What does Scripture say about adding to extra-biblical revelation?

The statement that Scripture warns against adding to the Bible is rooted in specific verses found in both the Old and New Testaments. For instance, in Revelation 22:18-19, there is a clear admonition against adding to or taking away from the words written in the book. This highlights the belief that the canon of Scripture is complete and that any additional revelations outside of it should be regarded with caution.

This understanding emphasizes the authority of Scripture as the final revelation of God's will for humanity. It suggests that while believers can gain insights from various sources, any teaching or revelation that contradicts or seeks to augment the established biblical text is not aligned with traditional Christian doctrine. Hence, the strong caution against introducing extra-biblical revelations underscores the need for discernment and adherence to Scriptural integrity.
