Since 1999, Rev. Billy and the Church of Earthalujah! have been performing creative, theatrical interventions against consumerism, often invading stores and malls to preach the gospel of reducing our consumer imprint. They call themselves a "post-religious" church, made up of performance artists, urban activists and anti-consumerist gospel shouters.

Rev. Billy was at Occupy Wall Street for a few days this week, and shared his thoughts about what he saw going on in Liberty Square.
