IIRC this topic is covered in Solange Hertz's Americanism. If there wasn't a ton of Thanksgiving preps to still be done, I'd pull it out, but… (more excuse to follow). :D

The Star-Spangled Heresy: Americanism
Americanism is a heresy which five different popes have condemned. But what is it? Perhaps the best characterization of Americanism was given by Leo XIII's biographer Msgr. T'Serclaes: "A spirit of independence which passed too easily from the political to the religious sphere."
"That the Church and State ought to be separated is an absolutely false and pernicious error ... It limits the action of the State exclusively to the pursuit of public prosperity during this life, though this is only the proximate raison d'etre of political societies." - Pope St. Pius X in
Vehementer"It is unlawful to follow one line of conduct in private life and another in public, respecting privately the authority of the Church, but publicly rejecting it; for this would amount to joining together good and evil, and to putting man in conflict with himself; whereas he ought always to be consistent, and never in the least point not in any condition of life to swerve from Christian virtue." - Leo XIII in
Immortale Dei"Believe me, the evil I denounce is more terrible than the Revolution, more terrible even than the Commune. I have always condemned liberal Catholicism, and I will condemn it forty times over if it be necessary!" - Pius IX

Searcher of MajestySolange Hertz's Biography:
An established writer before the Second Vatican Council, Solange Hertz wrote for most Catholic periodicals and had five books to her credit, one a selection of the Catholic Literary Foundation. When she refused to adjust her theology to the new “Spirit of Vatican II,” her manuscripts almost overnight became unacceptable to her former editors. After a series of articles on feminine spirituality for the old
Triumph magazine, she continued speaking for tradition by successfully producing
The Thought of Their Heart and
Sin Revisited on her own.
