BERLIN — German Chancellor Angela Merkel called on Pope Benedict XVI to make a "very clear" rejection of Holocaust denials after the Vatican's rehabilitation of a former bishop who questioned whether 6 million Jews were gassed by the Nazis.
Merkel's rare and public demand came amid increasing outrage among Germany's Roman Catholic leaders over the German-born pope's decision.
Merkel said she "does not believe" there has been adequate clarification of the Vatican's position on the Holocaust amid the controversy over the lifting of the excommunication of British-born Richard Williamson.
Benedict last week expressed "full and indisputable solidarity" with Jews and warned against any denial of the horror of the Holocaust, but several leading German bishops have decried the decision and called for the rehabilitation to be revoked.
The issue is particularly sensitive in Germany, where denial of the Holocaust is a crime and Roman Catholic leaders have worked hard to restore relations with the Jewish community.
"I do not believe that sufficient clarification has been made," Merkel said.
The Vatican moved quickly to counter Merkel's suggestion.
"The pope's thinking on the subject of the Holocaust has been expressed very clearly," said Vatican spokesman Rev. Federico Lombardi.
He cited the pope's visit to a synagogue during his first visit to Germany as pope in 2005, a visit to Auschwitz in 2006 and his remarks during last week's general audience.
"I hope that the memory of the Shoah leads humanity to reflect on the unpredictable power of evil when it conquers the heart of men," Lombardi quoted the pope as saying. "May the Shoah be a warning for all against oblivion, against denial or reductionism."
Lombardi said that during the audience "the pope himself clearly explained the purpose of lifting the excommunication, which has nothing to do with any legitimization of positions denying the Holocaust, which were clearly condemned" by Benedict.
Williamson was consecrated by the late ultraconservative Archbishop Marcel Lefebvre without papal consent, leading to his excommunication. The Holy See has said that removing the excommunication did not imply the Vatican shared his views.
Merkel's stand was out of the ordinary, said Elan Steinberg, vice president of the New York-based American Gathering of Holocaust Survivors and their Descendants.
"When the German Chancellor admonishes a German-born Pope it is an extraordinary message," Steinberg said in an e-mail to The Associated Press.
"Together with the expressions of outrage emanating from German and Austrian bishops, these developments have ironically strengthened relations between Germany and the world Jewish community."
Cardinal Francis George, president of the U.S. Conference of Catholic Bishops, made his first comment on the controversy Tuesday, calling Williamson's Holocaust denial "deeply offensive and utterly false." He affirmed the U.S. bishops' opposition to anti-Semitism.
Williamson, in an interview broadcast last month on Swedish state TV, said that historical evidence "is hugely against 6 million Jews having been deliberately gassed in gas chambers as a deliberate policy of Adolf Hitler."
He cited what he called the estimates of the "most serious" revisionists that "between 200,000 and 300,000 perished in Nazi concentration camps, but not one of them by gassing in a gas chamber."
As a young man in Germany, Benedict, then called Joseph Ratzinger, served briefly in the Hitler Youth corps as required. In his autobiography, he said he tried to avoid Hitler Youth meetings.
