The politics of the 20th century are primarily determined by political pragmatism. Religious and moral considerations regularly play a secondary, sometimes tertiary role in the formation of a community's laws and customs. At the same time, the majority of people expect fair and equitable rules from the legislator. In earlier epochs, Christian morality and theology played a central role in the formation of European politics, and thus also in legislation. Can Christian morality help to reconcile the needs of citizens for fair and equitable rules with the apparently pragmatic nature of politics? If so, how? What solutions can it provide to old and new problems?
