After the war, Rabbi Herzog dedicated himself to saving Jewish children especially babies and bringing them back from their places of hiding throughout all of Europe, to their families or to Jewish orphanages. Many of these were hidden in Christian monasteries or by Christian families, and refused to return them. In his biography, he tells of the difficulties he had of meeting the Pope who avoided him, but did receive in the end assistance from the Vatican. In later years it was found that Karol Wojtyła, future Pope John Paul II, was the contact who helped the rabbi out. However, defenders of Pope Pius XII have asserted that Herzog had maintained friendly relations with the pontiff during and after the World War II. In 1945, he stated: “The people of Israel will never forget what His Holiness and his illustrious delegates are doing for our unfortunate brothers and sisters in the most tragic hour of our history, which is living proof of Divine Providence in this world.”
