What does the Bible say about the authority of the local church?

The local church is not just a gathering of believers; it is an institution ordained by Christ to fulfill His great commission. In Matthew 28:18-20, Jesus explicitly bestows authority upon His disciples to make disciples, baptize, and teach all His commands. This implies that the work of the gospel is confined within a structured ecclesiastical framework, where the local church acts as God's instrument on earth. It is through this gathered community that the fullness of God's word and sacraments are administered, allowing for the spiritual growth of individuals and the edification of the body of Christ. Churches are to ensure that their teachings align with the doctrines delivered once for all to the saints, paving the way for faithful service and worship.
