This morning's lectionary includes the brilliant and important first 12 verses from Isaiah 58, beginning with the exhortation to "shout out, do not hold back" and ending with the wonderful vision that the seeker of justice shall be called "the restorer of streets to live in". How great is that: building a community that people can truly live in. In between verses 1 and 12 are practical admonitions to "let the oppressed go free" and "break every yoke" and "share your bread with the hungry" and "bring the homeless poor into your house". The prophet, staring directly at the religious and political elites, denounces their pious practices as empty and hypocritical gestures, and says that the most important fast is to "loose the bonds of injustice". All of which begs the question: is the key to building a just and fair society found in the volume of our rage? Does more shouting lead to more justice? Some advocates confuse their own self-righteous anger with a sense of justice. Yes, the prophet says that words are important, but so too are actions - actions that bring immediate comfort to the hungry, the homeless, the naked and the poor. Also, actions that tackle the fundamental injustices that generate poverty and racism and homophobia and misogyny and all the other ills of this world. The real work of advocates is to create communities that people can live in.
