Jesus did something that was done on a daily basis: in a culture/society where sandals and dust and probably raw sewage was common, but well before modern daily showers, covered shoes, and clean sidewalks, foot-washing was common.
We want to go out into the city, not out of a sense of noblesse oblige (the "inferred responsibility of privileged people to act with generosity and nobility toward those less privileged,") but out of a loving, Christ-like, Jesus-following sense.
The day will end with a simple Taize-style worship service, with communion. As part of the service, we'll invite folks to light a votive candle and say a prayer of thanksgiving for those who serve, while praying that the desire to serve others continue to burn within us, year-round.
If this idea gains traction, in future years, I'd love to find ways we as a congregation can serve the city: take on some unwanted task in the city somewhere -- some nasty project no one wants to take on that 100 church folk could descend upon and make a real difference in one day.
But this year, I find myself looking forward to Maundy Thursday in ways I haven't for years. Because this year's Maundy Thursday service will be Maundy Thursday SERVICE. And that somehow feels more Jesus-like.
