Bishop Strickland : How were they to reconcile Pius X warnings against modernism with V2's desire for greater engagement with contemporary society?
Bishop Strickland about modernism within the Church of Leo XIVThank you for joining me today.
There are some words that once occupied a central place in the life of the Catholic Church but are now seldom heard, and I want to talk about one of those words today. The word is “modernism.”
Ask the average Catholic today what modernism is, and many will not know how to answer. Ask when they last heard a sermon about it, and many would say, “Never.”
Yet there was a time when the Church regarded modernism as such a grave danger that Pope St. Pius X devoted an entire encyclical to exposing it. In 1907, in Pascendi Dominici Gregis, he called modernism “the synthesis of all heresies.” Those are extraordinary words. Popes do not use language like that lightly.
If St. Pius X believed modernism was the synthesis of all heresies, then a question naturally follows: What happened?
Did modernism simply disappear? Or have we reached a point where the Church’s own warnings have largely faded from memory?
Those are the questions I would like us to consider together today. This is not merely an historical discussion. It is not an academic exercise. I believe it touches the very heart of the crisis we are living through in the Church.
Before we can understand where we are today, however, we must understand what modernism actually is.
Many people mistakenly think modernism simply means making the Church more modern, using contemporary language, or adapting certain pastoral approaches. That is not what Pope St. Pius X was condemning. Modernism is much deeper than that. It is a way of thinking. It is a mentality. It is a method of approaching revelation itself.
Instead of beginning with the question, “What has God revealed?” modernism gradually begins asking, “What can modern man accept?” Instead of measuring the world by the unchanging truth of Christ, it begins measuring revealed truth by the changing assumptions of the world. That is why modernism is so dangerous.
It is not simply one doctrinal error among many. Rather, it becomes a principle by which every doctrine can eventually be reinterpreted. That is why St. Pius X described it as “the synthesis of all heresies.”
Every previous heresy attacked some particular truth revealed by God. Modernism attacks the very foundation upon which revealed truth rests. It subtly shifts the center of gravity away from Divine Revelation and toward human experience, historical development, and contemporary culture.
As Catholics, however, we know that Jesus Christ is “the same yesterday, today, and forever.” Truth does not evolve. God does not change. Divine Revelation does not become obsolete because the culture changes. Sacred Scripture reminds us very clearly: “For the wisdom of this world is foolishness with God.” Those words from St. Paul are as true today as they were when they were first written.
Likewise, in Romans we read: “Be not conformed to this world, but be reformed in the newness of your mind.”
Notice the direction. The Church is called to transform the world. She is never called to allow herself to be transformed by the world. That distinction lies at the heart of this discussion.
Long before 1907, the seeds of modernism had already begun appearing in theological circles. Throughout the nineteenth century, various ideas emerged that attempted to reinterpret the Catholic faith through the lens of modern philosophy, historical criticism, rationalism, and liberal thought.
Pope Pius IX warned against many of these tendencies. But it was Pope St. Pius X who recognized that these ideas were not isolated errors. They formed an entire system. They shared a common spirit. That spirit is what he called modernism.
In Pascendi Dominici Gregis, St. Pius X carefully exposed that system before condemning it. Near the conclusion of the encyclical, he anticipated criticism from those who would say he had spent too much time explaining modernist thought. His response is profoundly important. He explained that it was necessary to expose modernism completely because its errors were often concealed beneath language that appeared orthodox while gradually emptying traditional doctrine of its meaning.
Those words deserve our attention today perhaps even more than they did in 1907. Because one of the defining characteristics of modernism is that it rarely announces itself openly. It often speaks the language of Catholicism while quietly changing the underlying meaning. That is precisely why St Pius X believed the danger was so great.
He understood that modernism did not usually present itself as an outright rejection of the Catholic faith. It did not typically begin by denying the divinity of Christ, rejecting the sacraments, or openly repudiating the authority of the Church. Rather, it worked more subtly. It sought to reinterpret the faith from within. It retained familiar language while gradually changing the meaning behind that language. It proposed that doctrine should develop in such a way that it would increasingly conform to the thought of each successive age.
That is why modernism has often been described not simply as a collection of errors, but as a way of thinking – a habit of mind that places the judgment of the modern world above the unchanging truth that God has revealed.
