No, the Church has not. The Church has rejected socialism, not socialism as redefined willy-nilly by anyone that comes along. Words have real, concrete meanings in Church documents.
The popes did not limit socialism to total government control over the economy and businesses. They recognized it also as a theory of society and as the welfare state.
Pope Leo XII,Rerum Novarum:
“Man’s needs do not die out, but forever recur; although satisfied today, they demand fresh supplies for tomorrow. Nature accordingly must have given to man a source that is stable and remaining always with him, from which he might look to draw continual supplies. And this stable condition of things he finds solely in the earth and its fruits. There is no need to bring in the State. Man precedes the State, and possesses, prior to the formation of any State, the right of providing for the substance of his body.”
“At the present day many there are who, like the heathen of old, seek to blame and condemn the Church for such eminent charity. They would substitute in its stead a system of relief organized by the State. But no human expedients will ever make up for the devotedness and self sacrifice of Christian charity. Charity, as a virtue, pertains to the Church.”
PIUS XI (1922-1939):
We make this pronouncement: Whether considered as a doctrine, or an historical fact, or a movement, Socialism, if it remains truly Socialism, even after it has yielded to truth and justice on the points which we have mentioned, cannot be reconciled with the teachings of the Catholic Church because its concept of society itself is utterly foreign to Christian truth.”
(Encyclical Quadragesimo Anno, May 15, 1931, n. 117)
JOHN XXIII (1958-1963):
“Pope Pius XI further emphasized the fundamental opposition between Communism and Christianity, and made it clear that no Catholic could subscribe even to moderate Socialism. The reason is that Socialism is founded on a doctrine of human society which is bounded by time and takes no account of any objective other than that of material well-being. Since, therefore, it proposes a form of social organization which aims solely at production, it places too severe a restraint on human liberty, at the same time flouting the true notion of social authority.” (Encyclical Mater et Magistra, May 15, 1961, n. 34)
Pope John Paul 2,Centesimus Annus,1991:
“In recent years the range of such intervention has vastly expanded, to the point of creating a new type of state, the so-called ‘Welfare State.’ This has happened in some countries in order to respond better to many needs and demands by remedying forms of poverty and deprivation unworthy of the human person. However, excesses and abuses, especially in recent years, have provoke very harsh criticisms of the Welfare State, dubbed the ‘Social Assistance State.’ Malfunctions and defects in the Social Assistance State are the result of an inadequate understanding of the tasks proper to the State. Here again the principle of subsidiarity must be respected: a community of a higher order should not interfere in the internal life of a community of a lower order, depriving the latter of its functions, but rather should support it in case of need and help to coordinate its activity with the activities of the rest of society, always with a view to the common good. “By intervening directly and depriving society of its responsibility, the Social Assistance State leads to a loss of human energies and an inordinate increase of public agencies, which are dominated more by bureaucratic thinking than by concern for serving their clients, and which are accompanied by an enormous increase in spending, In fact, it would appear that needs are best understood and satisfied by people who are closest to them who act as neighbors to those in need. It should be added that certain kinds of demands often call for a response which is not simply material but which is capable of perceiving the deeper human need.”
May I remind you that it is the Church that is stepping up and helping these people, or did you even read the topic of this thread before you started posting?
