An overview of the Traditional Catholic view of the Jews is never out of order:
The Jews are enemies of God and foes of our holy religion.
~ Padre Pio
The ѕуηαgσgυє is a godless house, a collection of wickedness, and God Himself has damned it.
~ St. Ambrose (PAC, p.642)
Jews are slayers of the Lord, murderers of the prophets, enemies and haters of God, adversaries of grace, enemies of their fathers' faith, advocates of the devil, a brood of vipers, slanderers, scoffers, men of darkened minds, the leaven of Pharisees, a congregation of demons, sinners, wicked men, haters of goodness!
~ St. Gregory of Nyssa
If someone should kill the beloved son of a man, and then stretch forth their hands still stained with blood to the afflicted father, asking for fellowship, would not the blood of his son, visible on the hand of his murderer, provoke him to just anger instead? And such are the prayers of the Jews, for when they stretch forth their hands in prayer, they only remind God-the-Father of their sin against His Son.
And at every stretching-forth of their hands, they only make it obvious that they are stained with the blood of Christ. For they who persevere in their blindness inherit the blood-guilt of their fathers; for they cried out: "His blood be upon us, and upon our children" (Matthew xxvii.25).
~ St. Basil the Great
How dare Christians have the slightest intercourse with Jews, those most miserable of all men. They are lustful, rapacious, greedy, perfidious bandits -- pests of the universe! Indeed, an entire day would not suffice to tell of all their rapine, their avarice, their deception of the poor, their thievery, and their huckstering.
Are they not inveterate murderers, destroyers, men possessed by the devil? Jews are impure and impious, and their ѕуηαgσgυє is a house of prostitution, a lair of beasts, a place of shame and ridicule, the domicile of the devil, as is also the soul of the Jew.
As a matter of fact, Jews worship the devil: their rites are criminal and unchaste; their religion a disease; their ѕуηαgσgυє an assembly of crooks, a den of thieves, a cavern of devils, an abyss of perdition! Why are Jews degenerate? Because of their hateful assassination of Christ. This supreme crime lies at the root of their degradation and woes. The rejection and dispersion of the Jews was the work of God, not of emperors. It was done by the wrath of God and because of His absolute abandonment of the Jews.
Thus, the Jew will live under the yoke of slavery without end.
God hates the Jews, and on Judgment Day He will say to those who sympathize with them., "Depart from Me, for you have had intercourse with My murderers!" Flee, then, from their assemblies, fly from their houses, and, far from venerating the ѕуηαgσgυє, hold it in hatred and aversion.
~ St. John Chrysostom
It is known that the Jєωιѕн people are polluted with wickedness, blasphemy, and the shedding of the blood of Jesus Christ so that their wickedness has no limit.
~ St. Felix of Toledo ("On the Condemnation of the Jews," Council XVII of Toledo, Spain, Canon No. 8; PAC, p.376).
There are innumerable judgments of the ancient Fathers concerning the falsehood of the Jews ... According to the prophetic forecast concerning their stiffneckedness, theirs is the sin of Judas who, in their blindness and stiffneckedness, are harder than a stone.
~ Council of Toledo XVI, Canon no.1 "In the Face of Jєωιѕн Falsehood," PAC, p.371).
O Jєωιѕн hearts, harder than rocks!
~ St. Ambrose
Do not add to your sins by saying that the Covenant is both theirs and ours. Yes, it is ours, but they lost it forever. Assuredly, God gave the Covenant to the Jews, but because of their sins they were not worthy to receive it. Moses received the Testament, but the Jews were not worthy.
~ St. Barnabas
Jews are cursed and covered with malediction as by a cloak. The curse has penetrated them like water in their bowels and oil in their bones. They are cursed in the city and cursed in the country, cursed in their coming in and cursed in their going out. Cursed are the fruits of their loins, of their lands, of their flocks; cursed are their cellars, their granaries, their shops, their food, the very crumbs off their tables!
~ St. Agobard
I knew in my faith that the Jews were accursed and condemned without end, except those who were converted.
~ Bl. Juliana of Norwich
One who dies a Jew will be damned.
~ St. Vincent Ferrer
The Jews, who killed both the Lord Jesus and the prophets, and have persecuted us, do not please God, and they are adversaries to all men, prohibiting us from speaking to the Gentiles that they may be saved, to fill up their sin always: for the wrath of God has come upon them to the end.
~ St. Paul - I Thessalonians ii.14-16
It would be licit, according to custom, to hold the Jews in perpetual servitude because of their crime.
~ St. Thomas Aquinas
Since His spouse, the ѕуηαgσgυє, refused to receive Him, Christ answered: "This is a harlot!" And He gave her a bill of divorce, as we read in Isaias (50:1): "Thus says the Lord: Behold, you are sold for your iniquities; and for your evil deeds have I put your mother away. Because I came and there was not a man; I called and there was no one who would hear." And so the Jews, the sons of the harlot, were repudiated.
