The aspiration to find a theological perspective from which to view political life is a very old one. The converse – seeking to view theology from a political perspective – is new. It is one indication, perhaps, of an important cultural reversal of religion and politics. In what, retrospectively, has come to be known as ‘Christendom’, people subjected political philosophies to the test of faithfulness to biblical truth because, they supposed, the ways of politics are, and should be, subservient to the ways of God. In the long shadow of the French Revolution, however, democratic consensus and human rights have become the touchstones by which religious practices, and even Christian doctrines, are commonly assessed and regulated. In short, the content of anything called a ‘Christian’ political philosophy is judged acceptable or unacceptable by secular standards.
