Hello, my friend. Come in, come in. I'm so glad you're back.
Last time, we spent our hours with Phoebe, my dear Phoebe, the woman who carried a letter across the sea and was trusted to explain it when she arrived. You may remember where I found her again: high in the glass of Trinity College Chapel in Cambridge, her face glowing in the afternoon light.
Well. I have a small confession to make.
Phoebe wasn't alone in that window. Standing right beside her, in the very same panel of colored glass, was another woman I loved. Another friend who made my first-century world warmer than it had any right to be. And I walked right past her to tell you Phoebe's story.
She has been very patient with me. She always was.
Today, it's her turn.
So settle in. Pour yourself something warm. We're going to a river.
It's a warm morning in northern Greece, and the plane trees are doing that thing where the light comes through in coins.
I'm sitting on a stone bench beside a little stream. It isn't much of a river, honestly. You could toss a pebble across it without trying. The water is clear and quick and very cold, and it runs past a small open-air baptistry built of pale stone, with rows of seats curving around it like a quiet amphitheater. The village nearby is called Lydia now. They named it after her.
The first bus pulls in a little after nine.
Out step a choir from Lagos, still humming something from the ride, the women in bright green and gold. Behind them a Korean family, a grandfather with a walking stick and three grandchildren who immediately take off their shoes. Then a group of Romanian grandmothers in dark headscarves, who walk straight to the water and cross themselves before anyone has told them where to stand. A young couple from Brazil holding hands. A man from Ohio with a very large camera and a very kind face.
By ten o'clock the bank is lined with shoes. Sandals, sneakers, sensible black leather, a pair of tiny pink ones with lights in the heels.
And one by one, they step into the same cold water.
I hear prayers in Yoruba, in Korean, in Romanian, in Portuguese. I hear a little boy gasp at the cold and his mother laugh. I hear the choir start to sing, low at first, and then the Romanian grandmothers join in without knowing the words, just holding the notes. None of them came together. Most of them will never see each other again. But for one morning, they are all standing in the same stream, getting their feet wet for the same reason.
I love this place. I come back more often than I'd admit.
Because I remember when it looked very different.
I remember when there were only a few of us here. No stone benches. No buses. Just a grassy bank outside the city gate, a Sabbath morning, and a small circle of women who came to pray because there was nowhere else in town for them to do it.
And among them, a merchant with purple stains on her fingers who always sat a little closer to the water than everyone else.
Her name, or at least what everyone called her, was Lydia.
Let me take you back. It's around the year 50, give or take, and Philippi is a very pleased-with-itself little city.
About ninety years earlier, two Roman armies had fought on the plain just outside its walls, a famous battle that decided who would rule Rome. When it was over, the winners needed somewhere to put their old soldiers. So they settled them here, gave the town a long Latin name, and declared it a Roman colony. That meant Roman law, Roman officials in Roman robes, Latin carved over the doorways. It was a little piece of Rome dropped into the hills of Macedonia, and it never let you forget it.
It also sat on the Via Egnatia, the great road that ran across the top of Greece, linking east to west. Everyone came through Philippi eventually: soldiers, traders, slaves, travelers. It was a crossroads that liked to pretend it was a fortress.
Lydia didn't come from there. She came from Thyatira, across the Aegean Sea in Asia Minor, a city famous for one thing above all others: dye. Nobody in Philippi used her real name much. They called her the Lydian, because that's where she was from, the way you might call someone "the Texan" at a party in Boston. She never seemed to mind. I think she rather liked it.
She sold purple.
Now, you have to understand what purple meant back then. It was the color of emperors and senators. Real imperial purple came from crushed sea snails, thousands of them for a single robe, and it cost more than gold.
Don't tell anyone, but Lydia's purple mostly didn't come from snails. The dyers of Thyatira had learned to coax a rich red-purple out of the root of the madder plant. It was beautiful and far more affordable, and it let a prosperous family in Philippi feel a little bit like the emperor. She was a very clever merchant. She knew exactly what people wanted to feel.
She ran her own household, too. There was no husband that anyone mentioned, and nobody told her what to do. In a proud Roman town, a foreign woman managing her own business and her own home was the kind of thing people noticed. Lydia noticed them noticing, and carried on.
On the Sabbath, she went down to the river.
Lydia was what people called a God-fearer. She wasn't Jewish by birth, but she'd been drawn to the one God of the Jewish people, and she prayed to Him. Philippi didn't have a synagogue; there weren't enough Jewish men in town to form one. So a few women met outside the city gate by the water, where it was quiet. That was where I first sat beside her, watching her wring purple out of the hem of her sleeve.
One Sabbath, some strangers came walking down the path. There were four of them, dusty from the road up from the harbor: a small, intense man named Paul; his companion Silas; young Timothy; and a physician named Luke, who, I'll point out, is the one who later wrote all this down. You can tell when he joined the story, because he suddenly starts saying "we."
They sat down with the women and began to talk.