~ St. Vincent Ferrer
Go, so that cured by Christian faith, you may not die in Jєωιѕн unfaith, but may live forever with Jesus Christ Our Lord.
~ St. Peter Chrysologus
The faithlessness of the ѕуηαgσgυє is an insult to the Savior. Therefore, He chose the barque of Peter and deserted the boat of Moses; that is, He rejected the faithless ѕуηαgσgυє and adopted the believing Church ... Of these two ships, one is left at the shore, idle and empty; the other, loaded filled, is launched into the deep. For the ѕуηαgσgυє is left idle on the beach. Because of its own fault, it has lost Christ along with the warnings of the prophets. But the freighted Church is taken out into the deep, because it received the Lord together with the teaching of the Apostles.
The ѕуηαgσgυє, I say, remains on the land, held fast as it were to earthly things. The Church is called forth to the deep, as though to search into the profound mysteries of Heaven.
~ St. Ambrose
The Jews knew that Christ was the son of David. And even now they hope for His Coming. It is hidden from them that He has come, but it is hidden because they willed it so. For, not acknowledging Him on the cross, the knowledge of Him reigning in glory should not be theirs ... Why are the Jews hoping for what has already come, and not fearful for what is to come?
For Our Lord Jesus Christ ... referred Himself as "the Stone" (Matthew xxi.44), that whoever stumbles upon it shall be bruised; but upon whom it shall fall, it will grind to powder ... Lying on the ground, it shakes whoever falls over it; coming from on high, it crushes the proud. The Jews have already been shaken by their previous stumble. What awaits them is to be crushed by His Coming.
~ St. Augustine
For, raging against the Gentiles as unclean, Israel became in very truth unclean themselves; while the Gentiles have become clean, the justice of Israel has become like the rag of a menstruous woman.
~ St. Basil the Great
Well should the Jew mourn who, not believing in Christ, has assigned his soul to perdition ...
The Jews have crucified the Son and rejected the Holy Ghost, and their souls are the abode of the devil.
~ St. John Chrysostom
“To judaize, namely to observe Saturday, or other Jєωιѕн ceremonies, is mortal [sin]: because that pertains to the superstition of a false divine cult, according to Cajetan, in his summa. If however one observes Saturday, not for the purposes of a Jєωιѕн rite, but for some other pious reason, such as to venerate the Blessed Virgin Mary, he would not sin mortally.
To converse with Jews is forbidden at Canon Law, in many places in the capitular De Judaeis etc. 28 q. 1 Capitular Nullus, etc and all of them regarding assiduous, and familiar conversation, due to the danger of subversion, and especially in ten cases is it forbidden:
First, to live with them;
Second, to eat with them;
Third, to bathe with them;
Fourth, to call upon them for medical care;
Fifth, to accept their medicine;
Sixth, to feed their children in their houses;
Seven, to serve them, as employees;
Eight, to be their slaves;
Nine, for them to hold public office amongst Christians;
Ten, to eat their azyme [matzo].
To tolerate them in public office is mortal, because this disparages the dignity of the Christian Faith, and for that reason is it forbidden. The same, because this would cause too great a familiarity, and consequently a danger of subversion, as supra. I say the same for the consumption of their azyme. To do all of that is mortal. To eat food with them when one has a choice is never permitted, apart from extreme necessity.”
~ Fra Bartolomeo Fumo, O.P., Inquisitor General for the Duchies of Parma and Piacenza, +1542 A.D. (Citation from the medieval Inquistor’s manual explaining what can and cannot be done vis-à-vis Jews, based on the canonical legislation promulgated by Pope Gregory IX in A.D. 1234, in the capitular “De Judaeis” [Of the Jews].)
When Jews are admitted out of pity into familiar intercourse with Christians, they repay their hosts 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. ~ Pope Innocent III (PAC, p.137).
Pope Alexander II
With troubled heart, We are reminded that many of those converted from the error of Jєωιѕн blindness to the light of the Christian Faith have fallen back into their former falsehood. Proceed with intensity against all who make themselves guilty of this crime, against heretics, and against those who support, protect, and defend them.
~ Pope Nicholas IV (the Bull, "With Troubled Heart," PAC, cf. p.659).
With great sorrow and mortal anxiety, We have heard that the Jews have in a Christian land the same rights as Christians, that Christian men and women live under the same roof with these traitors and defile their souls day and night with blasphemies!
~ Pope Stephen III (Epistle to the Bishop of Norbonne, PAC, cf. p.427).
The hearts of the unbelieving Jews do not even yet by any means acknowledge Christ to be God and, harder than flintstones, they will not be broken by repentance.
~ Pope St. Gregory the Great
The Jews, whom Holy Church tolerates in diverse parts of the world in testimony to Jesus Christ, wish to persevere in their hardness and blindness rather than acknowledge the words of the prophets and the mysteries of the Holy Scriptures, and to come to the knowledge of the Christian faith and salvation.
~ Pope Martin V
Let the Gospel be preached to (Jews) and, if they remain obstinate, let them be expelled.
~ Pope Leo VII
