I have posted my message for Oct 21 in a blog.  In it the overriding theme is truning the world upside down in many different ways.  In particular I use the stories from Mark 10:17-52 as examples.  Elsewhere in the service I will briefly refer to the tendency of revoltuionary movements to become status quo movements: PRE in Mexico; Masons which started as the only safe plalce to discuss politics and religion to a place where discussion of religion and politics is discouraged, and the church.
