Thirty years after the Sixth Council the patriarch, John V., after presiding at the council summoned by the Emperor Philippicus, who attempted by it to re-establish the Monothelite heresy, besought pardon of Pope Constantine as the head whose function it was to heal all the wounds of the body. I know not what proof of the Roman primacy surpasses in force, to those who have eyes to see, this proof arising from the alternate persecution and confession of Byzantine emperors and patriarchs, compared with the unbending fortitude and unalterable faith of the twenty-four Popes in that long century when Rome served as a slave in the natural order, and was worshipped in the spiritual kingdom as a sanctuary. CHAPTER VI. AN EMPEROR PRIEST AND FOUR GREAT POPES. The Sixth General Council had been held in 680, and on the union of the East and West the long and obstinate Monothelite heresy had seemed to be extinguished with all the authority wielded by the Pope at the head of a General Council. Yet thirty years after this event the fifth emperor of the line of Heraclius was dethroned and beheaded by a usurper; and the first act of the insurgent when seated on the throne of Constantine was to call a council of his own eastern bishops at Constantinople, which at his command attempted to abrogate the Sixth Council and to set up again as the proper faith of the Church the heresy which it had condemned. And this act of Philippicus Bardanes met with nothing like an adequate resistance from the eastern bishops. It is true that the patriarch Cyrus, refusing to comply with the wishes of the new emperor, was deposed by him, and a more obsequious successor, the deacon John, put in his place. But even Germanus, then archbishop of Cyzicus, yielded to the storm, and thus a bishop of imperial blood, who four years afterwards was himself placed in the see of Constantinople, who held it during fifteen years, and then was deposed because he would not yield to the heretical measures of another emperor, is said to have been subservient to the will of Philippicus Bardanes. No incident can show more plainly the pretensions of the eastern emperor and the weakness of the eastern bishops than the fact that the first act of an Armenian officer when he had, by the murder of his sovereign, put on the imperial buskins on which the eagle of the Roman power was embroidered, consisted in an attempt to alter the faith of the Church, and that the alteration was supported by the bishops whom he had convened. Philippicus himself was a worthless sensualist, whose reign was put an end to in eighteen months by another revolution. Two more transient emperors passed to the dishonoured throne, and then appeared a third, who reigned twenty-four years, and has left his mark on history.
