The Tom Wright lecture mentioned last week can now be downloaded here (scroll down to find the link). It's well worth reading carefully and even using as the basis for a group discussion in church in the run up to the election.
Wright's lecture is a robust analysis of the issues facing British democracy seen through the lens of the Biblical narrative and the post-enlightenment history of the West. There's nothing in the lecture about the biblical story and especially that of Jesus as the bringer of the Kingdom that is emphatically for this world, for the here and now, that we haven't read in Wright before. But here it's delivered as a brief and accessible overview that's then applied to how Christians might think about the contemporary political process.
