Somehow this discussion wandered into a debate over idolatry. This post concerns communism (and idolatry as it relates to money and the State). You can get the main idea by just reading the sentences I put in bold type.
Catechism of the Catholic Church
2402 In the beginning God entrusted the earth and its resources to the common stewardship of mankind to take care of them, master them by labor, and enjoy their fruits.187 The goods of creation are destined for the whole human race. However, the earth is divided up among men to assure the security of their lives, endangered by poverty and threatened by violence. The appropriation of property is legitimate for guaranteeing the freedom and dignity of persons and for helping each of them to meet his basic needs and the needs of those in his charge. It should allow for a natural solidarity to develop between men.
2403 The right to private property, acquired or received in a just way, does not do away with the original gift of the earth to the whole of mankind. The universal destination of goods remains primordial, even if the promotion of the common good requires respect for the right to private property and its exercise.
2404 "In his use of things man should regard the external goods he legitimately owns not merely as exclusive to himself but common to others also, in the sense that they can benefit others as well as himself."188 The ownership of any property makes its holder a steward of Providence, with the task of making it fruitful and communicating its benefits to others, first of all his family.
2405 Goods of production - material or immaterial - such as land, factories, practical or artistic skills, oblige their possessors to employ them in ways that will benefit the greatest number. Those who hold goods for use and consumption should use them with moderation, reserving the better part for guests, for the sick and the poor.
2406 Political authority has the right and duty to regulate the legitimate exercise of the right to ownership for the sake of the common good.
The Catechism is not set in stone. It may change in response to a changing world. Social doctrine came about in response to the de-humanizing effect of Industrial Revolution. The main points to be taken from above are that:
a) there is an important role for political authority to play.
b) private property must be respected under the law, but in reality we are not owners, but stewards of property on the earth (which also belongs to future generations) and so we should be charitable to others and to the poor and use resources with moderation.
c) Government should not be so weighty and controlling that it asphyxiates a natural solidarity to develop between men.
The following entries come under the heading Social Doctrine of the Church:
2424 A theory that makes profit the exclusive norm and ultimate end of economic activity is morally unacceptable. The disordered desire for money cannot but produce perverse effects. It is one of the causes of the many conflicts which disturb the social order.
A system that "subordinates the basic rights of individuals and of groups to the collective organization of production" is contrary to human dignity. Every practice that reduces persons to nothing more than a means of profit enslaves man, leads to idolizing money, and contributes to the spread of atheism. "You cannot serve God and mammon."
2425 The Church has rejected the totalitarian and atheistic ideologies associated in modem times with "communism" or "socialism." She has likewise refused to accept, in the practice of "capitalism," individualism and the absolute primacy of the law of the marketplace over human labor.207 Regulating the economy solely by centralized planning perverts the basis of social bonds; regulating it solely by the law of the marketplace fails social justice, for "there are many human needs which cannot be satisfied by the market."208 Reasonable regulation of the marketplace and economic initiatives, in keeping with a just hierarchy of values and a view to the common good, is to be commended.

I see in these entries a clear distinction between the Catholic Church and those megachurch preachers who claim that you'll get rich if you pray hard enough (or send them 'seed money'). The idolization of money, in fact, leads to atheism. Equally, the idolization of the State leads to atheism. Both unfettered capitalism and communism pervert the natural development of social bonds. If you read Upton Sinclair's The Jungle, you catch a glimpse of the de-humanizing and family destroying effects of a capitalist society whose only values are material wealth, utility and power. If you read George Orwell's 1984, you catch a glimpse of a dystopian Totalitarian State where, similarly, the values of utility and power supplant our better ideals.
Clearly, the Church promotes a middle ground. My response, as a libertarian would be the following...
In a simple sermon many many centuries ago, Augustine said, "The City of God is built with a temporary scaffolding". Government, machina temporalis, is a temporary necessity. At some point, the scaffolding is removed. Indeed, the end game of Christianity is a harmonious anarchy, where justice is written upon the hearts of man. Are we there yet? Perhaps not. Man is not yet man.
What the Church needs to address in a future Catechism is the emergence of bio-engineering. Are we to attempt to write our own destiny by fiddling with the genes of humankind? Or, are we to trust in Providence guiding over natural selection to reach our destiny as a species?
