EWTN News reports that Vice President JD Vance, a Catholic, welcomed the release of Leo XIV’s encyclical *Magnifica Humanitas* as “profound,” stating that moral principles remain fixed while their application evolves with changing times. Vance explicitly endorsed updating “just war” doctrine and rethinking “the entire Catholic social teaching in light of the new world,” framing this as a natural and necessary adaptation. This statement is not merely a political opinion; it is a direct articulation of the condemned modernist heresy of the evolution of dogmas, a heresy that strikes at the very heart of immutable Catholic truth.

The Condemned Heresy of Doctrinal Evolution
Vance’s assertion that “the principles never change, but the way you apply these principles does, because the world changes” is a textbook restatement of the modernist error condemned in the starkest terms by Saint Pius X. The very notion that Catholic doctrine requires “updating” or “rethinking” in light of “new technologies,” “new warfare,” or “new ways of human beings interacting” is the poisoned fruit of the rationalist vine that the Church has repeatedly cut down.
In *Lamentabili Sane Exitu* (1907), the Holy Office under Saint Pius X condemned the proposition that “Truth changes with man, because it develops with him, in him, and through him” (Proposition 58). Vance’s logic is identical: truth — or at least its application — changes because man and his world change. This is not Catholic teaching; it is philosophical relativism wearing a cassock. The Council of the Vatican, in its Dogmatic Constitution *Dei Filius*, defined that “the doctrine of faith which God has revealed has not been proposed to human minds to be perfected by them as if it were a philosophical system, but as a divine deposit committed to the Bride of Christ to be faithfully guarded and infallibly interpreted.” The deposit of faith is not a living document subject to editorial revision by each generation; it is a sacred trust, *depositum fidei*, handed down whole and entire.
Pius IX’s *Syllabus of Errors* condemned the proposition that “Divine revelation is imperfect, and therefore subject to a continual and indefinite progress, corresponding with the advancement of human reason” (Proposition 5). When Vance speaks of “rethinking the entire Catholic social teaching in light of the new world,” he is precisely advocating this condemned “indefinite progress.” There is no “new world” that can alter what God has revealed. The world changes; God does not (Malachi 3:6). The moral law is not a software patch to be uploaded when circumstances demand it; it is the eternal law of God written into the fabric of creation.
The “Just War” Doctrine: Immutable, Not Negotiable
Vance’s specific reference to updating “just war” doctrine reveals a dangerous ignorance — or willful rejection — of the Church’s unchanging teaching. The just war doctrine, rooted in the writings of Saint Augustine and Saint Thomas Aquinas, and codified in the Church’s moral theology, is not a policy platform subject to revision with each new military technology. Its criteria — legitimate authority, just cause, right intention, last resort, probability of success, and proportionality — are derived from the natural law and divine law, neither of which changes because mankind invents more efficient means of killing.
Saint Thomas Aquinas, in the *Summa Theologiae* (II-II, Q. 40), established the principles of just war not as suggestions for diplomatic flexibility but as binding moral requirements. To suggest that “new technologies and warfare” require updating this doctrine is to imply that the moral law is contingent upon human invention — a proposition that inverts the proper order. God’s law governs man’s actions; man’s actions do not rewrite God’s law. The Catechism of the Council of Trent taught that the Church is the custodian and interpreter of divine law, not its editor-in-chief, tasked with making the faith palatable to each successive age.
This is the very error that Saint Pius X identified as the essence of Modernism: the belief that doctrine must evolve because human consciousness evolves. In *Pascendi Dominici Gregis*, the Saint described the modernist as one who “is not content to believe what God has revealed, but wants to know why God revealed it, and whether it could have been otherwise.” Vance’s pragmatic framing — “the world changes, right?” — is precisely this modernist temperament: the faith must accommodate itself to the world, rather than the world being called to conform itself to the faith.
The Symptomatic Silence: No Supernatural Foundation
What is most revealing in Vance’s statement is not only what he says, but what he omits entirely. There is no mention of God’s eternal law, of the natural law as participation in the divine law, of the authority of the Magisterium as the sole authentic interpreter of revelation, of the necessity of grace, of the reality of sin, or of the supernatural end of man. His framing is entirely horizontal: “new technologies,” “new warfare,” “new ways of human beings interacting.” This is the language of sociology, not theology; of the State Department, not the Vatican Council.
