Christian Anarchism [PDF ebook] 
A Political Commentary on the Gospel (Abridged Edition)

Christian anarchism has been around for at least as long as "secular" anarchism. Leo Tolstoy is its most famous proponent, but there are many others, such as Jacques Ellul, Vernard Eller, Dave Andrews or the people associated with the Catholic Worker movement. They offer a compelling critique of the state, the church and the economy based on the New Testament.
