In 1585, the Vatican was packed.
Hundreds of cannons fired in salute.
Crowds filled St. Peter’s Square to catch a glimpse of four teenage boys who had just completed one of the most improbable journeys in history — from feudal Japan to the heart of Rome.
When the boys entered the papal chambers, an 84-year-old man wept.
Not politely. Not ceremonially.
He wept like someone who had been waiting a very long time for something to finally arrive.
That man was Pope Gregory XIII.

I came across this story while reading about the Jesuit missions in Japan. I wasn’t looking for a lesson in audience-building. But somewhere between the 16th century and my own fumbling attempts to grow a newsletter, I found one — sharper than anything I’ve read in a marketing book.
Most advice for growing a Substack sounds reasonable.
Post consistently. Find your niche. Optimize your headline. And yet most of us who follow that advice still feel, at some point, like we’re sending letters into a void.
I think I know why.
And I think a Jesuit missionary named Alessandro Valignano figured it out four hundred years before we did.
The Mistake Almost Every Writer Makes — Including Me
Before Valignano, there was Father Cabral.
Cabral arrived in Japan in the 1570s as head of the Jesuit mission. He was earnest, hardworking, and genuinely convinced that what he had to offer was worth receiving. He was also failing. Not because the message was wrong. But because Cabral had made a quiet assumption: that the people he wanted to reach should adapt to him.
He made little effort to learn the language. He dismissed local customs. He treated the gap between his world and theirs as a problem for them to solve.
When I read this, I felt uncomfortably seen.
Because I’ve done this too.
I’ve decided what I wanted to write about, chosen a format I liked, and then wondered why it wasn’t landing. The implicit assumption underneath all of it: I have something valuable. People should find me.
That’s the Cabral trap. It’s not arrogance, exactly. It’s a posture. A subtle one. And it is extraordinarily common.
Valignano arrived in Japan in 1579 as the Visitor of the Jesuit missions in Asia — essentially a global auditor of what was and wasn’t working. He observed Cabral’s approach and reached a simple conclusion: the problem wasn’t Japan.
The problem was the posture.
He removed Cabral and issued new instructions.
The missionaries were to learn Japanese. Study local customs. Treat Japanese culture not as an obstacle but as the actual terrain they were working in.
Valignano himself wrote that the Japanese language was, as far as he knew, the finest in the world — richer in vocabulary than Latin, more precise in expressing thought.
For a 16th-century European to write this about a non-Western language was, as one scholar later noted, close to miraculous.
He wasn’t performing respect. He had genuinely arrived at it.
The results were not subtle.
Within decades, more than 300,000 people in Kyushu had converted — over 30% of the regional population.
Same message. Same mission. Completely different posture.
“If you’re writing for everyone, you’re writing for no one.”— Seth Godin
Seth Godin — a writer who has spent thirty years thinking about how ideas spread — calls this finding your Smallest Viable Audience.
Not a demographic. A psychology. A specific set of beliefs and fears held by a specific kind of person. Depth of resonance with a few, he argues, is worth more than shallow reach with many.
Valignano never read Godin. But he understood this completely.
I think of the shift he made as moving from broadcast to resonance. From “I have something to give you” to “I want to understand you well enough that what I give actually lands.”
Simple to describe. Remarkably hard to do.
Three Things I’m Still Learning From a 16th-Century Missionary
What struck me most, reading about Valignano, was not the strategy.
It was the sequence. He didn’t start with reach. He started with understanding.
Here’s what I keep coming back to.
I. One reader before thousands
Valignano didn’t try to reach Japan. He tried to reach specific people — particular lords, particular courts. He understood that if the right few were moved, the movement would follow.
I’ve started asking myself a simpler version of this: who is the one person I’m actually writing for? Not a persona. A person. Specific enough that I could write them a letter. What do they believe that most people around them don’t? What would make them forward something I wrote to someone they respect?
Something worth trying: Finish this sentence — “I write for someone who believes ___ and is quietly afraid of ___.” If you can’t, that’s probably the work.
II. Learn the language before you speak
Valignano required his missionaries to learn Japanese before they were permitted to preach. Not to become fluent. To demonstrate, through the effort itself, that they took the other person seriously.
In writing, I’ve found this means paying attention to how my reader actually talks about the thing I’m writing about — not how I talk about it.
The goal isn’t to mimic them. It’s to give them the words for something they already feel but haven’t quite been able to say.
Godin has a version of this test: would someone reading this want to share it with forty colleagues? Not because it’s clever. Because it says something they’ve been trying to say for years.
III. Send the letter, then go back to work
Here is the detail I keep returning to most.
Valignano organized the entire mission to Rome.
He arranged for the boys to travel across two continents, to be received by kings and cardinals, to stand before the Pope. And then he went back to Asia.
He was not in the room when the Pope wept.
He never saw the moment his work landed.
Most of the moments your writing lands, you won’t see either.
Someone will read something you wrote months ago and feel, for the first time, that they are not alone in whatever they’re carrying. You’ll never know.
This isn’t a consolation. It’s the nature of the work.
· · ·
The Pope wept because something had finally arrived that he had almost stopped believing would come.
The four boys were not, in themselves, the miracle.
The miracle was the years of quiet, unglamorous work that made it possible for the right thing to reach the right person at the right moment.
That’s still, four hundred and forty years later, the only strategy I’ve found that actually works.
Not more posts. Not better headlines.
Understanding one person deeply enough that what you write lands. ■
