One of the perennial questions in political theology is how the concept of truth is defined and how such is grounded theologically. The answer to this determines, to a great degree, theological engagement with and appropriations of political systems and theological accounts of political and social order. Truth and Politics tackles this crucial question through an analysis and comparison of the thought of two of the most important contemporary Catholic and Protestant theologians, Joseph Ratzinger (Benedict XVI) and John Milbank. Peter Samuel Kucer here traces out the critical question of the relationship of theology and politics, particularly as it intersects with ecclesiology, through a focus on the issue of the theological relationship to socialism. In this, Kucer demonstrates the competing accounts in the theologies of Joseph Ratzinger and John Milbank, arguing that Ratzinger's theology is oriented in such a way that it maintains a provisional openness with regard to political forms in contrast to Milbank's work, which subscribes to a particular pattern of church and politics.
