Why does Peter Leithart find this encouraging, uplifting, or persuasive? Why does the inadequacy of secularism somehow prove the sufficiency of God-drenched conceptions of the world?
The task is not simply to expose the inadequacy of a world without God or to show the collaborative spirit of religious engagement in the common good. It surely must more specifically be to demonstrate the unique power and thrilling wisdom of the logic of God in Christ and to reconceive tired issues in the light of the shape of Christ’s coming. The authority and the credibility of the public theology rest not so much on the theologian’s insight, intelligence, or subtle grasp of complex issues (wondrous as each may be) as on the ability – respectfully, lucidly, and accessibly – to show how Christ redefines human nature, transforms death, and overturns the givens of life; to show what only God can do and only God has done; and more intriguingly, to highlight the way that questions in public life today reflect and recall issues faced by the church in shaping and embodying Christian doctrine.
Who said secularism was going to figure it all out? Who says that Christendom ever did? In fact, if Peter Heather is correct about the appeal of the Roman Empire to Christian Emperors — Constantine, Justinian, and Charlemagne — then the European world even in its most Christian phase was responsible for a lot of senseless war:
. . . a restored empire that captured the essence of the Roman original had become completely impossible by the year 1000. Not only had Islam broken apart ancient Mediterranean unity, and the balance of power in Western Europe shifted decisively north of the Alps, but, still more fundamentally, patterns of development were now much too equal across the broader European landscape. Thanks to this equalization of development, you might say, the scene was set for the thousand subsequent years of fruitless warfare which followed as Europe’s dynasts intermittently struggled to achieve a level of overarching dominance that was in fact impossible. In that sense, it took the nightmare of two world wars in the twentieth century before the European Dream was finally called into existence to try to put a stop to the process of endless armed competition between powers that were always too equal for there to be an outright winner. (The Restoration of Rome, 294-295)
And let’s be clear, these were dynasts with Christian motivations (at least in part — Hegel’s w-w had not come along yet). So why does Leithart think that putting God into the questions surrounding public life will do any good? This time, he thinks, the politicians, inspired by his guy Constantine, will get it right?
And if anyone ever wants to argue for Christendom as an example of politics accomplished Christianly, or that the Christian society secured human flourishing, s/he should merely consider the fundamental dynamic of medieval monarchy — gain control and keep it by taxation, warfare (and don’t forget leaving behind an undisputed heir). According to Heather:
In the small-state world of early medieval Europe, expansionary warfare replaced large-scale taxation as the source of renewable wealth that was necessary to maintaining a powerful central authority in anything but the very shortest of terms. . . . All of which prompts one final question: if expansion was so crucial to the longer-term exercise of central authority, filling the massive gap in royal finance created by the end of taxation, why did later Carolingian monarch allow it to end? . . . A more profitable route into the problem is to consider expansionary warfare in terms of cost-benefit equations which governed it. Expansionary warfare would bring in profits, but also involved costs, not just in financial terms (food, weaponry, etc.), but also in personal terms since some of those participating would certainly die. If you think about it in this way, then the ideal profile of an area ripe for expansion is easy enough to construct: it needs to be economically developed enough to offer a satisfying level of reward both in terms of moveable booty and potential land-grabbing, but militarily not so well organized that too many of your expeditionary army, on average, are going to die winning access to the prize. . . . On every corner of the frontier, the cost-benefit equation was starting to deliver a negative answer, either because the enemy was too formidable (Spain), or because the likely benefits were not that great (the Balkans), or some combination of the two (southern Italy and the Southern Elbe region). (288-90)
When you think about empire and government in those terms, the modern secular nation-state surely does seem to have its advantages. That’s not because it doesn’t go to war or because it’s run by a bunch of virtucrats. Instead, say what you will about capitalism and its appeal to baser human motivations, it does generate the kind of internal wealth that many times prevents nation-states from having to conquer another people who will pay the government’s bills. Not to mention that constitutionalism and enumerated powers are a much better way of gaining consent than intimidation by force (cheaper too).
