Populorum Progressio §46
Populorum Progressio: On the Development of Peoples
46 Anxious appeals for help have already been voiced. That of Our predecessor John XXIII was warmly received. (49) We reiterated his sentiments in Our Christmas message of 1963, (50) and again in 1966 on behalf of India. (51) The work of the Food and Agriculture Organization of the United Nations (FAO) has been encouraged by the Holy See and has found generous support. Our own organization, Caritas Internationalis , is at work all over the world. Many Catholics, at the urging of Our brother bishops, have contributed unstintingly to the assistance of the needy and have gradually widened the circle of those they call neighbors.
