The Catholic Church's Teaching on Immigration

The Catholic Church recognizes both a natural right to migrate and the legitimate authority of governments to defend their borders, indicating a need to strike a balance between these two rights. The Church's teachings reject extremes such as open borders or the complete restriction of migration, advocating instead for humane and just treatment of migrants. For instance, historical examples demonstrate the consequences of closed borders, such as the MS St. Louis tragedy, where refugees faced dire outcomes because of strict immigration policies. Additionally, the Church emphasizes the preferential option for the poor, asserting that wealthier nations have a moral obligation to assist those in need while also acknowledging limitations to immigration to safeguard the well-being of the host country.
