Imported from the USSR, the communist ideology justified the assault against civil society, against political and economic pluralism; it justified the annihilation of the democratic parties, the destruction of the free market, extermination by assassination, deportations, forced labor, and the imprisonment of hundreds of thousands of people. Behind the mask of "socialist humanism" lay concealed the most profound contempt for human beings as individuals.

From the outset in 1917, the Communists believed in a utopian ideology, extreme, organised violence, atheism, a redefined place of the individual that served to reject Enlightenment precepts, and the rejection of preceding Russian history. During the Civil War and the 1920s, the Orthodox Church was crushed, with the slaughter of tens of thousands of priests and monks, and the desecration and destruction of churches, monasteries and the tombs of saints. The real and spiritual landscapes of Russia and the psychological life of the people were transformed as a consequence. Communism in its own way therefore constituted a major civilisational challenge to the notion in Europe and North America of a 'Western Civilisation', whether or not articulated explicitly in this fashion. This civilisation owed much to Christianity and placed considerable weight on liberalism and toleration. From this perspective, Communism, drawing both on a reconceptualisation of Russian authoritarianism and on a new, totalitarian ideology and practice, posed a counter-civilisational challenge with its own precepts, aims, methods and anticipated outcomes.

The theory of Communism may be summed up in the single sentence: Abolition of private property.

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?

the theory of Communists may be summed up in the single sentence: Abolition of private property.

(…) I disagree with the commonly accepted opinion that real communism would be the realization of Marxist ideals and that it would be imposed on the masses, against their will, their desires and their interests, by a handful of people. ideologues resorting to force and lies. Communism is not only a political regime that can be transformed by an order from above, it is a social organization of the population. A Soviet Union was formed, not in accordance with the Marxist project nor at the whim of Marxist ideologues, but by virtue of the objective laws which govern the organization of a large mass of population into a completed social organism. It is the result of a historical creative process in which millions of people took part. (…) p. 13

It is significant that Communist theory treats the proletariat as though it were a unique branch of the human race. The proletariat is assumed to be a special breed which would almost automatically blossom into pleasant, efficient social-economic living if it could just be liberated from oppressive government. The government is presumed to be nothing more than the tool of an oppressive class of capitalists and consequently, if the capitalist class were destroyed, the need for any kind of government would be obliterated. The Communist leaders have always felt confident that when the proletariat takes over it will not want to oppress anyone and therefore the need for government will be nonexistent.

First, Communism is based on a materialistic and humanistic view of life and history. According to Communist theory, matter, not mind or spirit, speaks the last word in the universe. Such a philosophy is avowedly secularistic and atheistic. Under it, God is merely a figment of the imagination, religion is a product of fear and ignorance, and the church is an invention of the rulers to control the masses. Moreover, Communism, like humanism, thrives on the grand illusion that man, unaided by any divine power, can save himself and usher in a new society.... Cold atheism wrapped in the garments of materialism, Communism provides no place for God or Christ.

Communism, in a word, is the organization of millions of people into a whole, according to community laws. This naturally implies the establishment of many things that did not exist in the previous non-communist society, or in society of another type. The pre-existing community elements, the beginnings of communism, are transformed in the newly created conditions, sometimes so radically that they no longer seem to have any connection with their former manifestations. Hence the erroneous impression that communist-type relations are absolutely new. p. 14-16

Communism differs from all previous movements in that it overturns the basis of all earlier relations of production and intercourse, and for the first time consciously treats all natural premises as the creatures of hitherto existing men, strips them of their natural character and subjugates them to the power of the united individuals. Its organisation is, therefore, essentially economic, the material production of the conditions of this unity; it turns existing conditions into conditions of unity. The reality, which communism is creating, is precisely the true basis for rendering it impossible that anything should exist independently of individuals, insofar as reality is only a product of the preceding intercourse of individuals themselves.

Second, Communism is based on ethical relativism and accepts no stable moral absolutes. Right and wrong are relative to the most expedient methods for dealing with class war. Communism exploits the dreadful philosophy that the end justifies the means. It enunciates movingly the theory of a classless society, but alas! its methods for achieving this noble end are all too often ignoble. Lying, violence, murder, and torture are considered to be justifiable means to achieve the millennial end. Is this an unfair indictment? Listen to the words of Lenin, the real tactician of Communist theory: ‘We must be ready to employ trickery, deceit, lawbreaking, withholding and concealing truth.’ Modem history has known many tortuous nights and horror-filled days because his followers have taken this statement serious.

"Communism has never concealed the fact that it rejects all absolute concepts of morality. It scoffs at any consideration of "good" and "evil" as indisputable categories. Communism considers morality to be relative, to be a class matter. Depending on circumstances and the political situation, any act, including murder, even the killing of hundreds of thousands, could be good or could be bad. It all depends on class ideology. And who defines this ideology? The whole class cannot get together to pass judgment. A handful of people determine what is good and what is bad. But I must say that in this respect Communism has been most successful. It has infected the whole world with the belief in the relativity of good and evil. Today, many people apart from the Communists are carried away by this idea."

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.

Third, Communism attributes ultimate value to the state. Man is made for the state and not the state for man. One may object, saying that in Communist theory the state is an ‘interim reality,’ which will ‘wither away’ when the classless society emerges. True--in theory; but it is also true that, while it lasts, the state is the end. Man is a means to that end. Man has no inalienable rights. His only rights are derived from, and conferred by, the state. Under such a system, the fountain of freedom runs dry. Restricted are man's liberties of press and assembly, his freedom to vote, and his freedom to listen and to read. Art, religion, education, music, and science come under the gripping yoke of government control. Man must be a dutiful servant to the omnipotent state.
