...the Catholic Church has always been accustomed to pray for the Jewish people, who were the depository of divine promises up until the arrival of Jesus Christ, notwithstanding their subsequent blindness, or rather, because of this very blindness. Moved by that charity, the Apostolic See has protected the same people from unjust ill-treatment, and just as it censures all hatred and enmity among people, so it altogether condemns in the highest degree possible hatred against the people once chosen by God, viz., the hatred that now is what is usually meant in common parlance by the term known generally as “anti-Semitism.” - Sacred Congregation of the Holy Office, Decree Cum Supremae, March 25, 1928; approved by Pius XI.
Saint John Paul 2’s prayer at the western wall of the Jerusalem temple: : “God of our fathers, You chose Abraham and his descendants to bring your Name to the nations: we are deeply saddened by the behavior of those who in the course of history have caused these children of yours to suffer, and asking your forgiveness we wish to commit ourselves to genuine brotherhood with the people of the Covenant.”
