Migration in the Light of Catholic Social Teaching (excerpt from "Strangers No Longer: Together on the Journey of Hope, A Pastoral Letter Concerning Migration from the Catholic Bishops of Mexico and the United States")
Catholic teaching has a long and rich tradition in defending the right to migrate. Based on the life and teachings of Jesus, the Church's teaching has provided the basis for the development of basic principles regarding the right to migrate for those attempting to exercise their God-given human rights. Catholic teaching also states that the root causes of migration — poverty, injustice, religious intolerance, armed conflicts — must be addressed so that migrants can remain in their homeland and support their families.
In modern times, this teaching has developed extensively in response to the worldwide phenomenon of migration. Pope Pius XII reaffirms the Church's commitment to caring for pilgrims, aliens, exiles, and migrants of every kind in his apostolic constitution Exsul Familia, affirming that all peoples have the right to conditions worthy of human life and, if these conditions are not present, the right to migrate. "Then — according to the teachings of [the encyclical] Rerum Novarum — the right of the family to a [life worthy of human dignity] is recognized. When this happens, migration attains its natural scope as experience often shows."
While recognizing the right of the sovereign state to control its borders, Exsul Familia also establishes that this right is not absolute, stating that the needs of immigrants must be measured against the needs of the receiving countries:
Since land everywhere offers the possibility of supporting a large number of people, the sovereignty of the State, although it must be respected, cannot be exaggerated to the point that access to this land is, for inadequate or unjustified reasons, denied to needy and decent people from other nations, provided of course, that the public wealth, considered very carefully, does not forbid this.
In his landmark encyclical Pacem in Terris, Blessed Pope John XXIII expands the right to migrate as well as the right to not have to migrate: "Every human being has the right to freedom of movement and of residence within the confines of his own country; and, when there are just reasons for it, the right to emigrate to other countries and take up residence there." Pope John XXIII placed limits on immigration, however, when there are "just reasons for it." Nevertheless, he stressed the obligation of sovereign states to promote the universal good where possible, including an obligation to accommodate migration flows. For more powerful nations, a stronger obligation exists.
The Church also has recognized the plight of refugees and asylum seekers who flee persecution. In his encyclical letter Sollicitudo Rei Socialis, Pope John Paul II refers to the world's refugee crisis as "the festering of a wound." In his 1990 Lenten message, Pope John Paul II lists the rights of refugees, including the right to be reunited with their families and the right to a dignified occupation and just wage. The right to asylum must never be denied when people's lives are truly threatened in their homeland.
Pope John Paul II also addresses the more controversial topic of undocumented migration and the undocumented migrant. In his 1995 message for World Migration Day, he notes that such migrants are used by developed nations as a source of labor. Ultimately, the Pope says, elimination of global underdevelopment is the antidote to illegal immigration. Ecclesia in America, which focuses on the Church in North and South America, reiterates the rights of migrants and their families and the respect for human dignity "even in cases of non-legal immigration."
Both of our episcopal conferences have echoed the rich tradition of church teachings with regard to migration. Five principles emerge from such teachings, which guide the Church's view on migration issues.
I. Persons have the right to find opportunities in their homeland.
All persons have the right to find in their own countries the economic, political, and social opportunities to live in dignity and achieve a full life through the use of their God-given gifts. In this context, work that provides a just, living wage is a basic human need.
II. Persons have the right to migrate to support themselves and their families.
The Church recognizes that all the goods of the earth belong to all people. When persons cannot find employment in their country of origin to support themselves and their families, they have a right to find work elsewhere in order to survive. Sovereign nations should provide ways to accommodate this right.
III. Sovereign nations have the right to control their borders.
The Church recognizes the right of sovereign nations to control their territories but rejects such control when it is exerted merely for the purpose of acquiring additional wealth. More powerful economic nations, which have the ability to protect and feed their residents, have a stronger obligation to accommodate migration flows.
IV. Refugees and asylum seekers should be afforded protection.
Those who flee wars and persecution should be protected by the global community. This requires, at a minimum, that migrants have a right to claim refugee status without incarceration and to have their claims fully considered by a competent authority.
V. The human dignity and human rights of undocumented migrants should be respected.
Regardless of their legal status, migrants, like all persons, possess inherent human dignity that should be respected. Often they are subject to punitive laws and harsh treatment from enforcement officers from both receiving and transit countries. Government policies that respect the basic human rights of the undocumented are necessary.
The Church recognizes the right of a sovereign state to control its borders in furtherance of the common good. It also recognizes the right of human persons to migrate so that they can realize their God-given rights. These teachings complement each other. While the sovereign state may impose reasonable limits on immigration, the common good is not served when the basic human rights of the individual are violated. In the current condition of the world, in which global poverty and persecution are rampant, the presumption is that persons must migrate in order to support and protect themselves and that nations who are able to receive them should do so whenever possible. It is through this lens that we assess the current migration reality between the United States and Mexico.
