"The presence of brothers and sisters from different cultures should be celebrated as a gift to the Church."Welcoming the Stranger Among Us: Unity in Diversity,
A Statement of the US Catholic Bishops
The Gospel mandate to “welcome the stranger” requires Catholics to care for and stand with immigrants, both documented and undocumented, including immigrant children. Comprehensive reform is urgently necessary to fix a broken immigration system and should include a temporary work program with worker protections and a path to permanent residency; family reunification policies; a broad and fair legalization program; access to legal protections, including due process and essential public programs; refuge for those feeling persecutions and exploitation; and policies to address the root causes of migration. The right and responsibility of nations to control their borders and to maintain the rule of law should be recognized. Forming Consciences for Faithful Citizenship, 2007, 83
The principle of solidarity, also articulated in terms of "friendship" or "social charity," is a direct demand of human and Christian brotherhood…Solidarity is manifested in the first place by the distribution of goods and remuneration for work. It also presupposes the effort for a more just social order where tensions are better able to be reduced and conflicts more readily settled by negotiation. Socio-economic problems can be resolved only with the help of all the forms of solidarity: solidarity of the poor among themselves, between rich and poor, of workers among themselves, between employers and employees in a business, solidarity among nations and peoples. International solidarity is a requirement of the moral order; world peace depends in part upon this. The virtue of solidarity goes beyond material goods. In spreading the spiritual goods of the faith, the Church has promoted, and often opened new paths for, the development of temporal goods as well. Catechism of the Catholic Church, 1939-1942.
