"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."
