“That infamous doctrine of so-called Communism, which is absolutely contrary to the natural law itself,” the pope warned, “would utterly destroy the rights, property and possessions of all men, and even society itself.”
The statement represents the first papal condemnation of communism. Meanwhile, just 730 miles from Vatican City, a young German intellectual was in Brussels, crafting an entirely different vision—one that sought to overturn the social, political, and religious order.
“Workers of the world, unite! You have nothing to lose but your chains!” Karl Marx wrote in “The Communist Manifesto,” published just two years later. “The history of all hitherto existing society is the history of class struggles.”
Gulags, Political Terror, and Mass Famines
Marxism became the state dogma in the USSR and remained so following Lenin’s death in 1924. During the 20th century, under regimes such as Stalin’s Soviet Union, Mao’s China, and Pol Pot’s Cambodia, the pursuit of a classless society resulted in mass repression, forced collectivization, and bloody purges.Pius IX had warned his “venerable brethren” of the radical socialists, likening them to “ravening wolves” disguised in sheep’s clothing. He was proven right in the immediate aftermath of Lenin’s takeover.
In “The Gulag Archipelago,” Aleksandr Solzhenitsyn recalled that the tsars did not use torture, but Marxists saw its utility and embraced it without hesitation.
“Torture was considered an essential and natural method of investigation,” wrote Solzhenitsyn, who was sent to a gulag in 1945 after officials intercepted his private letter critical of Stalin.
Lenin’s use of terror cost him support from some socialists abroad—Rosa Luxemburg famously wrote that a proletarian revolution “hates and abominates murder.” But terror enabled him to consolidate control over the revolutionary state, and Joseph Stalin, his successor, would adopt and vastly expand these methods.
Under Stalin, secret police, gulags, and show trials were used to crush political dissent. With the population subdued, socialism’s hour had arrived—but at a catastrophic human cost. In the late 1920s and 1930s, tens of millions were forced into collectivized farming. The results were horrifying.
‘A Dark Design’
Most people today are familiar with some of the horrors of communism, although the West never fully grasped the evils that it unleashed, nor has it sought to educate its rising generations on the monstrosity of communism. What’s astonishing is that Pope Pius IX seemed to foresee those horrors nearly 70 years before they were implemented at scale.With remarkable clarity, Pius IX warned of the “dark design” of communists, who cloaked their ideology in appeals to noble Christian sentiments—including love for the poor—to gain power and moral legitimacy.
“Once they have ensnared the people with this false appearance of virtue, and have completely won them over by trickery, they spew forth the poison of their doctrines and plunge their captives into every kind of crime and wickedness,” the Pope wrote. “After taking their captives gently, they mildly bind them, and then kill them in secret.”
“If ever it seemed as if man held a crystal ball,” Kengor wrote of “Qui Pluribus,” “few statements were so unerringly predictive of what was to come.”
When Pius refers to communism as a “dark design” that would make men “fly in terror,” it’s difficult not to think of religious persecution in the USSR.
Pius’s foresight proved uncanny because he recognized the moral and spiritual deception at the heart of communism. He understood that it was not merely an economic threat, but a spiritual one designed to overturn the moral order.
“Communism abolishes eternal truths, it abolishes all religion, and all morality,” Marx wrote approvingly in his manifesto, “instead of constituting them on a new basis; it therefore acts in contradiction to all past historical experience.”
To “establish the truth of this world,” man must reject not just God but all conventions, traditions, and morals.
This is precisely what Lenin did.
Soviet authorities banned religious education for children and encouraged them to denounce their parents if they showed signs of ideological wavering. In place of traditional morality, Lenin established “communist morality.”
“We say,” said Lenin, “morality is what serves to destroy the old and exploiting society and to unite all the working people around the proletariat, which is building up a new communist society.”
A Historic Pope
Pius IX was not the only pope to warn against the dangers of communism and socialism. From Leo XIII to Pius XII and beyond, his successors issued clear and forceful denunciations of the ideology. But Pius IX’s vivid language and early foresight set him apart. He condemned communism not merely as a flawed economic theory, but as a moral poison masquerading as virtue. This ideology threatened to corrupt souls and unravel the social order at the core of Western civilization.His warnings, penned decades before the Bolshevik Revolution while Karl Marx was still drafting his dark catechism, today read like a prophetic indictment of the bloodiest creed in human history.
