The Gathering Center

In the last section of the book, Tickle argues that during each Re-Formation, about 60% will join the new order, 9-12% will vehemently oppose it, and about 30% will be left in between. That 60% she calls 'the gathering center.'

It seems, especially in light of the Protestant denominationalism and the Roman Catholic central authority, that this center is course correction for these two principles. How do you envision a gathering center that is neither so independent that it cannot commune nor so regimented that it cannot disagree? Is there another way?
