I will totally concede anything you say about new testament translation. I simply do not know much about it. But your intense preoccupation with having to have a noun in order to do a verb is a prime example of how we all tend to way over emphasize our own professional discipline. Surgeons view everything as requiring surgery, pharmacists say "there's medicine for that", leftists view everything as oppression and I guess Philologists view everything in terms of the misuse of nouns and verbs. I don't buy your premise that all the problems of the church would go away if we simply had a proper understanding of grammar.
You used an example of faith and believing. You actually make it too simple. How is faith a gift? Can a noun which when exercised is a verb be given? Is it given? Or is the human will changed so that now a person will believe. Is faith in a simple fact like the apple is red the same in my mind as faith that will save me from eternal damnation? Is faith involved in believing something the same as "the faith". Is obedience or the intention of future obedience part of saving faith? Is faith the same as saving faith. Is faith in James the same as faith in Ephesians? Why does Jonathan Edwards in his chapter on faith have about 80 paragraphs of explanation? These are examples of why important things like this cannot be reduced to nouns and verbs. That doesn't even scratch the surface.
This thread, which I didn't start, is about Owen's work "The Death of Death in the Death of Christ". I've been through it once and will not try it again. But once again, it cannot be reduced to issues of grammar. Who was Owen writing this to. What were his opponents views and what were they trying to do in the church? Was politics involved? To what extent was he under pressure - in other words what would happen to him if he lost? And then there is the theology itself.
The other reason I don't buy the theory that all the problems of the church can be resolved by better linguistic understanding is that most of the problems of the church involve deliberate apostacy and going against very obvious imperatives in scripture - not subtle theological differences.
Now at first I just blew you off as a crank. But not only are you interesting to talk to but apparently you are teaching somewhere and I have come to respect what goes on at that level, especially if a seminary is involved. It will make a difference, someday. And eventually we will start seeing some form of this influence at the local church level. I'm just trying to figure out what to think of it.
