What is Faith?

Faith is not a lukewarm feeling that washes over us on sunny mornings, nor a mathematical certainty that neatly solves the equation of the universe. Faith is, above all, an act of surrender: the soul’s resounding “yes,” knowing itself wounded and finite, hurling itself toward the One who calls it. It is Mary’s fiat, Abraham’s “Here I am,” the desperate father’s cry: “Lord, I believe; help my unbelief” as he begged for his demon-tormented son.

In the midst of the metastases gnawing at my brain, of lesions that grow even as the drugs struggle to contain them, faith is not the absence of fear. It is the decision to keep walking though the fog is thick and the ground trembles beneath our feet.

How much of this is rational decision and how much pure divine Grace? The question is not idle; it strikes at the very nerve of the Christian paradox. On one hand, faith is reasonable. It is not blind. The great Doctors—Thomas Aquinas, Augustine, Newman—remind us that reason can reach the threshold: it can demonstrate the existence of a First Mover, the internal coherence of Revelation, the reasonable historicity of the Resurrection. Reason clears the ground, prunes the absurd objections of crude materialism, and points out that the universe itself shouts order and purpose. It is fides quaerens intellectum: faith seeking understanding, yet never born from understanding alone.

And yet, no one ever comes to believe by syllogisms alone. At the depths there is a leap, a gift. Grace. That light which cannot be manufactured, that impulse no muscular effort of the soul can conquer. Saint Paul says it with raw bluntness: “No one can say ‘Jesus is Lord’ except by the Holy Spirit.” Grace breaks in, touches, invites. Sometimes with an almost imperceptible gentleness; other times like a blow—being thrown from the horse, struck by illness, loss, the dark night of the soul.

In my own case, I will welcome Grace even when she arrives dressed in scans, oncological reports, pain, and uncertainty. She does not annul reason; she perfects it. Reason carries the torch as far as it can; Grace kindles it when the wax runs out.

How do they combine? In a tense and fruitful dance. Reason prepares the house; Grace enters and dwells in it. The will decides to open the door, even while trembling. Here enters Freddy Mercury’s “the show must go on,” or the laughter of Garrick I have written about before: to act as if we possessed the faith that sometimes deserts us.

Is this mere theater? Pride disguised as piety? In part, yes. Pride always lurks—the stubborn refusal to yield, the dread of appearing as a man who has collapsed. But something deeper is at work, something the saints and the Desert Fathers knew well.

Planting the flag, “putting on the show,” is an act of anticipated obedience. It is telling the rebellious soul: “Even if I feel nothing right now, even if prayer is arid and the heavens seem like bronze, I will kneel. I will pray the Rosary. I will keep the schedule. I will write even when the words weigh like lead.” It is not pretending to have perfect faith; it is exercising the imperfect faith we already possess. Like the terrified soldier who obeys the order to advance because the flag has already been planted on the hill.

Pride may provide the first push, but Grace purifies it. What begins as stubbornness becomes fidelity. What is born of obstinate will slowly opens itself to the will of God.

They say that at the Battle of Rocroi, on May 19, 1643, during the Thirty Years’ War, the young Duke of Enghien—later the Great Condé—at barely twenty-one years old, faced the legendary Spanish tercios under Francisco de Melo. The battle raged in the Ardennes, near the frontier fortress. The tercios, undefeated in open field for more than a century, formed the impenetrable center of the Spanish infantry. The day hung in the balance: the French left wing had been shattered, the artillery was threatened, and the thrust of the veteran Spaniards seemed poised to tilt the scales toward imperial victory.

In that moment of apparent defeat, Condé, in a stroke of desperate genius, hurled his commander’s baton behind the enemy lines and rallied his men: they would have to go and retrieve it. That audacious act—risking the very symbol of authority in hostile territory—set the French troops ablaze. They seized the offensive with renewed fury, enveloped the tercios, isolated the Spanish elite, and won a decisive victory that marked the end of the tercios’ military supremacy in Europe. Condé had staked everything on a symbolic gesture, trusting that this bold act would change the course of events. And it did.

So it is with planting the flag in the spiritual life. It is not denying the gravity of the moment—the advancing lesions, the failing strength, the whispering doubts—but throwing the baton of our poor will beyond fear, beyond what reason alone deems possible, and hurling ourselves forward to retrieve it. The tercios of our unbelief may seem invincible; yet a gesture of faith, even if born partly from stubborn pride or the simple refusal to surrender, opens the breach through which Grace bursts in with power.

I think of the martyrs. Many did not die in mystical ecstasy. They died afraid, doubting, with their stomachs in knots. But they had planted the flag earlier: in the dark days, in the vigils, in the small and seemingly absurd decisions. “Though He slay me, yet will I trust in Him,” says Job. This is not euphoria; it is holy stubbornness. It is “the show must go on” elevated to the supernatural order.

In this my battle against a melanoma that will not yield, against new lesions appearing while others shrink, against the anemia that steals my strength, faith is not a feeling that always sustains me. Sometimes it is an almost military act of will: I rise, I pray, I write, I love my own, I keep working, I keep dreaming of walking my daughter down the aisle. I act as if faith were unbreakable. And in that acting, Grace finds the cracks through which to enter. The initial pride—“I will not surrender, because I refuse”—is gradually filed down, slowly transformed into abandonment. Fiat voluntas tua.

Faith, then, is not the possession of a permanent luminous certainty. It is an alliance: reason that points out the path, will that plants the flag though the wind howls—or hurls the baton beyond the tercios of doubt—and Grace that, in its hour, transforms the rag of a flag into a living standard. “The show must go on” is not hypocrisy when done before God and for God. It is the humility of one who knows his faith is small as a mustard seed, yet still sows it and waters it with tears and sweat.

Because in the end, it is not about feeling faith. It is about being faithful. And fidelity, very often, begins with the stubborn gesture of one who, though his heart is cold, plants the flag—or hurls the baton—and keeps marching. The God who is Good takes care of the rest. He always does. My reason tells me so, and I hope that soon Grace will make me feel it as well.
