On the chastity of Abbot Serenus.
As we desire to introduce to earnest minds the Abbot Serenus, a man of the greatest holiness and continence, and one who answers like a mirror to his name, whom we admired above all others with peculiar veneration, we think that we only carry out our desire by the attempt to insert his conferences in our book. To this man beyond all other virtues, which shone forth not merely in his actions and manners, but by God's grace in his very look as well, there was granted by a special blessing the gift of continence, so that he never felt himself disturbed even by natural incitements even in sleep. And how it was that by the assistance of God's grace he attained such wondrous purity of the flesh, as it seems beyond the conditions of human nature, I think that I ought first of all to explain.
