The document discusses the meaning of "church" based on passages from Acts and the Greek word "ekklesia". It explains that church refers to a gathering or assembly of believers in a community, not a building. The early church in Acts was devoted to learning from the apostles, fellowship, breaking bread together, and prayer. They shared possessions and met daily for teaching, meals, fellowship, and praise. The church is where believers gather in Jesus' name to encourage one another, remember Jesus through communion, and pray.