That is why St. Pius X believed it possessed the “sap and substance,” if you will, of every previous heresy. Every major heresy in the history of the Church attacked some particular article of faith. Modernism, however, attacked something even more fundamental. It challenged the very source and certainty of revealed truth. Once revelation itself is made subject to changing human experience, then no doctrine remains permanently secure. Everything becomes open to reinterpretation. Everything becomes negotiable.
That is why the Holy Father called it “the synthesis of all heresies.”
He was not engaging in exaggeration. He was acting as the Supreme Pastor of the Church, warning the faithful that an error had arisen which threatened not merely one doctrine but the very foundation upon which all doctrine rests. Recognizing the seriousness of this danger, St. Pius X did something extraordinary.
In 1910, only three years after issuing Pascendi Dominici Gregis, he required the Oath Against Modernism. Priests, bishops, professors of theology, seminary faculty, and others entrusted with teaching the Catholic faith were required to swear publicly that they rejected the principles of modernism and would faithfully preserve the doctrine handed down from the Apostles.
This was not a temporary disciplinary measure. It reflected the conviction that modernism posed an ongoing danger to the life of the Church. That historical fact is important because it reminds us how seriously the Church once regarded the threat.
Every Catholic priest ordained between 1910 and 1967 was required to take that oath. Consequently, with very few exceptions, every bishop, cardinal, and theological expert who participated in the Second Vatican Council had taken the Oath Against Modernism earlier in his priesthood. That fact should cause all of us to pause. It raises important questions that deserve thoughtful reflection.
How were those bishops to understand the oath they had sworn while participating in a council that sought a new relationship between the Church and the modern world? How were they to reconcile St. Pius X’s uncompromising warnings against modernism with the Council’s desire for greater engagement with contemporary society? These are not questions that can simply be dismissed. They deserve careful, honest, and prayerful consideration.
The Church has always engaged the world. From the Apostles onward, Christians have proclaimed the Gospel to every culture and every age. Evangelization necessarily involves dialogue. But dialogue has never meant allowing the world to determine the content of Divine Revelation.
The mission of the Church is not to adapt revealed truth to the age. The mission of the Church is to bring every age into conformity with Jesus Christ.
There is an enormous difference between proclaiming the Gospel to the world and permitting the world to become the standard by which the Gospel is interpreted. That distinction, I believe, lies at the heart of the crisis we are witnessing today.
It is at this point that we must speak honestly about the Second Vatican Council. The Council itself was unlike previous ecumenical councils in one important respect. It did not define new dogmas or issue new anathemas against heresy. Rather, it described itself primarily as pastoral in character. Its stated purpose was to present the perennial truths of the Catholic faith in a manner more accessible to the modern world.
No one can question the Church’s desire to proclaim the Gospel to every generation. That has always been her mission. The question before us is a different one. Can the Church engage the modern world without absorbing the assumptions of the modern world? That question is more urgent today than ever before.
One of the Council’s principal documents, Gaudium et Spes – the Pastoral Constitution on the Church in the Modern World – set forth a vision of engagement between the Church and contemporary society that has profoundly influenced Catholic life during the past six decades. Many have seen this as a positive development. Others have raised serious concerns that some of its language has been interpreted in ways that move beyond authentic engagement and toward accommodation with the spirit of the age.
These concerns cannot simply be dismissed. They deserve careful consideration precisely because St. Pius X warned us that modernism often enters the Church gradually, clothed in language that appears entirely reasonable.
Years after the Council, Cardinal Joseph Ratzinger – who would later become Pope Benedict XVI – made a remarkable observation. Speaking about Gaudium et Spes, he suggested that the document functioned, in a certain sense, as a “counter-syllabus,” an attempt at reconciliation between the Church and the modern age after the sharp conflicts of the nineteenth century. Those words have generated much discussion. For me, they also raise an unavoidable question.
If the Church had previously warned so forcefully about the dangers posed by liberalism, rationalism, and the spirit of the age – warnings found especially in the teachings of Blessed Pius IX and St. Pius X – what exactly was being reconciled?
Were the concerns that prompted those solemn warnings no longer valid? Had the dangers somehow disappeared? Or had the Church simply adopted a different pastoral approach while leaving those earlier warnings entirely intact? These are questions that deserve thoughtful answers.
