The concept of a missionary, as understood in contemporary Christian discourse, is deeply rooted in the biblical narrative and the early church's practices. However, the Bible does not explicitly use the term "missionary" in the way we do today. Instead, the Bible presents a vivid picture of individuals who are called and sent by God to spread the Gospel, embodying the essence of what we now consider a missionary's role. To understand how the Bible defines a missionary, we must explore the lives and teachings of the apostles, the Great Commission, and the broader scriptural mandate for evangelism and discipleship.
The term "missionary" is derived from the Latin word "missio," meaning "to send." In the biblical context, this aligns closely with the Greek word "apostolos," from which we get the term "apostle," meaning "one who is sent." The apostles, particularly the twelve chosen by Jesus, are often seen as the prototypical missionaries. They were given a specific mandate to spread the teachings of Jesus and establish the early church. In Matthew 28:19-20, often referred to as the Great Commission, Jesus instructs His disciples, saying, "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you." This directive encapsulates the essence of missionary work: going forth, teaching, baptizing, and making disciples.
The Book of Acts provides a narrative of the early church and the missionary journeys of the apostles, particularly Paul, who is often regarded as the foremost missionary of the New Testament. Paul's life and ministry offer a comprehensive model of what it means to be a missionary. He traveled extensively, preaching the Gospel, establishing churches, and nurturing new believers. His letters to the churches, which form a significant portion of the New Testament, reflect his deep commitment to spreading the message of Christ and addressing the spiritual needs of diverse communities.
Paul's approach to missionary work was characterized by several key elements that continue to define missionary activity today. First, he was driven by a profound sense of calling and purpose. In Romans 1:1, Paul identifies himself as "a servant of Christ Jesus, called to be an apostle, set apart for the gospel of God." This sense of divine calling is fundamental to the missionary identity. Missionaries are those who feel compelled by God to share the Gospel, often crossing cultural and geographical boundaries to do so.
Second, Paul's missionary work was marked by adaptability and cultural sensitivity. In 1 Corinthians 9:22, he famously writes, "I have become all things to all people, that by all means I might save some." This adaptability is crucial for missionaries who must navigate different cultures and contexts while remaining faithful to the core message of the Gospel. Paul's ability to engage with diverse audiences, from Jewish synagogues to Gentile marketplaces, underscores the importance of cultural understanding in missionary work.
Third, Paul's ministry was characterized by perseverance and resilience in the face of opposition. Throughout Acts and his epistles, we see Paul enduring hardships, persecution, and imprisonment for the sake of the Gospel. In 2 Corinthians 11:23-28, he recounts the many trials he faced, yet he remained steadfast in his mission. This resilience is a hallmark of missionary work, as those who are sent often encounter challenges and resistance in their efforts to share the Gospel.
Beyond the example of Paul and the apostles, the Bible presents a broader theology of mission that encompasses the entire church. In 1 Peter 2:9, believers are described as "a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light." This passage highlights the collective missionary identity of the church, emphasizing that all Christians are called to bear witness to God's transformative work in their lives.
The Old Testament also provides a foundation for understanding the missionary mandate. God's covenant with Abraham in Genesis 12:1-3 includes the promise that "in you all the families of the earth shall be blessed." This indicates God's intention to use His people as a conduit of blessing and revelation to the nations. The prophetic literature, such as Isaiah 49:6, further underscores this calling: "I will make you as a light for the nations, that my salvation may reach to the end of the earth." These passages reveal that the missionary impulse is not a New Testament innovation but is woven throughout the biblical narrative.
In addition to scriptural foundations, Christian literature and theology have further developed the concept of missions. Influential works such as "The Mission of God" by Christopher J.H. Wright and "Let the Nations Be Glad!" by John Piper explore the biblical basis for missions and the church's role in God's redemptive plan for the world. These works highlight the theological conviction that mission is not merely an activity of the church but is central to its identity and purpose.
Furthermore, the role of the Holy Spirit is crucial in understanding the biblical definition of a missionary. In Acts 1:8, Jesus promises His disciples, "But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth." The empowerment of the Holy Spirit is essential for missionary work, enabling believers to proclaim the Gospel with boldness and effectiveness. The Spirit's guidance and presence are evident throughout the missionary journeys in Acts, affirming that mission is a Spirit-led endeavor.
In contemporary practice, the definition of a missionary has expanded to include not only those who travel to distant lands but also those who engage in local evangelism and service. The global nature of the church today means that mission fields exist in every community, and the call to be a missionary is not limited to a select few but is a shared responsibility of all believers. This understanding aligns with the New Testament vision of the church as a community of witnesses, empowered by the Spirit to make disciples of all nations.
In conclusion, while the Bible does not explicitly define the term "missionary" as we use it today, it provides a rich and compelling framework for understanding the role and identity of those who are sent to proclaim the Gospel. Through the example of the apostles, the teachings of Jesus, and the broader biblical narrative, we see that a missionary is one who is called and sent by God, empowered by the Holy Spirit, to share the message of Christ with all people. This calling is rooted in the Great Commission, the example of the early church, and the enduring mission of the church to be a light to the nations. As such, every believer is invited to participate in this mission, bearing witness to the transformative power of the Gospel in their own context and beyond.
