> religious people

Seems to me that the focus should be on institutions as power centers, rather than beliefs or loosely defined "religious people".

Illich himself also noted how institutionalization of an initially revolutionary idea reverses its meaning, switching, say, liberation into oppression.

Power grabbers will always attempt power grabs, and will eventually distort an initial good idea. They will pretend to Embrace it, then attempt to Extend it with their own input, to finally Extinguish the original idea.

My Shift key seems to be Jittery, apologies :)
