Great struggles took place in the eleventh century, between the spiritual and temporal powers. England was the field of one branch of the combat, between Bishop and King; but this cannot be properly understood without reference to the main conflict in Italy, between Pope and Emperor.

The Pope, which word signifies Father, or Patriarch, of Rome, had from the Apostolic times been always elected, like all other bishops, by the general consent of the flock, both clergy and people; and, after the conversion of Constantine, the Emperor, as first lay member of the Church, of course had a powerful voice in the election, could reject any person of whom he disapproved, or nominate one whom he desired to see chosen, though still subject to the approval of clergy and people.

This power was, however, seldom exercised by the emperors at Rome, after the seat of empire had been transferred to Constantinople, and their power over Italy was diminishing through their own weakness and the German conquests. The election continued in the hands of the Romans, and in general, at this time, their choice was well-bestowed; the popes were, many of them, saintly men, and, by their wisdom and authority, often guarded Rome from the devastations with which it was threatened by the many barbarous nations who invaded Italy. So it continued until Pope Zaccaria quarrelled with Astolfo, King of Lombardy, and summoned the Carlovingian princes from France to protect him. These Italian wars resulted in Charles-le-Magne taking for himself the crown of Lombardy, and in his being chosen Roman Emperor of the West, by the citizens of Rome, under the influence of the Pope; while he, on his side, conferred on the pope temporal powers such as none of his predecessors had enjoyed.

From thenceforth the theory was, that the Pope was head of the Western Church, with archbishops, bishops, clergy, and laity, in regular gradations under him; while the Emperor was in like manner head of the State, kings, counts, barons, and peasants, in different orders below him; the Church ruling the souls, the State the bodies of men, and the two chieftains working hand in hand, each bearing a mission from above; the Emperor, as a layman, owning himself inferior to the Pope, yet the Pope acknowledging the temporal power of the crowned monarch.

This was a grand theory, but it fell grievously short in the practice. The city of Rome, with its worn-out civilization, was a most corrupt place; and now that the Papacy conferred the highest dignity and influence, it began to be sought by very different men, and by very different means, from those that had heretofore prevailed. Bribery and every atrocious influence swayed the elections, and the wickedness of some of the popes is almost incredible. At last the emperors interfered to check the dreadful crimes and profanity at Rome, and thus the nomination of the Pope fell absolutely into their hands, and was taken from the Romans, to whom it belonged.

In the earlier part of the eleventh century, a deacon of Rome, named Hildebrand, formed the design of freeing the See of St. Peter from the subjection of the emperors, and at the same time of saving it from the disgraceful power of the populace. The time was favorable, for the Emperor, Henry IV., was a child, and the Pope, Stephen II., was ready to forward all Hildebrand’s views.

In the year 1059 was held the famous Lateran Council [Footnote: So called from being convoked in the Church at the Lateran gate, on the spot where St. John was miraculously preserved from the boiling oil.] of the Roman clergy, in which it was enacted, that no benefice should be received from the hands of any layman, but that all bishops should be chosen by the clergy of the diocese; and though they in many cases held part of the royal lands, they were by no means to receive investiture from the sovereign, nor to pay homage. The tokens of investiture were the pastoral staff, fashioned like a shepherd’s crook, and the ring by which the Bishop was wedded to his See, and these were to be no longer taken from the monarch’s hands. The choice of the popes was given to the seventy cardinal or principal clergy of the diocese, who were chiefly the ministers of the different parish churches, and in their hands it has remained ever since.

Hildebrand himself was elected Pope in 1073, and took the name of Gregory VII. He bore the brunt of the battle by which it was necessary to secure the privileges he had asserted for the clergy. Henry IV. of Germany was a violent man, and a furious struggle took place. The Emperor took it on himself to depose the Pope, the Pope at the same time sentenced the Emperor to abstain from the exercise of his power, and his subject; elected another prince in his stead.

At one time Gregory compelled Henry to come barefooted to implore absolution; at another, Henry besieged Rome, and Gregory was only rescued from him by the Normans of Apulia, and was obliged to leave Rome, and retire under their protection to Apulia, where he died in 1085, after having devoted his whole life to the fulfilment of his great project of making the powers of this world visibly submit themselves to the dominion of the Church.

The strife did not end with Gregory’s death. Henry IV. was indeed dethroned by his wicked son, but no sooner did this very son, Henry V., come to the crown, than he struggled with the Pope as fiercely as his father had done.
