St. Bernardino of Siena, treatise on contracts and usury (Tractatus de contractis et usuris), manuscript, 15th century
Magna Carta commands, "If any one has taken anything, whether much or little, by way of loan from Jews, and if he dies before that debt is paid, the debt shall not carry usury so long as the heir is under age, from whomsoever he may hold. And if that debt falls into our hands, we will take only the principal contained in the note."
Vix pervenit is an encyclical, promulgated by Pope Benedict XIV on November 1, 1745, which condemned the practice of charging interest on loans as usury. Because the encyclical was addressed to the bishops of Italy, it is generally not considered ex cathedra. The Holy Office applied the encyclical to the whole of the Roman Catholic Church on July 29, 1836, during the reign of Pope Gregory XVI.
