In this thought-provoking episode, we examine the intersection of global politics and political theology, focusing on the concept of "Security after Christendom." My guest, Professor John Heathershaw elucidates the meaning of "Christendom" and the significance of "security" in its aftermath.

The discussion then proceeds to examine the contrast between the modern world’s wealth and defense capabilities and the pervasive feelings of insecurity that are experienced. My guest offers insights from Christian theology on the global sense of insecurity in a secular age and discusses why notions of a new Christendom are considered idolatrous and harmful in today’s context.

In light of the rise of non-state actors and transnational movements, the discussion turns to the necessity of adapting theopolitical visions to remain relevant in shaping global politics. The ethical implications of a theopolitical approach to international relations are explored, particularly concerning humanitarian interventions and peacekeeping efforts. Lastly, we conclude by analysing the role of religion in the public sphere, especially in secular societies and speculate about the future of international relations theories incorporating religious studies without compromising their secular analytical frameworks.
