You will not be able to set up in a pagan or an heretical or a wholly indifferent society the institutions characteristic of economic freedom; you will not be able to curb competition which alone would be sufficient to destroy such freedom, nor pursue permanently and consecutively any one part of the program. The thing must be done as a whole, and it can be done as a whole only by the ambient influence of Catholicism."
