I want to know the answer to the following question:
Who was the teacher who committed the act  ?
All the background I'm provided with is that "[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.". Is that enough to answer the question?
