The question you are posing is highly misleading.
In every book of the Bible, God shows his authority through scriptures. So maybe you want to rephrase your question.
EDIT: Here are some passages you can read about the scriptures - Psalm 119:89, Joshua 23:6, Joshua 1:8, 2 Kings 22:11, Ezra 10:1-4, Nehemiah 13:1-3, Isaiah 40:8, 1 Thessalonians 2:13, Luke 16:17.

It's a pretty clear cut question about your protestant doctrine. Where does it teach bible only belief in the bible? This will be the 3rd or 4th time I rephrased it for you. You're just avoiding the question. Just answer it.

Read the edit of the previous comment but I will post it again: Here are some passages you can read about the scriptures - Psalm 119:89, Joshua 23:6, Joshua 1:8, 2 Kings 22:11, Ezra 10:1-4, Nehemiah 13:1-3, Isaiah 40:8, 1 Thessalonians 2:13, Luke 16:17.
Edit: Once again, in the KJV original version.
