教皇不可謬説
Several figures associated with the College during this period were involved in the defense of the doctrine of Papal infallibility. Dominic Gravina, the most celebrated theologian of his day in Italy, was professor of theology at the College in 1610. Gravina was made master of sacred theology by the General Chapter of the Order at Rome in 1608. He wrote "Vox turturis seu de florenti usque ad nostra tempora ... sacrarum Religionum statu" (1625) in polemic with Robert Bellarmine whose "De gemitu columbae" (1620) criticized the decadence of religious orders. Gravina, wrote concerning Papal infallibility: "To the Pontiff, as one (person) and alone, it was given to be the head;" and again, "The Roman Pontiff for the time beingis one, therefore he alone has infallibility."
