Political theology is a branch of both political philosophy and theology that investigates the ways in which theological concepts or ways of thinking underlie political, social, economic and cultural discourses. Though the relationship between Christianity and politics has been debated since the time of Jesus, political theology as an academic discipline arose in the latter part of the 20th century, partially as a response to the work of both Carl Schmitt and the Frankfurt School. The journal Political Theology currently examines this interface of religious faith and politics.
Writing amidst the turbulence of the German Weimar Republic, Carl Schmitt argued in Political Theology that the central concepts of modern politics were secularized versions of older theological concepts. Drawing on Thomas Hobbes in Leviathan he argued that the state exists to maintain its own integrity in order to ensure order in society in times of crisis, draws on the theological anthropology of illiberal pessimism of Juan Donoso Cortes in arguing for the essentially "dangerous", strife-ridden essence of humankind, and polemicized against modern democratic pluralist theory, supposedly, for failing to understand the propounded Hobbesian insight "men and arms, not words and promises, make the force and power of the laws."
With the exception of Schmitt, much of political theology’s roots can be traced to discussions of the relationship of ethics and religion. The influence of Hegel is also evident throughout much of political theology including the theology developed by the Catholic theologian Johann Baptist Metz. Metz explored the concept of political theology throughout his work. He argued for the concept of a 'suffering God' who shared the pain of his creation, writing, "Yet, faced with conditions in God's creation that cry out to heaven, how can the theology of the creator God avoid the suspicion of apathy unless it takes up the language of a suffering God?" This leads Metz to develop a theology that is tied to Marxism. He levels a fierce critique of what he calls bourgeois Christianity and believes that the Christian Gospel has become less credible because it has become entangled with bourgeois religion. His work Faith in History and Society develops apologetics, or fundamental theology, from this perspective.
Two of the other major figures in the early development of political theology were Jurgen Moltmann and Dorothee Solle. Like in Metz' work, the concept of a suffering God is key to Moltmann's theological program. Moltmann's political theology was strongly influenced the Marxist philosopher Ernst Bloch, and both Moltmann and Solle were influenced heavily by liberation theology, as was Metz. Another early influence was the Frankfurt School of critical theory, especially Walter Benjamin, and the Frankfurt School's broader critique of modernity.
Reinhold Niebuhr also developed a theology similar to Metz in the practical application of theology. During the 1930s, Niebuhr was a leader of the Socialist Party of America, and although he broke with the party later in life socialist thought is a prominent component of his development of Christian Realism. The work by Niebuhr that best exemplifies his relationship with political theology is Moral Man and Immoral Society: A Study of Ethics and Politics (1932).
One of the most influential figures in recent political theology is Stanley Hauerwas, though he considers his work to be better termed a "theological politics". Hauerwas has actively critiqued the political theology of both Reinhold Niebuhr and H. Richard Niebuhr, and has been a frequently critic of Christians' attempt to attain political power and align themselves with secular political ideologies. Moreoever, he has been a severe critic of liberal democracy, capitalism, and militarism, arguing that all of those ideologies are antithetical to Christian convictions.
Many leading non-Christian thinkers have written extensively on the topic of political theology in recent years, such as Jurgen Habermas, Giorgio Agamben, Simon Critchley, and Slavoj Zizek.
The term political theology has been used in a wide variety of ways by writers exploring different aspects of the subject, with tension developing between those advocating a traditional concern with individual "moral reform", such as Clyde Wilcox's God's Warriors (1992) and Ted Jelen's The Political World of the Clergy (1993), and those on the left who focus on collective "social justice", e.g. Jeffrey K. Hadden's The Gathering Storm in the Churches (1969) and Harold Quinley's The Prophetic Clergy (1974).
