From Pope Benedict XVI’s encyclical Caritas in Veritate (2009):
Economic activity cannot solve all social problems through the simple application of commercial logic. This needs to be directed towards the pursuit of the common good, for which the political community in particular must also take responsibility. Therefore, it must be borne in mind that grave imbalances are produced when economic action, conceived merely as an engine for wealth creation, is detached from political action, conceived as a means for pursuing justice through redistribution.
The Church has always held that economic action is not to be regarded as something opposed to society. In and of itself, the market is not, and must not become, the place where the strong subdue the weak. Society does not have to protect itself from the market, as if the development of the latter were ipso facto to entail the death of authentically human relations. Admittedly, the market can be a negative force, not because it is so by nature, but because a certain ideology can make it so. It must be remembered that the market does not exist in the pure state. It is shaped by the cultural configurations which define it and give it direction. Economy and finance, as instruments, can be used badly when those at the helm are motivated by purely selfish ends. Instruments that are good in themselves can thereby be transformed into harmful ones. But it is man’s darkened reason that produces these consequences, not the instrument per se. Therefore it is not the instrument that must be called to account, but individuals, their moral conscience and their personal and social responsibility.
The Church’s social doctrine holds that authentically human social relationships of friendship, solidarity and reciprocity can also be conducted within economic activity, and not only outside it or “after” it. The economic sphere is neither ethically neutral, nor inherently inhuman and opposed to society. It is part and parcel of human activity and precisely because it is human, it must be structured and governed in an ethical manner.
The great challenge before us, accentuated by the problems of development in this global era and made even more urgent by the economic and financial crisis, is to demonstrate, in thinking and behaviour, not only that traditional principles of social ethics like transparency, honesty and responsibility cannot be ignored or attenuated, but also that in commercial relationships the principle of gratuitousness and the logic of gift as an expression of fraternity can and must find their place within normal economic activity. This is a human demand at the present time, but it is also demanded by economic logic. It is a demand both of charity and of truth.
