The holy Fathers spoke justly and they knew to speak firmly when necessary. But they also knew to speak kindly and lovingly, and thus several Jews did convert to Christianity. St. Justin Martyr in his Dialogue with Trypho the Jew is one example, can be read here -

Pope St. Gregory the Great is another example, the Pope who gave us Gregorian Chant and one of only 4 Popes in history to have been acclaimed "the Great, he knew to be both firm where needed and kind when necessary. "For it is necessary to gather those who are at odds with the Christian religion the unity of faith by meekness, by kindness, by admonishing, by persuading, lest these...should be repelled by threats and terrors. They ought, therefore, to come together to hear from you the Word of God in a kindly frame of mind, rather than stricken with dread, result of a harshness that goes beyond due limits." https://en.wikipedia.org/wiki/Pope_Gregory_I_and_Judaism

St. Bernard is another example, there was a fanatical preacher he restrained who was preaching real hatred and saying all Jews were to be arbitrarily killed; St. Bernard controverted this in various ways and St. Bernard was right. Only whenever Jesus and Mary were blasphemed, as in the blasphemous тαℓмυd which was rightly burned, Church authorities were justly severe. Jews and other non-Christians who lived among Christians needed (1) not to blaspheme Jesus, Mary or the Saints; (2) to live at peace with Christians without conspiring violence against them. Those were the conditions. Pope Innocent III outlined this in a letter, "

"As Cain was a wanderer and an outcast, not to be killed by anyone but marked with the sign of fear on his forehead, so the Jews . . . against whom the voice of the blood of Christ cries out . . . although they are not to be killed they must always be dispersed as wanderers upon the face of the earth ... Although Christian piety tolerates the Jews . . . whose own fault commits them to perpetual slavery . . . and allows them to continue with us (even though the Moors will not tolerate them), they must not be allowed to remain ungrateful to us in such a way as to repay us with contumely for favors and contempt for our familiarity. They are admitted to our familiarity only through our mercy" http://www.тαℓмυdunmasked.com/appendix.htm

What later happened in the Jєωιѕн role in promoting Fɾҽҽmαsσɳɾყ and Bolshevism shows how just the Church's restraints were and what would happen without it. St. Maximillian Maria Kolbe was well aware of the ʝʊdɛօ-Masonic plans; nevertheless he said to helpless Jews who were pleading for help, as a contemporary of his related, “When Jews came to me asking for a piece of bread, I asked Father Maximilian if I could give it to them in good conscience, and he answered me, ‘Yes, it is necessary to do this because all men are our brothers” And Pope Pius XII also did the same; that's because Jesus said all will know we are His disciples when we love one another. The тαℓмυdists don't care if millions of innocent people die along with their schemes including even Jews themselves. We are different.

The Catechism of Trent teaches us the duty to love our neighbor extends to all without exception; these Saints knew it and lived it. It also tells us to focus inward, because every mortal sin we commit is like a new killing of Christ in us. This is what the Lord taught also. The modern world is wrong to make light of Deicide as if it were nothing. But we Christians know the solution is for us to become holy, witness to them about the love of Christ, and strive by the grace of God to convert and win them over to His cause. Nothing else.

The Jєωιѕн Temple was destroyed in 70 A.D. because of the sin of the Jєωιѕн people and priests against Christ.

In the end, as St. Bernard and other Fathers and Doctors say, they will be converted to Christ. That probably coincides with the Triumph of the Immaculate Heart of Mary and the conversion of many nations to the Church.
