Read on him more ...

Read the book Faith of Our Fathers.

Uh...I studied this heretic. I have held in my hands letters and docuмents THAT HE WROTE HIMSELF IN INK. I know exactly what and who Gibbons was.

BTW, I have read Faith of Our Fathers, several times during the past 35 years, beginning the first read at age 17. The book is not even a serious theological work. It is a popular and poorly argued apologetics tract filled with Americanist error.

Again, I have read Gibbons. I have studied Gibbons within his historical and political context.

The Americanists in these USA really coasted by because of the vast distance from Europe (Atlantic Ocean), by the politicking in Rome of Americanist and Gibbon's personal secretary Rev. (later Bishop) Denis O'Connell as rector of the North American College, and, above all, by thd scurrilous tract by Abbé Felix Klein entitled Americanism: the Phantom Heresy that white-washed and denied the very existance of the Americanist heresy and makinh Pope Leo XIII look foolish for composing Testem Benevolentiæ.

Americanist was birthed by Paulist Rev. Isaac Hecker, nutured by Cardinal Gibbons, promoted by John Catdinal Ireland, and universalised by Jesuit Rev. John Courtney Murray.

Americanism is the progenitor of Modernism.

As an aside, if you want to know who initiated the flow of sodomites into the American seminaries, take a close look at the East Coast Irish-American prelatial Mafia running the US Church before Vatican II, looking espacially at the time from the 1880s through 1940s. 

Let the reader decide for himself, is this the work of a modernist who is undermining and corrupting Catholic teaching:.

Yes, yes it is.  What's your problem with anyone criticizing Gibbons?  He was a man and not infallible and not above criticism.  I quoted from his proto-Ecuмenical speech about the "separated brethren" (condemned in Mortalium Animos).  Given how much you're shilling for Gibbons, I'm guessing you have some personal attachment.

I agree with your suspicion, Lad. And why is this person posting anonymously?

"OOOOO! Cardinal Gibbons gave the imprimatur to my U.S. Murphy edition Douay-Rheims Bible. He must have been so amazingly traditional!" 🤡

No, I just don't idly attack who can't defend themselves.  Read Faith of Our Fathers. He was a Catholic, no matter what you and Feeney say about him.

I did read Faith of Our Fathers several times. It is a POORLY written, Americanist-inspired popular (non-academic) apologetical tract.

Part of the Americanist heresy is to down-play differences and emphasise similarities between Catholicism and Protestantism as an effort to defend Catholicism and seek converts. This approach was condemned until Unitatis Redintegratio of Vatican II.

This is what Gibbons does in his tract.

He professed the Catholic faith and remained a member of the Church.  That doesn't make him not an Americanist and not a promoter of religious indifferentism and the Ecuмenical mindset, which was pervasive in America long before Vatican II.

You're engaging in a false dichotomy.

Elwin is thoroughly acquainted with Gibbons.  As he mentioned, he's read the originals of some of his writings, and has read the book you posted several times.  I quoted from Gibbons referring to Prots as "separated brethren".

Elwin has asserted things, but not yet provided any proof.

I quoted Gibbons speaking of Prots as "separated brethren" and promoting religious liberty.  You simply ignored it.

Pius XI himself used the term, "separated brethren", so nothing to see here. The term didn't make Gibbons a modernist. 

Correct.  So did Leo XIII ... both in the clear context of calling for their conversion and return to the true faith.  Gibbons, on the other hand, simply uses the expression in an egalitarian sense, and in a religious indifferentist sense, as it's used today by the Modernists, "though they do not SHARE our faith".  That's the difference, but you're obviously blind to it because you have a statue of Gibbons on your mantle somewhere.

Gibbons was unquestionably an Americanist and proto-Modernist, despite your pathetic denials.

Pope Leo XIII addressed Testem Benevolentiae primarily to Gibbons, who then simply blew it off and claimed that they believed no such things ... which was demonstrably false.
