That which was begun by the foundation of Constantinople, was completed by the partition of the empire between the sons of Constantine. There are now two Roman worlds, a Greek, and a Latin. In one respect, Rome lost in dignity, she was no longer the sole metropolis of the empire; the East no longer treated her with the deference of a subject. On the other hand, she was the uncontested, unrivalled head of her own hemisphere; she had no rival in those provinces, which yet held her allegiance, either as to civil or religious supremacy. The separation of the empire was not more complete between the sons of Constantine or Theodosius, than between Greek and Latin Christianity.[b]
[42-395 A.D.]
The advance of Christianity involved an emancipation of religion from all political elements, and this was inevitably followed by the establishment of a distinct ecclesiastical body, with a constitution peculiar to itself. In this separation of the church from the state consists, perhaps, the most important and most effectually influential peculiarity of Christian times. The spiritual and temporal powers may come into close contact—they may remain in the most intimate communion; but a perfect coalition can only take place occasionally, and for short periods of time. In their reciprocal relations and position with regard to each other, has since then been involved one of the most important questions presented by all history.

It was nevertheless imperative on the ecclesiastical body to form their constitution on the model of that of the empire; and accordingly the hierarchy of the bishops, metropolitan patriarchs, was formed in close correspondence with the degradations of the civil power. No long time had elapsed before the bishops of Rome acquired the supremacy. It is, indeed, a vain pretence to assert that this supremacy was universally acknowledged by East and West, even in the first century, or, indeed, at any time; but it is equally certain that they quickly gained a pre-eminence, raising them far above all other ecclesiastical dignitaries. Many causes concurred to secure them this position; for if the relative importance of each provincial capital secured to its bishop a corresponding weight and dignity, how much more certainly would this result take place as regarded the ancient capital of the empire—that city whence the whole had derived its name? Rome was, besides, one of the most illustrious seats of the apostles; here had the greater number of the martyrs shed their blood. The bishops of Rome had displayed the most undaunted firmness throughout the different persecutions, and had sometimes been scarcely installed in their sacred office before they followed their predecessor in the path of that martyrdom by which his seat had been vacated. In addition to all this, the emperors now found it advisable to favour the advancement of a great patriarchal authority. In a law that became decisive for the predominance of Rome as well as of Christianity, Theodosius the Great commands that all nations claiming the protection of his grace should receive the faith as propounded by St. Peter to the Romans. Valentinian also forbade the bishops, whether of Gaul or of other provinces, to depart from the received customs of the church without the sanction of that venerable man, the pope of the Holy City. Thenceforth the power of the Roman bishops advanced beneath the protection of the emperor himself. But in this political connection lay also a restrictive force; had there been but one emperor, a universal primacy might also have established itself; but this was prevented by the partition of the empire. The emperors of the East were too eagerly tenacious of their ecclesiastical rights to make it possible that they should promote the extension of power desired by the western patriarchs in their dominions. In this respect also the constitution of the church presents the closest resemblance to that of the empire.

[312-754 A.D.]
Scarcely was this great change completed, the Christian religion established, and the church founded, when new events of great importance took place; the Roman Empire, so long conquering and paramount, was now to see itself assailed by its neighbours; in its turn it was invaded and overcome.
