George Weigel comments on the anniversary of the Edict of Milan (313). I agree with this (though leveling the dangers of coercion to Protestants and Roman Catholics when Inquisitions were a Roman Catholic reality until 1870 is a bit much):
The immediate effects of the Constantinian settlement, both good and ill, were limned with customary wit and literary skill by Evelyn Waugh in the novel Helena. After 313, the tombs of the martyrs were publicly honored; so were the martyr-confessors, often disfigured by torture, who emerged from the Christian underground to kiss each other’s wounds at the first ecumenical council. Before those heroes met at Nicaea in 325, though, grave theological questions had gotten ensnared up in imperial court intrigues and ecclesiastical politics. Later unions of altar and throne led to a general cultural forgetting of Lactantius’ wisdom, as the Church employed the “civil arm” to enforce orthodoxy. Protestantism proved no less vulnerable to the temptation to coercion than Catholicism and Orthodoxy; one might even argue that the seventeenth-century Peace of Westphalia, which ended the European wars of religion by establishing the principle of cuius regio eius religio (the prince’s religion is the people’s religion), reversed the accomplishments of the “Edict of Milan”—and was, in fact, the West’s first modern experiment in the totalitarian coercion of consciences.
But then he shows the addling effects of preoccupation with the political outcomes of faith:
Very few twenty-first-century Christians would welcome a return to state establishments of religion as the accepted norm. So however much the Constantinian settlement led Christianity into what some regard as a lengthy Babylonian captivity to state power, the “Edict of Milan” also affirmed truths that have proven stronger over time than the temptation to use Caesar for God’s work. Today’s challenge is quite different: it’s the temptation to let Caesar, in his various forms, reduce religious conviction to a privacy right of lifestyle choice.
What about when Christ’s followers reduce religious conviction to a privacy right? What Weigel doesn’t see is that the churches are as complicit in privatizing religion as the Obama administration. When Manhattan Declarationists, including Protestants, Roman Catholics, and Orthodox, defend religious freedom in the name of the gospel, when the Gospel Coalition understands its union of Presbyterians, Baptists, and independents as defending the gospel, or when participants at Vatican II recognize Muslims, Jews, and Protestants as on the way to salvation, the particularities of Christianity like baptism and the Lord’s supper fall into irrelevance almost as quickly as it takes to say the Pledge of Allegiance.
Now lest I fall prey to the same error of leveling George Weigel to President Obama’s status, I will grant that the Manhattan Declaration, the Gospel Coalition, and Vatican II mean/meant well. Then again, so does the president. And in both cases the means of grace, word, sacrament, and prayer, that I spend so much time defending (as part of my private responsibilities) make as much difference to the Declarationists, the Allies, and the Cardinals (and their ecumenical observers) as the Seventy-Sixers do to professional sports.
