Thought provoking. To paraphrase to ensure I understand correctly, the meaning is the significance of the rule being another result of debate or decree, either of which prod the community to face in the same direction. Whether or not it appears to make sense is somewhat secondary to preserving and strengthening the coherence of the community (c.f. Papal decree and infallibility)?

As an atheist of Protestant heritage I've wondered on the secret sauce of religion that brings the obviously stronger sense of community, as it appears to run deeper than faith, and whether there are ways to achieve that in a secular context. Perhaps particularly difficult in an era when individual choice and consumerism is promoted as paramount. :)
