I encourage you to welcome refugees into your homes and communities, so that their first experience of Europe is not the traumatic experience of slee… - Pope Francis

At the same time, new difficulties are constantly surfacing: experiences of failure and the human weaknesses which bring so much pain. We all know from experience that sometimes a task does not bring the satisfaction we seek, results are few and changes are slow, and we are tempted to grow weary. Yet lowering our arms momentarily out of weariness is not the same as lowering them for good, overcome by chronic discontent and by a listlessness that parches the soul. It also happens that our hearts can tire of the struggle because in the end we are caught up in ourselves, in a careerism which thirsts for recognition, applause, rewards and status. In this case we do not lower our arms, but we no longer grasp what we seek, the resurrection is not there. In cases like these, the Gospel, the most beautiful message that this world can offer, is buried under a pile of excuses.

The human heart desires joy. We all desire joy, every family, every people aspires to happiness. But what is the joy that the Christian is called to live out and bear witness to? It is the joy that comes from the closeness of God, from his presence in our life. From the moment Jesus entered into history, with his birth in Bethlehem, humanity received the seed of the Kingdom of God, like the soil receives the seed, the promise of a future harvest.

It is difficult to make a general judgement about genetic modification (GM), whether vegetable or animal, medical or agricultural, since these vary greatly among themselves and call for specific considerations. The risks involved are not always due to the techniques used, but rather to their improper or excessive application. Genetic mutations, in fact, have often been, and continue to be, caused by nature itself. Nor are mutations caused by human intervention a modern phenomenon. The domestication of animals, the crossbreeding of species and other older and universally accepted practices can be mentioned as examples. We need but recall that scientific developments in GM cereals began with the observation of natural bacteria which spontaneously modified plant genomes. In nature, however, this process is slow and cannot be compared to the fast pace induced by contemporary technological advances, even when the latter build upon several centuries of scientific progress.
