In all this controversy, it is instructive to observe how Damiani shows himself to be the pure model of monkish asceticism, untainted with any practical wisdom and unwarped by any earthly considerations. When Hildebrand struggled for sacerdotal celibacy, the shrewdness of the serpent guided the innocence of the dove, and he fought for what he knew would prove a weapon of tremendous power in securing for the church the theocracy which was his pure ideal of human institutions. Not a thought of the worldly advantages consequent upon the reform appears to have crossed the mind of Damiani. To him it was simply a matter of conscience that the ministers of Christ should be adorned with the austere purity through which alone lay the path to salvation. Accordingly the arguments which he employs in his endless disputations carefully avoid the practical reasons which were the principal motive for enforcing celibacy. His main reliance is on the assumption that, as Christ was born of a virgin, so he should be served and the Eucharist be handled only by virgins; and his subsidiary logic consists of mystical interpretations of passages in the Jewish history of the Old Testament. Phineas, of course, affords a favorite and oft-repeated argument and illustration. Allusions to Ahimelech can also be understood, but the reasoning based upon the tower of Sichem, the linen girdle of Jeremiah, and the catastrophe of Cain and Abel is convincing only as to the unworldliness of the recluse of Avellana.
