Oh how I wish this could be explained and convinced to biblical fundamentalists. As if accepting words at face value is not an interpretation?
Before we even read a word of Scripture we have an opinion as to what we will find. An Atheist will automatically dismiss the notion of God so the first sentence is virtually a closer. The bible is not unbiased, or pragmatic, or “fair”. It assumes a belief in God.
If God had to rely solely on the bible for His revelation He would be dismissing the vast majority of His created race. So on that basis if none other Sola Scriptura falls. Prima Scriptura assumes knowledge and acceptance that is also unreasonable. You cannot rely on what you neither know or believe.
