why is it important to have an official list of biblical books

It is important to have an official list of biblical books—known as the canon—because it provides a definitive, authoritative guide to the Scriptures recognized by the faith community. This official list ensures that the books included are those truly inspired by God and authoritative for faith and life, distinguishing them from other writings that may be devotional or historical but are not divinely authoritative. The canon helps maintain theological consistency and unity within the church by confirming which texts should be used for teaching, doctrine, and worship. The term canon comes from a Hebrew word meaning "reed" or measuring rod, symbolizing the idea of an official standard or "measuring stick" for the inspired biblical texts. Without such a list, believers would struggle to know which writings truly convey God's message, especially given that many writings with spiritual claims have existed (and still exist). The canon arose not by human decision alone but through the recognition of the inherent divine authority of certain books, confirmed by their apostolic authorship or close association and their consistent theological truth. Having an official canon also helped early believers and the scattered Jewish people remain united around a common, authoritative set of Scriptures. Thus, an official list or canon of biblical books safeguards the spiritual integrity of the Bible, assures believers that they are reading God's true word, and fosters unity and order in Christian faith and practice.
