I don't really care.
After giving it some more thought, I came to the conclusion that this could be a good thing. Not at all because of preservation of the church, but because women are now included in the administrative functions of an organization that wields state power and brings the community together (looking at it from the perspective of an American; I'm not sure how much cultural influence the Church of England has in the UK). Churches have taken several community functions that aren't necessarily religious in nature (congregating, having a speaker address an audience on a regular basis, helping the needy, etc.) and tried their damndest to mark it all with the indelible territorial scent of religion. While I don't feel any particular need to sit in a pew every Sunday, I can understand cultural, non-religious reasons why people would want to do that and it's why I'm not against the "atheist megachurch" as a concept.
It would be nice if the religious organization itself fell to the wayside, but I see the cultural significance of including women in the day-to-day decision making of an organization that allegedly holds a community together.
