The purpose of this qualitative study is to examine how and why the Christian right in America from the 1980s until today has tried to affect and influence the public and political sphere in the country. This has been done by analyzing five books from prominent Christian leaders during the different decades. The study answers three main questions: Why has the Christian right in the US become increasingly politically active with a desire to implement their values in the public sphere, and what ideas and ideologies is this based on? How can we understand the emergence and change of the Christian right’s political engagement from the 1980s until today? What ideological and rhetorical strategies has the Christian right used to legitimize its role in the public and political sphere? The result of the study shows that the Christian right bases their beliefs on an old idea that the country was founded on Christian principles where God had blessed the nation to have an exceptional status in the world. The Christian right believes that because of a breakdown of these Christian principles and values, the country is on the brink of a national disaster. There are a couple of questions that sit at the heart of this group’s will to mobilize, which are abortion and traditional family structures, along with other contemporary questions that each decade faces. All these questions are based on the Christian right’s view and definition of morality and freedom.
