The First Catholic Thanksgiving

America’s First Thanksgiving Was the Latin Mass
Before Plymouth’s turkey and town-hall prayer service, there was Our Lady’s altar in Spanish Florida

If you grew up in American schools, you were taught to imagine Thanksgiving as a kind of proto–Evangelical praise rally, held by brave Calvinists in funny hats who heroically escaped “Roman superstition,” planted an English Bible on the shore, and shared turkey with the locals out of pure, spontaneous gratitude.

The reality is delightfully inconvenient for that myth.

The first public act of thanksgiving on what would become American soil was not an extemporaneous Protestant prayer. It was a solemn Latin Mass on the feast of Our Lady’s Nativity, followed by a shared meal between Spanish Catholics and Native Americans, half a century before anyone at Plymouth had figured out how to grow corn.

In other words, the first Thanksgiving in America was Eucharist.

And it was in Latin.


Our Lady of the First Thanksgiving

On September 8, 1565, Pedro Menéndez de Avilés landed with about 800 settlers on the coast of what is now St. Augustine, Florida. Contemporary accounts and later work by historian Michael Gannon agree on the essential sequence: a cross was planted; Father Francisco López de Mendoza Grajales vested for Mass; the feast of the Nativity of the Blessed Virgin Mary was celebrated in thanksgiving for safe arrival; afterwards, the Spaniards and Timucua shared a meal.

Gannon famously called it “the first community act of religion and thanksgiving in the first permanent [European] settlement” in what became the United States.

So picture the scene.

A makeshift altar on the shore. A priest in Roman vestments. Menéndez and his soldiers kneeling in the sand. Latin prayers rising over the surf. Timucua onlookers watching as bread and wine are consecrated, the same Sacrifice that had sanctified Europe for a thousand years now offered in this new land. Only after the Holy Sacrifice do they sit down together to eat.

No sentimental “all faiths, no creed” ceremony. No civic pastor making up his own liturgy on the fly. Just the Roman rite, in Latin, on a Marian feast, with a communal meal attached.

That is the origin point the textbooks bury.

They prefer their alternative timeline, where American religious history begins when men who hated the Latin Mass finally manage to get far enough away from it.


Why the Myth Has to Start in Plymouth

If you admit that America’s first Thanksgiving was a Latin Mass offered by a Spanish priest under a banner of Our Lady, the whole story of “Protestant America” starts to wobble.

It is much cleaner to pretend that real history begins at Plymouth Rock in 1620. There the Pilgrims arrive, stage a drama of hardship and deliverance, and stage-manage a harvest feast that later gets repackaged as the founding liturgy of the American civil religion.

When Gannon went public with the St. Augustine claim, Plymouth reacted like someone had stolen their relic. New England officials held a special meeting; a Boston paper compared him to the “Grinch who stole Thanksgiving.”

Why such panic over a date?

Because the Plymouth story is not just about food and gratitude. It is a confessional myth. The Pilgrims are cast as pure Bible Christians, shaking off old-world corruption and superstition. To admit that the first formal American thanksgiving was Catholic is to admit that from the very beginning the faith of the Latin Mass had a prior claim on this soil.

Even more awkward: the Thanksgiving meal at Plymouth—assuming you accept the usual narrative—only happened because of a man who had been catechized and likely baptized by Catholic friars.


Squanto’s Franciscan Detour

The one indispensable human character in the Plymouth story is Tisquantum, better known as Squanto. Without him, the Pilgrims likely starve. He teaches them how to plant crops, where to fish, how to survive. He interprets between English Calvinists and Native tribes.

But Squanto does not drop from the sky as a neutral cultural mediator. Around 1614 he is captured by an Englishman, taken to Spain, and nearly sold into slavery. Franciscan friars intervene, secure his freedom, and instruct him in the Catholic faith; several accounts say he was baptized.

He spends time in Spain and England, works in shipyards, learns English, and eventually returns to his homeland shortly before the Pilgrims arrive. Only then does he become the bridge without which there is no “first Thanksgiving” in New England.

So even on the Protestant side of the myth, the crucial hinge is a man evangelized by Catholic religious, rescued from slavery by friars who believed in the dignity of a pagan soul enough to risk involvement and teach him the faith.

You do not need to canonize Squanto. You only need to notice the pattern. The standard civics-class narrative turns Thanksgiving into a story of white Calvinists and generic “Indians,” held together by the invisible hand of Providence and a vaguely deist God of the harvest.

But if you follow the actual historical threads, the story runs repeatedly through Catholic hands: friars in Spain, a baptized Patuxet, and—fifty years earlier—the altar on the shore of St. Augustine.

When Washington Went to High Mass on Thanksgiving

Fast forward three and a half centuries. You are in Washington, D.C., in the years before the First World War. Thanksgiving has become a civil holiday. The Protestant establishment likes it, because it smells like a church service minus dogma: prayers, hymns, God-talk, lots of flags, no papist complications.

Into this steps Msgr. William Russell at St. Patrick’s, just a few blocks from the White House. Beginning in 1909, he launches the annual Pan-American Thanksgiving Mass. Ambassadors and diplomats from Latin America attend, along with senior clergy. Presidents Taft and Wilson show up in person. Supreme Court justices and cabinet members are in the pews.

