Decree issued by the Council of Basel [Switzerland]: “… renewing the sacred canons, we command both diocesan bishops and secular powers to prohibit in every way Jews and other infidels from having Christians, male or female, in their households and service, or as nurses of their children; and Christians from joining with them in festivities, marriages, banquets or baths, or in much conversation, and from taking them as doctors or agents of marriages or officially appointed mediators of other contracts. They should not be given other public offices, or admitted to any academic degrees, or allowed to have on lease lands or other ecclesiastical rents. They are to be forbidden to buy ecclesiastical books, chalices, crosses and other ornaments of churches under pain of the loss of the object, or to accept them in pledge under pain of the loss of the money that they lent. They are to be compelled, under severe penalties, to wear some garment whereby they can be clearly distinguished from Christians. In order to prevent too much intercourse, they should be made to dwell in areas, in the cities and towns, which are apart from the dwellings of Christians and as far distant as possible from churches. On Sundays and other solemn festivals they should not dare to have their shops open or to work in public…Converts should be forbidden, under pain of severe penalties, to bury the dead according to the Jewish custom or to observe in any way the Sabbath and other solemnities and rites of their old sect…If converts fail to correct themselves after a canonical warning, and as Judaizers are found to have returned to their vomit, let proceedings be taken against them as against perfidious heretics in conformity with the enactments of the sacred canons.”
