Alexandra, we agree.  I've often suggested that major change in "church" is needed. Here's one way to see this. 

I find it MUCH easier to believe that the collective church, being not just the clergy/bishops, but the laity, the doubtful, perhaps even the falling away, TOGETHER and COLLCTIVELY might be able to make a claim as to a humble grasp of truth as we can understand it at that point in time.

That statement carries two key elements.The first is that this can ONLY work if we're all in this together. It doesn't require 100% agreement, but will require a strong consensus, based on a constant and ONGOING dialog thru the church, at all levels. It requires humility, not just with each other, but with the understanding that we are all creatures, evolving in many ways including our understanding of the creation around us. That humility MUST admit that our understanding HAS to change. The power should cone not from a certainty that we're right, but that we're trying as hard as we can...
