The Universal Church has not always been a strong supporter of globalisation and certainly not of free trade. In 1967, for example, Pope Paul VI published Populorum progressio. This was a major encyclical on human development which inspired the creation of Cafod and many other charitable organisations. The document was highly critical of free trade, suggesting that it might only work between countries that are roughly equal economically. It argued for price support schemes and for the protection of infant industries.
