If conservatives value variety, why do conservative Roman Catholics insist on church unity? Russell Kirk said that true conservatives actually appreciate difference and pluriformity:
[C]onservatives pay attention to the principle of variety. They feel affection for the proliferating intricacy of long-established social institutions and modes of life, as distinguished from the narrowing uniformity and deadening egalitarianism of radical systems. For the preservation of a healthy diversity in any civilization, there must survive orders and classes, differences in material condition, and many sorts of inequality. The only true forms of equality are equality at the Last Judgment and equality before a just court of law; all other attempts at levelling must lead, at best, to social stagnation. Society requires honest and able leadership; and if natural and institutional differences are destroyed, presently some tyrant or host of squalid oligarchs will create new forms of inequality.
Maybe that makes John Turner a conservative who is not going along with the Reformation as tragedy because it divided the church:
First and foremost, there was no good reason for the primacy of the Bishop of Rome in the first place. Jesus bestowed the keys of the kingdom on Peter, but it seems clear from the Book of Acts and the Pauline epistles that Peter hardly exercised anything like papal authority in the early church. The historical evidence for Peter becoming the first bishop of Rome (or even being in the city) is unconvincing to one not already convinced. While Protestants obviously sundered the institutional unity of the Western church, it was a sort of unity unauthorized by scripture and unwarranted by the circumstances of the early church. (It also seems snarky but necessary to mention that Rome bore considerable responsibility for the Great Schism between East and West that preceded the Reformation by a half-millennium).
Second, it is not at all clear to me that Jesus’s prayer for Christian unity means that Jesus wanted his church to have an institutional, hierarchical unity along the lines of either the late-medieval or contemporary Catholic Church. The Book of Acts suggests that the apostles in Jerusalem exercised a measured primacy among early Christians, but for the most part Christianity spread around the Mediterranean world and to the East in a way that fostered local autonomy and diversity. This diversity of theologies and even collections of scripture alarmed many Christians, some of whom identified many strands of Christianity as heresy. By the fourth century, newly tolerated and then established Christianity sought to impose theological order on this chaos. The result was the institutionally useful but not terribly New Testament idea that all Christians had to have essentially the same understanding of Jesus Christ and of the relationship among the members of the Trinity. Getting at least most Christians to assent to the fourth- and fifth-century creeds took a considerable amount of viciousness and sometimes violence.
So it’s the church unitedists who also likely go for the United Nations and the European Union (even while in some parts of the world arguing for a “two-state” solution).
