Another problem with the canon argument is that many (if not most) Catholics today seem to believe in the “material sufficiency” view of the Bible (See Part 6 of this series). This view states that the Bible has all the necessary “material” in it. If that’s true, then the canon (which is not in there) must not NEED to be in the Bible. So, if the “material sufficiency” view is correct, this canon argument against Sola Scriptura cannot be true. No one can hold to the canon argument and to the “material sufficiency” view at the same time.
So, the fact that the canon is not specifically listed within the pages of Scripture does nothing to affect the Bible’s sufficiency as our Ultimate Rule of Faith.
