Papal Bull “Cum In Sacro Generali,” issued by Pope Innocent IV to the Archbishop of Besançon [present-day France]: ”Since, after careful deliberation, it has been decreed in the General Council that the Jews shall by their clothes be distinguishable from the Christians, lest Christians and Jews be able to have sinful intercourse with women of the other faith, we, therefore, through Apostolic Letters, order Your Fraternity to compel the Jews of your province and diocese to wear clothes in accordance with the decree of the said Council. After duly warning them, you shall compel them to this by shutting them off from communication with the faithful, appeal denied.”
