Book excerpt: What has theology to do with economics? They are both sciences of human action, but have traditionally been treated as very separate disciplines. Divine Economy is the first book to address the need for an active dialogue between the two. D. Stephen Long traces three strategies which have been used to bring theology to bear on economic questions: the dominant twentieth-century tradition, of Weber's fact-value distinction; an emergent tradition based on Marxist social analysis; and a residual tradition that draws on an ancient understanding of a functional economy. He concludes that the latter approach shows the greatest promise because it refuses to subordinate theological knowledge to autonomous social-scientific research. Divine Economy will be welcomed by those with an interest in how theology can inform economic debate.
