This term is used among Christians to denote those who form separate communions, and do not associate with one another in religious worship and ceremonies. Thus we call Papists, Lutherans, Calvinists, different sects, not so much on account of their differences in opinion, as because they have established to themselves different fraternities, to which, in what regards public worship, they confine themselves; the several denominations above mentioned having no intercommunity with one another in sacred matters. High, Strict, and Moderate Calvinists, High Church and Low Church, we call only parties, because they have not formed separate communions. Great and known differences in opinion, when followed by no external breach in the society, are not considered constituting distinct sects, though their differences in opinion may give rise to mutual aversion.

The Jewish, Christian, Mahometan, and Pagan world is divided into an almost innumerable variety of sects, each claiming to themselves the title of orthodox, and each charging their opponents with heresy.

Where perfect religious liberty prevails, as in the United States, and where emigrants from all quarters of the globe resort in great numbers, it is not surprising that most of the Christian sects in foreign countries, with some of native origin, should be found in this part of the American continent.