I watched Lydia while they did. She wasn't the sort to be swept away by anybody. She'd haggled with sea captains. But that morning she went very still, the way you do when someone says the thing you've been waiting years to hear and didn't know it. She listened. Really listened. It was a lovely thing to see.
Before long, she and her whole household were baptized right there in that cold little stream.
And then, before the water had even dried, she turned to those four tired men and said, "If you believe I'm truly faithful, come and stay at my house."
They hesitated. Of course they did.
Luke writes, a little sheepishly, that she persuaded them.
I was there. "Persuaded" is a very polite word for it.
For a while, Lydia's house was the happiest place in Philippi. The travelers stayed on. Every Sabbath they went down to the river, and every evening they came back to her table. People started drifting in to listen. It was a good season.
What happened next, I'll tell you the way I first heard it: from Paul and Silas themselves, bruised and exhausted, a few days later. It's their story, and I've always tried to honor it as theirs.
There was a girl in Philippi.
She was enslaved, owned by a group of men who'd found a way to make her profitable. People believed she had a spirit that could see the future, and they paid to hear her speak. So her owners rented out her voice the way you'd rent out a mule. She was young. I don't think anyone had ever asked her what she wanted.
When Paul and his friends walked through town, she started following them. Day after day, she trailed behind them through the streets, calling out, "These men are servants of the Most High God! They're telling you the way to be saved!" Over and over, for days.
Think about that for a moment. Everything she said was true. And nobody was listening to her. They were listening to what her owners could sell.
Paul put up with it for a long time. Then one day, weary and troubled, he turned around and commanded the spirit to leave her.
And she went quiet.
You'd hope someone would have asked how she was. Instead, her owners looked at her and saw only that their income was gone. They didn't blame the spirit; they blamed the strangers. They dragged Paul and Silas into the marketplace in front of the Roman magistrates and shouted that these foreigners were stirring up trouble and teaching customs no proper Roman should follow. A crowd gathered, as crowds do. The officials had the two men stripped, beaten with rods, and thrown into the deepest part of the jail with their feet locked in stocks.
That's when the story turns toward the jailer.
That night, Paul and Silas were singing. Imagine it: bleeding and chained, singing hymns in the dark while the other prisoners listened. Around midnight the ground shook hard enough to throw open the doors. The jailer, a Roman functionary who'd simply been doing his job, was sure his life was over. Instead he found his prisoners still there, calling to him not to be afraid. Before dawn, this man who'd locked them up was washing their wounds with his own hands. He brought them into his house, fed them, and he and his whole family were baptized.
In the morning, the magistrates discovered they had beaten two Roman citizens without a trial, which was very much against the rules. Embarrassed, they came in person and politely asked them to please leave town.
And where did Paul and Silas go first?
Straight to Lydia's.
Luke says that when they got there, the brothers and sisters were gathered, and they encouraged them all before setting off down the road.
Now, here I have to be honest with you, because you're my friend. I can't tell you for certain whether the jailer ever sat in Lydia's courtyard. And the girl, I've searched my memory more times than I can count. I can't recall her there. I truly don't know.
But I know what those three people meant together. A free foreign businesswoman who dealt in the color of emperors. A girl whose owners valued her voice but never her. A servant of Rome who kept the keys. That was Philippi, the whole city in three faces: the ones with means, the ones without, and the ones who kept order between them.
In a town where everyone knew exactly where they ranked, Lydia had built a room where your rank at the door didn't decide your seat at the table.
That was the new thing. Not an idea, just a household. Oil lamps and bread and people who had no business being together, being together anyway.
Paul and Silas left Philippi that same day, but they never really left Lydia's house.
The little community that gathered there became the one Paul loved most. Years later, when he was in prison again, far away, he wrote them a letter, and it's the warmest thing he ever wrote. He tells them he thanks God every time he remembers them. He tells them that in the early days, when he first set out, they were the only community that shared with him in giving and receiving. The only one. That generosity started somewhere, and I know which dining room it started in.
In that same letter, he mentions two women by name, Euodia and Syntyche. He calls them people who struggled beside him in the work. They'd been having a disagreement, and he gently asks them to make peace. I smiled when I read that. Of course they disagreed. Put strong, different people in one room and they will. The point was that they were still in the same room.
That was Lydia's real gift to the story. Not a sermon. A floor plan.
For the next few centuries, the new faith spread almost entirely through homes like hers: living rooms, courtyards, and rooftops where people from every rank of society ate from the same bread. The Eastern churches would later give Lydia the title "Equal to the Apostles," which I think would have made her laugh and then quietly insist on feeding you.
And I've watched that pattern appear again and again, in places that never heard her name. In the Sikh kitchens of Punjab, where kings and beggars sit on the same floor and eat the same meal. In plain Quaker meetinghouses, where no seat was higher than another.
Different walls. The same open door.
Let's go back to that stream for a moment. The one with all the shoes on the bank.
When I sit there now and watch the buses pull in, I sometimes think Lydia would hardly believe it. Lagos and Seoul and Bucharest and São Paulo, all standing in her cold little river. In her day, a gathering like that would have taken a lifetime of roads and ships and luck. Now it happens before lunch on an ordinary Tuesday.
