In 553, a great council at Constantinople was convoked by Justinian, who was an amateur theologian, to discuss three small writings, called _the three chapters_, of which nothing is now known. There were also disputes on some passages of Origen. Vigilius, bishop of Rome, would have gone thither in person; but Justinian had him put in prison, and the Patriarch of Constantinople presided. No member of the Latin church attended; for at that time Greek was no longer understood in the West, which had become entirely barbarous. In 680, another general council at Constantinople was convoked by Constantine the bearded. This was the first council called by the Latins _in trullo_, because it was held in an apartment of the imperial palace. The emperor, himself, presided; on his right hand were the patriarchs of Constantinople and Antioch; on his left, the deputies from Rome and Jerusalem. It was there decided that Jesus Christ had two wills; and Pope Honorius I., was condemned as a Monothelite, i.e., as wishing Jesus Christ to have but one will. In 787, the second Council of Nice was convoked by Irene, in the name of the emperor Constantine, her son, whom she had deprived of his eyes. Her husband, Leo, had abolished the worship of images, as contrary to the simplicity of the primitive ages, and leading to idolatry. Irene re-established this worship; she herself spoke in the council, which was the only one held by a woman. Two legates from Pope Adrian V., attended, but did not speak, for they did not understand Greek: the patriarch did all. Seven years after, the Franks, having heard that a council at Constantinople had ordained the adoration of images, assemble, by order of Charles, son of Pepin, afterwards named Charlemagne, a very numerous council at Frankfort. Here the second Council of Nice is spoken of as "an impertinent and arrogant synod, held in Greece for the worshipping of pictures." In 842, a great council at Constantinople was convoked by the empress Theodora. The worship of images was solemnly established. The Greeks have still a feast in honor of this council, called the _orthodoxia_. Theodora did not preside. In 861, a great council at Constantinople, consisting of three hundred and eighteen bishops, was convoked by the emperor Michael. St. Ignatius, patriarch of Constantinople, is deposed, and Photius elected. In 866, another great council was held at Constantinople, in which Pope Nicholas III. is deposed for contumacy, and excommunicated. In 869 was another great council at Constantinople, in which Photius, in turn, is deposed and excommunicated, and St. Ignatius restored.
