. Didn't you ever hear the phrase "We stand on the shoulders of giants?" Whose shoulders do you think this refers to?
Sure, the servants that God raised up such as the Brethren, Zinzendorf, Martin Luther.
2. When the Ethiopian eunuch said, "How can I understand unless someone explains it to me?", don't you think he was looking for an expositor to help him?
Sure. like Philip. Philip was not "Christian scholar".
3. Remember where Proverbs says (3x) "In a multitude of counselors there is safety."
Right. It does not say in the multitude of scholars.
4. Where do you think the "interpreted word" comes from? Christian scholars, no? Or is only one 'oracle' capable of doing so?
From a variety of believers and servants of God, not just scholars.
5. Psalm 45: "My tongue is like the pen of ready writer". We all can be Christian scholars; all of us. We can all be ready to expound on scriptures, and make a defense of the faith, should any enquire. The voice of the flock is the voice of the flock, not just one person speaking "ex cathedra".
I don't think it is accurate to say we can all be Christian scholars. What you mean is that we can all expound the scriptures and each can provide a revelation as the Holy Spirit inspires us. I Corinthians 14 says "each one has..". If this is what you mean then I agree with you.
6. Remember the "sound of many waters"?
The sound of Muddy Waters? Just checking. 
Seriously, if you mean by many waters all the believers sharing what the Lord has shown them and what they experienced of Christ then I agree with you in principle. But then, you are using a different working definition of christian scholars than Ohio used. He meant a class of intellectual Christians, what we call scholars in the traditional sense of the word, who validate minister's credentials. I disagree with him on that because it suggests academia is the qualification for the validation and it also usurps the authority of the Holy Spirit Who alone is responsible for the special commissions in the church.
