For every quote I find I, too, can find an opposing quote. Particularly from the USCCB.
But the fact of the matter is that the papal magisterium (the official teaching of the Church) does not, in any way, support socialism. Period. I would run through a whole list of quotes from every pope from Leo XII through Benedict XVI (the current pope has not yet made any Magisterial statements as of yet)
One of my favorites, by the way, is from John XXIII:
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 (34), 1961
One other thing, on the topic of He isn’t anti-Catholic at all. His ministrations are designed to encourage Catholics to defect from the Faith. In my book, that is "anti-Catholic." Anti = opposed to.
Of course he is against the Catholic faith, he is a born-from-above Christian. He has been gloriously saved. As such he has tremendous concern for Roman Catholic people, and rightly so.
