This resource introduces a biblical and practical definition of what it means to be a sending church—developed by the Upstream Collective to help churches send well. Drawing from the example of the church at Antioch, it unpacks key components of the definition and invites leaders to reflect on their church’s current practices. Use it as a conversation starter with your team and a launch point into deeper engagement with with our book, The Sending Church Defined.

The Upstream Collective was born from a simple but pressing conviction: the local church must reclaim its central role in God’s global mission. From our earliest days, we have sought to empower churches not only to care about missions, but to send well—to be deeply involved in raising up, sending out, sustaining, and receiving back their own people for the sake of the gospel.

As we began equipping churches, one thing quickly became clear: we needed shared language. “Sending church” was a term already in circulation, but its meaning varied widely. For some, it simply meant sending money. For others, it meant short-term missions teams. But we envisioned something deeper, more holistic, more biblically rooted. That led us to a fundamental question: What exactly is a sending church?

To answer that, we turned to Scripture. While many passages give insight into the mission of the church, one stood out as a vivid example—the church at Antioch. We read in Acts 13:1-13,

Now there were in the church at Antioch prophets and teachers, Barnabas, Simeon who was called Niger, Lucius of Cyrene, Manaen a lifelong friend of Herod the tetrarch, and Saul. While they were worshiping the Lord and fasting, the Holy Spirit said, ‘Set apart for me Barnabas and Saul for the work to which I have called them.’ Then after fasting and praying they laid their hands on them and sent them off.

In these few verses, we find a powerful expression of the sending God and his sent people. Antioch was not a passive church waiting for mission to happen. They were actively seeking the Lord in worship and fasting. They were sensitive to the voice of the Spirit. And when God called, they responded—not by holding on to their most gifted leaders, but by sending them.

This wasn’t a side project for Antioch. It was central to their life together.

They didn’t just send. They sent their best.

This act marked the beginning of Paul’s first missionary journey, which would transform the spiritual landscape of the Gentile world. And the church at Antioch didn’t just send and forget. They stayed connected. After the journey, Paul and Barnabas returned to their sending church:

And when they arrived and gathered the church together, they declared all that God had done with them, and how he had opened a door of faith to the Gentiles. And they remained no little time with the disciples. Acts 14:27–28

Antioch didn’t just commission missionaries—they welcomed them home. They listened. They celebrated. They refreshed them. And as we see in later chapters of Acts, they prepared to send them again.

This is the heartbeat of a church on mission.

Sending isn’t just something the church at Antioch did. It was an expression of who they were. And the same can be true today. Sending is not an add-on to the church’s identity—it’s baked into the DNA of every church that seeks to follow Jesus faithfully. After all, the church itself exists because God sent his Son. We are saved because someone brought the gospel to us. Now, we’re stewards of that same message, compelled to carry it to others.

Antioch is not just an inspiring story from the past—it is a blueprint for churches today.

Defining the Sending Church

With the example of the church at Antioch fresh in mind, we began asking: What would it look like for churches today to embody that same identity? What does it mean—not just aspirationally, but practically—for a church to send its own people well?

We didn’t want to create an abstract theory. We wanted a definition forged in the real world, shaped by Scripture and refined through the lived experiences of faithful churches. So we gathered a collective of sending church leaders—through one-on-one conversations, group forums, and collaborative networks—to listen and learn. What emerged was a shared conviction: healthy sending is both theological and relational, both intentional and communal.

After months of prayer, dialogue, and sharpening, a definition began to take shape—a definition that now serves as the cornerstone of everything we do at the Upstream Collective:

A Sending Church is a local community of Christ-followers who have made a covenant together to be prayerful, deliberate, and proactive in developing, commissioning, and sending their own members both locally and globally, often in partnership with other churches or agencies, and continuing to encourage, support, and advocate for them while making disciples cross-culturally, and upon their return.

Yes, it’s long. Yes, it’s a run-on sentence. But that’s because sending isn’t simple or linear—it’s dynamic, multi-layered, and deeply integrated into the life of a church. Every word in this definition was chosen with purpose.

Before we unpack each part, take a moment to read it again. Let it sit with you. Because this definition isn’t just a description of what some churches do—it’s a vision of what every church can become. Ask yourself: does this resonate with your church’s heart for mission? Does it give language to something you’ve long sensed but couldn’t quite articulate?

