What does the scripture say about the role of the church?

The church plays a crucial role in God's redemptive plan by being the vessel through which the gospel is proclaimed. As seen in Peter's sermon during Pentecost, the church is called to declare the works of Christ and to reinforce the truth of scripture. The function of gathering believers, preaching the Word, and administering sacraments is designed to equip the saints for ministry and nurture their growth in grace. This is why the church, as the body of Christ, must adhere strictly to scriptural tenets, ensuring that its foundation remains in God's Word. Failure to do this renders the church ineffective in her mission.
