Letter 2088: It is the voice of law and justice that a good-faith contract cannot be rescinded.

It is the voice of justice and of the laws that a contract made in good faith cannot be rescinded. Our brother Helpidius desires to obtain the enforcement of this principle, for after the sale of his estate in Spain the buyer refuses to acknowledge part of the price, although everything was carried out in the customary manner toward the full transfer of the property conveyed to its new owner. This is the substance of his request, which, though supported by my words, is in truth aided by his own merits, so that by that equity for which you are distinguished you may either, by private rebuke, confound the shamelessness of the man who resists, or break his obstinacy by the authority of a public judgment. Farewell.
