Hillsong's style of Pentecostalism relies on a deep engagement with consumer capitalism, as well as celebrity, youth, and digital cultures. In Cool Christianity, Cristina Rocha tells the story of how Hillsong's "Cool Christianity" aesthetic allowed it to make inroads among the Brazilian middle classes, who adopted Hillsong's brand of Christianity as a way of becoming cosmopolitan and establishing class boundaries. Rocha draws on the theoretical frameworks of material religion and lived religion to show how religion can be made globally relevant to young people through cool aesthetics, affect, and engagement with consumer culture--from fashion to music to branding--in the digital age.
