Papal bull, issued by Pope Gregory IX to the clergy of France [Present-day France]: “[B]y means of the secular powers you shall cause the Jews to be forced to remit their usury, and until they do so remit it, they shall be denied communion with the faithful. Moreover, if any of the crusaders cannot at the present time repay their debts to the Jews, you shall see to it that the secular judges provide for them such a beneficial moratorium, that from the time of their departure until their death or return will be known for certain, they shall not incur the burden of usury. You shall, moreover, force the Jews to reckon into the principal the income from the pledge, which may accrue in the meantime, after necessary expenses have been deducted […].”
