ROME — The Vatican says the Catholic Church must not try to convert Jews to Christianity.

Instead, the Catholic Church must work with Jews and Jewish institutions to further dialogue and mutually understand and fight anti-Semitism, according to the Vatican, which pledged “to do all that is possible with our Jewish friends to repel anti-Semitic tendencies.”

The statements came in a major document released Thursday by the Vatican’s Commission for Religious Relations with the Jews. It was issued to mark the 50th anniversary of Nostra Aetate, a declaration promulgated in 1965 by the Second Vatican Council that opened the door to formal Catholic-Jewish dialogue.

The new document, titled The Gifts and Calling of God are Irrevocable, discussed at length how Christianity is rooted in Judaism. Because of this, it said, the Church is “obliged to view evangelization to Jews, who believe in the one God, in a different manner from that to people of other religions and world views.”

It added, “In concrete terms this means that the Catholic Church neither conducts nor supports any specific institutional mission work directed towards Jews.”

Goals in Jewish-Catholic dialogue, according to the document, include “joint engagement throughout the world for justice, peace, conservation of creation, and reconciliation” in a way that would make the religious contribute toward world peace.

“Religious freedom guaranteed by civil authority is the prerequisite for such dialogue and peace,” it said.

“In Jewish-Christian dialogue the situation of Christian communities in the state of Israel is of great relevance, since there — as nowhere else in the world — a Christian minority faces a Jewish majority,” the document said. “Peace in the Holy Land — lacking and constantly prayed for — plays a major role in dialogue between Jews and Christians.”

Among other goals, the document said, were “jointly combating all manifestations of racial discrimination against Jews and all forms of anti-Semitism, which have certainly not yet been eradicated and re-emerge in different ways in various contexts.” It particularly stressed the need for “unceasing vigilance and sensitivity in the social sphere” and called for tangible joint Jewish-Catholic cooperation, such as in charitable activity to help “the poor, disadvantaged and sick.”
