But the Greeks and Bulgarians, jealous for their native priesthood, demanded by what authority the see of Rome claimed jurisdiction over the Old and New Epirus, Thessaly, and Dardania, the country now called Bulgaria. For more than four centuries there had been occasional jealousies between these two churches; certain articles of faith continued subjects of difference; and the questions of temporal and spiritual precedence made them ever watchful. History records that, as early as 606, Phocas, having ascended the imperial throne, treading upon the dead bodies of the Emperor Mauritius, his children and friends,—Cyriacus, the patriarch, exposed to his view the enormity of his crimes, and most zealously exhorted to repentance. The supremacy of order and dignity was instantly granted to the patriarch of Rome, in the person of Boniface III. But his successors, their historians say, wisely refused, disclaimed the favour of Phocas, but claimed it as a Divine right derived from St. Peter. Thus commenced and was made final the severance of the Greek and Roman churches. But the loss of spiritual rule in the east was accompanied by an enlargement of temporal power in the west. Upon the death of Hadrian, John, the son of Gundo, succeeded to the papal chair; and, upon the demise of Lewis II., (876,) his uncles, Lewis, king of Germany, and Charles the Bald, king of France, were rivals for the vacant throne. Charles and Hadrian were ever at variance. But, seizing upon the moment, because he was more ready at hand, or more yielding to his wishes, John invoked him instantly at Rome, received him with loudest acclamations, and crowned him emperor, just seventy-five years to a day from the elevation of Charlemagne to the Western Empire. Upon this occasion, Pope John announced that he had elected him emperor in conformity to the revealed will of God; that his act of crowning him made him such; and that the sceptre, under God, was his free gift. This new doctrine was assented to by Charles, and ever after claimed as one of the powers of the pope of Rome. Thus the church of Rome became wholly separated from the Eastern Empire,—“freely losing its hold on a decayed tree, to graft itself upon a wild and vigorous sapling.” _D'Aubigne._ Eutropius, the Lombard, informs us of the rich presents made to St. Peter for these favours of the pope, and that the emperor ceded to him the dukedoms, Benevento and Spoleti, together with the sovereignty of Rome itself.
