Sanctum Satanum meum. - Peter Damian

Of Pope Gregory VII, in a letter (c. 1070) to Pope Alexander II and Cardinal Archdeacon Hildebrand, Ep. 1. I. ep. 16. T. I. f. 16.

Let that ancient dragon, Cadalus, take note. Let this disturber of the Church, this destroyer of apostolic discipline, this enemy of man’s salvation understand. Let him beware, I say, this root of all sin, this herald of the devil, this apostle of Antichrist. And what else shall I call him? He is the arrow drawn from the quiver of Satan, the rod of the Assyrian, the son Belial, "the son of perdition, who rises in his pride against every god, so called, ever object of men’s worship" (2 Thess. 2:3-4), the whirlpool of lust, the shipwreck of chastity, the disgrace of Christianity, the ignominy of bishops, the progeny of vipers, the stench or the world, the filth of the ages, the shame of the universe. Still more epithets for Cadalus can be added, a list of darksome names: slippery snake, a twisting serpent, the dung of humanity, the latrine of crime, the dregs of vice, the abomination of heaven the expulsion from paradise, the fodder of hell, the stubble of eternal fire.

Any cleric or monk who seduces young men or boys, or who is apprehended in kissing or in any shameful situation, shall be publicly flogged and shall lose his clerical tonsure. Thus shorn, he shall be disgraced by spitting in his face, bound in iron chains, wasted by six months of close confinement, and for three days each week put on barley bread given him toward evening. Following this period, he shall spend a further six months living in a small segregated courtyard in custody of a spiritual elder, kept busy with manual labor and prayer, subjected to vigils and prayers, forced to walk at all times in the company of two spiritual brothers, never again allowed to associate with young men.
