Well, aren't you just special...
But I will say that the kjv is certainly not corrupt...your professor probably has a bias against it because of its take on holiness...he probably wants to have his cake and eat it, too....believing in a gospel that will save him from hell without saving him from sin first...for that he probably does not want to be saved from sin....he probably loves his sinful lifestyle and therefore does not want to give it up...which would account for a bias against the kjv...since the teaching of the kjv is that you cannot have your cake and eat it, too!
I will say that I read English quite well...
And that I believe that God, in His sovereignty, Omnipotence, and love is both able and willing to preserve His unadulterated message in Bibles that we can read in our own language.
So, I'm afraid that you put all of that effort into learning Greek for nothing...because you will get no less of the unadulterated message of the word of God by reading it in the English than if you read it in the Greek.
In fact, the "educated" scribes and Pharisees rejected Jesus while the common people heard Him gladly.
And thus the "educated" Greek and Hebrews scholars might be more inclined to reject Jesus and what He says to us than those who read His unadulterated word in the English language (the common people).
