Input: 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.
Output:
