“Diocesan Synod of Mainz/Mayence” held under Bishop of Wolfgang von Grumbach [Present-day Germany; Electorate of Mainz/Mayence]: “In all the cities, towns, and provinces of the diocese of Mainz, and the camp of the nation of the Jews, and the towns of the city, both men and women, are to distinguish themselves clearly through their attire from those of the Christian folk within the next two months after signing and publishing of the statute, […] they [Jews] are to refrain from being in any public positions in which they might have authority over Christians […] or to have Christian servants (slaves) where the latter may have to obey [the Jewish] children which will prevent them from having the same status as the Jews and be compelled to observe their miserable rites and be deprived of the communion of the faithful […] that no Christian man is permitted to allege ignorance of this statute, known to all the rectors of the churches of the city from now on and in the provinces where the Jews reside, under the authority of the said penalty of excommunication by the council, […] and [the rectors are] to publicly announce in their own parishes each Sunday of all four seasons, immediately following mass, the aforementioned statute […].”
