The Bible does not refer to the Bible in the Bible.
It refers to Scripture, a rather nebulous and not fully defined term in the First Century. The Torah and the Prophets was defined. But the "Bible"? Not defined.
Nor does the Bible say "Bible alone".
You say it does.
The Bible is made by human hands.
You are insisting it is the totality of revelation.
It does not say so. (What about the miraculous healings at Lourdes?)
By denying the Church, which the Bible refers to a lot, but insisting the Bible is the Uber Authority, which it nowhere says, aren't you making a graven image out of the Bible itself, and worshipping it?
Earlier, you cited to Josephus, I believe.
Certainly the Jews of the Temple did not take your approach to the Scriptures. Nobody did, really, until Luther. And Luther didn't claim any divine revelation.
