Populorum Progressio §5

⁵ Even more recently, We sought to fulfill the wishes of the Council and to demonstrate the Holy See's concern for the developing nations. To do this, We felt it was necessary to add another pontifical commission to the Church's central administration . The purpose of this commission is "to awaken in the People of God full awareness of their mission today. In this way they can further the progress of poorer nations and international social justice, as well as help less developed nations to contribute to their own development." (8) The name of this commission, Justice and Peace, aptly describes its program and its goal. We are sure that all men of good will want to join Our fellow Catholics and fellow Christians in carrying out this program. So today We earnestly urge all men to pool their ideas and their activities for man's complete development and the development of all mankind.
