I suggest that you read Thy Brother's Blood: The Roots of Christian Anti-Semitism by Malcolm Hay (a Catholic priest BTW). He documents the history of anti-Jewish persecution by the Church up until the Holocaust. Even though the Church today has repented of its past, you can't claim it never happened.
Many of the pogroms and persecutions were instigated by Jewish "converts" to Christianity, who converted not out of a sincere salvation, but for revenge motives against their own community.
The 13th-century decree in France confiscating all copies of the Talmud for "anti-Christian" content was inspired by a book-burning conducted by the Jewish communities themselves, destroying the books of Maimonides.
In my last post I acknowledged that the Church mistreated Jews throughout the Middle Ages.
But the Church never authorized, orchestrated or endorsed any pogrom or slaughter of any Jewish community.
