This confusion, I think, is due to the fact that Catholics have appropriated secular-political definitions of what it means to be "liberal" or "conservative",
essentially equating indicators of political liberalism with theological liberalism. In the political realm, for example, a liberal is likely to be in favor of same sex marriage, abortion, and at least an indifferentist on religious matters, if not an outright agnostic or atheist. These are what are adopted as the indicators of liberalism. Thus, when it comes to a Catholic prelate or theologian, it is the presence or lack of these indicators that determine whether that individual is "liberal" or not. Understood this way, Cardinal Timothy Dolan cannot be liberal because he is fiercely Pro-Life; Cardinal Schönborn is not liberal because he writes beautiful things about the need for society to turn to God; Cardinal Bergoglio could not be a liberal because he had defended traditional marriage in strong language during his time in Argentina. It is not my purpose to suggest that the aforementioned prelates
are liberals, only point out that the indicators for who is and is not a 'liberal' are usually social-moral questions lifted from the political spectrum.
But is this what it means to be 'liberal' in the traditional, Catholic sense? When Bl. Pius IX or Leo XIII or St. Pius X wrote scathingly against "liberalism", what were they condemning? Were they condemning homosexual marriage, or abortion, or agnosticism?
Those moral issues certainly are part of liberalism, but anyone who has really studied the thought of the pre-Conciliar popes on this question knows that these moral issues are fundamentally not what the popes of the 19th century were worried about. Fr. Salvany, in his classic work
Liberalism is a Sin, devotes an entire book to demolishing the errors of liberalism and never mentioned abortion or homosexuality. This is because for Salvany, as well as Bl. Pius IX and the other pre-Conciliar popes,
liberalism is primarily a troubling theological trend within Catholicism, not a position on hot-button moral issues. It has to do with holding certain
theological opinions, most of which are not relatable to any corresponding positions on the political spectrum, because they are problems internal to Catholic theological thought. This is why Fr. Salvany can write a whole book against liberalism and not mention these moral indicators; he simply does not see them as the essence of liberalism.
Once we understand this, we will begin to see why there is a divergence here; why where one sees a conservative prelate, another sees a liberal or modernist. If you are still thinking inside the liberal-conservative political paradigm, you may be surprised to see what the Church's definition of a liberal-progressive actually is. It is certainly not the same thing as a political liberal in the American sense. If not, then what is the profile of a theological liberal, according to the Church's tradition? It is hard to nail down every point, but here a few indicators of liberalism we have culled from some of the more famous documents of the pre-Conciliar Church:
A liberal believes that every man is free to embrace and publicly profess whatever religion he deems true, and that good hope may be entertained for the salvation of these people outside the Church. (Syllabus, 15-17)
A liberal believes that it is no longer expedient for Catholicism to be the formal religion of the State; liberals thus profess an American style separation of Church and State and deny that religious liberty will lead to indifferentism (ibid., 77-78).
A liberal dismisses the injunction of Pope Agatho, affirmed by Gregory XVI in Mirari Vos, that neither the content of the faith nor its expression ought to be changed. (Mirari Vos, 7)
A liberal believes that so long as members of non-Christian religions follow certain moral standards, salvation can be obtained. (ibid., 13). A liberal asserts the "liberty of conscience" (ibid., 14).
A liberal believes in an absolute right to freedom of speech, especially the freedom to publish and spread falsehoods in print and online. Note, even if the content of this speech is disagreed with, the liberal still asserts that there is a right for it to be promulgated. This belief in unfettered freedom of publishing is a tenet of liberalism (ibid., 15).
Liberals assert that the Church cannot pass judgment on the content and methodology of human science. (Lamentabile Sane, 5).
A liberal believes that the Gospel of John was not composed by the beloved Apostle, but by a "Johannine community" (ibid., 18).
A liberal believes that Christianity must be adapted to fit the needs of different times and places (ibid., 59).
A liberal believes that the Church's traditional understanding of creation of the world be reevaluated in light of modern scientific knowledge (ibid., 64).
A liberal believes the fundamentally center of all religion is the religious experience, the heeding of the religious sense of man (Pascendi, 6, 10).
A liberal cannot distinguish between the natural and the supernatural; he is ever naturalizing what is supernatural, whilst simultaneously affirming a supernatural or soteriological importance to things that are merely natural (ibid., 7; see also Humani generis, 26). Mere natural virtue is treated as meritorious as supernatural virtue, and the whole uniqueness of supernatural faith is implicitly denied since natural faith is considered equally salvific (i.e., the "faith" of the non-Christian being treated as meritorious).
