Sister Rose Thering (August 9, 1920 in Plain, Wisconsin – May 6, 2006 in Racine, Wisconsin) was a Roman Catholic Dominican nun, activist against anti-Semitism, educator and a professor of Catholic-Jewish dialogue at Seton Hall University.

Rose Elizabeth Thering was born in Plain, Wisconsin, the sixth of 11 children in a German-American farm family that prayed together daily. She entered St. Catherine Siena Convent of the Racine Dominican Sisters in Racine, Wisconsin at age 16. She earned a bachelor's from the Dominican College in Racine in 1953, a master's from the College of St. Thomas in St. Paul in 1957 and a doctorate at St. Louis University four years later.

After taking her orders she did her doctorate dissertation at the Jesuit-run Saint Louis University. Her subject was the treatment of Jews in Catholic textbooks. Her findings were shocking. In the film she recalls how she "almost got ill" reading these texts that were being used across the country to educate school children (see [1]).

A dissertation for her 1961 doctorate at St. Louis University that propounded the evidence: textbooks and preachings that abounded in calumnies against Jews and Judaism. Her work was published later in an anthology, “Faith and Prejudice” (by The Paulist Press).

In 1962, when Pope John XXIII convened the ecumenical council known as the Second Vatican Council, Augustin Cardinal Bea used Dr. Thering's study to draft portions of the 1965 Vatican document “Nostra Aetate” (“In Our Age”), which reversed church policy and declared of Christ's death that “what happened in his passion cannot be charged against all the Jews, without distinction, then alive, nor against the Jews of today,” and, as for teaching, added, “The Jews should not be presented as rejected or accursed by God.”

As Dr. Thering recalled later, “They were 15 lines in Latin, but they changed everything.”

In 1974, Dr. Thering presented a menorah to Pope Paul VI at the Vatican. In 1986, she went to Austria to protest the inauguration of President Kurt Waldheim, the former U.N. secretary-general, who had served in a Nazi army unit implicated in the deportation of Jews from Greece during World War II. In 1987, she went to the Soviet Union to protest the government's treatment of Russian Jews.

Following her teaching career she was named Emerita Professor at Seton Hall University. As a member of a commission appointed by Gov. Thomas Kean, she helped write a 1994 law mandating the teaching of the Holocaust and genocide in all elementary and high schools in New Jersey. At Seton Hall, where she joined the faculty in 1968, she established workshops on Judaism for church leaders and teachers, and led student groups on 54 tours of Israel (see [2]).  Late in life Dr. Thering remained an active and vigorous opponent of anti-Semitism.[3]A film about her activism Sister Rose's Passion (directed by Oren Jacoby) was made in 2004. It was nominated for an Academy Award.

She died, aged 85, from kidney failure in 2006.
