No. It was a "marker" as to which Protestant mindset you follow. The authority of the scriptures, indeed the decision which writings constitute the canon, is a mater of man's beliefs, first and foremost; in other words, based on human authority. As such, they have no intrinsic seal of authenticity other than what men/women in authority make of it (always claiming "higher power").
Thus, the Muslims will tell you that their scripture s the true Bible, just as the Jews will claim theirs, and Christians theirs (and there is more than one set of canons among Christians as we all know).
So, don't spout some God-given authority of the scriptures unless you can produce a seal of authenticity, a doubtless warranty that it is authored and even dictated [sic] by God, instead of being arrogated by the self-appointed "mouthpieces of God."
When God condescended to reveal himself to the Patriarchs, Prophets, and Apostles he did so in a way that those who received the revelation could comprehend according to the categories available to them as they knew the world
I very much agree with the latter part of that statement, but not with the first. God condescended Himself to become Man. Being a column of fire or a burning bush is hardly condescension. There is nothing humble about the OT God.
Sometimes those revelations were not completely clear to the author themselves but to be revealed over time
I agree that Patriarchs, Prophets and Apostles were not privy to a complete revelation. I doubt that they ever were. In everything they write, there is a string "bats are birds" element of human limitation.
I trust what Scripture says of itself, that it is divine, just like you trust atheistic scholars or the Greek Church. You believe the presuppositions of atheists and mystics. I believe the presupposition of God himself. When I read Scripture I see the face of God and when you read Scripture you see backward fools. Because God speaks in the text he also gives assurance to the faithful to the truth of the text. You, unfortunately, have no trancendent assurance in your finite authorities.
But let me be the first to acknowledge that some here do make Scripture merely a formal authority and the material authority lies in their spirituality. We Reformed folks reject this dichotomy. We stand in a unique position where on the one hand we call the Greeks and Romanists to give up their notions of an ontological Church and its notion of corporate revelation and on the other hand we call out to Evangelicals to reject their individualistic, subjectivistic spirituality that believes parroting the Bible is the same as knowing God and rejecting the corporate creeds and confessions they forget that man's heart is a perpetual forge of idols that needs to be checked by the corporate Church. Reformationals are consciously Trinitarian (not the subordianist type of the Greeks) in knowing God both in the one (Church) and the many (subjectively). Word and Spirit work together with the divinity of Scripture assured through the regenerated conscience always in connection to the Church.
God condescended Himself to become Man. Being a column of fire or a burning bush is hardly condescension.
Revealing himself to the puny categories of the human mind is condescending to the almighty.
