Thomas Merton, Journals, vol. 5 (1963-1965), p. 295:
In the refectory the other day articles on the Council [Vatican II, 1962-1965] were being read and a lot was said about St. Thomas [Aquinas] -- he is no longer on an official pedestal -- he is no longer the one to be followed as chief authority in seminary teaching. This is the best thing that could happen to St. Thomas and to Catholic Truth, if we consider that he himself would never have consented to be the kind of authority the textbooks have made of him (and as a matter of fact the Church did not really constitute him an authority -- but rather a model.)
It would be interesting to hear Ed Feser's take on this.
