5. As with the churches, so with their bishops,--there was a recognized equality among them. Late in the second, and throughout the third century, however, marked distinctions and recognitions of rank arose among the bishops, those of large and wealthy cities assuming authority and dignity above that accorded by them to the bishops of the country provinces. The bishops of the largest cities or provinces, took to themselves the distinguishing title of Metropolitans,--(See Mosheim, "Eccl. Hist.," Cent. II, Part II, ch. 2:3; also Cent. IV, Part II, ch. 2:3, and compare Cent. I, Part II, ch. 2:14.) and assumed a power of presidency over the bishops of more limited jurisdiction. 6. The second century was marked by the custom of holding synods or church councils; the practice originated among the churches in Greece, and thence became general. These councils grew rapidly in power, so that in the third century we find them legislating for the churches, and directing by edict and command in matters which formerly had been left to the vote of the people. Needless to say that with such assumptions of authority came arrogance and tyranny in the government of the Church. As the form of church government changed more and more, many minor orders of clergy or church officers arose; thus in the third century we read of sub-deacons, acolytes, ostiars, readers, exorcists, and copiates. As an instance of the pride of office, it is worthy of note that a sub-deacon was forbidden to sit in the presence of a deacon without the latter's express consent. 7. Rome, so long the "mistress of the world" in secular affairs, arrogated to herself a pre-eminence in church matters, and the bishop of Rome claimed supremacy. It is doubtless true that the church at Rome was organized by Peter and Paul. Tradition, founded on error, said that the apostle Peter was the first bishop of Rome; and those who successively were acknowledged as bishops of the metropolis claimed to be, in fact, lineal successors of the presiding apostle. The high but none the less false claim is made by the Catholic Church in this day, that the present pope is the last lineal successor--not alone to the bishopric but to the apostleship. 8. The rightful supremacy of the bishops of Rome, or Roman pontiffs as they came to be known, was early questioned; and when Constantine made Byzantium, or Constantinople, the capital of the empire, the bishop of Constantinople claimed equality. The dispute divided the Church, and for five hundred years the dissension increased, until in the ninth century (855 A. D.) it developed into a great disruption, in consequence of which the bishop of Constantinople, known distinctively as the patriarch, disavowed all further allegiance to the bishop of Rome, otherwise known as the Roman pontiff. This disruption is marked today by the distinction between Roman Catholics.
