Christian ethics applied to economics and business has a long tradition. This dates back at least to the thirteenth century, with noteworthy developments in the four following centuries and again in the last century. Christian faith and reason intertwine to bring about principles, criteria, and guidelines for action and a set of virtues with relevance for economic activity. Christian spirituality, with 2000 years of history, has been embedded in Christianity from its beginning, but the application to modern business activity is (...) relatively recent. This article introduces a special issue which, we hope, will make its own small contribution to the developments of both Christian ethics and spirituality in the leading business organizations. After a short historical overview and a consideration of the current situation of Christian ethics and spirituality in business, we introduce the papers selected for this issue. (shrink)
