Evangelii Nuntiandi §31

31. Between evangelization and human advancement- development and liberation- there are in fact profound links. These include links of an anthropological order, because the man who is to be evangelized is not an abstract being but is subject to social and economic questions. They also include links in the theological order, since one cannot dissociate the plan of creation from the plan of Redemption. The latter plan touches the very concrete situations of injustice to be combated and of justice to be restored. They include links of the eminently evangelical order, which is that of charity: how in fact can one proclaim the new commandment without promoting in justice and in peace the true, authentic advancement of man? We ourself have taken care to point this out, by recalling that it is impossible to accept "that in evangelization one could or should ignore the importance of the problems so much discussed today, concerning justice, liberation, development and peace in the world. This would be to forget the lesson which comes to us from the Gospel concerning love of our neighbor who is suffering and in need."[61]

The same voices which during the Synod touched on this burning theme with zeal, intelligence and courage have, to our great joy, furnished the enlightening principles for a proper understanding of the importance and profound meaning of liberation, such as it was proclaimed and achieved by Jesus of Nazareth and such as it is preached by the Church.
