To you, most blessed father, and to all your Catholic successors, and to the Holy Roman Church, our special mother, we shall discharge all obedience, honour, and reverence, always with an humble heart and a devout spirit, as our Catholic predecessors, kings and Emperors, are known to have done to your predecessors; not a whit from these shall we take away, rather add, that our devotion may shine the more."[11] Frederick promised that he would not interfere in the election of bishops, and that the candidate canonically elected should be installed. He confirmed the papal title to the Papal States. "I vow, promise, swear, and take my oath to protect and preserve all the possessions, honours, and rights of the Roman Church, in good faith, to the best of my power" (1213). From this time forward Frederick advanced from success to success. Otto was driven into private life, and the Pope's legate put the German crown on Frederick's head at Aachen (1215). Where Innocent blessed, success and prosperity followed; where he cursed, death and destruction came. Elsewhere the Pope was equally triumphant. All Europe bent under his imperial decrees. The kings of Portugal, Leon, Castile, and Navarre were scolded or punished. The King of Aragon went to Rome and swore allegiance. The Duke of Bohemia was rebuked, the King of Denmark comforted, the nobles of Iceland warned, the King of Hungary admonished. Servia, Bulgaria, even remote Armenia, received papal supervision and paternal care. Philip Augustus of France, at Innocent's command, took back the wife whom he had repudiated. John of England grovelled on the ground before him, and yielded up "to our lord the Pope Innocent and his successors, all our kingdom of England and all our kingdom of Ireland to be held as a fief of the Holy See"(1213). Another triumph of darker hue added to the brilliance of Innocent's career. In the south of France, in the pleasant places of Provence and Languedoc, where troubadours praised love and war, and lords and ladies wandered down primrose paths, the humbler folk got hold of certain dangerous ideas. They believed that there was a power of evil as well as a power of good, that Christ was but an emanation from God, that the God of the Jews was not the real God of Goodness, and, worse than all, that the Roman Church, with its sacerdotalism, forms, sacraments, and ritual, was, to say the least, not what it should be. Innocent entertained no doubts that the Roman Church had been founded by God to maintain His truth on earth; as a statesman he regarded heresy as we regard treason and anarchy; as a priest he deemed it sin. He called Simon of Montfort and other dogs of war from the north and urged them at the quarry. The heresy was put down in blood. Here appears the black figure of St. Dominic, encouraging the faithful, rallying the hesitant, and by the fervour of his belief, by his devotion, by his genius for organization, more destructive to heresy than the sword of Montfort.
