Christianity in the 6th century

In 6th century Christianity, Roman Emperor Justinian launched a military campaign in Constantinople to reclaim the western provinces from the Germans, starting with North Africa and proceeding to Italy. Though he was temporarily successful in recapturing much of the western Mediterranean he destroyed the urban centers and permanently ruined the economies in much of the West. Rome and other cities were abandoned. In the coming centuries the Western Church, as virtually the only surviving Roman institution in the West, became the only remaining link to Greek culture and civilization.

In the East, Roman imperial rule continued through the period historians now call the Byzantine Empire. Even in the West, where imperial political control gradually declined, distinctly Roman culture continued long afterwards; thus historians today prefer to speak of a "transformation of the Roman world" rather than a "Fall of Rome." The advent of the Early Middle Ages was a gradual and often localised process whereby, in the West, rural areas became power centres whilst urban areas declined. Although the greater number of Christians remained in the East, the developments in the West would set the stage for major developments in the Christian world during the later Middle Ages.

Prior to the Second Council of Constantinople was a prolonged controversy over the treatment of three subjects, all considered sympathetic to Nestorianism, the heresy that there are two separate persons in the Incarnation of Christ. Emperor Justinian condemned the Three Chapters, hoping to appeal to monophysite Christians with his anti-Nestorian zeal. Monophysites believe that in the Incarnate Christ there is one nature, not two. Eastern patriarchs supported the emperor, but in the West his interference was resented, and Pope Vigilius resisted his edict on the grounds that it opposed the Chalcedonian decrees. Justinian's policy was in fact an attack on Antiochene theology and the decisions of Chalcedon. The pope assented and condemned the Three Chapters, but protests in the West caused him to retract his condemnation. The emperor called the Second Council of Constantinople to resolve the controversy.
