Social postmodernism and systematic theology can be considered the new pair in some of the most creative discussions on the future of theological method on a global scale. Both in the academy and in the public square, as well as in the manifold local and pastoral moments of ministry and community social activism, the social, the postmodern, and the theological intermingle in engaging and border-crossing ways. The Community of the Weak presents a new kind of jazzy fundamental theology with a postmodern touch, using jazz as a metaphor, writing ethnographically messy texts out of the personal windows of lived experiences, combining fragments of autobiography with theological reconstruction. A comparative perspective on North American and European developments in contemporary systematic theology serves as a hermeneutical horizon to juxtapose two continents in their very different contexts. The author proposes a systematic and fundamental theology that is more jazzy, global, and narrative, deeply embedded in pastoral ministry to tell its postmodern story.
