The paper starts by giving a historical and philosophical explanation for the current separation between theology and economics. It is then argued that postmodern culture offers the church and theology an opportunity to get reinvolved in the world of business, and especially in Business Ethics. Before opportunities for involvement is discussed, the question on the unique nature of Christians ethics is posed. The notion of Christian ethics as essentially an understanding of reality is proposed and defended against rival interpretations of (...) Christians ethics. Finally the role that the church and theology can play in developing business morality on the marco-, meso-, and micro-economic levels are discussed. (shrink)
