That writer could not be more wrong about Newman. And I would advise people to actually read Newman to find out what he really says rather than pass on the paranoid conspiracy theories of some traditionalist theologians regarding any thinker who does anything other than relate what commentators have said about Thomistic texts.
Newman’s education was classical and patristic, he was hardly exposed to St. Thomas. He called Aristotle the “the oracle of nature and of truth” and went on to say “In many subject-matters, to think correctly, is to think like Aristotle.”
The Idea of a University, I, V, 5] He called Thomas the “champion of revealed truth” (II, V, 2) and one of the truly great intellects of mankind (I,VI, 5).
Regarding assent:
To her [the Church] is committed the care and the interpretation of the revelation. The word of the Church is the word of the revelation. That the Church is the infallible oracle of truth is the fundamental dogma of the Catholic religion; and “I believe what the Church proposes to be believed” is an act of
real assent, including all particular assents, notional and real.
The Grammar of Assent, 5, 3]
I would read
this whole section of the Grammar.
This is so because Newman saw dogmas as expressing revealed facts; and facts call forth real assent.
Catholic dogmas are, after all, but symbols of a
divine fact, which, far from being compassed by those very propositions, would not be exhausted, nor fathomed by a thousand. . . . Such sentences as “the Word of God” . . . or “the Word was made flesh”. . . are not a mere letter which we may handle by the rules of art at our own will, but august tokens of most simple, ineffable, adorable
facts, embraced, enshrined according to its measure in the believing mind.
[John Henry Newman, *Oxford University Sermons 15:23; 24 (3)]
Newan sees dogma at the heart of Catholicism.
The principle of
dogma, that is, supernatural truths irrevocably committed to human language, imperfect because it is human, but definitive and necessary because given from above.

“Reason, thus considered, is subservient to faith, as handling, examining, explaining, recording, cataloguing, defending the truths which faith, not reason, has gained for us, as providing an intellectual expression of supernatural facts, eliciting what is implicit, comparing measuring, connecting each with each, and forming one and all into a theological system.”
Essay on the Development of Christian Dogma, II, 7, 3, 1]
He explicitly and vehemently rejects liberalism and rationalism:
“Now by Liberalism I mean false liberty of thought, or the exercise of thought upon matters, in which, from the constitution of the human mind, thought cannot be brought to any successful issue, and therefore is out of place. Among such matters are first principles of any kind; and of these the most sacred and momentous are especially to be reckoned the truths of Revelation. Liberalism then is the mistake of subjecting to human judgment those revealed doctrines which are in their nature beyond an independent of it, and of claiming to determine on intrinsic grounds the truth and value of propositions which rest for their reception simply on the external authority of the Divine Word.”
The third example he gives of Liberalism is “No theological doctrine is anything more than an opinion which happens to be held by bodies of men. Therefore, e.g., no creed, as such, is necessary for salvation.”
Apologia Pro Vita Sua, (NY: Longmans, Green, and Co., 1900), p. 288, Note “A”, Liberalism.]
“Rationalism is a certain abuse of reason; that is, a use of it for purposes for which it was never intended, and is unfitted. To rationalize in matters of revelation is to make our reason the standard and measure of the doctrines revealed; to stipulate that those doctrines should be such as to carry with them their own justification; to reject them if they come into collision with our existing opinions or habits of thought, or are with difficulty harmonized with our existing stock of knowledge. And thus the rationalistic spirit is the antagonist of Faith; for faith is, in its very nature, the acceptance of what our reason cannot reach simply and absolutely upon testimony.”
