Papal bull “Non Sine Misterio,” issued by Clement IV to the Archbishop of Seville [Present-day Spain]: “If, however, any creditor does force [the Crusaders] to pay interest, it shall be restored to them, without any option of appeal, and with mandatory stricture [of the creditor]. Jews are to return the interest, under compulsion by a secular power, and until they do so, all of the Christian faithful are ordered, under pain of excommunication, to absolutely refrain from any interaction with these Jews, both in business and otherwise.”
