Actually the Catholics were very much against Jews, but many of the early church were also. Martin Luther said horrible things against the Jews. So I do see why there are bad feelings where Christians are concerned when it comes to the Jews.
So many people are ignorant of just how horrible Martin Luther was in regard to the Jews. Most don't want to even consider the VERY bad side of him because of the truly heroic effort to preach Salvation by Grace through Faith alone.
Here are his thoughts on the Jews, which echoed even to Adolph Hitler, as he partially used Luther as justification of Jewish persecution.
VERY small wonder Jews are skeptical of Christians:
The Jews, he alleges, look for biblical truth “under the sow’s tail,” that is, their interpretation of the Bible comes from looking in a pig’s anus. . . . They defame Christian belief, “impelled by the Devil, to fall into this like filthy sows fall into the trough.” If they see a Jew, Christians should “throw sow dung at him . . . and chase him away.” Luther calls for the secular authorities to burn down all the synagogues and schools, and “what won’t burn should be covered over with earth, so that not a stone or piece of slag of it should be seen for all eternity.” The Jews’ houses should be destroyed and they should be put under one roof, like the gypsies. The Talmud and prayer books should be destroyed and Jewish teachers banned. They should be prevented from using the roads, usury banned, and the Jews forced to undertake physical labor instead. Assets from moneylending should be confiscated and used to support Jews who converted. This was a program of complete cultural eradication. And Luther meant it. . . .
Luther’s anti-Semitism then reached a crescendo of physical revulsion. He imagined Jews kissing and praying to the Devil’s excrement: “the Devil has emptied . . . his stomach again and again, that is a true relic, which the Jews, and those who want to be a Jew, kiss, eat, drink, and worship.” In a kind of inverted baptismal exorcism, the Devil fills the mouth, nose, and ears of the Jews with filth: “He stuffs and squirts them so full, that it overflows and swims out of every place, pure Devil’s filth, yes, it tastes so good to their hearts, and they guzzle it like sows.” Whipping himself into a frenzy, Luther invokes Judas, the ultimate Jew: “When Judas hanged himself, so that his guts ripped, and as happens to those who are hanged, his bladder burst, then the Jews had their golden cans and silver bowls ready, to catch the Judas piss (as one calls it) with the other relics, and afterwards together they ate the shit and drank, from which they got such sharp sight that they are able to see such complex glosses in Scripture.”
This summary provides only a sampling of Luther’s hate-filled vitriol. Multiple passages in his 1543 writings against the Jews are just as abhorrent.
