What is the Church and its Mission?

As a new believer in Christ, it's important to understand the core concepts of the Christian faith, including the role and purpose of the Church. The Church is not simply a physical building or an organization, but rather the spiritual body of all those who have placed their faith in Jesus Christ as their Lord and Savior.


The concept of the Church has its roots in the Old Testament, where God chose the Israelites, the 12 tribes of Israel, to be His people and to fulfill [through them] His promise of salvation for humankind. In the Old Testament, God established a covenant relationship with the Israelites, calling them to be a light to the nations and to bring the knowledge of the one true God to the world (Genesis 12:1-3, Exodus 19:5-6). However, the Israelites often fell short of this calling, and their obedience to God's law was overshadowed by their inability to perfectly fulfill it.


It is in this context that the New Testament Church emerges as the new people of God, built upon the foundation of the 12 apostles of Christ (Ephesians 2:19-20). The Church is now composed of all those who have put their faith in Jesus Christ, whether they are Jew or Gentile, slave or free (Galatians 3:28). As the apostle Paul writes in 1 Corinthians 12:12-14, "For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit."


The primary mission of the Church is to proclaim the gospel of Jesus Christ and to make disciples of all nations, as commanded by Christ Himself in the Great Commission. In Matthew 28:19-20, Jesus instructs His disciples, "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 command is not just for the original disciples, but for all believers throughout history.


It is important to note that while baptism and the observance of the Lord's Supper are central to the life of the Church, these practices do not in themselves confer salvation. Salvation is a gift of God's grace, received through faith in Jesus Christ alone (Ephesians 2:8-9). Baptism and the Lord's Supper are outward symbols of the believer's identification with Christ and their participation in the life of the Church, but they do not earn or merit salvation.


As believers, we are called to be witnesses to the truth of God's Word, sharing the good news of salvation with those who have not yet placed their faith in Christ. In Acts 1:8, Jesus tells 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." This calling to be witnesses extends to all who have been saved by grace through faith in Christ.


The Church is also called to be a light to the world, demonstrating the transformative power of the gospel in the lives of believers. In Matthew 5:14-16, Jesus instructs His disciples, "You are the light of the world. A city set on a hill cannot be hidden. Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven." The Church is to be a beacon of hope, love, and righteousness in a dark and broken world.


Furthermore, the Church is called to be a community of believers who care for one another and support one another in their spiritual growth. In Acts 2:42-47, we see the early Church devoted to the apostles' teaching, fellowship, the breaking of bread, and prayer. They shared their possessions with one another, cared for the poor and needy, and praised God together. This model of community and mutual care is an essential aspect of the Church's mission.


Ultimately, the Church has a glorious destiny awaiting it. In Ephesians 5:25-27, the apostle Paul writes, "Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish." The Church, as the bride of Christ, will one day be presented to Him in all its glory, purified and perfected by the work of the Holy Spirit.


In summary, the Church is the spiritual body of all believers, united in Christ and called to proclaim the gospel, make disciples, bear witness to the truth of God's Word, be a light to the world, and build a community of mutual care and support. As a new believer, it is essential to understand the purpose and mission of the Church, so that you may be an active and faithful member, contributing to the growth of the body of Christ and the fulfillment of God's promise of salvation for all people. And as we faithfully serve the Lord, we can look forward to the day when the Church will be presented to Christ in all its splendor, as the beloved bride for whom He gave His life.
