If you were REALLY friends of a Jew you would want them to convert from the vomit of Judaism to the one, true Church that leads to Salvation.
Here is what the Church Magisterium historically taught about being "friends" with Jews:
The Ecumenical Council of Florence, in union with Pope Eugene IV, dogmatically declared: “It firmly believes, professes and preaches that all those who are outside the catholic church, not only pagans but also JEWS or heretics and schismatics, cannot share in eternal life and will go into the everlasting fire which was prepared for the devil and his angels, unless they are joined to the catholic church before the end of their lives”
Moreover, the Council of Florence dogmatically declared: “It firmly believes, professes and teaches that the legal prescriptions of the old Testament or the Mosaic law, which are divided into ceremonies, holy sacrifices and sacraments, because they were instituted to signify something in the future, although they were adequate for the divine cult of that age, once our lord Jesus Christ who was signified by them had come, came to an end and the sacraments of the new Testament had their beginning. Whoever, after the passion, places his hope in the legal prescriptions and submits himself to them as necessary for salvation and as if faith in Christ without them could not save, sins mortally. It does not deny that from Christ's passion until the promulgation of the gospel they could have been retained, provided they were in no way believed to be necessary for salvation. But it asserts that after the promulgation of the gospel they cannot be observed without loss of eternal salvation. Therefore it denounces all who after that time observe circumcision, the sabbath and other legal prescriptions as strangers to the faith of Christ and unable to share in eternal salvation, unless they recoil at some time from these errors. Therefore it strictly orders all who glory in the name of Christian, not to practise circumcision either before or after baptism, since whether or not they place their hope in it, it cannot possibly be observed without loss of eternal salvation.”
The Council of Florence renewed canons of previous Councils, saying: “Furthermore, renewing the sacred canons, we command both diocesan bishops and secular powers to prohibit in every way Jews and other infidels from having Christians, male or female, in their households and service, or as nurses of their children; and Christians from joining with them in festivities, marriages, banquets or baths, or in much conversation, and from taking them as doctors or agents of marriages or officially appointed mediators of other contracts. They should not be given other public offices, or admitted to any academic degrees, or allowed to have on lease lands or other ecclesiastical rents. They are to be forbidden to buy ecclesiastical books, chalices, crosses and other ornaments of churches under pain of the loss of the object, or to accept them in pledge under pain of the loss of the money that they lent. They are to be compelled, under severe penalties, to wear some garment whereby they can be clearly distinguished from Christians. In order to prevent too much intercourse, they should be made to dwell in areas, in the cities and towns, which are apart from the dwellings of Christians and as far distant as possible from churches. On Sundays and other solemn festivals they should not dare to have their shops open or to work in public.”
In 1442, Pope Eugene IV, in Dundum Ad Nostram Audientiam, decreed: “We decree and order that from now on, and for all time, Christians shall not eat or drink with Jews; nor admit them to feasts, nor cohabit with them, nor bathe with them. Christians shall not allow Jews to hold civil honors over Christians, or to exercise public offices in the State. Jews cannot be merchants, Tax Collectors, or agents in the buying and selling of the produce and goods of Christians, nor their Procurators, Computers or Lawyers in matrimonial matters, nor Obstetricians; nor can they have association or partnership with Christians. No Christian can leave or bequeath anything in his last Will and Testament to Jews or their congregations. Jews are prohibited from erecting new synagogues. They are obliged to pay annually a tenth part of their goods and holdings. Against them Christians can testify, but the testimony of Jews against Christians in no case is of any value. All and every single Jew, of whatever sex and age, must everywhere wear the distinct dress and known marks by which they can be evidently distinguished from Christians. They cannot live among Christians, but in a certain street, separated and segregated from Christians, and outside which they cannot under any pretext have houses”
On July 14th, 1555, Pope Paul IV published the Papal Bull, Cum Nimis Absurdum, saying: ”Since it is completely senseless and inappropriate to be in a situation where Christian piety allows the Jews (whose guilt—all of their own doing—has condemned them to eternal slavery) access to our society and even to live among us; indeed, they are without gratitude to Christians, as, instead of thanks for gracious treatment, they return invective, and among themselves, instead of the slavery, which they deserve, they manage to claim superiority: we, who recently learned that these very Jews have insolently invaded Rome from a number of the Papal States, territories and domains, to the extent that not only have they mingled with Christians (even when close to their churches) and wearing no identifying garments, but to dwell in homes, indeed, even in the more noble [dwellings] of the states, territories and domains in which they lingered, conducting business from their houses and in the streets and dealing in real estate; they even have nurses and housemaids and other Christians as hired servants. And they would dare to perpetrate a wide variety of other dishonorable things, contemptuous of the [very] name Christian. Considering that the Church of Rome tolerates these very Jews (evidence of the true Christian faith) and to this end [we declare]: that they, won over by the piety and kindness of the See, should at long last recognize their erroneous ways, and should lose no time in seeing the true light of the catholic faith, and thus to agree that while they persist in their errors, realizing that they are slaves because of their deeds, whereas Christians have been freed through our Lord God Jesus Christ, and that it is unwarranted for it to appear that the sons of free women serve the sons of maids.”
Pope Paul IV then commanded 15 directives:
The Jews were to be segregated into their own ghetto in Rome and wherever else they dwell.
The Jews could only have one synagogue in any of their dwelling places.
The Jews were to wear the Jewish hats and yellow stars in public.
The Jews were forbidden to have Christian nurses, maids, servants, and wet-nurses.
The Jews couldn’t work or have work done on Sundays or Catholic Feast Days.
The Jews couldn’t incriminate Christians nor promulgate false or forged agreements.
The Jews couldn’t play, eat, or fraternize with Christians.
The Jews couldn’t use any language other than Latin or Italian in any legally recognized documents with Christians.
The Jews were limited to the trade of rag-picking, and were not to trade in grain, barley, or any other commodity essential to human welfare.
The Jews who were physicians were not to attend or treat any Christians.
The Jews were not to be addressed as superiors, even by poor Christians.
The Jews had severe restrictions enforced on their loan practices.
The Jews were to adhere to all statutes regarding the primacy of Christians.
Disobeying these directives would be treated as a crime punishable by judicial authority.
The disciplines of this Papal bull overrode any other prior contrary Magisterium disciplines.
