Nevertheless, the 12th canon of the First Council of Carthage (345) and the 36th canon of the Council of Aix (789) have declared it to be reprehensible even for laymen to make money by lending at interest. The canonical laws of the Middle Ages absolutely forbade the practice. This prohibition is contained in the Decree of Gratian, q. 3, C. IV, at the beginning, and c. 4, q. 4, C. IV; and in 1. 5, t. 19 of the Decretals, for example in chapters 2, 5, 7, 9, 10, and 13. These chapters order the profit so obtained to be restored; and Alexander III (c. 4, "Super eo", eodem) declares that he has no power to dispense from the obligation. Chapters 1, 2, and 6, eodem, condemns the strategems to which even clerics resorted to evade the law of the general councils, and the Third of the Lateran (1179) and the Second of Lyons (1274) condemn usurers. — Catholic encyclopedia
