Imagine a government deciding which parts of a church are sacred. The altar, yes. The nave, no. The chapels, the dome, the atrium, the vestibule, and great bronze doors—no as well. The faithful may pray here, but not there, and only after passing through a state-run exhibition with a political and ideological message before entering. It might sound invented, but it is happening right now in Spain.  The target is the Basilica of the Holy Cross in the Valley of Cuelgamuros. There is nothing else like it in the Christian world. It extends some 260 meters into the granite of the Sierra de Guadarrama, making it longer than St. Peter’s Basilica in Rome. Above it rises the tallest cross on earth, a 152-meter monument of stone.   Consecrated in 1960 and entrusted since 1958 to a Benedictine abbey that reports directly to the pope, it contains beneath its floor the remains of more than 33,000 dead from both sides of the Spanish Civil War, including approximately 140 men and women whom the Church has raised to Her altars as saints, blesseds, and servants of God.   It is a living temple and an immense cemetery, and it is sacred from end to end. While it was built during Francisco Franco’s regime, the space was entrusted entirely to the Catholic Church. However, Spain’s socialist government is now using the site’s history as a pretext to undermine religious freedom.  A religious site is sacred in its entirety. A Catholic basilica is not merely religious at the altar and during the celebration of Mass. Its doors, its naves, and its chapels are dedicated to divine worship. And no government—none—has the authority to walk in and decide which of those spaces remain sacred and which do not.   What a faith considers sacred is for that faith to determine. This is neither a minor nor a sectarian matter. Religious freedom is not simply one liberty among many; it is the foundation upon which all the others rest.   Once a people is deprived of the right to follow conscience and worship freely, every remaining freedom becomes a privilege that the state may revoke at will. The Spanish Constitution guarantees freedom of religion, and so does Spain’s agreement with the Holy See, which expressly recognizes the inviolability of places of worship. Those guarantees are now being put to the test.  An assault is underway. Through a chain of laws, royal decrees, and an international architectural competition launched in 2025, the state has set in motion a project that reaches into the consecrated interior of the basilica. It strips the atrium and vestibule of their religious character, relocates the bronze doors, abolishes the basilica’s independent entrance, and forces worshippers to pass through a politically curated interpretation center before they can kneel in prayer. Most remarkably of all, the state has assumed for itself—through the fine print of its own administrative specifications—the authority to determine which parts of the basilica qualify as “places of worship” and which do not.  None of these measures carry the authorization of any religious authority with jurisdiction over the temple. Neither the Archbishop of Madrid, Cardinal José Cobo Cano—whose involvement has at times been invoked, though he holds no jurisdiction over the basilica—nor the Benedictine monks who serve as its lawful custodians have given their consent. The monks, in any event, could not: The Code of Canon Law itself bars them from agreeing to the partition of a consecrated church in the manner the project envisions. These are administrative acts being carried out upon a church that has never said yes.  And to justify intervention in a religious symbol, only one thing is ever invoked: the ghost of Franco. Wrap the project in the language of historical memory, summon the dictator, and an intrusion into the interior of a church is supposed to appear as an act of democratic housekeeping.   But remove that ghost and the real engine of the project becomes visible: a strain of anti-religious and anti-Catholic fanaticism that views a consecrated basilica, a place of prayer for thousands of people, not as sacred ground but as a trophy to be redesigned. This is not ultimately about the past. It is about who gets to cross the threshold of a place of worship, and on what terms.  There is, however, an encouraging aspect to the story. Judges are proving to be the strongest line of defense. The Benedictine community—the lawful guardian of the basilica—turned to the courts, and its legal challenge is likely, in practical terms, to bring the project to a halt.   Even as ideological figures push forward, the rule of law is still taken seriously in Spanish courtrooms, where a religious community can still ask a judge whether the state has the right to force its way into a place of worship and receive an impartial hearing. The separation of powers is not a slogan here. At this very moment, it is the only barrier standing between this basilica and the plans that have been drawn up for its interior.  Strip away the noise and the propaganda, and the question becomes simple—one that concerns everyone, believer and nonbeliever alike: How far may public power go inside the doors of a place of worship?  Americans answered that question long ago, and they placed the answer first in the Bill of Rights. It is no accident that the First Amendment begins with the free exercise of religion. The Founders understood that religious liberty is the cornerstone that supports every other freedom. A state that can force its way into a church and ration the sacred can, in time, force its way into anything—your speech, your associations, your conscience.  For that reason, defending the threshold of a basilica in Spain means defending something far greater than a single house of worship or a single faith. It means defending the first freedom, the one upon which all the others depend, and the very idea of liberty that has stood at the heart of the Western democratic tradition. For now, Spain’s courts are carrying that defense forward. They deserve the attention—and the solidarity—of everyone who still believes that freedom begins precisely where the state agrees to stop.  We publish a variety of perspectives.
