Who do you say that I am?

 

Readings: Isaiah 22:19–23; Romans 11:33–36; Matthew 16:13–20

I will never forget my first trip to Rome, the Eternal City.

It was only a few weeks after my ordination. I traveled with a priest brother who had been ordained alongside me, both of us still marveling that God had entrusted something so enormous to men so young. Rome overwhelmed us at every turn—the sights, the sounds, the sheer weight of two thousand years pressing in from every stone. But nothing prepared me for the moment I first stepped through the doors of St. Peter’s Basilica.

Breathtaking would be an understatement.

I remember tilting my head back and looking up into that immense dome—the same dome you can see rising above the rooftops from nearly anywhere in the city, the dome that seems to gather all of Rome underneath it. And running around the base of that dome, in letters taller than a man, is an inscription in Latin. I stood there, a brand-new priest, and read it slowly, syllable by syllable, and felt something settle into my bones that has never left me:

Tu es Petrus, et super hanc petram aedificabo Ecclesiam meam... et tibi dabo claves regni caelorum.

You are Peter, and upon this rock I will build my Church... and I will give you the keys of the kingdom of heaven.

To be Catholic is to believe in that reality. Not as a slogan carved in gold letters for tourists to photograph, but as a living fact: the Church was founded on the rock of Peter’s faith, and that foundation still holds, twenty centuries later, with a basilica the size of a small city standing on top of it.

Today’s Gospel takes us back to the moment before the dome, before the mosaics, before any of it—to a dusty crossroads in Caesarea Philippi, where Jesus turns to his closest friends and asks the question that every generation of believers must eventually answer for itself: Who do people say that the Son of Man is?

The disciples offer him the safe answers, the answers that keep Jesus comfortably inside categories everyone already understands. Some say John the Baptist. Others, Elijah. Still others, Jeremiah or one of the prophets. All flattering. All respectful. All beside the point.

Then Jesus makes it personal. But who do you say that I am?

This is, at the heart of it, the question upon which our entire faith turns. Not what the polls say. Not what the commentators say. Not what is fashionable to say. Who do you say that I am.

And it is Peter—Simon, the fisherman, a man with calloused hands and no formal education, a man who would go on to deny Christ three times before the rooster crowed—who answers. Theologians have spent two thousand years unpacking the depths of what he said, reaching for philosophical categories, for the language of nature and person and hypostatic union, trying to do justice to the mystery. And they are right to keep trying; the mystery is inexhaustible. But Peter himself did none of that. Peter did not consult a manual. He simply said what had been given to him to say:

You are the Christ, the Son of the living God.

That confession, friends, that is the heart and center of the Christian faith. Everything else—every doctrine, every sacrament, every line of the Creed we will profess again in a few minutes—is an unfolding of what is already contained in those eleven words spoken by an unlettered fisherman on a dusty road.

And notice what Jesus does with that confession. He does not simply say, “Correct.” He builds on it. Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my heavenly Father. And then the promise that would one day be carved into the dome of a basilica: You are Peter, and upon this rock I will build my Church, and the gates of the netherworld shall not prevail against it.

You will be ever secure in my everlasting love. Nothing—not persecution, not scandal, not schism, not the failures of her own sons and daughters, not even the gates of hell itself—will ever finally destroy the community and the body that is the Church. That is not a claim about our worthiness. God knows we have never earned it. It is a claim about God’s fidelity. The Church stands not because we have built her well, but because Christ has promised to hold her.

And here is where our second reading meets our Gospel, though at first glance they might seem to be speaking of entirely different things. Paul, reflecting on the mystery of God’s plan for Israel and for all the nations, breaks into that magnificent doxology: Oh, the depth of the riches and wisdom and knowledge of God! How inscrutable are his judgments and how unsearchable his ways! Paul is contemplating something vast—the reconciliation of all things, Jew and Gentile alike, in a mercy wide enough to hold everyone.

That, I think, is the same mercy Peter stumbled into on the road to Caesarea Philippi. Peter did not earn his confession through study. It was given to him. And the Church that Christ built on Peter’s faith is not a fortress for the deserving; she is the vessel of a reconciliation that will, in the end, embrace far more than any of us dare to imagine—a love that will have no end, riches and wisdom rooted in the very knowledge of God, offered not because we have solved the mystery of who Christ is, but because, like Peter, we have simply been given the grace to say so.

I still think of that dome sometimes. Of a young priest, weeks into his ministry, craning his neck to read a promise in Latin letters taller than himself. I did not understand then everything that promise would ask of me, or everything it would carry me through in the years since. I am not sure any of us ever fully understand it. But I have come to trust it the way Peter must have trusted the words that came out of his own mouth before he even had time to reason his way to them.

Who do you say that I am?

May we answer, today and every day, as Peter did—not with the polish of theologians, but with the plain confidence of a man who has simply been shown the truth, and knows better than to complicate it: You are the Christ, the Son of the living God.
