Len has this to say on the postmodern theology blog:

My point is incarnation.. a physical, historical and fleshly manifestation of the truth. Lacking this we only have a modern propositional apologetic and reasonable sounding excuses about truth and witness. The church must be an embodied presence, and faith is participation in truth embodied in a faithful community.

So, I am not arguing that we abandon our multiple or electronic communities. I am arguing for a center of embodied presence. If we fail in that one, the others wont' be worth much.