Cardinal Ratzinger would later propose what has become known as the “hermeneutic of continuity.” His conviction was that the Second Vatican Council must always be interpreted in continuity with the Church’s previous teaching, never as a rupture with the past. That principle is an important one. Every Catholic should desire continuity with the constant teaching of the Church. Yet many faithful Catholics continue to struggle with an honest question.
If modernism remains the “synthesis of all heresies,” as St. Pius X declared, how are Catholics to understand passages that have often been interpreted as encouraging an ever greater openness to the assumptions and values of the contemporary world? If there is continuity, it should be possible to demonstrate that continuity clearly. If there is harmony, that harmony should be visible not only in theory but also in practice.
Unfortunately, when we look at the life of the Church during the decades since the Council, many Catholics see not greater clarity but greater confusion. We have witnessed confusion concerning doctrine. Confusion concerning morality. Confusion concerning the sacred liturgy. Confusion concerning the uniqueness of the Catholic faith. Confusion concerning the Church’s mission in the world.
Whether one attributes that confusion to mistaken interpretations of the Council, abuses committed in its name, or to the Council’s own pastoral language, the confusion itself cannot honestly be denied. And this brings me to what I believe is perhaps the most important point of this reflection.
The Church has never formally withdrawn St. Pius X’s condemnation of modernism. No pope has repealed Pascendi Dominici Gregis. No pope has declared that modernism is no longer a danger. No pope has stated that the Oath Against Modernism was based upon a misunderstanding of the faith. The condemnation remains part of the Church’s history and teaching. Yet in practice, it seems to have largely disappeared from our consciousness.
It is almost never preached. It is rarely taught. Many Catholics have never even heard the term. That seems to represent something very serious. It is what one respected Catholic scholar has described as a “covert nullification” of the Church’s condemnation of modernism. Not a formal nullification. Not an official repeal. But something perhaps even more subtle. A practical nullification through neglect.
A teaching can remain on the books while disappearing from the life of the Church. And if that happens, its influence is effectively lost, even though no one has formally denied it.
And that brings us to the present moment.
In recent months, our Holy Father, Pope Leo XIV, has begun a series of addresses encouraging Catholics throughout the world to study the documents of the Second Vatican Council more deeply and to renew their commitment to the path upon which the Church embarked in its wake. He has spoken of allowing the Council’s teachings to continue inspiring the life and mission of the Church.
As Catholics, we should always pray for the Holy Father. We should desire his success in leading the Church faithfully to Jesus Christ. Every pope bears an immense burden, and every pope deserves our prayers.
But precisely because I love the Church and pray daily for the Holy Father, I also believe difficult questions must sometimes be asked. If the Church’s condemnation of modernism remains in force, why does it seem to receive so little attention today? If St. Pius X believed modernism to be the synthesis of all heresies, why has that warning become almost invisible in the life of the Church?
If the Church is encouraging even greater engagement with the modern world, how do we ensure that such engagement never becomes accommodation to the spirit of the age? Those are not questions born of disobedience. They are questions born of love for the Church.
Throughout her history the Church has always needed courageous men and women willing to ask whether we remain faithful to what has been handed down from the Apostles. The Deposit of Faith does not belong to any pope. It does not belong to any bishop. It does not belong to any theologian. It belongs to Jesus Christ. The Church is its guardian, not its author.
For that reason, every generation – including our own – is measured by the Deposit of Faith, not the other way around.
My concern is that we have reached a point where the language of dialogue has too often overshadowed the language of conversion. Certainly, authentic dialogue has its place. We speak with others because we desire their salvation. We listen so that we may better proclaim Christ. But dialogue can never become an end in itself. The Church does not exist simply to accompany the world. She exists to call the world to repentance, to faith, and to eternal life in Jesus Christ.
There is a profound difference between loving the world enough to evangelize it and loving the world’s approval so much that we hesitate to proclaim difficult truths. That distinction is essential.
It seems to me that one of the great temptations of our time is to seek peace with the spirit of the age. Yet Sacred Scripture repeatedly warns us against that temptation. St. Paul tells us plainly that “the wisdom of this world is foolishness with God.”
