Missionary, Expat, Professional, or Tentmaker? Understanding the Differences
At a missions conference, a young business administrator mentions he's moving to Vietnam for work. Someone asks, out of genuine curiosity, whether he's going as a missionary. He hesitates, because it isn't quite that, but it isn't just an ordinary job either, and the question, which seems simple enough, catches him without a ready answer.
That hesitation is common: there's a lack of clear, biblically grounded language to describe the different ways of living out the Christian faith abroad. Without these definitions, people end up borrowing whichever label seems closest, even when it doesn't quite describe what they're actually living, which confuses expectations, both for the person themselves and for the church and community around them. It's worth separating out four profiles that, whilst they sometimes overlap in practice, describe genuinely distinct realities.
What you need to know
Traditional missionary, expat, Christian professional and tentmaker are different categories, even though they sometimes overlap.
The difference between them lies mainly in strategic intentionality, not in geography or profession itself.
Tentmaker includes professionals, but also students (international student ministry) and entrepreneurs (Business as Mission).
These categories aren't fixed: someone can move from one profile to another over time.
Naming precisely where you stand has practical consequences, including the kind of spiritual support your church is able to offer.
The traditional missionary
This is someone formally sent by a church or missionary agency, generally with financial support from partner donors, a publicly recognised calling, and a declared focus on ministry, evangelism or church planting as their primary occupation. The work is, in essence, the ministry itself: preaching, discipling, training local leaders. This model remains entirely valid and necessary, and it simply isn't the only path available, especially where religious visas are no longer being issued.
The expat
The expat is someone who moved country for professional, family or economic reasons, without that move having grown out of any specific missional intention. They may or may not be a Christian, and if they are, they may live out their faith sincerely day to day, but without the move abroad having been motivated, even in part, by a purpose of witness or reaching a particular group of people.
There's nothing wrong with that, of course. Not every Christian living abroad needs a missionary strategy behind their move. When someone describes themselves as a tentmaker simply because they're a Christian living overseas, with no intentionality beyond that, there's a clear mismatch between the description and the reality being lived.
The Christian professional
This is the Christian who works in another country, or even in their own, with integrity and genuine faith, but without their vocation having been chosen, or lived out, as a deliberate strategy of missional presence. They pray before meals, are honest in business, perhaps even share their faith when a natural opportunity arises, and that is already, in many ways, a faithful witness. The difference from the tentmaker lies precisely in strategic intentionality: the Christian professional didn't choose that country, that sector or that timing with missional reach in mind, whereas the tentmaker did.
The tentmaker
The tentmaker deliberately uses their professional calling as the means and context for strategic Christian presence in a cross-cultural setting, often in places where more traditional forms of mission simply have no access. The choice of country, profession and timing of the move are all made with a purpose that goes beyond the CV or the career opportunity, and it's precisely this layer of intentionality that makes them, in terms of commitment and calling, a missionary in every sense, even when recognised by the host culture as simply a good professional.
This category is broader than it first appears, and also includes students who live out their faith intentionally at universities abroad, commonly referred to in mission circles as international student ministry, and entrepreneurs who build businesses with both a profit and a missional purpose, a model known today as Business as Mission (BAM). The common thread running through all these cases is always the same: a vocation, pursued with excellence, deliberately placed at the service of a greater purpose.
This doesn't mean the tentmaker is a missionary in disguise, pretending to be a professional. The work needs to be real, serious, well done, and it's precisely that seriousness that sets them apart from both the expat and the ordinary Christian professional.
The lines aren't always clear-cut
It's worth acknowledging that these definitions don't form entirely separate categories. Someone can start out as a simple Christian professional and, over the years, grow into a more strategic awareness of their presence in that place, becoming, in practice, a tentmaker without having planned it that way from the outset. Others go the opposite way: they start with strong intentionality and, over time, let routine absorb the original purpose.
Underneath all of this sits a simple biblical principle: different callings, lived out in different situations, are equally legitimate. Paul tells the Corinthians that "each person should live as a believer in whatever situation the Lord has assigned to them, just as God has called them" (1 Corinthians 7:17, NIV). That single line does a lot of work here. It means the calling itself, not the label attached to it, is what carries weight before God.
Daniel, in the Old Testament, illustrates this complexity well. He wasn't sent to Babylon as a missionary, but taken there as an exile, and rose to a position of very high standing in government, where he lived with visible integrity and faith for decades, influencing the court of more than one empire without ever giving up his public office to "devote himself to religion full time". His professional excellence was such that even his political rivals came up empty-handed when they went looking for a case against him: "the administrators and the satraps tried to find grounds for charges against Daniel in his conduct of government affairs, but they were unable to do so. They could find no corruption in him, because he was trustworthy and neither corrupt nor negligent" (Daniel 6:4, NIV). His professional calling was, in itself, the stage for his witness.
In closing
Understanding these differences has practical consequences. A church that doesn't distinguish between these profiles will, without realising it, hold everyone to the same standard, expecting expats to take on ministry involvement that was never part of their calling, or denying tentmakers the spiritual support their strategic vocation genuinely requires.
For anyone caught in the middle of this confusion, trying to work out where they fit, the first step is simply to name, honestly, where they are right now. There's no need to already have every answer, but it is necessary to stop using borrowed labels that don't match the reality being lived.
In the next article, we'll take a step back and look at the bigger picture: why traditional mission models, on their own, are no longer enough to reach the world as it is today, and what that means for anyone thinking through how to position themselves. Before that, if you'd like a refresher on the foundations, it's worth revisiting what tentmaking actually is.
Frequently asked questions
What's the difference between a traditional missionary and a tentmaker? The traditional missionary is formally sent, with structured financial support and ministry as their primary occupation. The tentmaker lives out their mission through a real and intentional professional calling, often in a context where the traditional model simply wouldn't have access.
Is every Christian living abroad a tentmaker? No. A Christian may live abroad for professional or family reasons, without that having grown out of any missional intention. In that case, they fit better as an expat or Christian professional, not as a tentmaker.
Can someone move from one type to another? Yes. These categories aren't fixed. It's common for someone to start out as an ordinary Christian professional and, over time, grow into a more intentional and strategic presence, becoming, in practice, a tentmaker.
Is a tentmaker only someone with a formal job abroad? No. The category also includes international students living out their faith intentionally, and entrepreneurs building businesses with a dual purpose, profit and mission.
If you recognised yourself in the description of the tentmaker, but still aren't sure how to take the first steps in that direction, GO Experience was designed for exactly this moment.
