Pope Benedict XV stated that “the eminent commendations of Thomas Aquinas by the Holy See no longer permit a Catholic to doubt that he was divinely raised up that the Church might have a master whose doctrine should be followed in a special way at all times.”

Pope John Paul II in Fides et Ratio (14 September 1998)

The Church has no philosophy of her own nor does she canonize any one particular philosophy in preference to others.

Of course, JPII did say St Thomas was a model, but one wonders if this was something of a downgrade...

The Popes on St. Thomas

Pope St. Pius V declared him a Doctor of The Church, saying he was “the most brilliant light of the Church,” whose works are “the most certain rule of Christian doctrine by which he enlightened the Apostolic Church in answering conclusively numberless errors … which illumination has often been evident in the past and recently stood forth prominently in the decrees of the Council of Trent.”

Pope Benedict XIII wrote to the Order of Preachers that they should “pursue with energy your Doctor’s works, more brilliant than the sun and written without the shadow of error. These works made the Church illustrious with wonderful erudition, since they march ahead and proceed with unimpeded step, protecting and vindicating by the surest rule of Christian doctrine, the truth of our holy religion.”

Pope St. Pius X said that the chief of Leo’s achievements is his restoration of the doctrine of St. Thomas. For he “restored the Angelic Doctor … as the leader and master of theology, whose divine genius fashioned weapons marvelously suited to protect the truth and destroy the many errors of the times. Indeed those principles of wisdom, useful for all time, which the holy Doctors passed on to us, have been organized by no one more aptly than by Thomas, and no one has explained them more clearly.” Indeed, Pius said, those who depart from the teaching of St. Thomas “seem to effect ultimately their withdrawal from the Church … As we have said, one may not desert Aquinas, especially in philosophy and theology, without great harm; following him is the safest way to the knowledge of divine things. … If the doctrine of any other author or saint has ever been approved at any time by us or our predecessors with singular commendation joined with an invitation and order to propagate and to defend it, it may be easily understood that it was commended only insofar as it agreed with the principles of Aquinas or was in no way opposed to them.” Theology professors “should also take particular care that their students develop a deep affection for the Summa … In this way and no other will theology be restored to its pristine dignity, and the proper order and value will be restored to all sacred studies, and the province of the intellect and reason flower again in a second spring.”

Pope Benedict XV stated that “the eminent commendations of Thomas Aquinas by the Holy See no longer permit a Catholic to doubt that he was divinely raised up that the Church might have a master whose doctrine should be followed in a special way at all times.”
