Justinian has been declared to have forced upon the Empire which he had reunited the orthodoxy of S. Cyril and the Council of Chalcedon, and the attempt has been made to prove that Cyril himself was a Monophysite.[9] The best refutation of this view is the perfect harmony of the decisions of the Fifth General Council with those of the previous Oecumenical assemblies, and the fact that no novelty could be discovered to have been added to "the Faith" when the "Three Chapters" were condemned. With the close of the Council the definition of Christian doctrine passes into the background till the rise of the Monothelite controversy. When its decisions were accepted, the labours of Justinian had given peace to the churches. [Sidenote: and his successors.] From 565, when Justinian died, to 628, when Heraclius freed the Empire from the danger of Persian conquest, were years of comparative rest in the Church. It was a period of missionary extension, of quiet assertion of spiritual authority, in the midst of political trouble and disaster. Gibbon, who asserts that Justinian died a heretic, adds, "The reigns of his four successors, Justin, Tiberius, Maurice, and Phocas, are distinguished by a rare, though fortunate, vacancy in the ecclesiastical history {23} of the East"; and the sarcasm, though not wholly accurate, may serve to express the gradual progress of unity which marked the years up to the accession of Heraclius. The history of religion is concerned rather with those outside than those within the Church. That history we need not follow, and we may pass over this period with only a brief allusion to the development of independence outside the immediate range of the ecclesiastical power of New Rome. [Sidenote: Rise of separated bodies.] Heresies grew as an expression of national independence. The Chaldaean Church, which stretched to Persia and India, was Nestorian. The Monophysites won the Coptic Church of Egypt, the Abyssinian Church, the Jacobites in Syria, the Armenians in the heart of Asia Minor. In the mountains of Lebanon the Monothelites--of whom we have to speak shortly--organised the Maronite Church; and in Georgia the Church was aided by geographical conditions as well as historical development to ignore the overlordship of the Church of Antioch. So in Europe grew up with the new States, the Bulgarian, the Serbian, and the Wallachian Churches. [Sidenote: Missions and failures.]
