Around here, we’ve long talked about Israel’s Year of Jubilee as a paradigm for a healthy economy. José Humphreys and Adam Gustine, in their new, brief book Ecosystems of Jubilee, pull this idea, along with the related Old Testament concepts of Sabbath and gleaning, into three extended ethical reflections on the Bible’s vision for communal life. The book self-contentiously lands amid a broad, often cutthroat conversation about economic justice in the United States. But, following a few forebearers, Humphreys and Gustine avoid cheap narratives and lean into a nuanced idea of a collective, intertwined social life that may lead repair and health for all.
