On May 11, 2007, when Benedict XVI opened the Fifth General Assembly of CELAM in Aparecida, he re-proposed the message of his predecessor Paul VI, who in Easter from 1967 published the encyclical Populorum progressio on the development of peoples with two strong ideas, which soon became two slogans more repeated than put into practice: "the social question is now global" and "development is the new name for peace". Dust has not accumulated on the cover of Populorum Progressio, it has not been lost in the corners of our libraries, it is not forgotten ... In his longing and commitment to peace and fraternal charity, in his pastoral and apostolic passion our Holy Father Benedict XVI follows in the footsteps of his predecessor Paul VI.
In this Italian book, Populorum progressio tra ricordi e speranze (Cantagalli, 2007), Card. Paul Poupard speaks of his memories of Pope Paul VI, of the birth of Populorum Progressio and of its relevance today, in a changed cultural and social context.
