Communism is a hateful thing and a menace to peace and organized government; but the communism of combined wealth and capital, the outgrowth of overweening cupidity and selfishness, which insidiously undermines the justice and integrity of free institutions, is not less dangerous than the communism of oppressed poverty and toil, which, exasperated by injustice and discontent, attacks with wild disorder the citadel of rule. He mocks the people who proposes that the Government shall protect the rich and that they in turn will care for the laboring poor. Any intermediary between the people and their Government or the least delegation of the care and protection the Government owes to the humblest citizen in the land makes the boast of free institutions a glittering delusion and the pretended boon of American citizenship a shameless imposition.

Communism is a form of organized crime justified by the [worldview] of Marxism–Leninism. It is basically a combination of criminal inclination coupled with uncontrolled political power. Like all crime, communism is parasitic. It produces nothing of value itself; it must rely on force, propaganda, torture, intimidation, threats, and espionage to survive. Like cancer, communism consumes its host. Except that in communism’s case, it will only die when the whole planet is consumed. Must we let things get to that point?

Communism is evil. Its driving forces are the deadly sins of envy and hatred.

The positions communism as a threat because communism names the defeat of and alternative to capitalism. It recognizes the crisis in capitalism: over-accumulation leaves the rich sitting on piles of cash they can't invest; industrial capacity remains unused and workers unemployed; global interconnections make unneeded skyscrapers, fiber-optic cables, malls, and housing developments as much a part of China as the US. At the same time, scores of significant problems – whether food shortages linked to climate change, energy shortages resulting from oil dependency, or drug shortages resulting from the failure of private pharmaceutical companies to risk their own capital – remain unmet because they require the kinds of large-scale planning and cooperation that capitalism, particularly in its contemporary finance and communications-driven incarnation, subverts.

The reason that communism is the greatest evil is simple: Communism is the greatest enemy of personal responsibility ever invented. Communism waters down and diminishes personal accomplishments. Once one sees this clearly, seemingly inexplicable communist-driven policies make sense. Every communist policy—from the minimum wage to single-payer health care to rent control—is designed to minimize and thwart personal responsibility. Conversely, individuals who take personal responsibility become leaders, inspiring others to take control of their own lives. Individuals who take personal responsibility for their actions are accountable for their behavior, which results in better relationships with others.

Communism is the death of the soul. It is the organization of total conformity — in short, of tyranny — and it is committed to making tyranny universal.

Sin must be called by its name. Communism is one of the most dangerous sins in the world today. Every gospel that does not denounce it is not the pure gospel. The Underground Church denounces it, risking liberty and life. The less have we to be silent in the West.

Communism is the corruption of a dream of justice.

Communism teaches and seeks two objectives: Unrelenting class warfare and absolute extermination of private ownership. Not secretly or by hidden methods does it do this, but publicly, openly, and by employing every and all means, even the most violent. To achieve these objectives there is nothing which it does not dare, nothing for which it has respect or reverence; and when it has come to power, it is incredible and portentlike in its cruelty and inhumanity. The horrible slaughter and destruction through which it has laid waste vast regions of eastern Europe and Asia are the evidence; how much an enemy and how openly hostile it is to Holy Church and to God Himself is, alas, too well proved by facts and fully known to all. Although We, therefore, deem it superfluous to warn upright and faithful children of the Church regarding the impious and iniquitous character of Communism, yet We cannot without deep sorrow contemplate the heedlessness of those who apparently make light of these impending dangers, and with sluggish inertia allow the widespread propagation of doctrine which seeks by violence and slaughter to destroy society altogether. All the more gravely to be condemned is the folly of those who neglect to remove or change the conditions that inflame the minds of peoples, and pave the way for the overthrow and destruction of society.

The most dangerous Communism [...] is the wolf in sheep's clothing of conservatism who bent upon preserving the policies of greed.

The menace of communism in this country will remain a menace until the American people make themselves aware of the techniques of communism. No one who truly understands what it really is can be taken in by it. Yet the individual is handicapped by coming face to face with a conspiracy so monstrous he cannot believe it exists. The American mind simply has not come to a realization of the evil which has been introduced into our midst. It rejects even the assumption that human creatures could espouse a philosophy which must ultimately destroy all that is good and decent.

The trouble with Communism is that it has neither a theology nor a Christology; therefore it emerges with a mixed-up anthropology. Confused about God, it is also confused about man. In spite of its glowing talk about the welfare of the masses, Communism's methods and philosophy strip man of his dignity and worth, leaving him as little more than a depersonalized cog in the ever-turning wheel of the state.

The cause of Communism is the greatest cause in the history of mankind becasuse it seeks to remove from society all forms of oppression and exploitation, to liberate mankind and to ensure peace and prosperity to all.

Many Liberals who voted Conservative at the last General Election thought the country was in danger from Communism. But the greatest danger from Communism is that we should mismanage our affairs and that we will end in bankruptcy. I am not afraid of Communist orators or leaflets. I am not even afraid of the Russian subsidies to them; but I am afraid of such a muddle of our affairs that the working classes in despair will take anything.
