Divini Redemptoris §10

¹⁰ Communism, moreover, strips man of his liberty, robs human personality of all its dignity, and removes all the moral restraints that check the eruptions of blind impulse. There is no recognition of any right of the individual in his relations to the collectivity; no natural right is accorded to human personality, which is a mere cog-wheel in the Communist system. In man's relations with other individuals, besides, Communists hold the principle of absolute equality, rejecting all hierarchy and divinely-constituted authority, including the authority of parents. What men call authority and subordination is derived from the community as its first and only font. Nor is the individual granted any property rights over material goods or the means of production, for inasmuch as these are the source of further wealth, their possession would give one man power over another. Precisely on this score, all forms of private property must be eradicated, for they are at the origin of all economic enslavement .
