How do we know the church has the authority to teach truth?

The authority of the church to teach truth comes directly from its divine commissioning in Scripture, particularly seen in 1 Timothy 3:15. God appointed the church as the steward of His truth, entrusting it with the responsibility to faithfully uphold and communicate His word. This divine authority is underscored by the calling of individuals within the church to serve as witnesses to that truth, ensuring that the teachings remain aligned with biblical doctrine. Thus, the church operates under the authority of Scripture and is compelled to reflect the character of Christ in its teachings and life.
