Book excerpt: God does not appear in the modern market. For most economists this is as it should be. It is in no way necessary, according to modern economic theory, to consider God when thinking about economy. Indeed, the absence of God in economic matters is viewed as necessary to the great advances in modern economy. The difficulty with modern market economies, however, is that human livelihood is also left out of the theory and practice of the market economy. ?"I propose to bring the church's teaching about God, the doctrine of the Trinity, to bear on the masked connections between God and economy. I will treat the Trinity as the way of understanding what the Bible calls the 'economy of God.'?
