Thomas Aquinas on the Formal Sufficiency of Scripture
Dr. Michael Liccione has responded to my post on the distinction between formal and informal sufficiency of Scripture, and specifically objects to my reading that Thomas Aquinas subscribes to a “formal sufficiency” of Scripture. By a formal sufficiency I had meant that Scripture has an inherent intelligibility that does not derive from some source outside itself. To the contrary, I had stated that a merely material sufficiency would not have an inherent intelligibility, but would rather derive its intelligibility from an outside source. Dr. Liccione specifically quarrels with my reading of Aquinas, and insists to the contrary, that Aquinas affirmed the “material sufficiency” of Scripture
in the sense explained by WW, in no way affirmed the formal sufficiency of Scripture in the sense explained by WW. That is partly why Aquinas, like Newman and even Vatican II after him, most certainly did see a magisterium as necessary for interpreting Scripture reliably.
I find this a startling admission, and shows at least that I have not misunderstood the kind of argument being put forward by current disciples of John Henry Newman. Dr. Liccione’s defense for his interpretation of Aquinas is a quotation from S.T. 2.2.5.3:
Now the formal object of faith is the First Truth, as manifested in Holy Writ and the teaching of the Church, which proceeds from the First Truth. Consequently whoever does not adhere, as to an infallible and Divine rule, to the teaching of the Church, which proceeds from the First Truth manifested in Holy Writ, has not the habit of faith, but holds that which is of faith otherwise than by faith.
Unfortunately, the passage does not mean what Dr. Liccione claims that it means, as one can discern from its immediate context. Thomas is not concerned here with epistemological questions such as Dr. Liccione’s distinction between “opinion” and the infallible teaching of the “magisterium.” Indeed, the authority of the magisterium is not the point of discussion at all. Aquinas mentions the “teaching of the Church,” but he nowhere mentions the pope, for example. To know what he means we have to know which specific teaching of the Church he is talking about, and why he considers it infallible. (more…)
