To Gregory, as we must hereafter call him, was generally attributed, by his immediate successors, the honor of introducing, or of enforcing, the absolute chastity of the ministers of the altar. Some chroniclers mention Alexander II. or Leo IX. as participating in the struggle, but to his vigorous management its success was popularly conceded.[533] He earned the tribute thoroughly, for during his whole pontificate it seems to have been ever present to his thoughts, and whatever were his preoccupations in his fearful struggle with the empire, on which he risked the present and the future of the papacy, he always had leisure to attend to the one subject in its minutest details and in the remotest corner of Christendom. Perhaps in this there may have been an unrecognized motive urging him to action. Sprung from so humble an origin, he may have sympathized with the democratic element, which rendered the church the only career open to peasant and plebeian. He may have felt that this was a source of hidden power, as binding the populations more closely to the church, and as enabling it to press into service an unknown amount of fresh and vigorous talent belonging to men who would owe everything to the establishment which had raised them from nothingness, and who would have no relationships to embarrass their devotion. All this would be lost if, by legalizing marriage, the hereditary transmission of benefices inevitably resulting should convert the church into a separate caste of individual proprietors, having only general interests in common, and lazily luxuriating on the proceeds of former popular beneficence. To us, retrospectively philosophizing, it further appears evident that if celibacy were an efficient agent in obtaining for the church the immense temporal power and spiritual authority which it enjoyed, that very power and that authority rendered celibacy a necessity to the welfare of civilization. When even the humblest priest came to be regarded as a superior being, holding the keys of heaven in his hand, and by the machinery of confession, absolution, and excommunication wielding incalculable influence over each member of his flock, it was well for both parties that the ecclesiastic should be free from the ties of family and the vulgar ambition of race. It is easy to see how the churchmen could have selected matrimonial alliances of the most politic and aggrandizing character; and as possession of property and hereditary transmission of benefices would have necessarily followed on the permission to marry, an ecclesiastical caste, combining temporal and spiritual power in the most dangerous excess, would have repeated in Europe the distinctions between the Brahman and Sudra of India. The perpetual admission of self-made men into the hierarchy, which distinguished the church even in times of the most aristocratic feudalism, was for ages the only practical recognition of the equality of man, and was one of the most powerful
