2 Corinthians 1:13-14
13. For we do not write you anything you cannot read or understand. And I hope that,
14. as you have understood us in part, you will come to understand fully that you can boast of us just as we will boast of you in the day of the Lord Jesus.
Does this translate into "The Bible alone?"
When examining Scripture passages which supposedly support the doctrine of "the Bible alone," two questions should be asked: Does the passage itself support the doctrine of "the Bible alone," and even more fundamentally, Who determined that this passage constituted Sacred Scripture, and by what authority did they determine this?
An ancient document purporting to be a "gospel" does not in itself constitute proof of its validity as Sacred Scripture.
