On the whole, then, we have reason to say, that if there be a form of Christianity at this day distinguished for its careful organization, and its consequent power; if it is spread over the world; if it is conspicuous for zealous maintenance of its own creed; if it is intolerant towards what it considers error; if it is engaged in ceaseless war with all other bodies called Christian; if it, and it alone, is called "Catholic" by the world, nay, by those very bodies, and if it makes much of the title; if it names them heretics, and warns them of coming woe, and calls on them one by one, to come over to itself, overlooking every other tie; and if they, on the other hand, call it seducer, harlot, apostate, Antichrist, devil; if, however much they differ one with another, they consider it their common enemy; if they strive to unite together against it, and cannot; if they are but local; if they continually subdivide, and it remains one; if they fall one after another, and make way for new sects, and it remains the same; such a religious communion is not unlike historical Christianity, as it comes before us at the Nicene Era. SECTION III. THE CHURCH OF THE FIFTH AND SIXTH CENTURIES. The patronage extended by the first Christian Emperors to Arianism, its adoption by the barbarians who succeeded to their power, the subsequent expulsion of all heresy beyond the limits of the Empire, and then again the Monophysite tendencies of Egypt and part of Syria, changed in some measure the aspect of the Church, and claim our further attention. It was still a body in possession, or approximating to the possession, of the _orbis terrarum_; but it was not simply intermixed with sectaries, as we have been surveying it in the earlier periods, rather it lay between or over against large schisms. That same vast Association, which, and which only, had existed from the first, which had been identified by all parties with Christianity, which had been ever called Catholic by people and by laws, took a different shape; collected itself in far greater strength on some points of her extended territory than on others; possessed whole kingdoms with scarcely a rival; lost others partially or wholly, temporarily or for good; was stemmed in its course here or there by external obstacles; and was defied by heresy, in a substantive shape and in mass, from foreign lands, and with the support of the temporal power. Thus not to mention the Arianism of the Eastern Empire in the fourth century, the whole of the West was possessed by the same heresy in the fifth; and nearly the whole of Asia, east of the Euphrates, as far as it was Christian, by the Nestorians, in the centuries which followed; while the Monophysites had almost the possession of Egypt, and at times of the whole Eastern Church. I think it no assumption to call Arianism, Nestorianism, and Eutychianism heresies, or to identify the contemporary Catholic Church with Christianity.
