Catholics are free to take part in politics, i.e. matters relating to the system of government and the administration of what concerns the public welfare. Moreover, it is their duty to interest themselves in the affairs of the community, because (1) every individual is a social being with social obligations and duties to fellow citizens and to the State, and (2) adults have the responsibility of the vote, which must be exercised according to an enlightened conscience. Hence, every adult must interest himself in the affairs of his country, both in its internal government and in its external relations with other States.
A Catholic may be a member of a political party, provided the party does not definitely take its stand on non-Christian principles. The party must not have a non-Christian basis or constitution. This is a necessary condition. Furthermore, a Catholic may only give support and allegiance to his party in so far as its proposals are in keeping with Christian principles. To a party which has a program which is only partly in accord with Christian principles, the Catholic may only give his allegiance with certain limitations. Parties are often influenced by outside affiliations and agencies that affect and may even dictate its policy, sometimes in defiance of Natural and Divine Law. A Catholic must exercise the right to differ from, and even oppose, his party when it advocates measures that violate the Natural and Divine Law. On questions of morality, the Catholic must take his guidance, not from a political party, but from the teaching of the Church, divinely instituted for this purpose, and infallible. In the event of conflict between the Catholic's conscience and the demands of his political party, he must obey his Catholic conscience and withstand the demands of his party. "We must obey God rather than men." (Acts 5:29)
No Catholic can be a Socialist or Communist, in the true sense of the term, without ceasing to be a Catholic. A Socialist or Communist is one who identifies himself with the Socialist creed and principles regarding man's nature, origin, and destiny, and the functions of the family and the State. As Pope Pius XI writes: "No one can be at the same time a good Catholic and a true Socialist." (Quadragesimo Anno, §120) The basic principles of Socialism and Communism are condemned by the Church. No Catholic can accept them and remain a Catholic.
The Church condemns Communism and Socialism, not merely because it denies private property and urges class war, but also because of its teaching in theory and practice regarding God, religion, morality, Marriage, education, and many other truths.
