church structure

Last week I posted a diagram from small ritual of egg or omlette church.

This week, Dave Wainscott of Holy Heteroclite posts this diagram of church structure. He asks the question: what stops the bottom structure from morphing into the top structure?



I wonder why that's the question?
If the 2nd law of thermodynamics applies to institutions, then shouldn't both degenerate into a more disconnected blob?
Do we sometimes pay too much attention to structures... at the expense of living the gospel?
