2. The council of 553, the fifth ecumenical, grew out of the controversy of the "Three Chapters," an adequate account of which, up to the time of the council, may be found in the articles JUSTINIAN and VIGILIUS. The council convened, in response to the imperial summons, on the 4th of May 553. Of the 165 bishops who subscribed the acts all but the five or six from Egypt were Oriental; the pope, Vigilius, refused to attend (he had made his escape from Constantinople, and from his retreat in Chalcedon sent forth a vain protest against the council). The synod was utterly subservient to the emperor. The "Three Chapters" were condemned, and their authors, long dead, anathematized, without, however, derogating from the authority of the council of Chalcedon, which had given them a clean bill of orthodoxy. Vigilius was excommunicated, and his name erased from the diptychs. The Orthodox faith was set forth in fourteen anathemas. Opinion is divided as to whether Origen was condemned. His name occurs in the eleventh anathema, but some consider it an interpolation; Hefele defends the genuineness of the text, but finds no evidence for a special session against Origen, as some have conjectured. The council was confirmed by the emperor, and was generally received in the East. Vigilius was soon coerced into submission, but the West repudiated his pusillanimous surrender, and rejected the council. A schism ensued which lasted half a century and was not fully healed until the synod of Aquileia, about 700. But the ecumenicity of the council was generally acknowledged by 680. See Mansi ix. pp. 24-106, 149-658, 712-730; Hardouin iii. pp. 1-328, 331, 414, 524; Hefele, 2nd ed., ii. pp. 798-924 (English translation, iv. pp. 229-365). 3. The sixth ecumenical council, 680-681, which was convened by the emperor Constantine Pogonatus to terminate the Monothelitic controversy (see Monothelites). All the patriarchates were represented, Constantinople and Antioch by their bishops in person, the others by legates. The number of bishops present varied from 150 to 300. The council approved the first five ecumenical councils and reaffirmed the Nicene and "Niceno-Constantinopolitan" creeds. Monothelitism was unequivocally condemned; Christ was declared to have had "two natural wills and two natural operations, without division, conversion, separation or confusion." Prominent Monothelites, living or dead, were anathematized, in particular Sergius and his successors in the see of Constantinople, the former pope, Honorius, and Macarius, the patriarch of Antioch. An imperial decree confirmed the council, and commanded the acceptance of its doctrines under pain of severe punishment. The Monothelites took fright and fled to Syria, where they gradually formed the sect of the Maronites (q.v.).
