Tri-generational?
Interesting article at Theooze called The tri-generational model.

In it Jeff Hughes suggests:
" I believe that a true postmodern church is a multigenerational community composed of people of all ages who desire to worship God in authentic ways."

The article explores what can be done altogether, and what can be done in generationaly or culturally specific spaces, yet with a desire to stay as part of an inherited church rather than go off and do something totally seperate.
Worth considering!
