In churches across Europe, Persian-speaking believers come faithfully every week and often catch only part of what is said. MulingStream started with one of them. Here is what a Persian speaker gets today: the sermon live on their own phone, in Persian, read right to left or heard aloud.
In many churches across Europe there are people who arrive early, sing with their whole heart, and then sit through the sermon catching one word in three.
Some of them are Persian speakers. Iranians and Afghans, students and grandparents, young families and people who came on their own. Many came to faith as adults, some from a Muslim background, often a long way from where they grew up. They have found a church in Denmark, Germany, Sweden, the Netherlands or the United Kingdom, and they love it. The language of that church is simply not the language of their heart.
Churches meet this in different ways. Some host a Persian fellowship in their building on a Sunday afternoon. Some have a faithful volunteer who whispers a translation, or an interpreter on a headset feed. Many simply welcome Persian speakers into the main service and hope that enough of the message comes through.
It is good that they are there. It is hard that so much of what is said does not reach them. A sermon is not a news report. It is full of Scripture, stories, names and the small turns of phrase that make a preacher's point, and a guest who follows only the outline misses most of what makes it land.
MulingStream began with exactly this, in a church in Denmark, on Sunday 11 August 2024. Our founder's wife's heart language is Persian. That morning the church offered a Persian interpreter feed, and it could not keep up with the preacher: sentences arrived late, some never arrived, and the parts that did arrive did not always fit together. She tried to follow it, and then she switched it off. The full story is in our journal, how Mulingai started.
She came to hear the Word, and the language stood in the way.
Everything we have built since comes back to that Sunday. So Persian is not one language among many on our list. It is the first one we built for.
The preacher speaks as usual, into a laptop or tablet running MulingStream in the browser. The Persian speaker takes out the phone already in their pocket, scans the QR code on the screen or opens the link the church shared, and chooses Persian. There is no app to install and no account to make.
From then on the sermon arrives on their phone, live, in Persian, while the preacher is still speaking. They can read it, or they can listen to it in a Persian voice through an earbud, whichever suits them. Many people do both: listen, and glance down when a name or a verse goes by.
Nobody else in the room has to know. There is no headset handed out at the door and no corner where the people who need help sit together. The person reading Persian on their phone looks like everybody else reading their Bible app.
Persian is written from right to left, and a screen that forgets this is tiring to read. Words land in the wrong place, punctuation wanders to the wrong end of the line, and the eye keeps having to start again.
On MulingStream, Persian captions are laid out right to left, aligned the way a Persian reader expects, in the Persian script. It sounds like a small thing. For someone reading for forty minutes, it is the difference between following the sermon and fighting the screen.
It also works the other way round. Persian can be the language that is spoken, not only the one that is read. When a Persian-speaking pastor or elder brings a word, a testimony or a sermon, the Danish, German or English-speaking members of the church can follow it on their own phones in their own language.
That matters more than it first seems. A church with a Persian fellowship often has two congregations that love each other and rarely understand each other. At a joint service, a baptism or a shared meal with a short talk, everyone can follow everyone.
Setting this up takes about two minutes: sign up, add the languages your guests need, share the link or the QR code, and start speaking. There is nothing to rent and no booth to build, and the laptop that already runs the slides is usually enough. More on what a church does on the day is on how it works for leaders, and what the guest sees is on how it works for listeners.
MulingStream does not replace anyone's ministry. If your church has a faithful interpreter, it sits alongside them: it covers the Sundays they are away, the languages they do not speak, and the guest who would rather read than listen. New accounts start with a free, generous trial, so you can try it on an ordinary Sunday before deciding anything.
Persian is one of 200+ languages on MulingStream, and you can see them all, with what each one offers, on our languages page. Persian has its own page at Persian on MulingStream.
Since 19 March 2026, Smart Translation builds whole sentences from what the preacher means, not only from the words, and Smart Hints add a short note under a line when something would not travel on its own. When the preacher quotes or names a Bible verse, a Persian listener sees the reference and the verse itself from a widely used Persian Bible translation, so a guest who does not know the passage by heart reads the words everybody else in the room already knows.
Since 5 August 2026, MulingStream itself speaks Persian: the website at mulingstream.com/fa and the screens a listener uses on their phone, laid out right to left. On the same day Dari, the Persian of Afghanistan, joined the list as its own language. Dari listeners read the sermon as text in Dari; there is no Dari voice. More about the difference between the two, and why it matters in a congregation, is on Dari on MulingStream.
Since 2 September 2026, churches can use MulingStream with church passes, and every church gets its first two services free, so a Persian-speaking guest can follow a whole Sunday before the church decides anything. What each pass covers is on pricing for churches.
