Book excerpt: What constitutes the good life and authentic Christian leadership in a high-speed technological society geared to perpetual economic growth? In a world of rapid change and heightened risks, how do we move beyond the tyranny of emergency and polarization toward a politics of engagement and time oriented to the long-term common good? Taking up key themes in the social teaching of Popes Benedict XVI and Francis, Sustainable Abundance for All argues that life in a risky, runaway world requires new forms of Christian praxis that are both forward-looking and rooted in tradition. Among the issues addressed are pathways toward sustainable development in the Anthropocene, automation and the transition to post-jobs society, the proactionary-precautionary debate over new technologies, and the dangers of becoming "people of the device." Sustainable Abundance for All lays the groundwork for new kinds of Christian social action and prophetic witness in the twenty-first century.
