Meh.
Christians aren't political Anabaptists. That's the first thing. The second thing is this:
"If you don’t want Christian nationalism, what kind of nationalism do you want? And if it’s not the Christianity that’s the problem, is it the nationalism? … if we don’t want nationalism, do we want globalism?” - Voddy Baucum
Those are the choices before us, My Lord Bishop, and Anglicans, following Roman Catholics and Eastern Orthodox, have historically understood the necessity of the symphonia between the Christian Church and the Christian State. Now, I do believe that American republicanism arguably addresses some of the abuses of European Christan nations, but republics are fragile things, as Benjamin Franklin noted, echoing the concerns of other Founding Fathers. However, for someone to suggest that Christians should abandon the public square, and even to suggest that the secularist status quo is acceptable, is to embrace the worst form of political folly. It is not only wholly ahistorical, but dangerous.
No, we must embrace the reality that what remains of Christendom is the yeast of a restored Christian culture, and all that entails politically. In the words of T.S. Eliot:
“The World is trying the experiment of attempting to form a civilized but non-Christian mentality. The experiment will fail; but we must be very patient in awaiting its collapse; meanwhile redeeming the time: so that the Faith may be preserved alive through the dark ages before us; to renew and rebuild civilization, and save the World from suicide.”
