What exactly is political theology?

In his article, “A Guide to Political Theology: Its Key Concepts and Perspectives,” Jake Meador quotes me defining political theology as follows:

[Political theology refers to] a discipline of theology dedicated to applying the resources of Christian theology to the interests or questions of politics, i.e., how society is organized.

This includes exploring questions such as the origin, responsibility, and domain of government, the appropriate means of government (e.g., law, lethal coercion), the moral foundations of civil law, the relationship between church institutions and the state, the responsibility of Christians to the state and society, and the material and social implications of the gospel of the kingdom.
