The Bible explains “members” differently than secular culture. In 1 Corinthians 12:27–28: Paul says, “Now you are the body of Christ, and individual members of it. And God has placed these in the church.”
With church membership, everyone has a role or function. Some are eyes; others are ears. Some are feet; still, others are hands. That is why the Apostle Paul concludes: “For as the body is one and has many parts, and all the parts of that body, though many, are one body—so also is Christ” (1 Corinthians 12:12).
All Christians are called to be one in Christ and to seek opportunities for common witness and service.
