Words spoken by the Cardinal Archbishop of Westminster at the Solemn Requiem at the Oratory, South Kensington, 20th August 1890.

"We have lost our greatest witness for the Faith, and we are all poorer and lower by the loss."

To Cardinal Manning and Pope St. Pius X, we can add Cardinal Merry del Val (Secretary of State under Pope St. Pius X) to the defenders of the orthodoxy of Cardinal Newman:

"Pascendi had in fact been commissioned by a native English-speaking cardinal; indeed, by a consultor to the Index, who actively quoted Newman’s writings and recommended them to others. Far from being a liberal fifth column within the Vatican, this was none other than Pius’ impeccably ultramontane Cardinal Secretary of State, Rafael Merry del Val...It was Merry del Val who commissioned [Fr.] Joseph Lemius, procurator of the Oblates of Mary Immaculate, to draft Pascendi; Merry del Val who took a lead role in enforcing its anti-modernist agenda; and – nota bene – Merry del Val who tirelessly championed Newman’s orthodoxy, using the semi-official L’Osservatore Romano to underline the ‘world of difference between what the Cardinal taught and the Modernism which is condemned in the Encyclical."

I think I place more stock in the endorsement and defenses of St. Pius X, Cardinal Manning, and Cardinal del Val, than in the condemnations of Ladislaus and Cassini.

Cardinal Newman was a total pre-Modernist.  The great Orestes Brownson, a convert, and one of the greatest writers in American history, totally destroyed Newman's liberalism.
