Okay, I read it. A good article.
"Strictly speaking, “Baroque theology” refers to the scholastic theology of the seventeenth and eighteenth centuries, but Congar used it as a blanket term for scholasticism as he encountered it in his own time. The old scholasticism didn’t need to be supplemented; it needed to be sidelined, if not eliminated."
This is an odd way to start your post, given that the context actually has the author disagreeing with Congar. Your contextless quote indicates otherwise. These are the preceding sentences that you leave out:
But there was a critical, negative, and potentially destructive edge to the ressourcement program. The rejuvenation of Catholic theology required that the old be swept away. Yves Congar noted at one point in his post–World War II journal that he and Marie-Dominique Chenu agreed “on the necessity of ‘liquidating Baroque theology.’”
Further on, in the author's own voice:
A wider ressourcement brings new resources into the present; it does not return to the past. Today, the “Baroque theology” that attracted the ire of Yves Congar is a “new resource.” We might even profit from a reexamination of the maligned theology manuals. We might learn a thing or two about how to write good (and no doubt quite different) textbooks for today’s seminarians and other beginning students in theology.
And the concluding paragraph in full:
Let me end with one such argument. It cannot be denied that Catholic theology is pursued today with little or no firsthand knowledge of most of what has been written and thought over the last 700 years. My own experience has led me to judge this a loss that has handicapped us. My thinking over the last decade has been enriched and sharpened by my reading of theologians from those neglected centuries—Scotus, Diego Laínez, Báñez, Suárez, Möhler, Scheeben, de la Taille, De Letter, even Ockham (yes, Ockham—his arguments are sharp and illuminating, even if one thinks he is wrong in the end). Saint Paul exhorts us to put on the full armor of God (Eph. 6:11). As theologians, we need all the resources the Spirit provides, and among those are the riches that, all too foolishly, have been cast aside.
Overall this is a good and important article, akin to C. S. Lewis' writings against "chronological snobbery."
Edit: Maybe the elephant in the room is intellectual acumen. Theology has been dumbed down in part because students are not as capable, especially with ancient languages. Aquinas is a challenge for most theology students, and he is used because he is one of the easiest theologians to read and understand.
