Williamson condemns the Jewish religion. He has called Jews the "enemies of Christ" and urges their conversion to Catholicism. He says that Jews and Freemasons have contributed to the "changes and corruption" in the Catholic Church. He has also stated that Jews aim at world dominion and believes "The Protocols of the Elders of Zion" to be authentic. Williamson has denied that he is promoting hatred, identifying the contemporary enemies of the faith as "Jews, Communists and Freemasons". He argues that "Anti-Semitism means many things today, for instance, when one criticizes the Israeli actions in the Gaza Strip. The Church has always understood the definition of anti-Semitism to be the rejection of Jews because of their Jewish roots. This is condemned by the Church."
