A few Italian princes, Gisulfo of Salerno, Azzo d'Este, Beatrice and Matilda of Tuscany, were convoked to the council and held seats in it. The measures passed were very explicit and clear. They condemned the simoniacal clergy in every rank, deposing them from their positions and commanding them to withdraw from the ministrations of the altar. The same judgment was passed upon those who lived with wives or concubines. Both classes were put beyond the pale of the Church, and the people were forbidden, on pain of sharing their doom, to receive the sacraments from them, or to yield them obedience. Nothing more thorough and far-reaching could be. Hitherto the Popes had proceeded by courts of investigation, by examination of individuals, in which the alternative of repentance and renunciation was always open to the prelate who had perhaps inadvertently fallen into these crimes. But such gentle dealings had been but very partially successful. Here and there an archbishop or great abbot had been convicted by his peers, and made to descend from his high estate—here and there a great personage had risen in his place and made confession. Some had retired to the cloister, putting all their pomps and glories aside, and made a good end. But as is usual after every religious revival, life had risen up again and gone upon its usual course, and the bishoprics thus vacated had probably been sold to the highest bidder or yielded to the most violent assailant, as if no such reformation had ever been.

The matter had gone too far now for any such occasional alleviations; and Gregory struck at the whole body of proud prelates, lords of secular as well as ecclesiastical greatness, men whose position was as powerful in politics and the affairs of the empire as was that of the princes and margraves who were their kin, and whom they naturally supported—as the others had supported them by money and influence in their rise to power: but who had very little time for the affairs of the Church, and less still for the preservation of peace and the redress of wrong.

The other measures passed at this council were more searching still; they were aimed against the disorders into which the clergy had fallen, and chiefly what was to Gregory and his followers the great criminality, of married priests, who abounded in the Church. In this the lower orders of the clergy were chiefly assailed, for the more important members of the hierarchy did not marry though they might be vicious otherwise. But the rural priests, the little-educated and but little-esteemed clerks who abounded in every town and village, were very generally affected by the vice—if vice it was—of marriage, which was half legal and widely tolerated: and their determination not to abandon it was furious. Meetings of the clergy to oppose this condemnation were held in all quarters, and often ended in riot, the priests declaring that none of the good things of the Church fell to their lot, but that rather than give up their wives, their sole compensation, they would die. This was not likely to make Gregory's proceedings less determined: but it may easily be imagined what a prodigious convulsion such an edict was likely to make in the ecclesiastical world.

It is said by the later historians that the Empress Agnes was made use of, with her attendant bishop and confessor, to carry these decrees to Henry's court: though this does not seem to be sanctioned by the elder authorities, who place the mission of Agnes in the previous year, and reckon it altogether one of peace and conciliation. But Henry still continued in a conciliatory frame of mind. His own affairs were not going well, and he was anxious to retain the Pope's support in the midst of his conflicts with his subjects. Neither do the great dignitaries appear to have made any public protest or resistance: it was the poor priests upon whom individually this edict pressed heavily, who were roused almost to the point of insurrection.

One of the most curious effects of the decree was the spirit roused among the laity thus encouraged to judge and even to refuse the ministrations of an unworthy priest. Not only was their immediate conduct affected to acts of spiritual insubordination, but a fundamental change seems to have taken place in their conception of the priest's character. No doubt Gregory's legislation must have originated that determined though illogical opposition to a married priesthood, and disgust with the idea, which has had so singular a sway in Catholic countries ever since, and which would at the present moment we believe make any change in the celibate character of the priesthood impossible even were all other difficulties overcome. We are not aware that it had existed in any force before. The thing had been almost too common for remark: and there seems to have been no fierce opposition to the principle. It arose now gradually yet with a force beyond control: there were many cases of laymen baptizing their children themselves, rather then give them into the hands of a polluted priest—until there arose almost a risk of general indifference to this sacrament because of the rising conviction that the hands which administered it were unworthy: and other religious observances were neglected in the same way, an effect which must have been the reverse of anything intended by the Pope. To this hour in all Catholic countries an inexpressible disgust with the thought, mingles even with the theory that perhaps society might be improved were the priest a married man, and so far forced to content himself with the affairs of his own house. Probably it was Gregory's strong denunciation, and his charge to the people not to reverence, not to obey men so soiled: as well as the conviction long cultivated by the Church, and by this time become a dogma, that the ascetic life was in all cases the holiest—which originated this powerful general sentiment, more potent in deciding the fact of a celibate clergy than all the ecclesiastical decrees in the world.

In the second Lateran Council held in the next year, at the beginning of Lent, along with the reiteration of the laws in respect to simony and the priesthood, a solemn decree against lay investiture was passed by the Church. This law transferred the struggle to a higher ground. It was no longer bishops and prelates of all classes, no longer simple priests, but the greatest sovereigns, all of whom had as a matter of course given ecclesiastical benefices as they gave feudals fiefs, who were now involved. The law was as follows:

"Whosoever shall receive from the hands of a layman a bishopric, or an abbey, shall not be counted among the bishops and abbots, nor share their privileges. We interdict him from entrance into the Church and from the grace of St. Peter until he shall have resigned the dignity thus acquired by ambition and disobedience, which are equal to idolatry. Also, if any emperor, duke, marquis, count, or other secular authority shall presume to give investiture of a bishopric or other dignity of the Church, let him understand that the same penalty shall be exacted from him."

The position of affairs between Pope and Emperor was thus fundamentally altered. The father of Henry, a much more faithful son of the Church, had almost without opposition made Popes by his own will where now his son was interdicted from appointing a single bishop. The evil was great enough perhaps for this great remedy, and Gregory, who had gone so far, was restrained now by no prudent precautions from proceeding to the utmost length possible. The day of prudence was over; he had entered upon a path in which there was no drawing back. That it was not done lightly or without profound and painful thought, and a deep sense of danger and impending trouble, is apparent from the following letter in which the Pope unbosoms himself to the head of his former convent, the great Hugo of Cluny, his own warm friend, and at the same time Henry's tutor and constant defender.

"I am overwhelmed (he writes) with great sorrow and trouble. Wherever I look, south, north, or west, I see not a single bishop whose promotion and conduct are legal, and who governs the Christian people for the love of Christ, and not by temporal ambition. As for secular princes, there is not one who prefers the glory of God to his own, or justice to interest. Those among whom I live—the Romans, the Lombards, the Normans—are, as I tell them to their faces, worse than Jews and Pagans. And when I return within myself, I am so overwhelmed by the weight of life that I feel no longer hope in anything but the mercy of Christ."

Notwithstanding the supreme importance of this question, and Gregory's deep sense of the tremendous character of the struggle on which he had thus engaged, matters of public morality in other ways were not sacrificed to these great proceedings for the honour of the Church. He not only himself assumed, but pressed upon all spiritual authorities under him, the duty and need of prompt interference in the cause of justice and public honesty. The letters which follow were called forth by a remarkable breach of these laws of honesty and the protection due to strangers and travellers which are fundamental rules of society. This was the spoliation of certain merchants robbed in their passage through France, and from whom the Pope accuses the young King Philip I. to have taken, "like a brigand, an immense sum of money." Gregory addresses himself to the bishops of France in warning and entreaty as follows:
