I think its an excellent idea to have individual threads devoted to each point. But I wonder about the purpose of such a strong limit on the discussion. The reason we digging into this issue is because there are continued points of contention. How can we come to any resolution if we limit discussion to just two posts each? It seems like we will be left with the same situation with which we began - that is, unresolved differences.
To me, the solution would be to discuss each point (or question) listed in the outline until we come to agreement on either 1) the true Biblical teaching on the issue, or 2) the specific reason(s) for the difference(s). If we come to a solid agreement about 1) then we post a synopsis of that in an expanded outline that contains both questions and answers, and that will be continuously updated. If on the other hand we come to 2) then we start a thread to resolve those specific new "root issues" that have arisen.
My main point is that it seems like just "stating our different positions" will not ultimately resolve our differences. And our common purpose is to discover the true Biblical teaching on these issues, correct? So we should be able to state each point of total agreement, and then break down the points of disagreement until we find the remaining "root issue" that needs to be resolved.
