object.
When the Host is finally returned and the priest examines what had been hidden, the account describes a visible change—one meant to confirm, terrify, and instruct:
“On taking the two pieces of wax apart, he beheld, instead of the species of bread, human flesh, and even the muscular fibers.”
And again, the narrative emphasizes a further manifestation:
“the Sacred Host split at once in two… united by muscular fibers.”
Mueller presents this episode not as spectacle but as instruction. Such a miracle becomes, in effect, a catechism written in flesh rather than ink. It forces the question: if Christ’s Body is truly present, how dare we approach without reverence? How dare we receive in mortal sin? How dare we treat the altar casually? How dare we reduce the Eucharist to a symbol?
When Mueller speaks of “extraordinary favors” associated with such miracles, the point is not that we should chase marvels. The point is that God sometimes grants concrete confirmations to restore fear of God, to awaken repentance, and to strengthen faith where it has grown weak.
VIII. Eucharistic Miracles Still Today
There is a temptation to assume that Eucharistic miracles belong only to distant centuries. But the Church’s history repeatedly shows that God has sometimes granted such confirmations even in relatively recent times. The point is not to build a spirituality that depends on marvels; the point is to recognize that God is not absent from our age, even when unbelief is loud.
When such miracles occur, they function like the miracles of Christ in the Gospel: they confirm doctrine, strengthen the faithful, and expose the poverty of skepticism. They are signs of mercy—given not because the Church lacks evidence, but because hearts lack attention.
But perhaps the greatest “miracle” needed today is not that accidents visibly change, but that Catholics would recover Catholic instincts: silence, recollection, confession, reparation, and adoration. The Real Presence demands a real response. It calls us not merely to “attend Mass,” but to worship God with our whole heart, to repent of sin, and to receive Holy Communion worthily.
IX. Practical Application: What Eucharistic Faith Requires
If we want Eucharistic renewal in a serious sense, it will not be achieved merely by banners, slogans, or programs. It requires the restoration of Catholic life at its roots:
- Frequent confession, because the Eucharist is not a right but a Gift, and because mortal sin and Holy Communion cannot coexist.
- Reverent liturgy, because what we do at the altar teaches what we believe.
- Eucharistic adoration, because worship trains the soul to receive rightly and strengthens faith more than argument alone.
- Reparation, because the Eucharist has been denied, mocked, and abused, and love demands that we make amends.
- Doctrinal clarity, because confusion is not charity, and ambiguity does not save souls.
Corpus Christi teaches that public confession of faith matters. The history of Protestant denial teaches that the Eucharist is always contested. Nicola Aubry teaches that hell itself testifies to the Eucharist’s power. Augsburg teaches that irreverence wounds the soul and that Christ’s Body is truly present. And the broader witness of
