Biblical-Theological Economics

Kathryn Tanner suggests that:

... the whole Christian story is a vision of economy, a vision of a kind of system for the production and circulation of goods, beginning with God and extending to the world, from creation through redemption..... Christianity is every bit as much about economic issues as an account of the way prices are determined by marginal utilities. The Christian story, after all, is a story about God as the highest good, a God constituted by exchange among the persons of the Trinity, a God who aims, in creating and saving the world, to distribute to it the good of God'’s own life to the greatest degree possible.”
(Tanner, Kathryn, Economy of Grace (Minneapolis, Augsburg Fortress, 2005), page xi)

Even if we don't go along with Tanner's program (for a radical economy of grace and non-competitiveness), presumably there could be value in expressing the gospel in economic categories, such as profit and loss (c.f. Matthew 16:26) and cost (c.f. Luke 14:28). Cash conscious consumers can be called to invest in true treasure (Matthew 6:19-21).
