10. In the fourth place We exhort you not to listen to those who say that today the issue of usury is present in name only, since gain is almost always obtained from money given to another. How false is this opinion and how far removed from the truth! We can easily understand this if we consider that the nature of one contract differs from the nature of another. By the same token, the things which result from these contracts will differ in accordance with the varying nature of the contracts. Truly an obvious difference exists between gain which arises from money legally, and therefore can be upheld in the courts of both civil and canon law, and gain which is illicitly obtained, and must therefore be returned according to the judgments of both courts. Thus, it is clearly invalid to suggest, on the grounds that some gain is usually received from money lent out, that the issue of usury is irrelevant in our times.
