When you consider that one of Pope Benedict's encyclicals stated that (and I quote)
I think you can understand the worry.In the face of the unrelenting growth of global interdependence, there is a strongly felt need, even in the midst of a global recession, for a reform of the United Nations Organization, and likewise of economic institutions and international finance, so that the concept of the family of nations can acquire real teeth.
-- Paragraph 67 of Caritas in Veritate, from the thread Encycli-bites for reading Caritas in veritate
