While there is a growing body of literature that demonstrates Christianity’s influence on the theoretical foundations of International Relations, or on its influence upon key authors, there is very little work that seeks to explore the influence of Christian Scripture on the discipline. While this might be expected, (biblical interpretation can be contentious, and International Relations scholars who are already sceptical about the place of religion in the discipline are going to be even less receptive to an analysis of biblical texts), the paucity of analyses that provide even a rudimentary discussion of such an important aspect of the Christian religion is deeply problematic. This paper seeks to fill that gap, by supplementing existing International Political Theology (IPT) with seven biblical presuppositions that support it. It begins with a short survey of the IPT literature, before turning to seven biblical presuppositions: a caveat (the historical death and resurrection of Christ), three presuppositions about the world (the world is created, the world is created social and moral and therefore political, the world is created ordered), and three presuppositions about politics, (derivative political authority, secular political authority, and judicial political authority). The result will be a more comprehensive and robust IPT.
