He was succeeded by two Popes, John IV. and Theodore, who behaved with the same decision and fortitude. But a new emperor had succeeded, after a frightful revolution, at twelve years of age; and a new patriarch of Constantinople was ready to draw up a new document for the heresy. It was met by another Pope, whose first act was to call a great Council at the Lateran, to condemn the heresy under anathema, and the two documents, of which the first was fathered by Heraclius, and the second by Constans II. For this act of courage St. Martin four years afterwards was stolen from Rome, judged at Constantinople as a traitor by the senate, and sent a prisoner to die of famine, as is believed, in the Crimea. The emperor, having Rome in full possession, used such means that Eugenius was put into the see while St. Martin was still living as a condemned criminal. But Eugenius could not be compelled to accept the heresy of the Byzantine monarch and patriarch. There follow five Popes, Vitalian, Adeodatus, Donus, Agatho, and Leo II. At length, when Constans had perished miserably in his bath at Syracuse, his son Constantine broke the line of heretical emperors. But he found in truth the heresy so embedded in his capital that he was obliged to act with great caution. After repulsing a Mohammedan attack upon his capital which lasted seven years, and was overcome only by the aid of the Greek fire, when if the city had been taken the Greek empire would have ended, and the patriarch of Constantinople have shared the lot of his brethren at Alexandria and Antioch, the emperor was enabled to invite Pope Donus to hold a Council at Constantinople which should terminate this long struggle. It was a struggle in which the whole West followed the Pope, but much of the East was in favour of the heresy. Pope Agatho had succeeded Donus; he accepted the request of the emperor, he had Councils held through the West, and a full patriarchal Council at Rome. So he appeared by his legates at Constantinople, and was welcomed with the words, “Peter has spoken by Agatho,” as 230 years before they cried, “Peter has spoken by Leo”. But Agatho also died before the Council had finished its work, and the tenth successor of Honorius, Leo II., during his short pontificate of ten months, set his seal upon the Council, and endured to censure a predecessor for neglect of his office, and for allowing by that neglect a heresy to obtain a temporary success. Ten Popes in succession, one of them actually martyred, all of them vassals of absolute sovereigns, had during all this interval of forty years alone prevented the heresy being forced upon the Church. Four patriarchs of Constantinople in succession had fostered it; and four were together condemned. They were condemned, not for negligence in allowing others to spread the heresy, but as its originators; as advisers and mouthpiece of emperors, all whose power had been bent by them to extort approval of it from Popes, who in their civil
