In the aftermath of the 1946 Kielce pogrom , Wyszyński was approached by a Jewish delegation seeking his aid . Wyszyński stated that the popular hatred of Jews was caused by Jewish support for Communism ( there was widespread perception in Poland after 1945 that Jews were supportive of the newly installed Communist regime ; see '' Żydokomuna '' ) , which had also been the reason why " the Germans murdered the Jewish nation " . On 12 January 1953 , Wyszyński was elevated to the rank of cardinal priest by Pope Pius XII , but it was not until 1957 that he was designated Cardinal-Priest of Santa Maria in Trastevere
