To remedy the evil, Gregory issued a decree that no ecclesiastic should do homage to a temporal lord, but that he should receive the ring and staff, the symbols of investiture, from the hands of the Pope alone. Any one who should dare disobey the decree was threatened with the anathemas of the Church.
Such was the bold measure by which Gregory proposed to wrest out of the hands of the feudal lords and princes the vast patronage and immense revenues resulting from the relation they had gradually come to sustain to a large portion of the lands and riches of the Church. To realize the magnitude of the proposed revolution, we must bear in mind that the Church at this time was in possession of probably one-half of the lands of Europe.
EXCOMMUNICATIONS AND INTERDICTS.—The principal instruments relied upon by
Gregory for the carrying out of his reforms were Excommunication and
Interdict.
The first was directed against individuals. The person excommunicated was cut off from all relations with his fellow-men. If a king, his subjects were released from their oath of allegiance. Any one providing the accursed with food or shelter incurred the wrath of the Church. The Interdict was directed against a city, province, or kingdom. Throughout the region under this ban, the churches were closed; no bell could be rung, no marriage celebrated, no burial ceremony performed. The rites of baptism and extreme unction alone could be administered. These spiritual punishments rarely failed during the eleventh and twelfth centuries in bringing the most contumacious offender to a speedy and abject confession. This will appear in the following paragraph.
GREGORY VII. AND HENRY IV. OF GERMANY.—The decree of Gregory respecting the relation of the clergy to the feudal lords created a perfect storm of opposition, not only among the temporal princes and sovereigns of Europe, but also among the clergy themselves. The dispute thus begun distracted Europe for centuries.
Gregory experienced the most formidable opposition to his reforms in Germany. The Emperor Henry IV. refused to recognize his decree, and even called a council of the clergy of Germany and deposed him. Gregory in turn gathered a council at Rome, and deposed and excommunicated the emperor. This encouraged a revolt on the part of some of Henry's discontented subjects. He was shunned as a man accursed by heaven. His authority seemed to have slipped entirely out of his hands, and his kingdom was on the point of going to pieces. In this wretched state of his affairs there was but one thing for him to do,—to go to Gregory, and humbly sue for pardon and re-instatement in the favor of the Church.
Henry sought the Pontiff at Canossa among the Apennines. But Gregory refused to admit the penitent to his presence. It was winter, and for three successive days the king, clothed in sackcloth, stood with bare feet in the snow of the court-yard of the palace, waiting for permission to kneel at the feet of the Pontiff and to receive forgiveness. On the fourth day the penitent king was admitted to the presence of Gregory, who re- instated him in favor—to the extent of removing the sentence of excommunication (1077).
Henry afterwards avenged his humiliation. He raised an army, invaded Italy, and drove Gregory into exile at Salerno, where he died. His last words were, "I have loved justice and hated iniquity, and therefore I die in exile" (1085),
But the quarrel did not end here. It was taken up by the successors of Gregory, and Henry was again excommunicated. After maintaining a long struggle with the power of the Church, and with his own sons, who were incited to rebel against him, he at last died of a broken heart (1106).
THE POPES AND THE HOHENSTAUFEN EMPERORS.—In the twelfth century began the long and fierce contention—lasting more than a hundred years—between the Papal See and the emperors of the proud House of Hohenstaufen (see p. 504). It was simply the continuation and culmination of the struggle begun long before to decide which should be supreme, the "world-priest" or the "world-king." The outcome was the final triumph of the Roman bishops and the utter ruin of the Hohenstaufen.
