A very noble proposal, Jeff.

Unfortunately, history shows that there are only two results that have occurred in that pursuit:

Synods meeting soon after the "apostolic age," attempting to unify established doctrinal differences of the various and divergent denominations, existing at the time, ending in utter failure.

or Unitarian Universalism - " Unitarian Universalism is a progressive libertarian religious movement that is characterized by a 'free and responsible search for truth and meaning.' "

That begs the question, "Is doctrine important, or doesn't it matter what you believe as long as you believe?"
