Young migrants experience separation from their place of origin and often a cultural and religious uprooting as well. Fragmentation is also felt by the communities they leave behind, which lose their most vigorous and enterprising elements, and by the families, especially when one or both of the parents migrates, leaving the children in the country of origin. The Church has an important role as a point of reference for the young members of these divided families. But the stories of migrants are also stories of encounter between persons and between cultures: for the communities and societies where they arrive, they bring an opportunity for enrichment and the integral human development of all. Initiatives of welcome involving the Church have an important role from this perspective and they can bring new life to the communities capable of adopting them.
