I don't agree that "Centesimus Annus" endorses a "market economy" ideology. In particular, due also to the specific historical moment (1991), Joan Paul II was critical of the collectivistic economy, but the central issues of common good and the ethics of virtues are not consistent with the main theoretical element of a market economy, that is the common good as unintended consequence of people acting for individual self-interest. Furthermore, Benedict XVI with his "Deus Charitas est" claims a central role of the State intervention in the economy, and is quite critical of the free market economy. In general the catholic social thought is not against the market (being the market economy an "invention" of the Christianitas), but it does not endorse any particular ideology (included liberalism), although people like Micheal Novak think that this link between Christianity and liberalism actually exists. Novak, however, does not represent the thought of the Church, nor is the mainstream among catholic economists and social scientists (at least in Europe). Luigino Bruni
