 Pacelli presided as Papal Legate over the International Eucharistic Congress in Buenos Aires , Argentina from 10 – 14 October 1934 , and in Budapest from 25 – 30 May 1938 . At this time , anti @-@ semitic laws were in the process of being formulated in Hungary . Pacelli made reference to the Jews " whose lips curse [ Christ ] and whose hearts reject him even today " . This traditional adversarial relationship with Judaism would be reversed in Nostra aetate issued during the Second Vatican Council . According to Joseph Bottum , Pacelli in 1937 " warned A. W. <unk> , the American consul to Berlin , that Hitler was " an untrustworthy scoundrel and fundamentally wicked person " ; <unk> wrote that Pacelli " did not believe Hitler capable of moderation , and ... fully supported the German bishops in their anti @-@ Nazi stand . " A report written by Pacelli the following year for Roosevelt and filed with Ambassador Joseph Kennedy declared that the Church regarded compromise with the Third Reich as " out of the question " .
