In this article, we will investigate the relationship between economics and Christian ethics in three different ways. The first part will explore three new fields in economics. More specifically, part 1 explains the significance of religion and the economics of religion. Further, it will relate the economics of religion to economics as a whole. The next section of part 1 will involve a survey of the new field of the economics of happiness. Finally, the last section of part 1 will review religious, economic, and political liberty from the standpoint of New Institutional Economics. Part 2 of this article will explore the empirical work that has been done to explore these relationships. The last part of this paper will draw some conclusions about how economic, political, and religious liberties are related.
