First Mass

There's a version of American Catholic history most of us absorbed without ever being taught it directly. It goes something like this: Catholics show up in the story as immigrants, Irish, Italian, Polish, crowding into eastern cities in the 1800s, building parishes next to tenements, being discriminated against by Protestant communities, and eventually electing a president in 1960 who had to promise the country he wouldn't take orders from Rome. It's a real story, but it's not the full story.

The other half, the older half, starts in places that don't get main billing in our history curriculums: a beach at Point Loma, a mission compound outside Zuni pueblo territory, in sunny Santa Fe, or a garrison chapel on a Caribbean bluff, or a French Jesuit outpost along the Great Lakes, much of this decades before the storied Pilgrims set foot on Plymouth Rock. Catholics were in America early. Mass was being said, in Latin, under Spanish and French sovereignty, in what is now the United States, while England was still deciding whether Jamestown was going to survive its first winter. This is not fringe history, it's already acknowledged, it's just not as widely known, and it's not incorporated into American history.

That's the gap I built First Mass to close.

Why I'm doing this

I've spent the last couple years, mostly on this Substack and over on @_CatholicWest, digging into the Spanish and Mexican-era roots of Catholicism in the American West: Garcés blazing a path through Arizona & California, Kino riding circles around the Pimería Alta, the Kumeyaay Revolt, the California missions, and so much more. The more of that ground I covered, the more obvious a structural problem became. There was no single place to just see our roots. No map, no table, no "here is another place where the American Catholic story actually started, in this county, with this priest, and here's the source." Again, you can find this information, but it's scattered in academic PDFs, diocesan history websites, Wikipedia, and a few general US Catholic history books.

So I built the thing I wanted to already exist. First Mass.net is a crowdsourced, source linked map and timeline of the first documented Catholic Mass in every place that eventually became part of the United States, states and territories both. Watch the dots denoting a First Mass bloom across the landmass in chronological order: Puerto Rico in 1509, Kansas in 1541 with Fray Juan de Padilla, California in 1602 at Point Loma during the Vizcaino expedition, Maryland in 1634, French missionary Masses in western New York and further inland.

I hope to create a one-stop shop for the first mass said in every county in what was to become the United States of America.

What I get out of this

Selfishly, this will be a permanent research tool for my own writing, instead of re-Googling the same primary sources every time I want to write about a mission or a martyr. Less selfishly, I think there's real value in making this legible to people who aren't already deep in the weeds. I want the teacher looking for resources to be able to use this site, or for a Catholic to come across it and discover in a moment of serendipity that mass was said in their area 100 years before the date on the founding plaque at their city hall. There's something satisfying about building infrastructure instead of just opinion.

Also, I built it to encourage Catholics in 2026 to explore and understand more about the history of their own local communities and parishes. I hope they browse the site, find a first mass said near them, and think about the Catholics who stepped in the place they live before them, ponder their story and how they lived their faith.

The Turnerian problem

I also built it to pick at a scab that bothers me. That scab is the fact that American historical memory has been loudly and with great force, almost administratively, set in stone as an east to west story. It starts out in the Northeast you see, with Puritan New England as the moral nursery of the nation, and in the south, with its agrarian and slave roots. Catholics in this classic telling arrive later as an immigrant complication to be assimilated or tolerated. The west, if it's mentioned at all, is portrayed as the target of Manifest Destiny, the ultimate goal of the project, the great Anglo frontier.

Catholics already existing out west? Forget about it. If Catholic history gets mentioned at all, it's folded into a separate bin labeled "Spanish colonial" or "mission era," treated as prologue, someone else's history, interesting the way ruins are interesting, not treated as American history with a capital A. And French Catholic efforts, from the Gulf Coast up through the Great Lakes, barely register either.

This is a choice others made in how we teach history, a choice made by 19th and 20th century historians working from an East Coast, Anglo-Protestant vantage point (looking at Frederick Jackson Turner in particular), and it has consequences. It lets people talk about "America's Christian founding" without mentioning Catholicism. In fact, it erases America's deep Catholic roots. It erases the fact that Catholic sacramental life, in Latin, under three different European crowns, was already established in significant parts of what's now the US. And it teaches Western, Southwestern, and Gulf Coast Catholics, especially Hispanic, Native, and Creole Catholics, that their communities' religious history is a separate, secondary track. It's regional color, not the main line of the American story.

I don't think that's true, and I don't think it's innocent.

What I'm hoping First Mass does instead

I want a resource where a Mass said at Point Loma in 1602, a Mass said along the Mississippi under French sponsorship, and a Mass said in Maryland in 1634 all sit on the same table, sorted the same way, weighted the same way. Not two or three separate stories on parallel tracks, "colonial Spanish," "colonial French," and "American founding," but one story, told chronologically, the way it actually happened.

You hit the play button on the map, and it shows you visually where mass was said and when.

Maryland's founding still matters, obviously, it's in the dataset. The point is to stop letting it stand in, by default, for the whole country's Catholic origin story when it's demonstrably not the earliest thread, and often not even the most consequential one for the largest Catholic populations we have today.

The site is live now at firstmass.net. A handful of seed entries so far, more going up as I verify sources, and a submission form if you know of a documented first Mass in your county, diocese, or territory that isn't on there yet. Diocesan archivists, local historians, parish archivists, antiquarians and amateurs, I'm looking at you! Every approved entry gets sourced and dated properly, disputed claims get flagged as disputed rather than smoothed over, and the whole dataset stays public and growing.

This isn't a replacement for the Catholic West history I've been writing. I hope it will be the skeleton the writing hangs on, and an open invitation to fill in more of the American Catholic story.

Go check it out. Submit something if you've got it. Let's build a fuller picture of the Catholic story in America than the one we inherited!

Thanks for reading!
