Pope Benedict XVI stated that he deplored all forms of antisemitism and that all Catholics must do the same. The Pope expressed his "unquestionable solidarity" with the Jewish people, and stated his hope that "the memory of the Shoah will induce humanity to reflect on the unpredictable power of hate when it conquers the heart of man", and condemned the denial of the Holocaust. Vatican officials stated that they had not been aware of Williamson's views prior to the lifting of the excommunication; as a result, in a July 2009 Vatican reorganisation, the Pope tightened control and supervision over reconciliation efforts with SSPX.