The true Catholic position on the relationship between unchanging principles and changing circumstances was articulated by Pope Leo XIII in *Immortale Dei*: the Church applies eternal principles to temporal affairs, but the principles themselves are not subject to revision. Application is prudential; doctrine is dogmatic. Vance collapses this distinction entirely, treating doctrine itself as a matter of application — that is, as a matter of human judgment rather than divine revelation.
Pius XI, in *Quas Primas*, proclaimed the reign of Christ the King over all nations and all aspects of human life, precisely to combat the secularist error that there are domains of human activity — politics, technology, warfare — that operate outside the sovereignty of Christ. Vance’s framing implicitly carves out a secular sphere where “the world changes” and doctrine must follow, directly contradicting the social kingship of Christ. **The state does not dictate the terms of moral theology; Christ the King dictates the terms by which states themselves must abide.**
The Political Context: A Catholic in Service of Caesar
It must also be noted that Vance’s comments come from a man who serves the most powerful secular government on earth — a government historically hostile to Catholic teaching on the sanctity of life, the indissolubility of marriage, and the rights of the Church. That a Catholic vice president would publicly endorse the “updating” of Catholic moral teaching to accommodate “new realities” is not surprising; it is the predictable consequence of the conciliar revolution’s systematic dismantling of the Church’s authority in the public square.
Vance previously stated that “in some cases it would be best for the Vatican to stick to matters of morality” and “let the president of the United States stick to dictating American public policy.” This statement alone reveals the secularist framework within which he operates: morality is the Church’s domain (and a shrinking one, by his reckoning), while public policy is Caesar’s. This is precisely the separation of Church and State condemned by Pius IX in the *Syllabus* (Proposition 55: “The Church ought to be separated from the State, and the State from the Church”) and by Gregory XVI in *Mirari Vos*. The Catholic position is not that the Church should “stick to matters of morality” while Caesar does as he pleases; it is that **Caesar himself is subject to the moral law of God**, and the Church has both the right and the duty to declare what that law demands of rulers and nations.
The Conciliar Context: Leo XIV’s Encyclical as Continuation of Apostasy
The encyclical *Magnifica Humanitas* itself — the document Vance praises — must be understood within the context of the post-conciliar apostasy. Leo XIV, as a usurper occupying the Chair of Peter by the authority of a council (Vatican II) that itself produced documents contradicting defined Catholic dogma, possesses no authority to bind the faithful. His encyclicals, far from being “profound” contributions to Catholic teaching, are instruments of the ongoing modernist revolution within the conciliar sect.
The title itself — *Magnifica Humanitas*, “Magnificent Humanity” — is a telltale sign. The cult of man, the exaltation of “humanity” as an object of veneration, is the hallmark of the religion of Modernism, which Saint Pius X described as the “synthesis of all errors.” The true religion glorifies God; the religion of the conciar sect glorifies man. “What is man, that Thou art mindful of him?” (Psalm 8:4) — this is the Catholic question. The modernist answer is: man is everything, and God is the servant of human progress.
Vance’s endorsement of this encyclical, and his articulation of the modernist principle underlying it, places him squarely within the camp of those who would accommodate the faith to the world rather than transform the world through the faith. It is the old temptation: *you will be like God* (Genesis 3:5). Modernism promises that man can be like God — that he can determine truth for himself, update doctrine as he sees fit, and build the kingdom of God through human progress rather than divine grace. This is the lie that has animated every heresy from Pelagianism to the present apostasy.
Conclusion: Immutable Truth in a World of Lies
JD Vance’s comments are not merely politically unwise or theologically uninformed; they are a public profession of the modernist heresy condemned by the pre-conciliar Magisterium. The claim that Catholic moral teaching must be “updated” for a “changing world” is the claim that God’s truth is insufficient for the present age — a claim that is, in its essence, blasphemous.
The Catholic position is, and has always been, that **the truth of God is eternal, immutable, and sufficient for all times and all places**. The world does not change the faith; the faith judges the world. When the world contradicts the faith, it is the world that must change — not by “updating” doctrine, but by converting hearts to the unchanging truth of Jesus Christ, true God and true Man, whose Kingdom shall have no end.
Let those who have ears, hear: the spirit of the age is not the Spirit of God. And those who confuse the two serve not the Church of Christ, but the synagogue of Satan.
