8.63. Isn’t it still okay to attend a traditional Latin Mass as long as it’s reverent—even if it’s offered “una cum” Leo XIV?
Many traditional Catholics, especially those newly awakening to the crisis, are unsure whether they can attend Latin Masses that are offered in union with (una cum) the post-Vatican II “popes,” such as Francis or Leo XIV. They may recognize that these men promote heresy and preside over a counterfeit Church—but believe that as long as the Mass is “reverent,” it’s still spiritually beneficial.
But the issue is far more serious. When a Mass is offered una cum [Name] our pope, it is a liturgical act of communion—a public profession that the man named is the visible head of the true Church, with lawful authority from Christ. If that man is an antipope, heretic, or enemy of the Faith, then offering Mass in his name is a lie, a sacrilege, and a scandal. It falsely affirms the Vatican II sect as the true Church, when it is in fact a counterfeit.
Below is a comparison showing why Catholics must reject una cum Masses under false “popes” and instead unite with the faithful remnant, where the true Faith, sacraments, and visible Church continue in purity.
| Category | Una Cum Church (Vatican II Sect) | Faithful Remnant (True Catholic Church) | Remarks |
|---|---|---|---|
| Liturgical Communion | Mass is offered “una cum Francisco/Leo XIV”—in union with a false pope | Mass excludes name of false pope; affirms sede vacante status of Holy See | To name a heretic in the Canon is to unite with his false religion |
| Ecclesiology | Affirms the visibility and unity of a counterfeit church founded on error | Affirms the true visible Church through the remnant clergy and faithful | The Church must always be visible—but not in apostasy |
| Unity with Rome | Externally united to the Vatican II establishment and its Modernist hierarchy | Internally united to the unchanging Rome of the popes and saints | True unity is doctrinal, not geographical or political |
| Profession of Faith | Implicitly professes acceptance of the Vatican II religion and its pope | Explicitly rejects the errors of Vatican II and its usurpers | Lex orandi, lex credendi: prayer expresses belief—false prayer affirms false belief |
| Scandal | Leads others to believe that the Novus Ordo pope is legitimate | Gives clear witness that the Chair of Peter is currently vacant | Attending una cum Masses perpetuates confusion and compromise |
| Grace and Validity | Even if valid, grace is diminished or blocked by false ecclesial unity | Graces flow unimpeded where there is full doctrinal purity and integrity | Participation in error taints even a valid sacrament |
| Clerical Authority | Priests operate under a false “jurisdiction” and illegitimate authority | Priests act under supplied jurisdiction for the salvation of souls | Jurisdiction must serve the true Faith, not false structures |
| Fruits | Ongoing confusion, R&R contradiction, split loyalties | Clarity, peace of conscience, doctrinal coherence | “By their fruits you shall know them” (Matt. 7:16) |
Summary:
The Holy Sacrifice of the Mass is not a private devotion—it is the public worship of the Church, and therefore must profess the true Faith and affirm the true hierarchy. To offer or attend a Mass una cum a false pope is to lie in prayer, to profess union with heresy, and to affirm a counterfeit Church.
The visibility of the Church does not mean being united to Rome at all costs—it means remaining visibly united to the Catholic Faith. The faithful remnant, though small and scattered, retains the marks of the Church: unity of faith, true sacraments, apostolic succession, and sanctity of doctrine.
As Pope Pius IX declared:
“Those who adhere to errors and separate themselves from the truth do not belong to the Church.”
