Pope Saint Pius V: With full understanding and in exercising of the apostolic powers, we withdraw from the Jews and their rule (and recognize no right or claim) all properties, which the Jews have in their possession in this city Rome or other places of our domain of rule. (*** Nos Super)
Pope Paul IV: It is too absurd and pointless that the Jews, whom their own guilt condemns to slavery, under the pretence that Christian piety suffers and tolerates their coexistence, pay back [with wickedness] the mercy received from Christians. (*** Nimis Absurdum)
Pope Leo VII: Let the Gospel be preached unto them and, if they remain obstinate, let them be expelled.
Pope Adrian I at the Second Ecumenical Council of Nicea: Since certain, erring in the superstitions of the Hebrews, have thought to mock at Christ our God, and feigning to be converted to the religion of Christ do deny him, and in private and secretly keep the Sabbath and observe other Jewish customs, we decree that such persons be not received to communion, nor to prayers, nor into the Church; but let them be openly Hebrew according to their religion, and let them not bring their children to baptism, nor purchase or possess a slave.
Pope Innocent IV: We who long with all our hearts for the salvation of souls, grant you full authority by these present letters to banish the Jews, either in your own person or through the agency of others, especially since, as we have been informed, they do not abide by the regulations drawn up for them by this Holy See. (To the King of France)
Pope Saint Martin I: If anyone shall teach a slave, under pretext of piety, to despise his master and to run away from his service, and not to serve his own master with good-will and all honour, let him be anathema.
Pope Benedict XIV: It is fitting for Jews to serve Christians, but not for Christians to serve Jews. On the contrary, the Jews, as slaves rejected by that Saviour Whose death they wickedly contrived, should recognize themselves in fact and in creed the slaves of those whom the death of Christ has set free, even as it has rendered them bondmen. (Quoting Pope Innocent III, Etsi Judaeos)
Pope Gregory IX: They ought to know the yoke of perpetual enslavement because of their guilt. See to it that the perfidious Jews never in the future become insolent, but that they always suffer publicly the shame of their sin in servile fear. (Epistle to the Hierarchy of Germany)
Pope Alexander III at the Third Lateran Ecumenical Council: We declare that the evidence of Christians is to be accepted against Jews in every case, since Jews employ their own witnesses against Christians - and that those who prefer Jews to Christians in this matter are to lie under anathema, since Jews ought to be slaves to Christians. (Canon 26)

Pope Innocent III: The Jews, by their own guilt, are consigned to perpetual servitude because they crucified the Lord. (To the Archbishops of Sens and Paris)
Pope Innocent IV: And that you [King Saint Louis IX] order both the aforesaid abusive books [The Talmud] condemned by the same doctors and generally all the books with their glosses which were examined and condemned by them to be burned by fire wherever they can be found throughout your entire kingdom, strictly forbidding that Jews henceforth have Christian nurses or servants, that the sons of a free woman may not serve the sons of a bondwoman, but as slaves condemned by the Lord, whose death they wickedly plotted, they at least outwardly recognize themselves as slaves of those whom the death of Christ made free and themselves slaves. So we may commend the zeal of your sincerity in the Lord with due praises. (The Wicked Perfidy of the Jews)
