American Jewish leaders are to meet with Pope Benedict XVI over a bishop who denies the Holocaust. Rabbi Arthur Schneier is leading a delegation of about 60 people to the Vatican. The rabbi is a Holocaust survivor and was host to the pope at his synagogue in New York in April. Before Thursday's meeting Schneier said he wanted to thank Benedict for his commitment to strong Catholic-Jewish ties. Schneier said the controversy was a temporary setback to relations between the two religions. The Vatican said that Benedict did not know about the views of Bishop Richard Williamson when he agreed to lift his excommunication and that of three other ultraconservative bishops last month.
