What they actually mean

"Going somewhere else to serve and share faith — a week, a year, or forever."

The Lighter Side

A week abroad building a wall that the locals could have built faster, funded by a spaghetti dinner. Everyone comes home changed. The wall is fine.

The longer version

What it means

Missions is the church's work beyond itself: sending people to share the Christian message and serve human need in places where the church is absent or small, or where need is great. Missionaries are the long-term version — people who move to another country or culture, learn the language, and stay for years or decades, doing everything from church planting and Bible translation to medicine, education, and relief work. A mission trip is the short-term version — a team from a church spends a week or two helping a missionary or a local church, building, teaching, serving.

A church's "missions program" typically means the missionaries it supports financially and prays for, plus the trips it sends.

Why people say it

Christians believe Jesus told them to go to all nations, and missions is obedience to that. It's also love: the conviction that the gospel is good news for everyone, and that need anywhere is the church's concern. For churches, supporting missionaries connects a congregation in Ohio to the world; for individuals, a mission trip is often the first time faith becomes concrete. The critiques of short-term missions come from inside the church precisely because Christians care about doing it well.

How to respond

If someone tells you they're going on a mission trip, they're excited and probably fundraising; "what will you be doing?" is a fair question, and the honest ones will tell you. If a friend is a missionary or supports one, they're involved in something long and costly. If you have concerns about missions — cultural, historical — say so; thoughtful Christians share many of them and can tell you how the field has changed.

If you hear it in different churches

Evangelical, Baptist, and Pentecostal churches make missions central — mission boards, "missions Sunday," a wall of missionary photos. Catholics have a vast missionary history (Jesuits, Franciscans, Maryknoll) and speak of "mission" and "evangelization." Orthodox mission is smaller but real. Mainline Protestants emphasize partnership, development, and justice alongside evangelism. Nearly all churches send short-term teams now.

Where does “Missions” come from?

Jesus' Great Commission and Acts 1:8 — "to the ends of the earth" — are the mandate; Paul is the first missionary. The church's expansion across the Roman world, then Europe (Patrick, Boniface), then the globe through Catholic orders in the 1500s, is mission history. The modern Protestant missionary movement dates from William Carey's departure for India in 1793; the 1800s were the "great century" of missions, and Hudson Taylor's China Inland Mission (1865) pioneered "faith missions." Short-term mission trips are a product of the 1960s–80s, made possible by cheap air travel, and exploded through youth ministry in the 1990s.

Good to know

"Missionary" is a serious, long-term calling; "mission trip" is short-term, usually one to two weeks, and often involves construction, medical clinics, kids' programs, or supporting long-term missionaries. Short-term trips are loved and also critiqued inside the church (see the lighter side) — the best ones are planned with local partners, not for them. "Missional" is a newer adjective meaning "oriented toward mission where you already live."

Common questions

What's the difference between a missionary and a mission trip?+

A missionary lives and works in another culture long-term, often for years. A mission trip is a short team visit, usually one to two weeks.

Are mission trips actually helpful?+

Sometimes very; sometimes more for the visitors than the hosts. Churches increasingly plan trips with local partners, focus on relationships, and send money where that helps more. The debate is lively inside the church.

How are missionaries paid?+

Usually by churches and individuals who commit to monthly support — "support raising" — sometimes through a denominational board.
