This is an excellent suggestion in my view and certainly in accordance with the aims of the site. I have some general suggestions.

1. Give some further thought to how the discussion should be structured. Is everyone happy with joeblow’s proposal? Does it need refining, correcting, developing?

2. Break the discussion down into separate topics in the forum, eg. along the lines of the questions that joeblow has listed. The current thread has become unwieldy. As a general rule, I would suggest that if contributors plan to push discussions in different directions, they should start a new topic, perhaps with a brief comment inserted into the original thread pointing to it.

3. Clarify what’s needed to keep this a ‘progressive’ (in the best sense of the word) discussion - by which I mean that it should not just rehearse all the old theological positions but should ask what is required by an emerging orthodoxy / theology.