This is not a vague “interfaith” gathering with a color guard and a closing hymn. It is a solemn High Mass in the traditional Roman rite, offered for the nations of the Americas on Thanksgiving Day. Catholic bishops chant the Preface; incense rises; the Te Deum may be sung. Diplomats kneel when the bell rings at the elevation.

Russell and his allies are not trying to “Protestantize” Catholic worship for Thanksgiving. They are Catholicizing the holiday itself, insisting that the proper way for a nation to give thanks is at the altar.

Protestant commentators lose their minds. Catholic journals record indignation from those who see this as a stealth attempt to claim Thanksgiving for Rome, to present to foreign delegates the image of a United States that is not a Protestant nation at heart.

In other words, pre–Vatican II American Catholicism did not see Thanksgiving as a neutral civic exercise. When Catholics leaned into it, they did so by insisting that gratitude deserving the name must pass through the Sacrifice of the Mass.

And that Mass was in Latin.


How Pre-Conciliar Catholics Actually Kept the Day

In the parishes, thanksgiving was not a separate sacrament of vague national uplift. It was a votive Mass pro gratiarum actione, offered in the Roman Missal. Bishops like Camillus Maes of Covington explicitly ordered a High Mass of Thanksgiving on the civil holiday, with the traditional “Prayer for the Authorities” afterwards, uniting gratitude for temporal blessings with intercession for rulers.

By the mid-twentieth century, priests like Fr. Francis X. Weiser were folding Thanksgiving into a larger sacramental imagination. In his Handbook of Christian Feasts and Customs, Weiser treats Thanksgiving alongside liturgical feasts, explaining how Catholic families can keep the day in a genuinely Christian way: beginning with Mass; framing the meal with prayer; linking the harvest motif to older Catholic customs like Martinmas.

He even notes that Thanksgiving is the only non-Catholic feast he bothers to cover in detail, precisely because it can be baptized so naturally into the life of grace.

That was the pre-conciliar instinct: do not invent a parallel “spirituality of gratitude” alongside the sacraments. Bring the civic day under the wings of the altar. Let the Eucharist, the true “thanksgiving,” interpret the turkey and the pies, rather than letting the turkey reinterpret the Eucharist.

From Eucharistia to Generic Gratitude

Compare that to the post-conciliar landscape.

The American bishops’ recommended liturgical texts for Thanksgiving now tend to mimic the civic language around them. Homilies praise “our shared values” and “diverse faith traditions” and the “journey of a nation.” The Mass, often celebrated in the vernacular with ad-libbed prayers of the faithful, functions as one more “expression of gratitude” in a pluralist chorus, rather than the unique and objective act of thanksgiving that gives the holiday any supernatural meaning at all.

At the same time, Rome has been busily dismantling even the symbolic memory of Latin as the sacred tongue of Catholic worship. The very language in which America’s first Thanksgiving Mass was offered, and in which those Pan-American High Masses were sung, is treated as an optional lifestyle accessory, a private taste for nostalgic eccentrics.

This is not just a change in aesthetic.

Once you sever Thanksgiving from its sacramental root, you are left with a purely psychological virtue. Gratitude becomes a mood you can have with or without Christ, with or without the Church, with or without the Cross. The Eucharist becomes one “expression” among many, instead of the act from which all genuine thanksgiving takes its life.

And once you sever the Church from her own language, you make the historical continuity almost impossible to see. It becomes easy to forget that the first sustained Christian presence on this continent was not a circle of men inventing hymns in English, but a priest in chasuble, chanting the Canon in Latin over bread and wine on the Florida coast.


Remembering the Real Thanksgiving

If you are trying to live as a traditional Catholic in America, Thanksgiving will never be a pure feast. It sits uneasily at the intersection of Protestant mythology, civil religion, and genuine natural gratitude. It can be a strong temptation to either baptize the civic myth uncritically or reject the day entirely.

The older Catholic instinct offers a better path.

First, tell the truth about history. The real first Thanksgiving in what became the United States was a Latin Mass in honor of the Blessed Virgin Mary, followed by a shared meal between Spanish Catholics and Native Americans at St. Augustine in 1565.

Second, remember that even the Plymouth story, to the extent it has any depth, stands on Catholic shoulders: on Franciscan friars who rescued a kidnapped Patuxet and taught him the faith, and on the baptized man who then became the human bridge without which the Pilgrims’ feast never happens.

Third, return the holiday to the altar. Let the Mass of Thanksgiving—ideally the traditional Roman Mass, in the language in which America first heard the Canon—be the center of the day. See the family table as an echo of the altar, not the other way around.

One of the cruelest tricks of the post-conciliar era has been to persuade Catholics that Latin is a museum piece and that our own story begins in 1965. Thanksgiving, of all days, exposes how false that is.

Long before English Protestants staged their founding meal, long before presidents issued proclamations, long before saccharine interfaith prayer services, a priest in Spanish Florida lifted the Host above a sandy shore and gave thanks in the only way that ultimately matters.

America’s first Thanksgiving was the Latin Mass.

Everything else is an afterward.
