"The church has experienced times of brilliance, like that of Thomas Aquinas. But the church has lived also times of decline in its ability to think. For example, we must not confuse the genius of Thomas Aquinas with the age of decadent Thomist commentaries. Unfortunately, I studied philosophy from textbooks that came from decadent or largely bankrupt Thomism. In thinking of the human being, therefore, the church should strive for genius and not for decadence."
Ouch! Even I, Scotist though I be, have spent many happy hours poring over Thomist manuals. I can only dream of such an education.
We might ask, why were they decadent? It is contrasted with "thinking of the human being", which perhaps means restricting ones' theologizing and philosophizing to human affairs and human nature. so no transcendental metaphysics, no seven-fold division of distinction? I'm not really sure. Of course, who would disagree that the church should strive for genius and not decadence?
Maybe this is the best response.
