Looking for a book or resource that talks about the revolutionary/radical nature of the early Christian Church

Hi Everyone,

This summer, I'm looking for a book that shows that the early Church was radical/revolutionary in carrying out the social justice teachings of Jesus.  I'd like to show the students that the early Church was persecuted, in part, because of their different lifestyle that incorporated resistance to the Roman concept of justice.  Thanks and Happy Summer to All!  John Powell
