Where the English word came from
Church is an English word, not a word found in the original Greek New Testament. It developed from Old English cirice, related to the Scottish word kirk, and ultimately to the Greek word kyriakon. That Greek term means something belonging to the Lord, from kyrios, meaning “Lord”.
Over time, the word came to describe both a Christian gathering and the place where Christians gathered. That is why people may say, “I’m going to church,” meaning a service or a building. But the Bible’s main emphasis falls elsewhere.
The New Testament word is ekklesia
When the KJV says “church”, it usually translates the Greek word ekklesia. It means an assembly, gathering, or called-together body of people. The word could even describe a public crowd or civic meeting, as it does in the uproar at Ephesus, where the KJV uses the word “assembly” for the same Greek term (Acts 19:32).
For Christians, ekklesia came to mean the people gathered in response to Jesus. When Jesus spoke of building his church, he was not mainly speaking about constructing a religious building. He was speaking about forming a people who belong to him (Matthew 16:18).
And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
A church is people before it is a place
The earliest believers often met in homes. They learned from the apostles, shared meals, prayed, and cared for one another in Jerusalem (Acts 2:42). Paul could also greet a church meeting in the home of Aquila and Priscilla (Romans 16:5). A congregation did not need a dedicated building in order to be a real church.
That does not make church buildings unhelpful. They can be wonderful places for worship, hospitality, teaching, and service. Still, a building is not the church in the deepest biblical sense. The church is the community of people joined to Christ.
Now ye are the body of Christ, and members in particular.
Local churches and the wider church
The New Testament uses church in more than one way. It can mean a particular local congregation, such as believers meeting in one town or house. It can also point to all who belong to Christ, united across places and generations. Paul describes believers as members of God’s household, being built together as a dwelling place for God (Ephesians 2:19-22).
So when you hear the word church, think first of people, not bricks. It is Christ’s gathered family, learning to worship him and love one another. Reading the passages where the word appears is a good way to see how rich that simple word becomes.
