This is a critical moment. Jesus is doing more than making the disciples' feet clean, he is preparing them for the days to come. Peter, true to his nature, asks for a full bath. Jesus uses this opportunity to unveil the full symbolism of the moment. They are not unclean, except for Judas. The doubter, the loudmouth, the former tax collector -- all of them -- are equipped and ready. The one thing they are missing? Learning to serve one another, learning to serve the church that is to come.
