Passage: John Paul II's visits to his native country in 1979 and 1983 brought support to the budding solidarity movement and encouraged the growing anti-communist fervor there. In 1979, less than a year after becoming pope, John Paul celebrated Mass in Victory Square in Warsaw and ended his sermon with a call to "renew the face" of Poland: Let Thy Spirit descend! Let Thy Spirit descend and renew the face of the land! This land! These words were very meaningful for the Polish citizens who understood them as the incentive for the democratic changes.

Passage: In 1839 Mariano Spada (1796 - 1872), professor of theology at the Roman College of Saint Thomas, published Esame Critico sulla dottrina dell’ Angelico Dottore S. Tommaso di Aquino circa il Peccato originale, relativamente alla Beatissima Vergine Maria [A critical examination of the doctrine of St. Thomas Aquinas, the Angelic Doctor, regarding original sin with respect to the Most Blessed Virgin Mary], in which Aquinas is interpreted not as treating the question of the Immaculate Conception later formulated in the papal bull Ineffabilis Deus but rather the sanctification of the fetus within Mary's womb. Spada furnished an interpretation whereby Pius IX was relieved of the problem of seeming to foster a doctrine not in agreement with the Aquinas' teaching. Pope Pius IX would later appoint Spada Master of the Sacred Palace in 1867.
