One of the first things that struck me when I started attending a ministry with the poor and homeless in my town was the nature of performance in the service. (I'm tempted to write "lack of performance," but that's not quite right.) The ministry is dedicated to seeing and hearing those who are most often invisible and unheard, and every service sets aside time for anyone to "share": a story, poem, song, dance, prayer, whatever. People forget or change the words to the song they're singing, change key or sing off-tune, stop playing mid-song and start again, weep at their own story, drop things, etc.--and it is profoundly affecting. It made me wonder why the same thing in a conventional service would be distracting while here it is moving. But I think it's the lack of distance between the (imperfect) artifice of those performers and their real selves, hungry to be seen and heard, hungry to have their talents recognized and applauded. It's really beautiful.
