What does the Bible say about the church's authority?

According to 1 Timothy 3:14-15, the church is described as the pillar and foundation of truth. This means that the church is entrusted with the truth and should solely rely on Scripture for guidance rather than on human traditions or man-made doctrines. The church does not define what truth is; instead, it has been given the truth and is responsible for proclaiming it faithfully. Therefore, the validity of any church can be measured by its adherence to the Scriptures, which we believe to be a reliable and sole authority in all matters of faith and practice.
