A po-mo is a "post-modern".
Emergent Church services (at least the one I attended in Calgary) feature coffee-shop style seating, coloured lights, candles, locally created music and visual arts, "Eucharist" at the end of every service (serve yourself) and interactive sermons. It is really an honest attempt to "fix" the modern church.
What I most appreciated was the attempt at creating community; we were encouraged to turn to each other for support, not only attending Bible study together but also hanging out, going to movies, etc. I know it sounds forced (why would you need to encourage community?) but a lot of people who go to church together never bother with each other outside of that place.
When I discovered Orthodoxy, suddenly the need to fix the Church evaporated since it was never broken, and I hope that current po-mos will discover this amazing secret too!