Key Observations from the Definition

Our definition of a sending church may be dense, but that’s because sending well is rich and nuanced. It’s not just about launching people out the door with a handshake and a budget line—it’s about embodying a deeply biblical posture of relationship, sacrifice, and mutuality. Let’s highlight some key observations that bring this definition to life:

“A local community of Christ-followers…”

This begins with identity. A sending church isn’t a program, committee, or special event—it’s the gathered people of God. Local churches are not peripheral players in God’s global mission. They are central. Sending is something the whole church owns together, not just the missions pastor or the most passionate few.

“who have made a covenant together…”

This phrase emphasizes commitment. Sending is not something a church does occasionally or by accident—it’s something they commit to as part of their identity. It flows from shared conviction, accountability, and unity in purpose. Healthy sending churches don’t just allow missions to happen; they promise to be part of it.

“to be prayerful, deliberate, and proactive…”

Sending well requires intentionality. Churches don’t drift into becoming healthy senders. It takes prayerful discernment, long-term planning, and proactive leadership. These words push back against passivity and call the church into thoughtful action.

“in developing, commissioning, and sending…”

These verbs outline a process. Sending doesn’t begin when someone is ready to get on a plane. It begins much earlier—with discipleship, training, mentoring, and affirmation. Commissioning publicly celebrates what God has done; sending launches them into the next season of ministry. These steps take time, clarity, and pastoral care.

“their own members…”

This is personal. The sending church isn’t outsourcing mission work to strangers—it’s sending its own. The implication is deep relational connection, spiritual responsibility, and long-term involvement. These are people you’ve baptized, discipled, and walked with. And when they go, your church goes with them.

“both locally and globally…”

Mission is not just a plane ticket away. A sending church has eyes on its neighborhood and on the nations. It is involved in cross-cultural disciple-making wherever God provides opportunity. The global call doesn’t replace local ministry—it expands it.

“often in partnership with other churches or agencies…”

This reminds us we’re not alone. Healthy sending churches recognize that collaboration often strengthens sustainability. Partnerships with mission agencies or other churches can provide expertise and infrastructure—but the sending church remains centrally involved.

“continuing to encourage, support, and advocate…”

Sending doesn’t stop at departure. It’s ongoing. It means writing letters, praying fervently, providing financial support, visiting on the field, offering counseling, and being the consistent voice of love and presence in hard places. It also means advocating on their behalf—helping others know, love, and support them too.

“while making disciples cross-culturally…”

This is the fruit and the aim. The goal is not just sending, but seeing lives transformed as the gospel crosses cultures. The sending church is aligned with Jesus’ commission to make disciples of all nations—not simply to send people somewhere.

“and upon their return.”

Reentry is one of the most overlooked pieces of the sending process. Returning missionaries often struggle to reconnect, find purpose, or process what they’ve experienced. A true sending church is also a receiving church—ready to welcome, listen, restore, and reengage returned workers in meaningful ways.

This is not a small vision. It’s a high calling. But it’s one worth striving for—and one that churches can grow into over time, with the right equipping and relationships.

Reflecting on Your Church's Sending Identity

Every church has a sending story—whether it's just beginning, long in the making, or in need of fresh vision. Now that you’ve seen a biblical example in Antioch and unpacked our definition of a sending church, take a moment to reflect. This isn’t about comparison or guilt. It’s about clarity, courage, and calling.

Here are some questions to help you discern where your church stands and where God may be leading you:

• Does this definition resonate with who your church is—or who you desire to become? What parts of it stir your heart? What feels unfamiliar or out of reach?

• Which aspects of the definition reflect current strengths in your church?Are there places where your church is already developing, sending, or sustaining people well?

• Which parts reveal gaps or growth areas? Are you intentional in preparing people before they go? Are you still connected with those you’ve sent? What happens when they return?

• Do you have a team or structure in place to pursue this vision intentionally?Or has sending remained the passion of just a few individuals?

• Is this a journey your church can take alone? What kind of support, resources, or relationships would help your church take the next step in becoming a healthier sending church?

Joining the Sending Church Movement

The story of Antioch reminds us that sending isn’t just a church’s activity—it’s a church’s identity. It’s what happens when the people of God, rooted in worship and listening to the Spirit, propel their own into God’s global purposes. That same calling is alive today. And your church has a unique part to play.

Whether your church is just beginning to explore what it means to send well, or you’ve been doing it for years and are ready to grow deeper, the journey ahead is both challenging and beautiful. You don’t have to figure it out alone.

At Upstream, we exist to walk alongside churches like yours. We offer resources that are both theological and practical—born out of real experience, shaped by Scripture, and designed to equip your leaders. But more than resources, we offer relationship: a community of churches and leaders who are learning together how to send better, support longer, and celebrate God's global work more fully.

If you’re ready to move from general passion to intentional sending, we’d love to help.