Liberals believe that dogma should evolve with the changing sensibilities of man (ibid., 13).
Liberals believe that non-Christians, such as Muslims and pagans, can have authentic, and valuable religious experiences that must be affirmed (ibid., 14).
A liberal believes that the Sacred Scriptures are primarily understood as the record of the "experience" of God's pilgrim people on their journey of faith. Sacred history is a narrative of various experiential encounters with God - a chronicle of experiences (ibid., 21-22).
A liberal believes it is wrong for the Church to meddle in any political affairs; for the Church to trace out and prescribe for the citizen any line of action, on any pretext whatsoever, is to be guilty of an abuse of authority (ibid., 24).
The liberal believes that everything in the Church ought to be updated - to change and evolve with the times. Liturgy, discipline, Church structure all ought to be modified to fit the spiritual needs of an ever changing society (ibid., 26).
A liberal believes that the Bible may contain historical or scientific errors, but, since the subject of these books is not science or history, but only religion and morals, it is not a 'real' error, since the fundamental nature of the Bible is to teach about faith, not history (ibid., 36).
A liberal prefers modern philosophical systems to Scholastic philosophy (ibid., 38).
A liberal believes that the entire structure of the Church ought to be reformed in order to reflect the more democratic sensibilities of the modern world (ibid.) - how about replacing the papal coronation with an inaugural Mass?
A liberal believes that authority in the Church is much too concentrated should be decentralized (ibid.).
Liberals believe that, while the Church Fathers are worthy of veneration, their absence of critical textual erudition and knowledge of ancient history make their interpretations of Scripture suspect (ibid., 42).
A liberal believes that Catholics ought to ignore the differences that divide us from Protestants, Muslims, and other people of faith, and focusing on what unites us, join forces to combat secularism and atheism (Humani generis, 11).
A liberal believes that the needs of the times justify altering terminology long established in the Church and freeing our theology from philosophical concepts held by Catholic teachers (ibid., 14).
A liberal denies that the Church of Jesus Christ and the Holy Roman Catholic Church are one and the same, but prefers to waffle and equivocate on this point (ibid., 27).
Liberals believe that it is a foregone conclusion, already scientifically proven, that the human body was the result of evolution (ibid., 36).
A liberal denies that it falls to the teaching authority of the Church to decide whether evolution can be held as a viable position for a Catholic (ibid.).
Liberals deny the existence of a literal Adam and Eve (ibid., 37).
Liberals believe that instead of two first parents, we had multiple first parents (ibid.).
A liberal denies that the first eleven chapters of Genesis are historical in nature (ibid., 38).
A liberal priest, bishop or theologian falsely believes that he can still maintain a clear conscience without insisting that his pupils and those under his authority religiously accept the teaching authority of the Church, including the condemnation of all of the above propositions (ibid., 42).
As you can see, one need not profess same-sex marriage, abortion, favoring national health insurance or any of the current hot-button indicators of political liberalism have anything to do with theological liberalism. Forget whether a prelate is Pro-Life or not; does he believe separation of Church and State is ideal? If so, then he is a liberal.
Is he clamoring for decentralization of the Church, more power for the national bishops' conferences, or an internationalization of the Roman Curia? Liberal.
Does he speak about Genesis in terms of "the Bible doesn't teach scientific truth because it is not primarily a scientific book"? Liberal.
Does he believe in absolute freedom of speech and freedom of the press? Liberal.
Is he praising the religious experiences of non-Christian cultures, affirming that they have some sort of value in God's eyes and suggesting that all people are somehow communing with God through their own religious traditions? Liberal.
Does he state that the Church needs to figure out how to spread its message with new vocabulary to suit the temperament of modern man?
Liberal.
Does he believe in a loose alliance of all moral, religious people against secularism?
Liberal.
Does he confuse natural with supernatural virtue, praising the natural virtues of pagans of anyone else as if these are supernaturally pleasing to God?
Liberal.
Does he deny,
on national television, that there were a historic Adam and Eve and then look like a fool when asked to explain original sin (which Pius XII specifically said would be problematic when the historical Adam and Eve are denied)? If so, then he is a
liberal.
Once you understand what the profile of a theological liberal looks like, you begin to realize there are many more around than you first thought.
