Pope Clement VIII: “The Bible itself says that the Jews are an accursed people.â€
Pope Innocent III: “When Jews are admitted out of pity into familiar intercourse with Christians, they repay their hosts, according to the popular proverb, after the fashion of the rat hidden in the sack, or the snake in the bosom, or of the burning brand in one’s lap.â€

Pope Innocent IV: “The wicked perfidy of the Jews - from whose hearts Our Saviour did not remove the veil because of their enormous crimes but caused them justly to continue in their blindness, commit acts of shame which engender astonishment in those who hear, and terror in those who discover it.†(The Wicked Perfidy of the Jews)

Pope Clement VIII: “All the world suffers from the usury of the Jews, their monopolies and deceit.

Pope Innocent III: “The Lord made Cain a wanderer and a fugitive over the earth, but set a mark upon him, making his head to shake, lest anyone finding him should slay him.

Pope Saint Sylvester I at the First Ecumenical Council of Nicea: “Concerning the prohibition of usury and base gain by the clergy; and concerning the prohibition against conversing or eating with the Jews. No priest shall set money out at interest or take unfair profit or be friendly or sociable with Jews; nor should anyone take food or drink with the Jews; for if this was decreed by the holy apostles, it is incumbent upon the faithful to obey their command; and the synod shall excommunicate any one who does not comply with this order.â€
Pope Eugene IV: “We decree and order that from now on, and for all time, Christians shall not eat or drink with the Jews, nor admit them to feasts, nor cohabit with them, nor bathe with them.

Pope Martin V: “However, we received a short time ago through credible reports knowledge to our great alarm, that various Jews of both sexes in Cafas and other cities, lands and places overseas, which fall under the jurisdiction of Christians, are of obstinate mind and, in order to conceal swindling and wickedness, wear no special sign on their clothing, so that they are not recognisable as Jews. They are not ashamed to give themselves out as Christians before many Christians of both sexes of these cities, districts and places mentioned, who could not in fact identify them, and consequently commit shameful things and crimes.†(Sedes Apostolica)
Pope Eugene IV: “We decree and order that from now on, and for all time […] All and every single Jew, of whatever sex and age, must everywhere wear the distinctive dress and known marks by which they can be evidently distinguished from Christians.â€

Pope Leo VII: “Let the Gospel be preached unto them and, if they remain obstinate, let them be expelled.â€
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.â€
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 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 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.â€
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 Judaeosâ€)

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)
