Cardinal Burke was particularly incensed by reports that Mr Bannon might make a film about closet homosexuality within the Catholic Church.
The cardinal said the former White House strategist had had a meeting with Frédéric Martel, a French journalist who recently wrote an expose about gay priests called “In the Closet of the Vatican.”
The idea was to turn the book, which was published in February and alleges that up to 80% of Catholic clergy are either openly gay or in denial about being gay, into a film.
“I do not, in any way, agree with Mr. Bannon’s assessment of the book in question,” the cardinal said.
“Furthermore, I am not at all of the mind that the book should be made into a film. I disagree completely with a number of Mr. Bannon’s statements regarding the doctrine and discipline of the Roman Catholic Church.”
It was “objectionable” that Mr Bannon had called into question the Church’s insistence on celibacy for priests, he said.
Mr Harnwell confirmed that he had set up the meeting between Mr Bannon and the French author.
He described Cardinal Burke as “a principal guiding figure to the DHI, not to mention a good friend, over many years.”
