To show favor to those readers whom it is not right to assist, is rather a mark of wickedness than of piety. For this reason, where any Jew reads books, or studies doctrines, in which the Christian faith is denied, or keeps or conceals such books in his house, he shall either receive a hundred lashes in public, or shall have his head shaved. Let all persons be cautious and beware of having books containing such doctrines in their possession, or of studying the same, or of even meditating upon them. And if, henceforth, anyone should attempt to repeat such an offence, he shall receive a hundred lashes, shall have his head shaved, and shall be condemned to perpetual exile; and because he has committed the offence a second time, he shall also lose his property, which shall be bestowed upon whomever the king may direct. Those shall be liable to a similar penalty, who presume to instruct children in the false doctrines contained in such books; and the teacher himself, when detected in the first transgression, shall receive a hundred lashes, and have his head shaved, and shall bind himself by a written agreement never to teach such doctrines again. If, after this, he should violate his agreement, and attempt to repeat what he had formerly renounced, all his property shall be forfeited to the king, and he himself shall receive a hundred lashes, shall have his head shaved, and be condemned to perpetual exile. All children under ten years of age, who are proved to have studied said false doctrines, shall be exempt from the penalties aforesaid. But any child over the age of ten years, who studies or meditates upon such doctrines, shall be liable to the fines and punishments hereinbefore mentioned. =XII. Christian Slaves shall not Serve, or Associate with, Jews.= It truly seems a crime of no small importance to the society of Christians, that the impious Jewish race, always rebellious against the rule of God, should have Christian slaves in their service, and, on the other hand, that an honorable adherent of the Christian religion should be humiliated in the presence of the children of infidels; that thus the body of Christ should appear to do homage to the ministers of Antichrist; and that, through a monstrous regulation, those very persons who are contending, by means of their customs, against our religion, should have the services of slaves attached to our Holy Faith subject to their impiety and errors. For which reason, we decree that henceforth the law promulgated by our glorious predecessor, Sisebutus, of holy memory, shall, in cases of this kind, remain in full force, and we hereby confirm the same except the clause by which the penalty of death is imposed; the said law being the one whereby our predecessors have placed all transgressors of the same under a perpetual curse.
