How do we know the Church's authority is true?

The authority of the Church hinges on her appointment by Christ, who commands that she govern the affairs of His household. Ephesians 2:20 states that the Church is built on the foundation of the apostles and prophets, with Christ as the cornerstone, establishing her as the rightful authority. This governance includes selecting leaders, maintaining order, and administering discipline. Additionally, the Church's teachings and practices must align with Scripture, as emphasized in 1 Timothy 5:19, which outlines the process for addressing accusations against elders, ensuring due diligence in her authority.