And it isn't just there. It's everywhere you go.
Walk into almost any school today and listen. Stand in line at a grocery store, sit in a hospital waiting room, scroll through the faces on your phone. The world Lydia had to gather into one house, one guest at a time, is simply the world you live in now. You didn't have to go looking for it. It came to you. People of every color, language, and faith live on your street, in your feed, and in the next seat on the bus.
That part is already done. Diversity isn't a goal anymore; it's the water we swim in.
But you and I both know that being in the same place isn't the same as being together. Philippi was a crossroads long before Lydia opened her door. People had been passing each other on that road for generations, the merchant, the slave, the soldier, without ever once sitting down at the same table.
Unity is the other half. And it has never happened by accident.
Here's something Lydia knew in her hands. When you put wool, linen, and silk into the same vat of purple, they don't come out the same. Each takes the color in its own way. The wool goes deep and soft. The silk shines. The linen holds on quietly. And when you weave those threads together, you get something richer than any one of them could be alone.
That's what unity is. Not everyone dyed the same shade. A pattern that needs every color to be complete.
I've been watching this tapestry for a very long time, my friend. And I'll tell you something with all the certainty I have: the pattern is coming together. You can see it in the weave closest to us, the threads crossing where they never crossed before, reaching across oceans and old hatreds. The human family is growing into itself. That's where this is all heading. It's already on its way.
But a tapestry doesn't weave itself.
Every thread is placed by someone's hand. The oneness of people doesn't arrive as a headline one morning. It arrives the way it arrived in Philippi: in a particular room, around a particular table, because a particular person decided to say, "Come in. Stay. There's room."
That's what believing in a better world looks like. Not waiting for it. Setting a table for it.
It looks like the neighbor who learns how to say "welcome" in the language of the family that just moved in. It looks like the coach who makes sure the new kid gets passed the ball. It looks like a community center where the potluck has six kinds of rice and nobody minds. It looks like someone noticing who isn't in the room yet, and quietly going to find them.
Lydia didn't solve Philippi. She didn't end slavery or change Roman law. What she did was smaller and, I think, more powerful. She made one place where the city's walls didn't reach.
There are an infinite number of ways to build a world where every person belongs. They all start the same way: with someone opening a door.
The pilgrims in that stream came from everywhere. They'll go back to everywhere.
I hope they take her door with them.
Now let me ask you something, just between us.
Think about your own rooms for a minute. Your kitchen table, your lunch table, the group chat, the circle of people you sit with on Friday nights. Who comes through those doors easily? Who has been coming for years?
And who never has?
I don't ask that to make you feel guilty. Most of us build our rooms without meaning to. We invite the people who are easy to invite, the ones who already talk like us and laugh at the same things. That's human. Lydia's first guests were people who had come to the same riverbank to pray. It's where everyone starts.
But the crossroads is always nearby. Every town has one. Maybe it's the person at work who eats alone. Maybe it's the family at the end of the street whose names you've never learned. Maybe it's someone you've been a little afraid of, or a little unsure about, or simply never thought to look at twice.
I'll tell you what I still think about.
That girl.
Her voice was the most valuable thing about her, as far as the world was concerned. And the moment it went quiet, she vanished from the story. No one wrote down her name. No one wrote down where she went. I've wondered for almost two thousand years whether anyone ever took her by the hand and walked her up to Lydia's door.
I hope they did. I truly don't know.
So maybe that's the question I'll leave with you. Not "Is my door open?" Most of us would say yes.
But who in your life might you not be sure ever made it inside?
And what would it take to go find them?
Next time, we're traveling a long way east and up, very high up, onto the roof of the world.
I want you to meet Je Tsongkhapa.
He was born in 1357 in a far corner of Tibet, and at sixteen he set off on foot toward the great monasteries of central Tibet, hungry to learn everything. And I do mean everything. He studied with teacher after teacher, and he became famous for a surprising idea: that faith and careful reasoning were meant to walk together. His students didn't just memorize; they argued. They debated in the courtyards, loudly, with a clap of the hands to punctuate every point, testing every idea until it proved itself true.
In 1409, he gathered thousands of people in Lhasa for a great festival of prayer that is still remembered today. And the school of thought that grew from his teaching would one day give Tibet its Dalai Lamas.
I'll tell you what he was like when no one was watching. You'll like him. He asked very good questions.
But before we go, one last look back.
I still have a scrap of Lydia's cloth, you know. Madder purple, a little faded now. She pressed it into my hand one evening as the lamps were being lit and the courtyard was filling up with people who didn't belong together, and did.
I keep it as a reminder of something she knew better than anyone. The beauty was never in one color. It was in all the different threads that were willing to take it in, each in its own way, and be woven into the same cloth.
So open a door this week, my friend. Set one more place. Go find someone you haven't yet.
The pattern is waiting for them.
Much love.
I am, Harmonia.
