According to some systematic theologians it is. I made a thread about this a while back.
Came across this in Wayne Grudem’s Systematic Theology: 4. The Words of Scripture Are Self-Attesting. Thus, the words of Scripture are “self-attesting.” They cannot be “proved” to be God’s words by appeal to any higher authority. For if an appeal to some higher authority (say, historical accuracy or logical consistency) were used to prove that the Bible is God’s Word, then the Bible itself would not be our highest or absolute authority: it would be subordinate in authority to the thing to whi…
4. The Words of Scripture Are Self-Attesting. Thus, the words of Scripture are “self-attesting.” They cannot be “proved” to be God’s words by appeal to any higher authority. For if an appeal to some higher authority (say, historical accuracy or logical consistency) were used to prove that the Bible is God’s Word, then the Bible itself would not be our highest or absolute authority: it would be subordinate in authority to the thing to which we appealed to prove it to be God’s Word. If we ultimately appeal to human reason, or to logic, or to historical accuracy, or to scientific truth, as the authority by which Scripture is shown to be God’s words, then we have assumed the thing to which we appealed to be a higher authority than God’s words and one that is more true or more reliable.
5. Objection: This Is a Circular Argument.
Someone may object that to say Scripture proves itself to be God’s words is to use a circular argument: we believe that Scripture is God’s Word because it claims to be that. And we believe its claims because Scripture is God’s Word. And we believe that it is God’s Word because it claims to be that, and so forth.It should be admitted that this is a kind of circular argument. However, that does not make its use invalid, for all arguments for an absolute authority must ultimately appeal to that authority for proof: otherwise the authority would not be an absolute or highest authority. This problem is not unique to the Christian who is arguing for the authority of the Bible. Everyone either implicitly or explicitly uses some kind of circular argument when defending his or her ultimate authority for belief.
Although these circular arguments are not always made explicit and are sometimes hidden beneath lengthy discussions or are simply assumed without proof, arguments for an ultimate authority in their most basic form take on a similar circular appeal to that authority itself, as some of the following examples show:
- “My reason is my ultimate authority because it seems reasonable to me to make it so.”
- “Logical consistency is my ultimate authority because it is logical to make it so.”
- “The findings of human sensory experiences are the ultimate authority for discovering what is real and what is not, because our human senses have never discovered anything else: thus, human sense experience tells me that my principle is true.”
*“I know there can be no ultimate authority because I do not know of any such ultimate authority.”In all of these arguments for an ultimate standard of truth, an absolute authority for what to believe, there is an element of circularity involved.
I do think there is a valid point in there somewhere. God is the highest authority, We cannot appeal to some other authority to prove this as that would invalidate God as our highest authority. But at the same time, isn’t Grudem using reason when he says the Bible is self attesting and argues thusly? Are we not all slaves to reason by default? I’m not philosophically knowledgeable to get out of this pickle but it raises some interesting issues.
