Evangelii Gaudium §108

108. As I mentioned above, I have not sought to offer a complete diagnosis, but I invite communities to complete and enrich these perspectives on the basis of their awareness of the challenges facing them and their neighbours. It is my hope that, in doing so, they will realize that whenever we attempt to read the signs of the times it is helpful to listen to young people and the elderly. Both represent a source of hope for every people. The elderly bring with them memory and the wisdom of experience, which warns us not to foolishly repeat our past mistakes. Young people call us to renewed and expansive hope, for they represent new directions for humanity and open us up to the future, lest we cling to a nostalgia for structures and customs which are no longer life-giving in today’s world.
