The building in which a group of believers gathers
The church's role in the Father's plan to save us:
The church consists of Christ's disciples, whom the Holy Spirit has called together and sustains in faith. The church, Christ's disciples, also serve as Christ's witnesses to proclaim his name in all the world. And the church as a gathering of believers serves as the place where the Word of God is preached and faith is sustained, according to the Father's plan.