He does not say that the wisdom of this world merely needs to be refined. He does not say it simply needs to be supplemented. He says it is foolishness with God.
Likewise, Our Lord Himself tells us, “If the world hate you, know ye, that it hath hated me before you.”
The Church has never measured her faithfulness by the applause of the world. She has measured her faithfulness by fidelity to Christ. For that reason, I believe we must recover the courage to speak once again about modernism – not as a relic of the early twentieth century, but as a living danger that still confronts the Church today. If we no longer recognize the danger, we can no longer resist it.
If we no longer teach what St. Pius X taught so forcefully, future generations will not even know that such a warning was ever given. And that would be a tragedy.
My prayer is not that we return to a particular decade in history. My prayer is that we return to the perennial wisdom of the Church – the wisdom of Sacred Scripture, Sacred Tradition, the Fathers, the Doctors of the Church, the saints, and the perennial Magisterium that faithfully guarded the Deposit of Faith through the centuries.
That is not looking backward. That is remaining rooted.
A tree that cuts itself off from its roots does not become more alive. It dies. The Church must always remain rooted in Jesus Christ, who is the same yesterday, today, and forever.
My dear brothers and sisters, we are living in extraordinary times. Around us we see nations in turmoil, families under attack, confusion about the most basic truths of human nature, assaults on the sanctity of life, attacks upon marriage and the family, and increasing hostility toward the Gospel of Jesus Christ. At such a moment, the Church cannot afford uncertainty about her own identity. She cannot afford to lose confidence in the timeless truths entrusted to her by Christ. Nor can she afford to forget the solemn warnings that have been given by those who came before us.
St. Pius X did not condemn modernism because he feared progress. He condemned it because he loved Jesus Christ. He loved His Church. He loved the truth. And he recognized that whenever the spirit of the age begins to replace the mind of Christ, the faithful are placed in grave spiritual danger. That warning has never been formally withdrawn. It has never been repealed.
Yet I fear that, in practice, it has too often been forgotten.
I believe we are living through what can only be described as a practical nullification of the Church’s condemnation of modernism – not by formal decree, but through neglect, silence, and the gradual disappearance of this subject from the Church’s preaching, teaching, and formation. If that is the truth, then we cannot remain silent. Silence has never defeated error. Only truth defeats error. Only Christ defeats error.
The answer is not anger. The answer is not bitterness. The answer is not despair. The answer is holiness. The answer is fidelity. The answer is returning once again to the perennial teachings of the Catholic Church – to Sacred Scripture, Sacred Tradition, the Fathers and Doctors of the Church, the saints, and the perennial Magisterium that has faithfully handed on the Deposit of Faith from generation to generation.
The Church does not need to reinvent herself. She needs to remember who she is. She is the Mystical Body of Christ. She is the guardian of Divine Revelation. She is called to sanctify the world – not to be sanctified by it.
My brothers and sisters, I ask you to do three things.
First, pray. Pray every day for the Holy Father. Pray for all bishops, priests, deacons, and religious. They carry immense responsibilities, and they need the grace of God now more than ever.
Second, study your faith. Read Sacred Scripture. Read the Catechism. Read Pascendi Dominici Gregis. Read the great papal encyclicals that have guided the Church through previous crises. Know not only what the Church teaches but why she teaches it.
Third, remain faithful. Do not be shaken by confusion. Do not allow discouragement to rob you of hope. Do not measure truth by popularity or by the approval of the world. Measure everything by Jesus Christ who is the Truth.
Remember the words of St. Paul: “Be not conformed to this world, but be reformed in the newness of your mind.” That exhortation is just as urgent today as when it was first written.
Our task is not to bring Christ into conformity with the world. Our task is to bring the world to Jesus Christ. That has always been the mission of the Church. That remains the mission of the Church. And that, by the grace of God, must remain our mission as well.
May Our Lady, Seat of Wisdom, pray for us.
May St. Joseph, Protector of the Universal Church, intercede for us.
May St. Pius X, who courageously defended the faith entrusted to the Apostles, obtain for us the wisdom, the courage, and the perseverance to stand firmly for the truth in our own day.
And may Almighty God bless you, keep you steadfast in the Catholic faith, and lead all of us safely home to the glory of His heavenly kingdom.
