For his efforts to protect Romanian Jews, Cassulo was accorded the title of "Righteous among the nations by Yad Vashem, Israel's Holocaust memorial. In 1944, the Chief Rabbi of Bucharest praised the work of Cassulo on behalf of Romania's Jews: "the generous assistance of the Holy See… was decisive and salutary. It is not easy for us to find the right words to express the warmth and consolation we experienced because of the concern of the supreme Pontiff, who offered a large sum to relieve the sufferings of deported Jews — sufferings which had been pointed out to him by you after your visit to Transnistria. The Jews of Romania will never forget these facts of historic importance." Cassulo is recognized as Righteous among the Nations by Israel's Yad Vashem memorial.
