The Church

Jesus Christ was the first to use the word 'Church' in the New Testament. Today, many think of churches as buildings. What is the Church actually, according to the Bible? The biblical root word for 'church' is the Greek ekklesia. What does that mean? How does the Bible describe the original churches? How does one become part of Jesus Christ’s Church? Are there any specific things that need to be done?

Jesus selects the Church

Theme Text“And those he predestined, he also called; those he called, he also justified; those he justified, he also glorified.” (Romans 8:30 NIV)

The Church is a people, not only a place

When people say “church,” they often mean a building. Buildings matter because they give communities a place to gather for worship, prayer, grief, joy, teaching, meals, and mutual care. Still, in the Bible, the Church is first a people: a living community shaped by Jesus Christ’s call.

That call is not about earning rank, proving worth, or climbing a social ladder. Romans 8:30 places the focus on God’s action from start to finish: called, justified, glorified. The Church begins here, with grace received, not status achieved.

Ekklesia: a gathered community

The New Testament word often translated “church” is the Greek ekklesia. In common Greek usage it referred to an “assembly” or “gathered group.”1 Because the word can be traced to “calling,” some people say it means “the called-out ones,” but that can be misleading if it replaces the ordinary, first-century sense of a real, visible gathering.2

Jesus speaks of this community as a people who belong to him. He tells his disciples:

“If you belonged to the world, it would love you as its own. As it is, you do not belong to the world, but I have chosen you out of the world. That is why the world hates you.” (John 15:19 NIV)

This does not mean withdrawing from neighbors or despising society. It means being re-formed into a different kind of belonging, where love is not a reward for the impressive, and where honor is not reserved for the powerful.

What the earliest churches looked like

The earliest churches were local gatherings of believers, sometimes small, sometimes growing, meeting wherever they could. The New Testament often identifies these communities by place and relationships, for example, believers meeting in homes.3

  • As the disciples grew in number, they gathered for worship, fellowship, and teaching. These gatherings were called “churches” regardless of size.
  • They were often described by location and community ties, for example, the church in Jerusalem, the church in Philippi, the church in Rome, and the church that met in the house of Priscilla and Aquila.
  • Scripture describes Christ as the head of the Church (Ephesians 1:22–23), and it speaks of the Church as Christ’s “body,” a community of many members held together by one Spirit:

“Just as a body, though one, has many parts, but all its many parts form one body, so it is with Christ. For we were all baptized by one Spirit so as to form one body, whether Jews or Gentiles, slave or free, and we were all given the one Spirit to drink.” (1 Corinthians 12:12–13 NIV)

This “body” picture quietly resists the habit of sorting people into superior and inferior categories. In Christ, difference does not disappear, but it is no longer used as a reason to exclude, shame, or dominate.

How people entered the Church in Acts

On the day of Pentecost, Peter announced the good news about Jesus to the crowd and gave a clear invitation:

“Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit. For the promise is for you and your children and for all who are far off, as many as the Lord our God will call to Himself.” (Acts 2:38–39 NASB)

Many responded, and the community grew in the days that followed:

“And the Lord added to the church daily such as should be saved.” (Acts 2:47 KJV)

These steps still describe the basic shape of entering the Church today:

  1. They repented – a change of mind, turning toward Christ.
  2. They believed in Jesus, placing their faith in him as the God-sent Christ, the Savior of the world.
  3. They were baptized in the name of Christ, dedicating their lives to him and to the gospel of the Kingdom.

And as promised, they received the Holy Spirit, not as a badge of superiority, but as God’s gift for life together, love, courage, and faithful witness.

Why churches still matter today

In many places, churches are among the most dependable sources of comfort and steady care. Congregational relationships can become real social support, and clergy often provide practical help through counseling, encouragement, and guidance during grief or hardship.4

Churches also serve their wider communities in concrete ways. Research on U.S. congregations, for example, reports that many provide programs such as food pantries, emergency clothing, shelters, counseling, tutoring, and other forms of support that reach beyond their own members.5

In times of crisis, faith-based groups often show up quickly with immediate relief like food, water, clothing, shelter, and spiritual care, and they may also participate in longer-term rebuilding and recovery.6

None of this means churches are perfect. It means churches can be places where God’s calling becomes visible through worship and service, and where people learn to treat one another not as rivals competing for recognition, but as neighbors entrusted to one another’s care.
