It is that wherein the emperor rules with an amplitude of authority such as Constantine and Justinian held, whose successor he claims to be; where, also, an imperial aide-de-camp, booted and spurred, sits at the council board of a synod called holy, and is by far the most important member of it, for nothing can pass without his sanction--a synod which rules the bishops, being itself nothing but a ministry of the State, drawing, like the council of the empire, its jurisdiction from the emperor. Justinian was a true successor of the great Theodosius in so far as he upheld orthodoxy, and endeavoured to unite all his subjects in one belief and one centre of unity. The greatest of the Roman emperors had for their first and chief motive, in upholding this first principle of imperial policy, the conviction that thus only they could hope to maintain the peace and security of the empire. Schism in the Church betokened rebellion in the State. In the fourth century heresy had driven the empire to the very brink of destruction. Besides this, all the populations converted from heathendom were accustomed to see a complete harmony between religion and the State, which appeared almost blent into one. Again, we must not forget that at this time the Christian religion had been lately accepted distinctly as a divine institution, and that it embraced the whole man with a plenitude of power which the indifference and division of our own times hardly allow us to conceive. Those who would realise this grasp of the Christian faith, transforming and exalting the whole being, may reach a faint perception of it by reading the great Fathers of the fourth and fifth centuries--St. Basil, St. Ambrose, St. Chrysostom, St. Jerome, St. Augustine, and St. Leo. They were not in danger of taking the moral corruption of an effete civilisation for the Christian faith. Again, the emperors, living in the midst of this immense intellectual and moral power--for instance, Justinian himself practising in a court the austerities of a monastery--recognised the confession of the same faith as the strongest band which united subjects with their prince. They thought that those who were not united with them in belief could not serve them with perfect love and fidelity. And, lastly, they hoped that their own zeal in maintaining the Church's unity unimpaired would make them worthier of the divine favour, and give success to all their undertakings. Let us take the words of Theodosius, one of the greatest and best among them, to his colleague the younger Valentinian, who up to the time of his mother Justina's death had been unjust to the Catholic cause and favoured the Arian heresy: "The imperial dignity is supported, not by arms, but by the justice of the cause. Emperors who feared God have won victories without armies, have subdued enemies and made them tributary, and have escaped all dangers. So Constantine the Great overcame the tyrant Licinius in a sea-fight. So thy
