Most past religious scholarship has drawn a dichotomy between urban and suburban churches and has compared religious observance and denominational membership by race, gender, ethnicity, and recently, around the emergence of a “knowledge” and “entrepreneurial” class forms of church practice. Diverging from previous models, Justified by Work,, based on author interviews with a wide spectrum of working-class Chicagoans, offers a comparative study of working-class religious practice and faith, across race and ethnic identity. Christian churches are represented by a Catholic Mexican congregation, an African American Baptist church, and a mixed eastern European church. Bruno examines as well how religious observance affects the life and attitudes of working-class Jews and Muslims in Chicago.
