Oops. I think I jumped ahead too quickly there for you on the Elertian reference, Matt J. What is being discussed is saving faith. Saving faith is not something you do, is not subjective, is not the you that is you doing anything. It is quite the opposite, In the words of the theologians, its a mathematicum punctum, a mathematical point. And the mathematical point, for Luther, is that the ash left of you when you are along with all humanity dead in your trespasses and sins is covered objectively by the cross of Christ. The doctrine of the Word is that which reveals the innermost thoughts and discernments of the heart (Hebrews 4) and thereby as the living and active two-edged sword cuts you to the bone, revealing the spot in you and all humanity that is addressed by and covered by the Gospel - the availiing death and resurrection of Christ. This is the theologians' way of expressing what historically transpired at the hearing of Peter's words in Acts 2.
There is, of course, a theological category of "appropriating faith," that which clings to the promise delivered. But saving faith cannot begin with or be anchored in human effort, or you're left with the Baptist "I believe that I believe that I believe that I believe" deal where what you have faith in is your faith, which is a tautology and not a useful one.
I think what you're outlining is useful in terms of the "statements;" the documents will be fluid, and normally proceed on the basis of "here's what we all hold to be true, here's where the areas of difficulty are, and here's what's happened in uncovering those;" and so forth unto conclusion.
The Synod's Task Force on Harmony has been working for a number of years and their insights as to the areas for theological study will be part and parcel of the Koinonia Project.
