Here, for instance, in New England, we have a system of belief which goes by the name of Orthodoxy; which, however, is considered very heterodox _out_ of New England. The man who is thought sound by Andover is considered very unsound by Princeton. The General Assembly of the Presbyterian Church, in 1837, cut off four synods, containing some forty thousand members, because they were supposed not to be sound in doctrinal belief. But these excommunicated synods formed a New School Presbyterian Church, having its own orthodoxy. Andover considers itself more orthodox than Cambridge; but the New School Presbyterians think themselves more orthodox than Andover—the Old School Presbyterians think themselves more orthodox than the New School. But the most orthodox Protestant is called a heretic by the Roman Catholics. The Roman Catholics, again, are called heretics by the Greek Church. So that orthodoxy, in this sense, seems an impossible thing—something which, if it exists, can never be certainly ascertained. Whenever a body of believers assumes the name of Orthodox, intending thereby that they are right, and their opponents wrong, they evidently assume the very point in dispute. They commit the fallacy called in logic a _petitio principii_. They beg the question, instead of discussing it. They put will in the place of reason. They say, in the very title page of their book, in the first step of their argument, that their book is satisfactory and their argument conclusive. It would be more modest to wait till the discussion is concluded before they proceed thus to state what the conclusion is. This is an arrogance like that which the Church of Rome commits, in calling itself Catholic or Universal, while excluding more than half of Christendom from its communion.(3) A political party does not offer such an affront to its opponents. It may name itself Democratic, Republican, Federal; it may call itself the Conservative party, or that of Reform. By these titles it indicates its leading idea—it signifies that it bears the standard of reform, or that it stands by the old institutions of the country. But no political party ever takes a name signifying that it is all right and its opponents all wrong. This assumption was left to religious sects, and to those who consider humility the foundation of all the virtues. The term “Evangelical” is, perhaps, not as objectionable as Orthodox, though it carries with it a similar slur on those of other beliefs. It says, “We are they who believe the gospel of Christ; those who differ from us do not believe it.” It is like the assumption by some of the Corinthians of the exclusive name of Christians. “We are of Christ,” said they—meaning that the followers of Paul and Apollos were not so.
