The church is all people who belong to Christ.

"So guard yourselves and God’s people. Feed and shepherd God’s flock—his church, purchased with his own blood—over which the Holy Spirit has appointed you as leaders."
-Acts 20:28 NLT

"Just as our bodies have many parts and each part has a special function, so it is with Christ’s body. We are many parts of one body, and we all belong to each other."
-Romans 12:4-5 NLT
