From BBC News: "The Pope has called for reform of the United Nations and financial bodies, giving them the "real teeth" needed to tackle economic and social injustice. Benedict XVI said the blind pursuit of profit and economic mismanagement had "wreaked havoc" on the global economy. The market, said the Pope, must not become the place where the strong prevail over the weak. His encyclical letter said a reformed UN should strive for disarmament, food security and environmental protection. An encyclical letter is the highest form of papal teaching, says the BBC's David Willey in Rome. This letter, Caritas in Veritate, or Charity in Truth, is his third since being made Pope in 2005. It is the first to focus on social issues, and follows two on spiritual matters." - Mark Trapp from Bookmarklet
